Abstract

                                Good nutrition in animal production systems is essential to producea healthy, high-quality product economically. In fish farming, nutrition iscritical because feed represents 40-50% of the production costs. Fishnutrition has advanced dramatically in recent years with the developmentof new, balanced commercial diets that promote optimal fish growthand health. The development of new species-specific diet formulationssupports the aquaculture (fish farming) industry as it expands to satisfyincreasing demand for affordable, safe, and high-quality fish and seafoodproducts Conducted experiments on studies on fish feed formulation atCIPHET, Ludhiana. The present study evaluates the importance of fishfeed 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 ofthe feed ingredients ranged from 10 to 60 % and the crude fat contentswere 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 showedthat the minimum volume of pellets is 700.4 mm3 and maximum volumeis 925.504 mm3 and the minimum density of pellets is 0.00092 g. mm-3and the maximum density of pellets is 0.00107 g. mm-3 of the pellets. The0.5838g weight of the pellet will take less time to dissolve completely whencompared with more 0.9127g weight of the pellet.
