In a word, extruded fish feed can contribute to scientific feeding and management, saving much time and boost labor productivity. Recommended crumble/pellet sizes for trout of different age groups, 1 When moving to a larger feed size it is recommended that the two sizes are mixed together for 5 – 10 days, gradually reducing the amount of the smaller pellet until it is all gone, Table 8.

Other than that the puffing degree of floating fish feed can reach to 2 or even 3, sinking extruded fish feed is often less than 1.3. Province. mainland China and of agricultural related industries
By this token, extruded sinking feed is more suitable for river crab because it is easy to soften in water and fit for nibble with longer water resistance time and less crumb loss, decreasing feed waste and water contamination. 6 In the event that the vitamin premix specifications given in Table 3 cannot be produced, the trout vitamin premix produced by the Institute of Aquatic Products (Beijing) can be used. 7 Harvesting small wild fish to feed farmed fish can contribute to problems of overfishing, and can deprive wild carnivorous fish of their food sources. Production diets used for broodstock should have their vitamin levels increased by 50% to those employed in the fingerling diet

In addition to those benthonic animals, most aquaculture species can ingest floating extruded fish feed very well, not only for the famous-special fish species (like aquarium fish), but also for conventional cultivation (like grass crap, crucian, catfish, tilapia and so on). 6.1.5 Feeding method, 6.2.1 Project objective
