摘要: Individual specimens of Euterpina acutifrons (Copepoda: Harpacticoida) taken from the mass cultures C.N.E.N.-EURATOM Laboratory at Fiascherino, Italy, were reared in new culture media prepared with suspensions several species algae filtered and sterilized sea water. All experiments carried out a temperature 18°C±1 C°. The influence food concentrations on adult life-span reproductive activity E. was analyzed. A good correlation found between concentration algal suspension egg production. Maximum observed intermediate values concentration. Other to determine fertility duration various embryonic postembryonic development stages. Embryonic time calculated as approximately 2 days; females appeared 10 12 days after hatching Nauplius I. Production nauplii by 6 under conditions excess supply also studied. These achieved supplying high mixture 4 different completely renewing medium frequent intervals. Under these conditions, each female laid an average 12.5 sacs produced 294.3 nauplii. An production 355.5 eggs per estimated. analysis made growth size weight females: daily terms dry corresponded about 32% biomass female. Birch's (1948) method used calculate net reproduction rate (Ro=70.89), intrinsic increase (rm=0.161) mean generation (T=26.5 days).
