Evaluation of growth performance of brown shrimp (Metapenaeus monoceros) fed with different commercial feeds in brackishwater pond

Abstract

In order to assess the production efficiency of brown shrimp, Metapenaeus monoceros, in brackish water ponds, a feeding experiment was conducted with three different commercial feeds: Quality feed, Saudi-Bangla feed, and Mega feed representing T1, T2 and T3, respectively. After 75 days of cultivation, T1 showed significantly (P<0.05) greater total production than T2 and T3. Survival of shrimp was 66.90% in T1 which was found highest than other two treatments (T2: 63.70% and T3: 62.95%). Net benefit was significantly (P<0.5) highest in T1 (723996 BDT/ha) than T2 (577823 BDT) and T3 (593386 BDT). FCR values in T1 (1.2±0.05) and T2 (1.2±0.02) were significantly (P<0.5) lower than T3 (1.3±0.01), but no significant difference existed between T1 and T2. Benefit-cost ratio (BCR) was 1.80, 1.52 and 1.74 in T1, T2 and T3, respectively. The current study demonstrates that the monoculture of M. monoceros fed with commercial feed (Quality feed) with 45/m2 stocking density would be commercially viable in Bangladesh coast.
