Contreras-Sánchez ([email protected]) ABSTRACT. The freshwater drum Aplodinotus grunniens is a species widely distributed in North America. In the Mexican southeast, this species occurs in the Usumacinta River, where it supports an artisanal fishery. In this regard, the present study was conducted to supply detailed information on the female reproductive cycle of this species. Calculations of gonadosomatic (GSI) and hepatosomatic (HSI) indexes, histological and visual staging of ovaries as well as the staging of oocyte development were applied together to determine the reproductive changes during an annual cycle. The histological analysis revealed the presence of spawning capable females throughout the year, and the distribution frequencies of oocyte diameters displayed the continuous occurrence of mature -

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences. -
Zoogeography of Digenetic Trematodes from West African Marine Fishes1
192 PROCEEDINGS OF THE HELMINTHOLOGICAL SOCIETY Zoogeography of Digenetic Trematodes from West African Marine Fishes1 JACOB H. FISCHTHAL Department of Biological Sciences, State University of New York at Binghamton, Binghamton, New York 13901. ABSTRACT: Of the 107 species of trematodes found in West African (Mauritania to Gabon) marine fishes, 100 are allocated to 64 genera in 24 families while seven are immature didymozoids. Many of these genera are located in most of the world's seas with the exception of the polar seas; only five are en- demic to West Africa. The data for the 41 species known from West Africa and elsewhere, and those morphologically closest to the 55 endemic species, indicate that they are very widely distributed, particularly in the Western and North Atlantic, and Mediterranean. Historical and present- day events concerning physical and biological environmental factors and their effects on actual and po- tential hosts as well as on life cycle stages of the trematodes have resulted in the geographical distribution reported. The distribution of marine fishes has been emphasized to explain in part the trematode distribu- tion. Studies on the geographical distribution of (Gulf of Guinea from 5° S to 15° N) and digenetic trematodes of marine fishes in various warm temperate Mauritania have been pre- seas have been presented by Manter (1955, sented by Ekman (1953), Buchanan (1958), 1963, 1967), Szidat (1961), and Lebedev Longhurst (1962), and Ingham (1970).

The digenetic trematodes Of the 107 species of trematodes found in of West African marine fishes (mainly shore West African fishes, 100 are allocated to 64 and shelf inhabitants) have been reported by genera in 24 families while seven are immature Dollfus (1929, 1937a, b, 1946, 1951, 1960), didymozoids of unknown generic status (Ap- Dollfus and Capron (1958), Thomas (1959, pendix I). -

Lengths, weights and condition factors of 39 hybrid juvenile specimen varied between 26.12 and 48.67 mm, 0.7 and 0.99 g, 0.81 and 1.09 respectively. Length-weight relationship (W) was calculated (0.000009 * TL3.006 r = 0.99). Individuals have shown isometric growth (b=3) according to the results of regression analyze by b value. -

CAVIAR AND POLITICS: A RECONSTRUCTION OF RUSSIA’S MARINE FISHERIES IN THE BLACK SEA AND SEA OF AZOV FROM 1950 TO 2010 Esther Divovich, Boris Jovanović, Kyrstn Zylich, Sarah Harper, Dirk Zeller and Daniel Pauly Sea Around Us, Fisheries Centre, University of British Columbia, 2202 Main Mall, Vancouver, V6T 1Z4, Canada Corresponding author : [email protected] ABSTRACT The aim of the present study was to reconstruct total Russian fisheries catch in the Black Sea and Sea of Azov for the period 1950 to 2010. Using catches presented by FAO on behalf of the USSR and Russian Federation as a baseline, total removals were estimated by adding estimates of unreported commercial catches, discards at sea, and unreported recreational and subsistence catches. Estimates for ‘ghost fishing’ were also made, but not included in the final reconstructed catch. Total removals by Russia were estimated to be 1.57 times the landings presented by FAO (taking into account USSR-disaggregation), with unreported commercial catches, discards, recreational, and subsistence fisheries representing an additional 30.6 %, 24.7 %, 1.0%, and 0.7 %, respectively. Discards reached their peak in the 1970s and 1980s during a period of intense bottom trawling for sprat that partially contributed to the large-scale fisheries collapse in the 1990s. -
