High-temperature-stage feed for hybrid snakeheads and application thereof

Abstract

The invention discloses a high-temperature-stage feed for hybrid snakeheads, which comprises the following components: fish meal, chicken meal, meat and bone meal, shrimp meal, spray-dried blood cellmeal, soybean protein concentrate, corn protein meal, peeled soybean meal, beer yeast powder, flour, vital gluten, fish oil, phospholipid oil, L-lysine hydrochloride, DL-methionine, L-threonine, a yeast extract, monocalcium phosphate, a vitamin mixture, a mineral mixture, choline chloride, taurine, squid visceral ointmen, emodin, vitamin C, vitamin E, edible salt, an antioxidant and a mildew preventive. The invention further discloses an application of the feed in the high-temperature breeding period of the hybrid snakeheads. The feed provided by the invention has high protein content and goodpalatability, can improve the high-temperature stress resistance of the hybrid snakehead, can reduce the damage to the liver of the snakehead body, can enhance the physique of the snakehead body, andcan improve the survival rate of breeding.

Description

technical field [0001] The invention relates to the field of aquatic fish feed, in particular to a hybrid snakehead high-temperature period feed and application thereof. Background technique [0002] Channa argus and Channa maculate both belong to the order Perciformes, the suborder Anabantoidei, the family Channidae, and the genus Channa. The hybrid snakehead is the F1 generation obtained by crossing the snakehead as the male parent and the snakehead as the female parent. Hybrid snakehead is a ferocious carnivorous fish. It grows rapidly, has tender meat, delicious taste and rich nutrition, and is deeply loved by consumers. [0003] Snakehead is one of the main freshwater cultured fish in Guangdong Province. In recent years, the high-density breeding model of hybrid snakehead represented by Shunde, Nanhai and Zhongshan has become a model model for high-yield farming to improve water utilization and unit output. At present, the feed capacity of hybrid snakeheads in the Pea...

Problems solved by technology

[0004] However, the summer in the Pearl River Delta region is extremely hot and lasts for a long time, there is a lot of rain, and the water quality fluctuates greatly, causing a continuous stress response to the fish body. The hybrid snakehead is prone to outbreaks of diseases during this period, mainly Nocardia bacterial disease. It is manifested as rotten body; this disease is highly contagious and contagious, once it occurs, the infection rate of fish body exceeds 60%, which will cause heavy losses to farmers
