KARTA JAYA | 3/17/2012 | 0 komentar |
Dalam dunia perikanan sangat penting untuk mengetahui tingkah laku ikan terhadap respon yang diberikan kepada ikan. Respon ikan inilah yang menjadi pokok permasalahan para ilmuan sehingga menciptakan alat-alat yang berfungsi untuk mengamati tingkah laku ikan terhadap aksi yang kita berikan kepada ikan. Usaha untuk mempelajari tingkah laku ikan ikan ini sangat erat hubungannya dengan mempelajari pengembangan alat penangkapan ikan. Untuk mengetahui alat-alat apa saja yang digunakan untuk mengetahui atau mengamati tingkah laku ikan dapat sobat lihat di bawah ini.

1. Batistat
Peralatan ini digunakan untuk melihat tingkah laku ikan hingga laut dalam.Umumnya berbentuk silinder atau bola berongga dan terbuat dari bahan logam yang kuat. Alat ini dimasukkan ke dalam air; pasif ataupun ditarik oleh kapal. Dilengkapi dengan system penerangan dan penutup yang kedap air, system komunikasi untuk tetap menjaga agar tetap ada hubungan antara peneliti yang ada di dalam batistat dengan mereka yang ada di kapal.

2. Batiskap
Peralatan (free diving) dapat bergerak sendiri yang dihubungkan dengan kapal melalui tali baja yang kuat, mempunyai perlengkapan electromotor
yang memungkinkan bekerjanya propeller, sehingga mampu bergerak sendiri dengan kecepatan beberapa knot.Batiskap dapat bergerak ke permukaan maupun jauh ke dalam laut sejauh panjangnya tali baja penghubung dengan kapal. Dengan alat ini PICCARD melakukan penelitian untuk melihat tingkah laku ikan hingga pada kedalaman 11.000 meter di bawah laut.

3. Kapal Selam
Pengamatan langsung yang sangat modern dewasa ini adalah dengan menggunakan kapal selam.Salah satu kapal selam yang telah digunakan untuk mengungkapkan tingkap laku ikan herring di samudera Atlantik Utara adalah kapal selam “Severyanha” yang dimodifikasi untuk penelitian ilmiah.


4. Televisi, Film dan Pemotretan Bawah Air
Dengan peralatan ini, peneliti dapat melakukan pengamatan yang lebih teliti denganmelihat berulang kali hali rekamannya baik untuk pengamatan komposisi kelompok ikan,aktifitas, serta tingkah laku lainnya yang diperlukan dalam mendetrminasi, ukuran,komposisi, tingkat kepadatan dan sebagainya yang diamati saat ditayangkan
5. Fish Finder
Kebiasaan atau tingkah laku ikan dalam pengelompokan dapat diketahui. laku ini dalam hubungannya dengan faktor lingkungan atau stimulus yangdiberikan dan menjadi dasar dalam pengoperasian peralatan tangkap (Misalnya dari hasil deteksi di ketahui adanya kelompok ikan pada kedalaman tertentu, maka keputusan pengoperasian jenis alat tangkap dan kedalamannya dapat diambil untuk mengoptimalkan hasil tangkapan).

6. Water Tonic (Aquarium)
Aquarium merupakanperalatan yang digunakan dalam pengamatan tingkahlaku ikan tempat ikan diamati.Alat ini bisanya terbuat dari bahan kaca yang disisi air.

7. Mini Flume Tank
Alat ini merupakan flume tank dalam betuk kecil yang fungsinya untuk pengamatan performance ikan, mengetahui cara renang ikan, gaya renang ikan, cara makan ikan dan lain sebaginya. Alat ini terbuat dari kaca yang dimodifikasi dengan alat-alat tertentu seperti penambahan cahaya lampu dan pegatur arus.

8. ROV (Remote Operated Underwater Vehicle)
Alat ini digunakan dalam mengamati tingkah laku ikan pada dasar laut dangkal, karena dilengkapi dengan video kamera bawah air, mengamati penempatan pipa bawah air yang diletakkan di rancang untuk memantau kondisi bawah air, khususnya dalam penempatan objek bawah air, misalnya rumah ikan (fish shelter) atau rumpon bawah air.


9. Underwater TV Kamera
Alat ini dirancang khusus untuk memotret apa yang terjadi dalam perairan ketika pengamatan. Terdiri dari kabel kedap air, rumah kedap air, lampu infra red.

