  1. 1.      Fish meal

Fish meal is a commercial product made from both whole fish and the bones and offal from processed fish. It is a brown powder or cake obtained by drying the fish or fish trimmings, often after cooking, and then grinding it. If it is a fatty fish, it is also pressed to extract most of the fish oil. Fishmeal is a nutrient-rich and high protein supplement feed ingredient that stores well, and is used primarily in diets for domestic animals and sometimes as a high-quality organic fertilizer.

We have earned a huge reputation as dried fish meal manufacturers and exporters. Due to its high protein content and superior quality, our fish meal is widely accepted by a large number of users. Protein content is depending on customer’s demands

            2.  Selecting  Species

Fishmeal is produced from different kinds of oceanic fish that are not eaten by people or its human consumption is limited. We are ready to supply 100% natural fishmeal produced from scad, tuna, sardine, herring. The leading fishmeal world producers’ plants are located in areas safe by ecological and biological characteristics.

Preserved by ice + salt. Preserved in a mixture of 5% ice + salt can be kept fresh for 16 days, 15% ice + salt mixture can be kept fresh for 30 days. Not preserved in a mixture of salt more than 15%, because the salt when preparing to conduct release long lost material makes many proteins, vitamins ... reduce the quality of fish meal. Equipment necessary for the production of fishmeal, including: water heaters, productivity 50kg/me; screw presses with hands 5kg/me; Centrifuge 16 kg / batch; Machines to 50 kg / batch; Machine dryer can be adjusted from 60 to 1200C, yield 100 kg / batch; crushing machine 100 kg / hour

Fishmeal is made by either cooking, pressing, drying and grinding of fish or fish waste to which no other matter has been added. It is a solid product from which most of the water is removed and some or all of the oil is removed. Four or five tones of fish are needed to manufacture one tonne of dry fish meal.

There are several ways of making fishmeal from raw fish; the simplest way is to let the fish dry out in the sun. This method is still used in some parts of the world where processing plants are not available, nevertheless the end product is poor in comparison with ones made by modern methods. Nowadays all industrial fish meal is made by the following processes

Cooking -A commercial cooker is a long steam jacketed cylinder through which the fish are moved by a screw conveyor. This is a critical stage in preparing the fishmeal, as incomplete cooking means that the liquor from the fish cannot be pressed out satisfactorily and overcooking makes the material too soft for pressing. No drying occurs in the cooking stage.

Pressing -A perforated tube with increasing pressure is used for this process. This stage involves removing some of the oil and water from the material and the solid is known as Press cake. The water content in pressing is reduced from 70% to about 50% and oil is reduced to 4%.

Drying- It is important to get this stage of the process right. If the meal is under-dried, moulds or bacteria may grow. If it is over-dried, scorching may occur and this reduces the nutritional value of the meal.

Grinding -This is the last step in processing which involves the breakdown of any lumps or particles of bone are involved in this stage.

4.Benefit

Fishmeal in diets increase feed efficiency and growth through better food palatability and enhances nutrient uptake, digestion and absorption. The balanced amino acid composition of fishmeal complements and provides synergistic effects with other animal and vegetable proteins in the diet to promote fast growth and reduce feeding costs.

High quality fishmeal provides a balanced amount of all essential amino aids, phospholipids and fatty acids required for optimum development, growth and reproduction especially of larvae and broodstock. The nutrients in fishmeal also aid in disease resistance by boosting and helping to maintain a healthy functional immune system. It also allows for formulation of nutrient-dense diets, which promote optimal growth. 

Incorporation of fishmeal into diets of aquatic animals helps to reduce pollution from the waste water effluent by providing greater nutrient digestibility. The incorporation of high-quality fishmeal into feed imparts a 'natural or wholesome' characteristic to the final product, such as that provided by wild fish.

Fishmeal is an enriched by protein ingredient for feeding. It is worldwide used:
1) 24% – in poultry breeding;
2) 29% – in pig breeding;
3) 35% – in fish-farming;
4) 3% – in ruminants breeding (especially in horned cattle and sheep breeding);
5) 9% – in other cattle breeding industries.

Fish meal is indispensable important component in animal feed and aquaculture.
