Feeding behaviour of adult European anchovy (Engraulis encrasicolus) was studied in the Gulf of Lions (northwestern Mediterranean Sea) in relation to major abiotic and biotic factors. Observations were made during the main spawning period (summer) for two years, data were collected through hydrological pro-tiling, zooplankton hauls and fish trawling performed in areas of high anchovy density. Temperature, salinity and zooplankton biomass were stratified in the study areas, with cladocerans numerous above the thermocline whereas copepods were dominant below. Engraulis encrasicolus was strictly zooplanctivorous during the main spawning season with copepod and crustacean larvae dominating in stomach contents. Anchovy exhibited high trophic activity during the... |

Six kinds of crucifer (broccoli, cabbage, califlower, kale, mustard and rugula) were tested, as food, for larvae od Ascia monuste. The best results were obtained eith califlower, broccoli, rugula and kale. Four sugars (glucose, fructose, sucrose and maltose) were tested to know their influence on the number of oviposition in female of Ascia monuste. The best results were obtained with fructose, glucose and sucrose. |

This study, carried out from 1995 to 1997, within the framework of "Le Havre" harbour extension project, concerned halieutic populations and the characterization of a coastal nursery in the oriental part of the Seine bay and the Seine estuary . The main objective was to describe the specific and demographic composition of marine populations and their spatio-temporal distribution, and so assess the biological and halieutic role of this area. This study also included a research about the dietary needs of fish juveniles living in the estuary. Autumn and winter surveys results show that the estuary and area under direct influence are the richest from a biological and halieutic point of view. The mouth estuary isthe richest area in terms of diversity of... |

During larval rearing phase of turbot, a substantial variability in survival and growth is frequently observed. In this paper, we studied the effects of hydrodynamics in larvae rearing tanks on the survival and the growth of fed and starved larvae, using the following conditions: water flows of 600 and 1200 ml.mn(-1), constant and progressive ones, air flows of 10 and 30 ml.mn(-1), downward and upward water circulation, with direction change during the rearing phase. We also studied the interactions between water circulation direction and feeding conditions by (1) shifting the first feeding day (4 occasions, at 8 hours intervals, from 52 to 76 hours after 95% of hatching) and (2) using 2 amounts of preys (which differ by a factor 3). The results show that... |

Dans le cadre des études de physiologie, la fonction de filtration intervient dans le calcul du bilan énergétique, ou permet de déterminer la quantité d'aliment consommé par les mollusques filtreurs. Cette fonction peut également être considérée dans les relations avec le poids de l'animal, la température et un certain nombre d'indices de qualité et de quantité de l'aliment dont se nourrit le bivalve. Dans un contexte de coopération internationale entre scientifiques anglais, espagnols et français, une expérimentation physiologique sur les mollusques a été réalisée en septembre 1991 à l'IFREMER La Tremblade. De nombreux objectifs motivent cette expérimentation : la comparaison inter espèces, la confrontation des techniques mises en oeuvre par les... |