10. Mesin Embedding (Histocembedder)
Mesin ini digunakan dalam proses embedding. Mesin ini terdiri atas bagian-bagian antara lain cashbath, paraffin tank, cold plate, hot plate, dan vacuum oven.

ABALONE dan BINTANG ULAR (Ophiuroidea)

KARTA JAYA | 3/16/2012 | 0 komentar |
Abalon
Abalon (berasal dari bahasa Spanyol, Abulón) ialah suatu spesies kerang-kerangan (moluska) dari familia Haliotidae dan genus Haliotis. Ia dikenal pula sebagai kerang mata tujuh atau siput balik batu, ormer di Jersey dan Guernsey, perlemoen di Afrika Selatan, dan pāua di Selandia Baru.
Abalon tergolong dalam kelas Gastropoda yang besar. Terdapat hanya satu genus dalam famili Haliotidae dan kira-kira 4 - 7 subgenus. Taksonominya agak membingungkan. Spesiesnya berjumlah antara kira-kira 100 hingga 130 (karena adanya hibrida).
Abalon memiliki ciri-ciri permukaan kulit sebelah dalam yang berwarna-warni yang terbuat dari nakre. Daging moluska ini dianggap sebagai salah satu makanan istimewa di sebagian Amerika Latin (khususnya Chili), Asia Tenggara, dan Asia Timur (khususnya di Republik Rakyat Cina, Jepang, dan Korea).

 Kerang Abalone biasa ditemukan pada daerah yang berkarang yang sekaligus dipergunakan sebagai tempat menempel. Kerang abalone bergerak dan berpindah tempat dengan menggunakan satu organ yaitu kaki. Gerakan kaki yang sangat lambat sangat memudahkan predator untuk memangsanya. Pada siang hari atau suasana terang, kerang abalone lebih cenderung bersembunyi di karang-karang dan pada suasana malam atau gelap lebih aktif melakukan gerakan berpindah tempat. Ditinjau dari segi perairan, kehidupan kerang abalone sangat dipengaruhi oleh kualitas air. Secara umum, spesies kerang abalone mempunyai toleransi terhadap suhu air yang berbeda-beda, contoh; H. kamtschatkana dapat hidup dalam air yang lebih dingin sedangkan H. asinina dapat hidup dalam air bersuhu tinggi (300C).
Penyebaran kerang abalone sangat terbatas. Tidak semua pantai yang berkarang terdapat kerang abalone. Secara umum, kerang abalone tidak ditemukan di daerah estuaria yaitu pertemuan air laut dan tawar yang biasa terjadi di muara sungai. Ini mungkin disebabkan oleh beberapa faktor, diantaranya adanya air tawar sehingga fluktuasi salinitas yang sering terjadi, tingkat kekeruhan air yang lebih tinggi dan kemungkinan juga karena konsentrasi oksigen yang rendah. Kerang abalone merpakan hewan herbivore, yaitu hewan pemakan tumbuh-tumbuhan dan aktif makan pada suasana gelap. Jenis makanannya adalah seaweed yang biasa disebut makro alga. Jenis seaweed/makro alga yang tumbuh dilaut sangat beraneka ragam. Secara garis besar ada 3 golongan seaweed/makro alga yang hidup di laut, yaitu; 1) makro alga merah (Red seaweeds), 2) alga coklat (Brown seaweeds), dan 3) alga hijau (Green seaweed). Ketiga golongan tersebut terbagi atas beberapa jenis dan beraneka ragam. Keragaman tersebut tidak semuanya dapat dimanfaatkan kerang abalone sebagai makanannya.

Haliotis australis, Haliotis ancile, Haliotis aquatilis, Haliotis asinina, Haliotis barbouri, Haliotis brazieri, Haliotis clathrata, Haliotis coccoradiata, Haliotis sorenseni, Haliotis conicopora, Haliotis corrugata, Haliotis cracherodii, Haliotis crebrisculpta, Haliotis crebrisculpta, Haliotis cyclobates, Haliotis dalli, Haliotis discus, Haliotis dissona, Haliotis diversicolor supertexta, Haliotis diversicolor, Haliotis dohrniana, Haliotis elegans, Haliotis emmae, Haliotis ethologus, Haliotis exigua, Haliotis fatui, Haliotis fulgens, Haliotis gigantea, Haliotis glabra, Haliotis hargravesi, Haliotis howensis, Haliotis iris, Haliotis jacnensis, Haliotis kamschatkana, Haliotis kamtschatkana assimilis, Haliotis kamtschatkana kamtschatkana, Haliotis laevigata, Haliotis madaka, Haliotis mariae, Haliotis melculus, Haliotis midae, Haliotis multiperforata, Haliotis ovina, Haliotis corrugata.


