| For several reasons, the harvest stage is most important in aquaculture. Not properly managed, it may diminish efforts invested throughout the whole culture cycle. This operation consists in harvesting and in killing the fish for marketing purposes and must be achieved with care to optimizing the final quality of the product in terms of flavor, sanitary aspects and preparing it well for processing. Analysing the numerous complaints expressed by endusers concerning the quality of cultured salmon demonstates that the harvest stage is the main cause of these failures. Among the failures reported, we can quote the problems of "gaping" (disconnection of the myotomes in the fillets), of brown spots (spotlights of blood), of soft texture, discoloration and early... |

| The production of sea bass, a major species in Mediterranean fish farming, still relies in many cases on the production of fingerlings issued from wild breeders. Still, genetic improvement is a major key to sustainable development for all optimized forms of animal production. Three types of genetic improvement can be acheived in fish: i) the production of monosex populations. For seabass, monosex female populations would be the objective as females grow 20-30% faster than males. However, sex determination in this species is complex, impacted by both genetic and environmental factors. Hence, production of monosex populations is not yet a routine operation, although in some cases almost 100% female batches have been obtained; ii) chromosome set... |

| Movement activity and localization of food were studied dynamically with the objective of establishing the capacities of behavioral adaptation of the young Dicentrarchus labrax faced with a novel situation. The role played by previous rearing conditions was demonstrated, the level of stimulation being a sensitive intervening factor (currents associated with the food). The data show the favourable effects of such treatment, and are in agreement with work carried out on higher vertebrates, which have brought to light the importance of early stimulation in behavioral ontogeny which respect to emotionality as well as capacities of adaptation in subjects reaching adulthood. |

| The influence of dietary TAG source (fish oil, triolein, and coconut oil) and level (7.5 and 15% of the diet) on growth, lipase activity, and mRNA level was studied in sea bass larvae, from mouth opening until day 24 and from day 37 to 52. Fish oil and triolein induced better growth in both experiments, this being significant at a higher dietary level. Coconut oil significantly decreased growth at the higher level, possibly as the result of an excessive supply of medium-chain TAG. Growth was not related to lipase specific activity, suggesting a production in excess to dietary needs. Body lipid content was positively related to dietary lipid level and was affected by lipid quality. In addition, larval FA composition generally reflected that of the diet. The... |
