Sound production in Sciaenidae spp. : the relationship between acoustic activity and spawning in an aquaculture perspective. © Marta Bolgan Aurora Crucianelli 2017-2018 Promoteurs Eric Parmentier - Marta Bolgan Présidente du jury Sylvie Gobert Jury Orphal Colleye - Carole Rougeot - Michaël Ovidio Abstract During this study, sound production of three Sciaenidae species (Argyrosomus regius, Umbrina cirrosa and Sciaenops ocellatus) was investigated before (t0 and t1) and during spawning season (t2) in rearing facilities. The study showed a clear increase in calling activity during the spawning season and changes in the acoustic parameters in all three species. A shift in the diel pattern of sound production before and during reproduction was observed in all three species. The calling activity out of reproductive season was mainly emitted during daytime hours whereas calls emitted during the reproduction season occurred mainly during nighttime hours. Fine acoustic parameters like number of pulses and pulse period seemed indicative of spawning as more quickly repeated pulses were found during the reproductive season. This implies that the sonic muscles contract faster during reproduction which was supported by the increase in sarcoplasmic reticulum on analyzed cross-sections. Résumé Durant cette étude, la production sonore de trois espèces de Sciaenidae (Argyrosomus regius, Umbrina cirrosa et Sciaenops ocellatus) a été investiguée dans une aquaculture avant (t0 et t1) et durant la période de reproduction (t2). L’étude a pu démontrer une augmentation significative de la production sonore pendant la période de reproduction ainsi que des changements dans les paramètres fins pour les trois espèces étudiées. Un changement dans la production sonore journalière a été observé chez les trois espèces entre la période non reproductive et la saison de reproduction. En dehors de la période de reproduction, la production sonore était principalement émise durant les heures diurnes alors que les sons émis durant la saison d’accouplement survenaient principalement durant les heures nocturnes. Les paramètres fins tels que le nombre de pulsations et la période de pulsation semblaient indicatifs de ponte sachant que des sons avec plus de pulsations et plus souvent répétées ont été obtenus lors de la saison de reproduction ce qui implique que les muscles soniques se contractent plus rapidement durant la saison de ponte. Ceci est appuyé par l’augmentation du réticulum sarcoplasmique en coupe transversale.

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

  • 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).

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.
