Aquatic feed

Extruded feed in aquaculture

Today, various methods are used to produce aquatic feed. Extrusion technology is currently the best way to produce aquatic feed for dense and ultra-dense systems. Extrusion is a process that is performed at high temperature and for a short time in which the raw materials are mixed in the condenser under cutting, pressure and temperature forces and finally removed from the extruded die. This feed is used in the aquaculture industry for different species of fish such as rainbow trout in four categories (beginning, growth, end, productive), common carp (beginning, growth, end, productive) and types of shrimp in three categories ( Initial, growth, end) is produced.

As a result of using extrusion feeds, it was found that due to the use of energy stored in lipids and carbohydrates and utilization of dietary protein amino acid reserves, the growth process of fish and shrimp is accelerated and nitrogen excretion by limiting oxidation Reduced amino acids, which have more benefits than pellet feed and increase production efficiency.

Seabass feed

The Asian seabass, known in Australia as Barramundi, is an opportunistic carnivorous game that has recently come to the attention of breeders in Iran and is mainly intended for cage farming.

In formulating seafood feed, the use of quality raw materials with high digestibility and considering the ratio of raw materials, the balance of amino acids and fatty acids is of particular importance. Therefore, Faradaneh Company, using the knowledge of fish nutritionists and based on the latest information in the world, as well as cooperation with breeding centers of this species in the south of the country, has started producing Asian oyster fish feed, which has resulted in producing quality feed with positive reports. Regarding its growth and proper conversion ratio, it has been followed by breeding centers.

This feed is produced using the most advanced extrusion system and is slowly submerged. The use of immune system stimulants to enrich feed, along with continuous monitoring of physical quality and feed digestibility in quality control tests, ensures the health of the fish and the prevention of contamination of farming environments.

Salmon feed

Rainbow trout extruded feed is produced using the latest formulated nutrition information and the latest extrusion technology. In the production of this feed from quality raw materials with high digestibility such as: various types of fish meal (kilka, sardines, moto and lantern fish), soybean meal, vegetable protein concentrates, wheat flour, wheat gluten, corn gluten, gelatin, oil Fish, vegetable oils, mineral and vitamin supplements, probiotics, prebiotics, immune stimulants, etc. are used.

The most important features of this feed are the following:

Have a regular shape, good buoyancy and immersion in water
Creates rapid and uniform growth in fish herds
Increase survival and reduce skeletal abnormalities
High digestibility and waste reduction
Improves the microbial flora of the gastrointestinal tract and increases the resistance of fish to disease and stress
Has a variety of products in feed sizes for different breeding systems (including conventional economic feed, special feed, pigment feed and immunoplas feed)
Creating a special formulation for the breeders’ feed in order to meet the nutritional needs of eggs and sperm in the sexual maturation process, increase breeders’ equity, improve egg quality and reduce larval stage losses, faster breeders’ recovery and preparation for the next spawning season

Ordinary carp feed

The extruded feed of common carp is formulated and produced in a way that meets all the nutritional needs of this fish at different ages. Ingredients of this feed are: animal and vegetable protein industries such as fish meal, soybean meal, rapeseed meal, vegetable protein concentrates, wheat gluten, corn gluten, gelatin, wheat flour, wheat bran, fish oil, vegetable oils, supplements Minerals and vitamins, growth stimulants and the immune system. Features that distinguish this feed are: • Complete feed and proper nutritional balance • Presence of all required minerals and vitamins • Proper profile of unsaturated fatty acids and essential amino acids, as well as appropriate amounts of protein and dietary energy • Increased Growth performance and reduction of proper feed conversion ratio • Optimal development of all body tissues including skeletal system • Improving the immune system and increasing resistance to stress and disease • Production in two forms, floating and sinking for proper use for various breeding systems (earthen pool, Concrete ponds, cages, in multicultural or monocotyledonous cultivation modes) • Various forage feeds with different protein and energy ratios for different breeding methods and different seasons (including type A, B and C feed)

Amur fish feed

Amur fish extruded feed (grass carp) provided by Khuzestan Aquatic Export Consortium is formulated in the best way and is produced in the form of floating lens-shaped pellets using advanced extruded technology. The prepared results show the optimal performance of the feed and increase the growth of amur fish, as well as increase the quality of meat and reduce the fat of the ventricular area. The use of some special and aromatic raw materials has made this dish very attractive for Amur fish and has increased appetite and reduced food conversion ratio.
