Studies on fish feed formulation

Good nutrition in animal production systems is essential to produce a healthy, high-quality product economically. In fish farming, nutrition is critical because feed represents 40–50% of the production costs. Fish nutrition has advanced dramatically in recent years with the development of new, balanced commercial diets that promote optimal fish growth and health. The development of new species-specific diet formulations supports the aquaculture (fish farming) industry as it expands to satisfy increasing demand for affordable, safe, and high-quality fish and seafood products Conducted experiments on studies on fish feed formulation at CIPHET, Ludhiana. The present study evaluates the importance of fish feed pellets as alternative feed ingredients for fish feed preparation. Commonly available materials i.e., debittered mustard oil cake, fish meal, maize powder, and mineral powder mixture. The crude protein content of the feed ingredients ranged from 10 to 60 % and the crude fat contents were recorded as 4 to 12%. Crude fiber contents were between 1 and 8 % and ash contents ranged from 6.9 to 38 %. In this study, results showed that the minimum volume of pellets is 700.4 mm³ and maximum volume is 925.504 mm³ and the minimum density of pellets is 0.00092 g. mm^-3 and the maximum density of pellets is 0.00107 g. mm^-3 of the pellets. The 0.5838g weight of the pellet will take less time to dissolve completely when compared with more 0.9127g weight of the pellet.