Ophiuroidea
Bintang ular adalah hewan dari filum Echinodermata, yang memiliki hubungan dekat dengan bintang laut. Mereka berjalan di dasar laut dengan menggunakan lengan fleksibel mereka untuk bergerak. Bintang ular umumnya memiliki lima lengan berbentuk seperti cambuk yang panjangnya bisa mencapai 60 cm (2 kaki) pada spesimen terbesar. Ada sekitar 1.500 spesies bintang ular yang hidup sekarang, dan mereka kebanyakan ditemukan pada kedalaman lebih dari 500 meter (1.620 kaki).
Bintang ular dapat ditemukan pada perairan besar, dari kutub sampai tropis. Berdasarkan fakta, lili laut, teripang, dan bintang ular merajai dasar laut pada kedalaman lebih dari 500 meter, di seluruh dunia. Basket star biasanya terdapat di wilayah yang lebih dalam.

Seperti echinodermata lainnya, Ophiuroidea memiliki rangka dari kalsium karbonat. Bentuk tubuh bintang ular mirip dengan Asteroidea. Kelima lengan ophiuroidea menempel pada cakram pusat yang disebut calyx.Ophiuroidea memiliki lima rahang. Di belakang rahang ada kerongkongan pendek dan perut besar, serta buntu yang menempati setengah cakram. Ophiuroidea tidak memiliki usus maupun anus. Pencernaan terjadi di perut. Pertukaran udara dan ekskresi terjadi pada kantong yang disebut bursae. Umumnya ada 10 bursae.Kelamin terpisah pada kebanyakan spesies. Ophiuroidea memiliki gonad. Gamet disebar oleh bursal sacs. Sistem saraf terdiri atas cincin saraf utama yang bekerja di sekitar cakram utama. Ophiuroidea tidak memiliki mata, atau sejenisnya. Tetapi, mereka memiliki kemampuan untuk merasakan cahaya melalui reseptor pada epidermis. Baik Ophiurida maupun Euryalida memiliki lima lengan yang panjang, langsing, fleksibel, dan berbentuk seperti cambuk. Mereka dibantu dengan rangka internal yang terbuat dari kalsium karbonat.Pembuluh dari sistem vaskular air berakhir di kaki tabung. Sistem vaskular air umumnya memiliki satu madreporit. Kaki tabung tidak memiliki penghisap dan ampulla.Ophiuroidea memiliki kemampuan untuk meregenerasi kaki yang putus. Ophiuroidea menggunakan kemampuan ini untuk melarikan diri dari predator, seperti kadal, yang mampu memutuskan ekor mereka untuk membingungkan pengganggu.
Bintang ular menggunakan lengan mereka untuk bergerak. Mereka, tidak seperti bintang laut, bergantung pada kaki tabung. Bintang laut bergerak dengan menggerakan lengan mereka yang sangat fleksibel dan membuat mereka bergerak seperti ular. Pergerakan mereka mirip dengan hewan simetri bilateral.
Pernapasan dilakukan oleh 5 pasang kantong kecil yang bercelah di sekitar mulut, alat ini berhubungan dengan saluran alat reproduksi (gonad).
Alat-alat pencernaan makanan terdapat dalam bola cakram, dimulai dari mulut yang terletak di pusat tubuh kemudian lambung yang berbentuk kantong. Hewan ini tidak memiliki anus. Di sekeliling mulut terdapat rahang yang berupa 5 kelompok lempeng kapur.Makanan dipegang dengan satu atau lebih lengannya, kemudian dihentakkan dan dengan bantuan tentakel dimasukkan ke mulut. Sesudah dicerna, bahan-bahan yang tidak tercerna dibuang ke luar melalui mulutnya.
Jenis kelamin hewan ini terpisah. Hewan ini melepaskan sel kelamin ke air dan hasil pembuahannya akan tumbuh menjadi larva mikroskopis yang lengannya bersillia, disebut pluteus. Pleteus kemudian mengalami metamorfosis menjadi bentuk seperti bintang laut dan akhirnya menjadi bintang ular.

