Efekti različitog saliniteta na sazrevanja kopepode acartia clausi iz Kaspijskog mora

The present study was conducted to evaluate the effects of salinity on maturation rate of Acartia clausi which is a copepod in Caspian Sea. The experiment was done during March to April 2007 and the referred zooplankton was collected from southern coast of Caspian Sea via plankton net. The gathered zooplankton was introduced to culture tanks for mass production. Afterwards Acartia clausi nauplius was isolated from tanks and transferred to four different salinities (07, 13, 18, 24psu) with three replicates in separate glass dishes in order to obtain growth and maturation. An equal mixture of Isochrasis galbana and Chaetoceros sp. alga were used for nauplii daily feeding. Statistic analysis indicated significant differences among the salinity treatments in the time of maturation (p
