Última Elevage de copépodes calanoïdes. Biologie et dynamique des populations : premiers résultats ArchiMer Person-le Ruyet, Jeannine. Four species of planktonic Calanoid Copepods, Acartia clausi, Centropages typicus, C. hamatus and Temora longicornis, were cultured during one year, at 20°, with the green algae Tetraselmis suecica. The generation time and reproductive rate are investigated, the best results are obtaincd with C. hamatus and A. clausi : 50 and 60 adults per female, and per cycle (20 and 21 days).

Long-term effects of constant exogenous ammonia concentrations were investigated in two different batches of turbot juveniles (53 and 73 g) under controlled environmental and feeding conditions. Over the 84-day experiments, ambient un-ionized ammonia (UIA-N, NH3) concentrations were steady (coefficient of variation, 12-16 %) and water pH range was 7.88-7.99. Survival was maximum up to 0.33 mg.l(-1) UIA-N and at 0.73, 50 % mortalities were observed on day 52 (73 g) or day 77 (53 g). No-growth concentration was 0.73 mg.l(-1) UIA-N in the two groups and the 84-day lowest-observable-effect concentration range 0.14-0.33 mg.l(-1). In the most tolerant group (53 g), the 84-day no-observable-effect concentration was 0.14 mg.l(-1) UIA-N. The estimated 28-day...