History of Ichthyology

KARTA JAYA | 3/16/2012 | 0 komentar |
INTRODUCTION
The Holy Bible is the first book that declared Adam as the first person to name species. However since this web site is dealing with recorded scientific information we must forego the theological path and instead focus on Man's ichthyologic method record. The sciences essentially began in Europe and later works in the New World were to advance European sciences. For practical purposes, science is still relatively young in the Americas. Many overlooked works can be found in manuscripts by Christopher Columbus who wrote about the fauna he saw in the New World or the Egyptians who catalogued their fishes on pyramid walls. Even Leif Ericsson's explorations which predated Columbus had mention of fishes that later scientist's would "discover." But even with this knowledge of history, we mustn't overlook the aborigines who themselves named species. Some of which bear the native name in the species binomen.
The beginning of taxonomy can be probably traced to John Ray (1628-1705). Ray introduced the complex grouping system and greatly improved the language description. Ray used the genus and species method of naming organisms. Prior to that the Greeks and Romans, notably Aristotle (384-322 B.C.) is credited with starting taxonomy having an accurate knowledge of fish anatomy and able to correctly distinguish aquatic mammals or cetaceans. But it was the work of the next author that drew the most praise and credit.
Karl Linnaeus (1707-1778) brought sharp focus to the method used today. Linnaeus (see picture at left) is considered by all as the "father" of taxonomy. It was his work that was massive in its undertaking, surpassing all before him including Ray. Linnaeus created a system of keys for naming species that were simple to use. This enabled many to use the method to identify organism's themselves. Linnaeus first classification of nature (minerals, plants and animals) appeared in 1735 and was immediately accepted by his peers. He grew in stature and reputation throughout the world. Later, he would establish a school (University of Upsala) in Sweden, which became the center of taxonomony which students from all over the world came. He called his work Systema Naturae. This work was in its 13th edition when Linnaeus died in 1778, this work however was carried over through more editions by his students for the next 50 years. Modifications took place over time following the method first established by Ray. By the 10th edition the list of names and species became shorter and shorter to its abbreviated form. Linnaeus suggested that it was sufficient it if merely identified the species among those of the genus. This simple answer established the binominal system of nomenclature.
Linnaeus further gave names to groups larger than the genus, establishing the class (similar to what Aristotle had established). The first was called CLASSES and each was divided into ORDERS, which then were broken down further to genera and species. By 1800 other workers introduced FAMILY as a category between ORDER and the genus. Finally, the classes were grouped into higher categories called PHYLA.
The 10th edition of Systema Naturae is the first publication to adhere strictly to binominal nomenclature, one of the International Rules states that no name published prior to this is valid. Hence, the 4,236 descriptions in this book include the earliest species are considered and accepted as official. The International Rules of Zoological Nomenclature require that whenever a new species is discovered and described the name of the designated species must be called a Holotype on which the species is based. Other species used in describing the new species become paratypes, and the data collected from them is included in the description. It is customary for ichthyologists to give the designated type to (country of origin) museums for permanent preservation. This then can be reviewed and used for research by professional ichthyologists and students who are qualified.
But problems would begin to surface that would lead to more changes and a new burst of interest in this work. The 19th century saw rise of a period called "romanticism" and a philosopher by the name of Johann Wolfgang von Goethe paved the way in city-state of Weimar in Germany. He was a poet and a biologist among other things. His belief in harmony and the inherent goodness of nature started a new trend which was called "nature-philosophy" as a method understanding life. This however did not last long as the generation began to mature more. Georges Cuvier was a biologist in France (survived not only the French Revolution but Napoleon too) and extended single-handedly a new method of classification called comparative anatomy. By reconstructing bones of extinct animals (fossils) he began the laborious task of naming them. This resurgence however did not last long even though Cuvier work uncovered many things that were once considered distinct. The concept of evolution was not accepted nor popular at the time and Cuvier et al., were vehemently opposed to it. The thought of those days was that all creatures were created just as they were. The original method of Linnaeus had not been realized yet and taxonomy declined after 1832.
