Abstract

There is a need to develop diets for shrimp cultured in Egypt in different rearing systems that will provide sufficient protein for shrimp production while minimizing the amount of nitrogen being introduced into the culture medium. Bioflloc technology (BFT) as the new application in keeping up good water quality and growth performance of shrimp cultured. The present experiment was conducted to investigate the effects of three different stocking densities and the carbon source (sugarcane bagasse) with biofloc and control system (commercial diet 38% CP) in Litopeneaus vannamei on water quality. Shrimp were stocked with different densities in 18 tank at rate (12, 14 and16 larvae/L) with water volume 150 L for 90-days. Triplicate groups of shrimp (0.002g) were fed three time daily at a ratio of 14% from body weight and adjusted gradually to 5% at the end of the experiment. The water quality parameters (temperature, salinity, PH, total ammonia nitrogen (TAN), nitrites (NO2), nitrates (NO3), phosphate (PO4), total suspended solid (TSS) and biofloc volume (BFV)) were suitable for culture of L. vannamei in different stocking densities in biofloc and control treatments. TSS and BFV was significantly higher in biofloc treatments compared to control and especially in the third stocking density (16 BF Larvae/L). Addition of sugarcane bagasse as carbon source into L. vannamei culture can effectively increase the activities of nitrogen cycle bacteria, which can reduce inorganic nitrogen levels and gradual increase both TSS and BFV.
