Aqua farming development on the world

[zenopelletmachine]

Fish farming is a local tradition for centuries on the world. More than half of total aquaculture production is seaweed while the rest is mainly finfish, shrimp, bivalves and other crops. The most important fish species cultured are milkfish, tilapia and black tiger shrimp.
Total aquaculture feed production consists mainly of milkfish, tilapia and shrimp feeds. Onset of diseases, fish kills due to bad culture practices, and the high cost of raw materials to produce high quality aqua feeds are the major problems that the entire fish farming industry must cope with.Aquaculture specifically requires high protein feed ingredients, such as fish meal and soybean oil meal, which have very little domestic production. Fish farmers are generally knowledgeable concerning the technical aspects of using commercial fish feeds as feed expenses account for more than half of their production cost.

The use of fish feeds on the world has grown substantially in the past few years, and now over 1 million tonnes of animal feeds are being formulated for use by fish farmers every year.The most popular fish feed is extrusion type which is processed by fish feed pellet machine .
Feeding of fish with formulated diets has contributed to increasing intensity of production of major fish species such as Nile tilapia, Pangas, climbing perch, major carps and others.
The fish farming industry must work towards ways and means of efficiently managing and utilizing local feedstuff resources, such as by improving processing methods, increasing digestibility and nutritional value, extending shelf life and freshness, and by developing formulations specific for each species, culture system, and culture environment.
Efficiency in feed utilization can also be better attained by ensuring hydro stability and by employing appropriate feeding methods and strategies.
