Powders will all have a residual moisture content in the 4-8% range. Fish protein concentrate (FPC) - is a powder concentrate with medium level of protein (50-70%) and will contain some level of fat/oil (1-20%) in the powder form as well. [7] Fish protein isolate (FPi) - where the product contains less than 1% fat/oil and more than 90% protein.
Prior to 1910, fish meal was primarily used as fertilizer, at least in the UK. [2]Fish meal is now primarily used as a protein supplement in compound feed. [2] [3] As of 2010, about 56% of fish meal was used to feed farmed fish, about 20% was used in pig feed, about 12% in poultry feed, and about 12% in other uses, which included fertilizer. [1]
If fish hydrolysate is heated, the oils and certain proteins can be more easily removed to be sold in purified forms. The complex protein, carbohydrate and fats in the fish material are denatured, which means they are broken down into less complex foods. Overheating can result in destruction of the material as a food to grow beneficial organisms.
Whey protein: This protein powder, derived from milk, is “best for muscle building and quick recovery due to its rapid absorption and complete amino acid profile,” says Durham. However, it’s ...
The feed consists of protein-rich defatted biomass of Nannochloropsis oculata and whole cells of DHA-rich Schizochytrium sp. and was found to perform better in growth, weight gain, specific growth rate, best feed conversion ratio and fish nutrient content than the reference diet of ocean-derived fishmeal and fish oil.

Fish meal is made from both whole fish and the bones and offal from processed fish. It is a brown powder or cake obtained by rendering pressing the whole fish or fish trimmings to remove the fish oil. It used as a high-protein supplement in aquaculture feed. Fish sauce is a condiment that is derived from fish that have been allowed to ferment ...
Rendering can be carried out on an industrial, farm, or kitchen scale. It can also be applied to non-animal products that are rendered down to pulp. The rendering process simultaneously dries the material and separates the fat from the bone and protein, yielding a fat commodity and a protein meal.
Fish emulsion is a fertilizer emulsion that is produced from the fluid remains of fish processed for fish oil and fish meal. Fish derived protein hydrolysates have been identified to exhibit a wide range of bioactivities making them important to food and health care industries. [ 13 ]
