Croissance, production et demande d'énergie d'une population de soles (Solea vulgaris) introduite dans une lagune aménagée (bassin d'Arcachon) ArchiMer
Lasserre, G.; Lasserre, P..
Population of 4000 soles received from an induced spawing (COB-BREST), with a mean weight o£ 54 mg were introduced into a man modified lagoon (1000 m2 ) at Certes (4 soles/m2 ). The experiment was continued until December 1977 and permitted an analysis of the demographic evolution of the population : structure number, biomass, growth, production. Simultaneously an estimate of the trophic support necessary for the population derived by correlating oxydative demands with rate of oxygen consumption, was determined experimentally with specimens obtained during the samplings for growth and production (19 VII, 14 IX, 24 XI, 20 XII 1977). 1°) The demographic evolution of the population shows a rapid growth and a strong spread in size. For the short duration of...
