Wild Yangtze river coilia ectenes feeding habit forming artificial feed recipe and feeding habit forming method

Abstract

The invention discloses a wild Yangtze river coilia ectenes feeding habit forming artificial feed recipe, which comprises 40 to 45 percent of fish meal, 8 to 12 percent of starch, 1 to 2 percent of fish oil, 5 to 10 percent of dry earthworm powder, 2 to 4 percent of skim milk powder, 2 to 4 percent of dry fish organ powder, 3 to 6 percent of wheat strong gluten powder, 10 to 20 percent of shrimp meal, 1 to 3 percent of mixed inorganic salt, 2 to 5 percent of silkworm chrysalis meal, 3 to 6 percent of mixed mineral substances and 2 to 3 percent of various vitamins. A wild Yangtze river coilia ectenes feeding habit forming artificial feed feeding habit forming method comprises four steps of: feeding habit forming pool preparation, seedling specification selection, feeding habit forming feedrecipe and slow settling feed preparation and feeding habit forming processes. The feed has overall nutrition, the nutrition requirement of the coilia ectenes is met, and the survival rate and the growth rate of the fish are ensured. The operation of the feeding habit forming process is simple and convenient, the ecological feeding habit forming is emphasized, the wild Yangtze river coilia ectenes is successfully domesticated into the fish capable of adapting to artificial culture in a pool and realizing strong disease resistance and high growth speed, and the theoretical data and the practical experience are provided for the artificial domestication of other valuable carnivorous fishes with the same feeding habits and physiological conditions as the coilia ectenes.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a fish taming method, in particular to an artificial feed formula and a method for taming a rare migratory fish, wild anchovy species from the Yangtze River. Background technique [0002] Swordfish ( Coilia nasus ), belonging to Clupeiformes, Engraulidae, and Coilia, commonly known as saury. It is famous for its plump pancreas and tender and delicious meat. Migratory fish has broad development prospects for farming. [0003] Under natural conditions, cuttlefish have a wide range of feeding habits, both selective and random. They mainly feed on cladocerans and copepods, small fish, and shrimps of zooplankton in the water body. During artificial breeding, due to the fresh and live bait Supply is difficult, and large-scale intensive farming is limited, but feeding with artificial feed can solve this problem well, and effectively improve the survival rate of wild swordfish specie...
