Definition: How is Fish Meal Made?

Fish meal is a valuable agricultural product that is produced through a process known as fish meal production. It is a high-protein feed ingredient that is commonly used in animal nutrition, particularly in aquaculture and livestock industries.

1. Raw Material Selection

The first step in fish meal production is the careful selection of raw materials. The most commonly used raw materials for fish meal production are small, oily fish such as anchovies, sardines, and herring. These fish are rich in protein and have a high oil content, making them ideal for fish meal production.

2. Fish Processing

Once the raw materials are selected, they undergo a series of processing steps. The fish are first cleaned and then cooked to remove any bacteria or parasites. The cooked fish are then pressed to separate the liquid, known as fish press liquor, from the solid material.

3. Drying and Grinding

The solid material obtained from the fish processing step is then dried to reduce its moisture content. This is typically done using a combination of heat and air. Once dried, the material is ground into a fine powder using specialized equipment such as hammer mills or disc mills.

4. Oil Extraction

In addition to fish meal, fish oil is also extracted during the fish meal production process. The fish press liquor obtained earlier is subjected to a centrifugation process to separate the oil from the water. The extracted fish oil is then further processed and used in various applications, including the production of omega-3 supplements.

5. Quality Control

Throughout the fish meal production process, strict quality control measures are implemented to ensure the final product meets the required standards. This includes regular testing for protein content, moisture levels, and absence of contaminants such as heavy metals or toxins.

6. Packaging and Storage

Once the fish meal is produced and passes the quality control tests, it is packaged into bags or bulk containers for distribution. Proper storage conditions, such as cool and dry environments, are essential to maintain the quality and shelf life of the fish meal.
