| The main objective of this study is the valorisation of by-products coming from processed tuna (Thunnus albacares). Therefore, enzymatic hydrolysis was selected, using an industrial large spectrum protease (Protamex). In a first phase, hydrolyses of these by-products (heads, tails, viscera) were carried out for long periods of time (12h) in order to establish the kinetics of the proteolysis of those different by-products and to obtain the approximate composition of the different resulting fractions and to determine the conditions which would allow the valorisation of these fractions. In a second phase the valorisation in animal nutrition (shrimp culture) and in human nutrition (fish sauce) of the fractions coming from the hydrolysis of the head of tunas... |

| 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... |

| Industrial potentialities related to biotechnology of microalgae are examined, highlighting a wide spectrum of applications which concern principally nutrition, health, environment and energy. The french situation of research on microalgae, especially at Ifremer, is assessed, showing that the main axis are fine chemistry, aquaculture, environment, bio-process engineering. It covers the majority of the applications, but leaves in shade certain important aspects such as human food and CO2 fixation. Concerning the general approach, some significant improvements can be expected from a more accurate control of bacteriological and genetic quality of cultures. About the industrial aspects, a national initiative seems in progress. The variety of potential... |

| 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... |

| 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... |

| The GERMON project had several aims i) to understand the populations’ structure between albacore tuna southwest of the Indian Ocean and southeast Atlantic, ii) to determine the origin of juveniles observed in South Africa iii) to improve the understanding of the biology field (Size/Size and Size/Weight; reproduction and feeding area; trophic linkages) and iv) to initiate work on chemical analyzes and adaptation of the albacore species to its environment. These aims have been held and the results allow a better understanding of the management albacore. A general summary of results is presented in Part 9. |
