Abstract :

Abstract[1] In this study, some biological parameters of Artemia parthnogenetica in the Incheh Lake, located in Golestan Province was studied in 2008. Biological characterization of the Artemia cists collected from Incheh Lake consists of the average length of naupli with 491.9 µ and the cyst length 268.8 µ, hatching percentage 35%, efficient hatch, 24600 and 90% maximum hatch was 20 hours. The physicochemical conditions for cultivation of Artemia in vitro followed by; water temperature, 27-29 °C, salinity 32 ppt, pH 7.5, dissolved oxygen (DO) 6.5-7 mg/l, naupli concentration 40 ind/l and the cultivation period 23 days. Artemia were fed by Chlorella with the cell concentration of 18×106 ind/ml. Total length, fecundity and survival rate were determined at the 23th days of experiment, maximum and minimum of length (TL) were 8.5 mm and 12.9 mm, total fecundity were 12 and 105, survival rate were 55 and 78 percent, respectively. However, genetic characteristics and feed quality are the important indices in fecundity ration of Artemia. * Corresponding Authors; Email: [e-mail]
