An experiment was conducted to determine the effect of two commercial feeding types: Shrimp feed 38%CP (SF38) and Tilapia feed 36%CP (TF36) on the growth performance of white shrimp (Litopenaeus vannamei) . Twelve cage nets (2 x 1.5 x 1 m), each 3 m3 and 10 m2 were stocked with juvenile shrimp (average weight , 1.65 ±0.85 g) at a density of 20 shrimp/m2 . Shrimp in six cage s were fed with SF38 and six others with TF36. Selected water quality parameters were monitored over a 105-days period. Shrimp growth, survival, feed conversion ratio (FCR) and water quality parameters were evaluated at day 105 harvest. No significant differences were found between the SF38 and TF36 treatments in the daily-measured water quality parameters (dissolved oxygen, temperature, pH, Secchi readings, and salinity) and the weekly-measured p arameters (total ammonia-N and nitrite-N). Cultured shrimp fed by SF38 showed greater mean weight (18.0 ± 2.6 g) and yield than those fed by TF36 (14.4 ± 3.6g). Feed added at libit um reaching an average per cage 3564 gm in TF36 and 3860 gm in TF36 during the experiment period 105-days. The s hrimp survival was not significantly different between the two treatments 71 percent in SF38 and 67 percent in TF36 . The FCR of the shrimp in the SF38 treatment (1: 1.4) was significantly lower (P <0.001) than in the TF36 treatment (1: 2.0 ). The growth rate was defined for 1.1 gm/week in SF38 and 0.85 gm/week in TF36. This work shows that the SF38 diet provided better production results (25.6 gm/m2) 33% higher than the TF36 diet (19.3 gm/m2), yet it did not significantly deteriorate the water quality. The result of the study implied that SF38 more suitable and economically viable than that TF36 treatment for shrimp farming.
