The bulk of the world's fish meal and oil is today manufactured by the wet pressing method. The main steps of the process are cooking for coagulation of the protein thereby liberating bound water and oil, separation by pressing of the coagulate yielding a solid phase (press cake) containing 60-80% of the oil-free dry matter (protein, bones) and oil, and a liquid phase (press liquor) containing

In fish feed formulation we determine the types and proportion of ingredients to be mixed to produce a complete feed at possible low cost. The fish species in culture pond should be fed with a feed that imitates as far as possible the nutrient levels in their natural food. This is achieved to some

Feed formulation is the process of quantifying the amounts of feed ingredients that need to be combined to form a single uniform mixture (diet) that supplies all of the nutrient required by animal or allow to meet certain production objectives at a reasonable cost (preferably at the least cost)

5. A fish farmer while feeding the fish can study the behavior of fish and monitor their health. Generally in fish culture, the major factors affecting fish growth are stocking rate, stocking density, the water temperature, the quantity (adequacy) and quality of feeds, and the feeding method and frequency.

Apr 3, 2010 · The digestibility of a particular feed ingredient reflects the fish growth. The choice of dietary protein to be used in practical rations is an economic decision, which depends on the protein
