Survey of production per area of Fenneropenaeus (Penaeus) merguiensis and F. indicus in Hormozgan province

Abstract

This project was conducted to survey production per hectare and other growth index of fenneropenaeus merguinsis and F. indicus in zar abzy fram in earthen ponds of Tiab area Hormozgan province. In this research for obtain aims used with two treatment and 3 replication. Postlarvaes were stocked at density 20 ind/m^2. Shrimp were fed by imported pellet on the basis of standard feeding table. In order to obtain the growth rate and calculation of daily feeding shrimp become biometry twice a month. Some of the physico chemical factor such and pH, dissolved oxygen and salinity were measured twice a month too. The results showed that mean weight of fenneropenaeus merguiensis were about 16.76 gr with mean daily growth 0.013 gr/day and for F. indicus obtain about 11.44 gr with mean daily growth 0.09 gr / day too. The results showed that mean F.C.R and survival rate in treatment 1 and 2 obtain 4.1 and 10 percent 1.7 and 64 percent respectively. The results showed that propagation of F.merguiensis is feasible and it can a culture species if suitable food is available.
