Fish Meal (66%) - Peru

Brief Overview

Any feed component that is high in nutrients and used in cow diets is referred to as "Fish Meal" (FM). Four to five tons of whole fish are needed to produce one ton of fishmeal, according to estimates. Since most fish are caught for their flesh and oil, the majority of them are regarded as industrial fish. Fishmeal has long been the primary source of protein in the aquafeed and agricultural sectors due to its high protein, high vitamin and mineral content, easily digested energy, and superior supply of essential fatty acids (EFAs).

Manufacturing Process

Because most fish used in commercial FM is tiny, oily, and bony, it is deemed unfit for direct human consumption. While there are more processes involved, extracting the water and oil from the solids is the fundamental process in making fishmeal.

1. Cooking

As the fish passes through a screw conveyor cylinder that is encased in a steam jacket, its tissue proteins coagulate.

2. Pressing  

Pressing is used to remove the liquid once the fish is fully cooked. Presscake is the term for the solid residue that is left over. On the other hand, after centrifugation, the fluid is processed again to separate the oil from the scattered particles and create fish oil. Customers can choose to purchase the "whole" meal or simply the "presscake" meal since the concentrated "stickwater" created during the liquor treatment process can optionally be reintroduced back into the presscake.

3. Drying  

Returning to the presscake, it is further dried, either directly or indirectly, until the moisture level is low enough to maintain its freshness for an extended period of time and inhibit the growth of mold and bacteria.

4. Grinding and packaging  

When fishmeal has dried sufficiently, it is processed and filtered to the appropriate particle size. This makes it possible to send it to several businesses all over the world in bags or to keep it in silos.

Animal Feed Industry

In addition to being a great source of calcium, phosphorus, and other minerals, fish meal is high in protein. Because of its high protein content and excellent amino acid balance for aquatic animals, it is very popular in aquaculture diets. It is also appropriate for cattle, hens, and pigs.

Fertilizer Industry

Fish meal naturally contains high levels of nitrogen, phosphorus, potassium, and other minerals required for plant development. Adding it to fertilizer mixes provides a balanced source of vital nutrients that support healthy plant growth and development.
