WorldFish is an international, nonprofit research organization that harnesses the potential of fisheries and aquaculture to reduce hunger and poverty. Our publications database contains WorldFish publications and references to WorldFish research published in refereed journals and periodicals.
Aquaculture is critically important to food and nutrition security in Bangladesh. It provides 60 percent of animal protein requirements for Bangladeshis and makes up 3.65 percent of the country’s GDP . It has pulled more than 2 million of the 18 million Bangladeshis who came out from poverty. However, the sector is vulnerable and impacted by climate variability. High temperatures can affect fish growth and reproduction and erratic rainfall and fluctuation in temperature impact fish spawning.
Modern aquaculture requires the reduction of the feeds cost, which can partly be achieved by minimal use of dietary animal protein. Therefore, this experiment assessing the nutritional potential of using high protein distillers dried grains (HP-DDG) in formulation of affordable striped catfish, Pangasianodon hypophthalmus, diet for more sustainable development of aquaculture. Four diets containing 0, 25, 50 and 75% HP-DDG as partial replacement of fish meal were fed to P.
This study tested the effect of two diets differing in carbohydrate to lipid (CHO:LIP) ratio (4.7 vs. 19.5 g/g) on the contribution of natural food and the total fish production in tilapia ponds. Eight ponds, each divided into three equally sized compartments, were assigned to one of the two diets, which differed in CHO:LIP ratio but had the same digestible protein to digestible energy (DP:DE) ratio (15.5 and 15.6 g/MJ). Ponds were fed equal amounts of crude protein.