Charles Darwin entered the arena in 1858 and by that time taxonomy was facing its worst crises, lack of interest by scientists. When Darwin presented his ideas and arguments about evolution eyes perked up and now a newer method was being devised. In Cuvier's time evolution would have been unthinkable and unscientific. Even by today's standards Darwinism as it was known then postulated that man descended from a common ancestor, the ape. This was met with much controversy even court action to prevent schools to teach was is now called "Evolution." Darwin was able to postulate the "why" of a species where before it could never be asked. This allowed a species to be better defined as an evolutionary unit, as well as a taxonomic category.
Ichthyology
Ichthyology which is the focus of this OPEFE website was confronted with many inadequate descriptions and figures of fishes printed during the over 200 years since records were first kept. The first original observations may be attributed to Pierre Belon (1517-1575) in De aquatilibus libri duo; Hyppolyto Salviana (1514-1572) in Aquatilium animalium histoae...; and Gulielmus Rondelet (1507-1566) in libri de piscibus marinis, whose works are almost entirely limited to Mediterrean and European fishes.The next century, Guilielmus Piso (1611-1678) and George Marcgrav (1610-1644) accompanied Prince Moritz of Nassau (1604-1679) to Brazil in 1637-1644 approximately 100 species of fish. It was about this time John Ray (see above) and Francis Willoughby (1635-1672) and ichthyology flourished.
A Swede by the name of Peter Artedi (1705-1735) surfaced from the University of Uppsala, Sweden. His earliest investigation were more important than others before him. There are those who consider him the father of ichthyology. In 1728 Karl (Latinized as Carolus) Linnaeus visited this university. Linneaus inquired as to who was engaged in the study of natural history and he was then referred to Artedi. That is how they met and became friends. Each helping the other not only in personal money needs but even making an agreement that the survivor would publish the works of the one deceased. Artedi drowned in 1735 in Holland. Linnaeus true to his word published Artedi Ichthyologia in 1738. Artedi method was that he believed that a genus represented a group of species which agreed with each other in general but which differed in minor characters. Having established the generic concept, Artedi proceeded to group the genera into "maniples." This is the same family concept used today. The maniples were arranged into natural orders, and these into a class, representing the whole group of fishes. In all Artedi recognized 47 genera and 230 species. The only weakness in this rating was below the genus. He retained the polynomial scheme of nomenclature. There is no doubt Artedi greatly influenced Linnaeus.
Many more ichthyologic works would follow Artedi and Linnaeus. Some of those names include, Otto Fabricus (1744-1822), Petrus Forskål (1736-1763), Petrus Pallas (1741-1811), Antione Risso (1777-1845), Thomas Pennant (1726-1798), Wlhelm G. Tilesius (1769-1857), Georg Wilhelm Steller (1709-1746). Constantine Samuel Rafinesque (1783-1840), had the dubious distinction of having described and published non-existent animals. This as a result of a friend suggesting the famed bird painter Audobon meet Rafinesque since both shared a passion for natural history. This was during the summer and Rafinesque having impressed Audobon with his knowledge of natural history was invited to spend the night in Audobon's cabin. During the night, Audobon awoke to a commotion in the naturalist room. To his astonishment he saw his guest, running naked, holding the handle of Audobon's favorite Cremona (a violin), the body of which was battered to pieces in attempting to kill bats for examination. Audobon as earlier stated was a noted artist and famous for painting birds. He used this skill to create non-existent animals by placing the head of one and then painting onto the body of another. Perhaps revenge in his heart Audobon gave these paintings to Rafinesque and the naturalist immediately set out in describing these new species. Ten of these were actually published in Ichthyologia Ohiensis.
Marc Elieser Bloch (1723-1799), Bernhard G.E. Lacepède (1756-1825), Georges L. C. F.D. Cuvier (1769-1832) and Achille Valenciennes (1794-1865). The first ichthyologist to publish an actual description can be traced to an American named LeSueur (1821). The species described was Mollinesia latipinna, commonly called the sail-fin Mollie. In those days there was a lot of carelessness in describing and naming new species. Many of the plates used as illustrations contained many errors in spelling, etc. Because the egregious mistake in spelling of Mollinesia was in dispute (the plate illustration had the name misspelled as Molinesia) it took three ichthyologist in the future to investigate and correct the nomenclature error.
