Journal Title: International Journal of Biological Innovations - Year 2020, Vol 2, Issue 2
Abstract
Growth and survival of Pangasianodon hypophthalmus was assessed in relation to feeding of different feeds for a rearing period of 21 days. The experiment was designed with 3 treatments and 4 replications. The nursery ponds were stocked at a density of 0.6 million hatchling/ha with 3days old P. hypophthalmus. The highest growth performance, survival and production of the fry was found in treatment T in terms of length, weight and number, where sustainable nursery management was 1 implemented and egg yolk, mustard oil cake, nursery feed and Tubifex Chop were supplied. Poor growth performance and survival was recorded in treatment T where nursery management was poor 3, with insufficient food supply. The highest average growth was recorded at 5.66±0.55 g, SGR 12.24±0.68, FCR 0.68±0.01and survival rate 52.15±0.78% in the treatment T . The treatment (T ) 1 1 also showed highest economic return (Bd Tk. 290543/ ha) than that of treatment T and T . The 1 2 physico-chemical factors were found to be in optimum level for fish culture.
