La pêche artisanale en lagune Aby-Tendo-Ehy (Côte d'Ivoire): premières estimations de la production

This work is the result of one year of investigations on the artisanal fisheries of the Aby-Tendo-Ehy lagoon. The structure of fish catches varies with the fisheries zones and the fishing gears, but is relatively stable all year along, in the spite of the existence of some species with well worked seasonary cycle. The composition of beach seines catches, which are relatively unselective fishing gears, is: - in the Tendo lagoon (oligohaline) and Ehy lagoon (freshwater): Chrysichthys spp. 35.1%, Tilapia spp. 18.9%, Acentrogobius schlegelii 15.7%, Ethmalosa fimbriata 12% (those are two seasonary species), Tylochromis jentinki 8.8%, Elops lacerta 5.6%, other species 3.9%. - in the south of the Aby lagoon, under tide influence, Ethmalosa fimbriata 79%, Elops lacerta 12%, Chrysichthys spp. 6%, other species 3%. A preliminary estimation of 7900 tons for this lagoon artisanal fisheries total production is made for 1979 (from representative fishing villages) and can be shared as follows: - beach seines: 5300 tons; - purse seines and "syndicat" seines: 2600 tons; individual fishing: not estimated, it mostly concerns fill nets.

Bibliographie des lagunes et du littoral de Côte d'Ivoire (Afrique de l'Ouest)

The present bibliography collects references on lagoon and coastal environments in Côte d'Ivoire. It is mainly based on: - the draft bibliography prepared by Charles-Dominique and Durand in 1979, edited in the Archives Scientifiques du Centre de Recherches Océanographiques d'Abidjan (vol. 5 no. 2); - the synthesis on the marine environment, published in 1993 (LeLoeuff, Marchal and Amon-Kothias editors); - and the synthesis on the lagoon environment, published in 1994 (Durand, Dufour, Guiral and Zabi editors). In spite of a careful check of the available documents, it is more than possible that references are lacking or erroneous. That's why this bibliography is still a draft, and the author will be glad to receive complements and/or corrections from lectors. After these contributions, a more comprehensive version will be proposed. Remarks can be sent to this e-mail: arfi@ortsom.orstom.fr or to the postal address.

Pluralismo, política e julgamento: para um projeto crítico à luz da filosofia de Charles Taylor

O objetivo da tese de doutorado consistirá na defesa de uma alternativa para os dilemas políticos concernentes à incomparabilidade no interior de uma comunidade específica ou entre comunidades distintas, presente nas discussões em torno do pluralismo contemporâneo. Esta via é inspirada nos conceitos de bens constitutivos, avaliações fortes e articulação, desenvolvidos pelo filósofo canadense Charles Taylor, e é também uma tentativa de se pensar acerca de um projeto de crítica política que leve em consideração a motivação como elemento incontornável para a filosofia prática. A incomparabilidade, isto é, impossibilidade de critérios no julgamento entre práticas específicas, mas com repercussões públicas, levanta a questão de até que ponto é possível avaliar e deliberar racionalmente sobre modos de vida distintos e, às vezes, auto-excludentes. Tal problemática pode ser vista fortemente no chamado debate liberal-comunitarista, na década de 1980, bem como em seus desdobramentos nas discussões acerca do multiculturalismo, na década seguinte. E ainda, mais recentemente, nos impasses em torno do papel da religião na esfera pública. Mais do que pontos divergentes acerca da questão do julgamento, os que essas discussões também evidenciam é um debate mais central acerca do lugar que pode ocupar a política diante de nossa situação bem como as categorias pelas quais compreendemos o fenômeno do pluralismo. Sob a alcunha de comunitarista, o pensamento de Taylor aparece como uma forma atrativa por não se submeter ao relativismo (a impossibilidade de critério) e tampouco a um universalismo forte (baseado em critérios gerais e anteriores às práticas), ao desenvolver uma ontologia fundada em um conflito de bens constitutivos em disputa, sem desconsiderar o fenômeno do pluralismo. Com efeito, isto se dá na medida em que diante de práticas divergentes e concorrentes há implícita ou explicitamente uma posição acerca de como e a partir de onde podemos nos posicionar criticamente frente ao pluralismo vigente, uma vez que movimentos, discursos e relações são construídos em nome daquilo que se apresenta efetivamente como valioso ou digno de respeito e admiração. Neste sentido, qualquer tentativa de avaliação já diz respeito a nossa compreensão: de nós, do mundo e de nossa relação com o mundo. Um projeto crítico, levando em consideração nossas fontes que impulsionam a ação, requer um olhar detalhado que o pensamento de Taylor pode oferecer, especialmente a partir da relação entre os conceitos supracitados.

