Growth of Black Tiger Shrimp, Penaeus monodon, on Fishmeal Based Formulated Diet in a Southeastern Coastal Shrimp Farm of Bangladesh

摘要

Growth of black tiger shrimp, Penaeus monodon, was tested under field condition with four experimental diets having different protein percentages for a period of 120 days in a southeastern coastal shrimp farm. Four formulated diet with crude protein level of 30 to 45% were examined; eight ponds were used for the study, The experiment was designed on completely randomized design (CRD) with four treatments, each with two replications. Nursery reared juveniles of black tiger was used in the experiment. The water quality parameters such as temperature (28-28.75°C), pH (8.0-8.5), DO (5.21-5.65 ppm), alkalinity (152-155 ppm) etc., were found with in acceptable range of aquaculturc. The lowest food conversion ratio(|.60±0.20) was obtained under the dietary protein level of 40% (p< 0.05). On the other hand, reed with both 40% and 45% crude protein resulted in similar but significantly highest specific growth rate (SGR in 40% protein diet 25.77±0.55 and in 45% protein diet 25.33±0.41). Therefore, under the experimental condition, feed with 40% protein level may be recommended for culture of black tiger shrimp.
