Title

IMPROVEMENTS IN THE DECAPSULATION TECHNIQUE OF ARTEMIA PARTHENOGENOTICA CYSTS FROM URMIA LAKE REGION

Pages

  42-47

Abstract

 As a result of its beneficial effects on the use of brine shrimp nauplii and decapsulated CYSTs in aquaculture hatcheries, the DECAPSULATION of artemia CYST is practiced more and more. Chemical DECAPSULATION of artemia CYSTs using HYPOCHLORITE is a widely applied technique in fish and crustacean hatcheries. Removing the chorion by means of a strong oxidant is believed to have beneficial effect on hatching and provide a complete disinfection of the CYST material. Furthermore it improves the separation of empty and non-hatched CYSTs from the Artemia nauplii after hatching. Standard DECAPSULATION procedure as described by Sorgeloos et al. (1977) is giving very good results for most of the commercial artemia strains. Some artemia strains sensible to this DECAPSULATION procedure and require a modified technique. With respect to structural (chorion thickness,) and genetical differences of artemia CYSTs improvement of standard procedure of DECAPSULATION for bisexual and parthenogenetica CYSTs of URMIA LAKE seems to be necessary. In this research with altering the percentage of active HYPOCHLORITE in DECAPSULATION solution as well as effective time, the optimum concentration and time for DECAPSULATION of parthenogenetica CYSTs of URMIA LAKE was measured. The treatments were 0.25%, 0.375% and 0.5% active HYPOCHLORITE with periods of 2, 3, 4 and 5 minutes. Variance analysis of data indicate that those have significantly differences and 0.5% concentration with period of 2 minute and 0.25% with 3 minute have high hatching percentage.