The last attempt to write a series of volumes on the fishes of the world was by Albert C.L.G. Günther (1830-1914). This work was entitled Catalogue of the Fishes of the British Museum. It was published in eight volumes from 1859-1870. To many species were being discovered and the task became more complicated. More work than one person could accomplish. The local fauna was by and large greater than what was once thought and could not be worked into the treatise on fishes of the world. The next serious attempt was made by Johann Baptis von Spix (1781-1826) and Louis Aggassiz (1807-1873). This work pertained to Brazilian local fauna and related fishes. Johann Müller (1801-1858) and Friedrich G. J. Henle (1807-1885) produced the first authoritative work on sharks (Systematische Beschriebungen der Plagiostomen) in 1841. Peter Bleeker (1819-1878) published 500 separate contributions, chiefly on the fishes of the tropical Indo-Pacific. His book which was not only fully illustrated, it was one of the best 9 volumes from previous works of other authors. The book name is Atlas Ichthyologique des Indes Orientales Néerlandaises, 1862-1877. The literature from that work is the most accurate and comparable to many literature found today.
Cuba also had a notable ichthyologist by the name of Felipe Poey y Aloy (1799-1891). He labored for over a 50 years on the local fish and fauna. Japan also produced other ichthyologic works by Coenraad Jacob Temminck (1770-1858) and Herman Schlegel (1804-1844). Their work catalogued the fauna and fishes of the Japanese island. There were other ichthyologists from other lands (way to many to list here), but some other notable ones include; Franz Steindachner (1834-1919), George Boulenger (1858-1937), Robert Collett (1842-1913), Carlos Berg (1843-1902), Francis Day (1829-1889), and Leon Louis Vaillant (1834-1915).
American Ichthyology is dated from the feeble beginnings of Rafinesque and from Samuel Latham Mitchill (1764-1831). His work pertained to the treatise on the fishes of New York. Shortly after that Charles Alexander LeSueur (1778-1846) reported on the Great Lakes and Ohio basin. He was an artist and naturalist. Other American ichthyologist surfaced during that period; Jared Potter Kirtland (1793-1877) on Ohio fishes; James Ellsworth DeKay (1792-1851) on the New York fauna; John Richardson (1787-1865), published Fauna boreali-Americana in 1836. Massachusetts also produced an ichthyologist named David Humphreys Storer (1804-1891) who focused his work on the fishes from that state. South Carolina fishes were examined and written about by John Edwards Holbrook (1796-1871).
In 1846, The Smithsonian Institution was created in the city of Washington, D. C. This institution was under the direction of the United States government. This gave a permanent residence to the United States National Museum where specimens could stored and later reviewed by people interested in North American fauna and the fauna found in the world. The U.S. National Museum, Division of Fishes is so large that very little space is available for its multitude of specimen jars exceeding 300,000. This collection belongs to the people of the United States and is available only those students qualified in ichthyologic studies. This collection is very similar to a book library where the student can research past observations and record new ones. The institution is assisted by the U.S. Fish and Wildlife Commission who has a history of systematic ichthyologic leadership in investigations over a century old. Noteworthy contributions can be traced to G. Brown Goode (1851-1896) and his Oceanic Ichthyology; David Starr Jordan (1851-1931) in collaboration with Charles Henry Gilbert (1859-1928) and Barton Warren Evermann (1853-1932) were responsible for publishing over 100 citations on American fishes. Henry W. Fowler (1878-?), Academy of National Sciences in Philadelphia, did many citations on Philippine collections using his on ship called Albatross. Furthermore, Fowler in 1945 and Bailey & Miller in 1950 examined the work by LeSeur amended the name to Mollienesia which closely followed the name of the man it was supposed to honor, LeSueur. This was the first time an examination of ichthyologic review was ever done in order to correct an egregious error in a citation. A volume of fishes in Peru was provided by Samuel Frederick Hildebrand (1883-1949) and that on freshwater fishes of Thailand (then Siam) by Hugh McCormick Smith (1865-1941).
Louis Agassiz (1807-1873) in 1850 wrote a monograph on the fishes of Lake Superior and trained one of his students, Charles Frederic Girard (1822-1895), in ichthyology. Many fish collections and preservations were completed during the United States Pacific Railway surveys which were brought back to Washington. Here Spencer Fullerton Baird (1823-1887) published the survey fauna (mostly from the Western United States) with the assistance of Girard. Baird was one of the secretaries to the Smithsonian Institution during this time. Also engaged in these earlier explorations were James Wood Milner (1841-1879), Marshall McDonald (1835-1895), William O. Ayers (1817-1891), William Neale Lockington (184?-1902), and George Suckley (1830-1869) among others.
