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.