Drawn to the Sea: Charles Bradford Hudson (1865-1939), Artist, Author, Army Officer, with Special Notice of His Work for the United States Fish Commission and Bureau of Fisheries

The biography of Charles Bradford Hudson that follows this preface had its seeds about 1965 when I (VGS) was casually examining the extensive files of original illustrations of fishes stored in the Division of Fishes, National Museum of Natural History, Smithsonian Institution. I happened upon the unpublished illustration of a rainbow trout by Hudson and was greatly impressed with its quality. The thought occurred to me then that the artist must have gone on to do more than just illustrate fishes. During the next 20 years I occasionally pawed through those files, which contained the work of numerous artists, who had worked from 1838 to the present. In 1985, I happened to discuss the files with my supervisor, who urged me to produce a museum exhibit of original fish illustrations. This I did, selecting 200 of the illustrations representing 21 artists, including, of course, Hudson. As part of the text for the exhibit, Drawn from the Sea, Art in the Service of Ichthyology, I prepared short biographies of each of the artists. The exhibit, with an available poster, was shown in the Museum for six months, and a reduced version was exhibited in U.S. and Canadian museums during the next 3 years.

Stanford University’s John Otterbein Snyder: Student, Collaborator, and Colleague of David Starr Jordan and Charles Henry Gilbert

John Otterbein Snyder (1867–1943) was an early student of David Starr Jordan at Stanford University and subsequently rose to become an assistant professor there. During his 34 years with the university he taught a wide variety of courses in various branches of zoology and advised numerous students. He eventually mentored 8 M.A. and 4 Ph.D. students to completion at Stanford. He also assisted in the collection of tens of thousands of fish specimens from the western Pacific, central Pacific, and the West Coast of North America, part of the time while stationed as “Naturalist” aboard the U.S. Fish Commission’s Steamer Albatross (1902–06). Although his early publications dealt mainly with fish groups and descriptions (often as a junior author with Jordan), after 1910 he became more autonomous and eventually rose to become one of the Pacific salmon, Oncorhynchus spp., experts on the West Coast. Throughout his career, he was especially esteemed by colleagues as “a stimulating teacher,” “an excellent biologist,” and “a fine man.

Charles H. Gilbert, Pioneer Ichthyologist and Fishery Biologist

Charles Henry Gilbert (Fig. 1) was a pioneer ichthyologist and, later, fishery biologist of particular significance to natural history of the western United States. Born in Rockford, Illinois on 5 December 1859, he spent his early years in Indianapolis, Indiana, where, in 1874, he came under the influence of his high school teacher, David Starr Jordan (1851-1931). Gilbert graduated from high school in 1875, and when Jordan became a professor of natural history at Butler University in Irvington, Indiana, Gilbert followed, and received his B.A. degree in 1879. Jordan moved to Indiana University, in Bloomington, in the fall of 1879, and Gilbert again followed, earning his M.S. degree in 1882 and his Ph.D. in 1883 in zoology. His doctorate was the first ever awarded by Indiana University.

Charles Henry Gilbert (1859-1928), Naturalist-in-Charge, and Chauncey Thomas, Jr. (1850-1919), Commanding: Conflict Aboard the U. S. Fish Commission Steamer Albatross in 1902

Charles Henry Gilbert (1859-1928) was a pioneering ichthyologist who made major contributions to the study of fishes of the American West. As chairman of the Department ofZoology at Leland Stanford Junior University in Palo Alto, Calif., during 1891-1925, Gilbert was extremely devoted to his work and showed little patience with those ofa different mindset. While serving as Naturalist-in-Charge of the U.S. Fish Commission Steamer Albatross during her exploratory expedition to the Hawaiian Islands in 1902, Gilbert engaged in an acrimonious feud with the ship's captain, Chauncey Thomas, Jr. (1850-1919), U.S.N., over what Gilbert perceived to be an inadequate effort by the captain. This essay focuses on the conflict between two strong figures, each operatingf rom different world views, and each vying for authority. Despite the difficulties these two men faced, the voyage of the Albatross in 1902 must be considered a success, as reflected by the extensive biological samples collected, the many new species of animals discovered, and the resulting publication of important scientific papers.