Certain American educational institutions (latter half of nineteenth century and early twentieth century) later arose into centers of leadership in the study of fishes and exploration. Harvard University had Samuel Garman (1843-1927). Garmon was a student of Agassiz and he made valuable contributions on the sharks and the deep-sea fishes collected by Albatross. Indiana University became another important research center for fishes under the leadership of David Starr Jordan during the 1880's. He would be then followed by the man whom many would call "the father of characid studies," Carl Eigenmann.
Carl H. Eigenmann (1863-1927) took over and became famous for his valuable contributions on South American fishes. Jordan had trained Eigenmann and inspired his very active ichthyologic career. Eigenmann collaborated in many of Jordan's works and Jordan would later appoint Eigenmann as professor of zoology at Indiana University. Upon Eigenmann's death his successor (Fernandus Payne) praised Eigenmann's researches by stating in his opinion "place him (Eigenmann) in the first rank of ichthyologists of all time." Jordan praised Eigenmann by saying "one of the most eminent workers in the field of systematic zoology and one of the ablest of natural history teachers, withal the most tireless of explorers." Jordan in the meantime left Indiana and took over as first president of Stanford University, California. His leadership in establishing a fish center there is still strong today. When he left Indiana he took with him Charles Henry Gilbert (1859-1928). At Stanford he gathered two important men, John Otterbein Snyder (1867-1943) and Edwin Chapin Starks (1867-1932). For half a century Standford University was the main center for training students in ichthyology. Charles Henry Gilbert was known for his methodical handling of American fishes. His work was primarily on salmon and to apply statistical methods to fishery research. This earned him the title of "the father of modern fisheries biological research in America."
Seth John Meeks (1859-1914) was another of Jordan's students and like Eigenmann revised many early group and regional papers. He largely focused his attention on freshwater fishes of Middle America. Many more followed Jordan's lead and most were his students. George Brown Goode (1851-1896) played an important role in pure and applied ichthyology in the United States. His ichthyology overlapped Jordan, but the two did not publish together. However, they did cooperate effectively. Much of his work was focused on fisheries biology, particularly that of certain commercially important fishes. His research of deep-sea fishes was firmly established since Jordan had no interest in them. Tarleton H. Bean (1846-1916) was an associate of Goode and helped lay out the rational inclusion of deep-sea fishes in the Fishes of North and Middle America. Later Bean's brother Barton A. Bean (1860-1947) followed him as Curator of Fishes in the National Museum. However his reign seemed to be (quoting from Carl L. Hubbs) "less productive and less illustratrious scientific life (during slightly more than the last decade of the nineteenth century and the first two decades of the twentieth)."
Louis Agassiz while in San Francisco picked up another fellow by the name of Samuel Garman (1843-1927) from what was then called "the Wild West." Agassiz trained Garman in ichthyology (both Garman and Jordan were fellow students under Agassiz at Penikese). In addition to publishing a considerable number of minor papers, Garman monographed the "Discoboli" (Cyclopteidae and Liparididae) in 1892, and the Cyprinodontes in 1895. Garmon's work methodical in his attention to the anatomical detail. However, he was never admired nor a member of the Jordan clique. Garmon was indeed a recluse, locking himself into his ill-lit quarters at MCZ. The period 1875-1900 knowledge of fish fauna of the Pacific Coast of the United States flourished. Several incidental studies were conducted by Louis and Alexander Agassiz, Gill, William O. Ayres, James Grahm Cooper (1830-1902), William Gibbons (1812-1897), and a few other lessor known figures. Much of the work reached a standstill during the Pacific Railroad Survey of the 1850's. That is until Jordan and Gilbert carried out their survey in 1880. The collected from British Columbia to San Diego, chiefly fish markets, which then, especially in California, contained a wide variety of inshore fishes.
This were quickly returned to their hotel room where they prepared the fishes for shipment in preservative. Many quick descriptions were done this way with prompt publication following their discovery. These were published in short papers in the Proceedings of the United States National Museum for 1880 and 1881. Never mind, that expediency for correct descriptions was the norm and this would later create problems for ichthyologists to follow. In one situation on a trip to Matzatlán and on two trips to Panamá, in 1881 and 1882, Gilbert made large fish collections that were destroyed by fire. This before a monograph on The Fishes of the Pacific Coast of Tropical America could be written!
