| 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... |

| Coordinated ECOTRON Program on the Arcachon Basin (Aquitaine, France) : Control of marine biological production in a man-modified lagoon ecosystem (fish ponds). Results, synthesis and prospects. The "fish reservoirs" of the Arcachon Basin consist of eutrophic lagoon ecosystems, empirically exploited for extensive amphihaline fish culture (grey mullets, sea bass, eels, sea breams). The 1000 hectares of exploited farms, well integrated in a traditional socio-economic context, are presently not adapted for various reasons.The coordinate researches, which have been developed at Arcachon since 1974, within the ECOTRON (CNEXO) Program, show that these highly productive man modified ecosystems are well adapted for the development of semi-intensive aquaculture.... |
