Abstract

The invention provides a snakehead larva fish feed. The snakehead larva fish feed is composed, by mass of dried matters, of 30-34 parts of fish meal, 2-4 parts of hydrolyzed fish protein powder, 5-8 parts of pork powder, 3-7 parts of spray-dried serum globulin powder, 3.5-7 parts of shrimp meal, 4-8 parts of krill meal, 9-11 parts of fermented soybean meal, 13-17 parts of flour, 4-8 parts of tapioca, 1.5-2 parts of fish oil, 1.5-2 parts of soybean oil, 1.5-2 parts of soybean lecithin oil, 1.5-2 parts of calcium dihydrogen phosphate, 1 part of Chinese herbal medicine compound preparation and 2 parts of premix additive, wherein the Chinese herbal medicine compound preparation consists of the substances of, in parts by weight, 12 parts of honeysuckle, 10 parts of safflower, 10 parts of tuckahoe, 8 parts of tuber onion seed, 6 parts of polygala tenuifolia, 4 parts of dodder and 50 parts of rice husk powder. The snakehead larva fish feed can enhance the immunity of snakehead, prevent the infection of visceral sarcoidosis, have good therapeutic efficacy on snakehead suffering from visceral sarcoidosis and improve the survival rate of snakehead in aquaculture.

Description

technical field [0001] The invention relates to the field of feed, more specifically, to a feed for juvenile raw fish and its application.

Problems solved by technology

With the development of artificial high-density breeding, various diseases of raw fish frequently occur, such as saprolegniasis, rotting skin disease, ascites disease, gill rot disease, etc., especially in recent years, the body surface ulcers and visceral white nodules are the main ones. Symptomatic sarcoidosis, the disease lasts for a long time and the etiology is not yet clear, which causes great difficulties in prevention and treatment, and causes serious harm to raw fish farming
