Study on breeding of imported brood stocks Litopenaeus vannamei in Iran environment

Abstract

Regarding to breeding the Litopenaeus vannamei, a total of 126 pairs of broodstocks were imported from Hawaii to Iran in 2004 and 2005 , and then transferred to the Bandargah Research Station in Bushehr. The female broodstocks were ablated, and were feeded 3 times per day with cuttlefish ,small size shrimp and Nereis worm with a ratio of 30% body weight .The water exchange were done 3 times per day. During the years 2004 and 2005 a total 1700000 naupli were produced of which 772000 specimens of pl13 and pl7 were harvested and then transferred to Helleh Site for carrying out the next culture project. The average naupli and postlarvae were 170000 and 92000 in proportion to each broodstock. Also the mean survival rate was estimated 54%.
