The Effect of Pond Soil Types and Stocking Weight of Mugil capito Fingerlings Reared in Poly-culture System on Production Performance
The present study is aimed to study the effects of pond soil types (sand and clay) and initial body weight of Mugil capito fingerlings on their growth performance, survival, production and profitability. It was used in the rearing poly-culture system of Nile tilapia (Oreochromis niloticus) with carp's species (common, silver and grass carps). Water quality results revealed that the T °C, salinity, pH ammonia and DO for SSP and CSP were in the appropriate limits Moreover, the water quality in CSP was better in quality and quantity of phytoplankton and zooplankton, were total numbers of phytoplankton community and zooplankton populations were higher in water samples collected from CSP stocked with M.capito SIW comparing with those collected from SSP, while the highest value recorded in CSP stocked with LIW. Fish performance parameters revealed that the final fish body weight, individual weight gain, average daily gain, specific growth rate, survival percentage and fish production were better in CSP than SSP. Moreover, results detected that the all growth parameter were the highest in CSP under stocking LIW of M.capito than SIW. The evaluation economic efficiency showed that CSP achieved the best revenue and the best growth and production performances. It can be concluded that, the all ponds are economically profitable and the revenue could cover the costs of production, but the LIW M.capito culture in CSP possessed the best economical profitability parameters than SIW fish culture in CSP and SSP.
