Compound feed for snakehead fish

Abstract

The invention discloses compound feed for snakehead fishes, aiming at providing compound feed for snakehead fishes having the advantages of low feed coefficient, balanced and comprehensive nutrition, strong palatability and high subaqueous stability. The invention is prepared from the following ingredients by weight percent: 20-29% of steam fish meal, 17-19% of direct firing fish meal, 21-26% of flour, 10.5-21% of soybean meal, 6-8% of peanut bran, 1-2% of imported liver powder, 0-1% of wheat gluten meal, 0.75-1% of soybean oil, 0.75-1% of phospholipid oil, 1.5-3% of fish oil, 0.8-1.2% of monocalcium phosphate, 0.8-1.2% of powdered zeolite and the balance of additives; and the additives contain complex vitamin, compound minerals, Vc organic phosphate, choline chloride, salt, mildew preventive and oxidation preventive. The compound feed for snakehead fishes can be widely applied to the field of snakehead fish aquaculture.

Description

technical field [0001] The invention relates to a compound feed, in particular to a raw fish compound feed. Background technique [0002] The raw fish belong to the class of Osteichthyes, Perciformes, Climbing Perciformes, Channaidae, and Channa. At present, the main species cultivated in our country are black snakehead, spotted snakehead and their hybrids, and raw fish is the common name of them. The local names of raw fish are: black fish, money fish, black stick, grouper fish, snake head fish, filial fish, silent head fish, etc. There are few bone spurs in raw fish, and the edible rate is 63%. In southern China, especially in Guangdong, Guangxi, Hong Kong and Macao, raw fish has always been regarded as a nourishing treasure for those recovering from illness and physically weak. In recent years, with the development of the domestic aquaculture industry and the needs of foreign trade, raw fish, which has the advantages of strong adaptability, rapid growth, and convenient...

Problems solved by technology

The traditional raw fish breeding method uses chilled miscellaneous fish to feed. This feeding method is costly and seriously damages the resource environment, which easily leads to deterioration of water quality. It is difficult to guarantee the normal operation of raw fish farming, and the feeding of chilled miscellaneous fish is easy to induce disease; more and more farmers are using feed feeding to raise raw fish, but the raw fish feed currently used is due to technical limitations. It is not perfect, and generally has problems such as poor food attraction, poor stability in water, and unbalanced nutrition, which lead to slow growth of raw fish, spit, weak disease resistance, and low survival rate, so it cannot meet the needs of raw fish farming.
