Elevage du bar américain Roccus Saxatilis (Walbaum, 1792) - I. Méthodes utilisées

Willing to acquire the fish culture techniques necessary to tackle the issues raised by marine fish culture, we undertook training in the U.S.A. and chose as our research subject the American Striped Bass (Roccus saxatilis WALB, 1972) whose semi-intensive culture is booming (l). To start with, we will recall some biological data. It is a Perciforme belonging to the Serranidae family, abounding on the Atlantic coast of the United-States. It is found all the way from Canada to the North of Florida, which shows a great eurythermy. Moreover, it is an extremely euryhalin fish: it lives either in the ocean, along the coasts, or in brackish waters, in bays and estuaries, and can swim upstream to areas where salinity is almost null. Adult individuals of the same age and of different ages are found in the ocean and in brackish waters; thus, it is impossible to link some specific growth stages to preferred salinities. [...]
