A feeding trial was conducted to evaluate the effect of mixed feeding schedule on the growth and production of sutchi catfish (Pangasius hypophthalmus Pangasiidae) in experimental ponds (30 m2 ) for 70 days. Six feeding regimes employed were: continuous normal feeding (T1) alternate day feeding (T2) alternating 3 days normal feeding (NF) and 4 days restricted feeding (RF) (T3) alternating 7 days NF and 7 days RF (T4) alternating 14 days NF and 14 days RF (T5) and alternating 28 days NF and 28 days RF (T6). The restricted feeding was 1 of fish body weight. Results showed that the mean weight gain of fish was significantly (P 0.05) higher productions (kg ha-) were observed in T1 and T4. The highest profit was obtained in T4 due to compensatory growth and saving of feed cost. The results of the present study demonstrated that a mixed feeding schedule of alternating periods of 7 days normal feeding followed by 7 days of restricted feeding is more profitable for sutchi catfish farming than continuous normal feeding.

Abstract

A feeding trial was conducted to evaluate the effect of mixed feeding schedule on the growth and production of sutchi catfish (Pangasius hypophthalmus Pangasiidae) in experimental ponds (30 m2 ) for 70 days. Six feeding regimes employed were: continuous normal feeding (T1) alternate day feeding (T2) alternating 3 days normal feeding (NF) and 4 days restricted feeding (RF) (T3) alternating 7 days NF and 7 days RF (T4) alternating 14 days NF and 14 days RF (T5) and alternating 28 days NF and 28 days RF (T6). The restricted feeding was 1 of fish body weight. Results showed that the mean weight gain of fish was significantly (P 0.05) higher productions (kg ha-) were observed in T1 and T4. The highest profit was obtained in T4 due to compensatory growth and saving of feed cost. The results of the present study demonstrated that a mixed feeding schedule of alternating periods of 7 days normal feeding followed by 7 days of restricted feeding is more profitable for sutchi catfish farming than continuous normal feeding.
