Abstract
The invention discloses an overwintering feed for hybrid snakeheaded fish. The overwintering feed comprises the following components in parts by weight: 0.15-0.25 part of taurine, 0.01-0.02 part of an emulsifier, 2-3 parts of antarctic krill powder, 2-4 parts of beer yeast powder, 0.2-0.3 part of a yeast extract, 0.1-0.3 part of raw gingers, 0.05-0.1 part of garlic and 0.01-0.03 part of vitamin E. The fat content of the overwintering feed is higher than that of a common feed by 2-3 percent or so, and taurine and the emulsifier (glycerin fatty acid ester) are supplemented so as to improve the energy utilization efficiency of the hybrid snakeheaded fish; meanwhile, by matching of antarctic krill powder, beer yeast powder and the yeast extract, the intake rate is increased, so that slimming of fish bodies in an overwintering process and after overwintering is avoided.
Description
Technical field
The present invention relates to a kind of feed, more specifically, relate to a kind of overwintering feed and application thereof of hybridizing snakehead.
Background technology
Snakehead (Channa argus) and snakehead (Channa maculate) all belong to Perciformes (Perciformes), Anabantoidei (Anabantoidei), murrel section (Channidae), Ophiocephalus (Channa).The hybridization snakehead F1 generation that to be snakehead obtain by hybridization as female parent as male parent and snakehead.Hybridization snakehead is a kind of predacious fish of ferociousness, its growth rapidly, fine and tender taste, delicious flavour, nutritious, liked by consumer.
Snakehead is one of main cultured freshwater fish in Guangdong Province, particularly in recent years taking Shuande, the ground such as He Zhong mountain, the South Sea is the hybridization snakehead high-density breeding of representative, become and improve the high yielding culture pattern of water body utilization rate and specific yield and there is typical demonstration meaning.Approximately 200,000 tons of area, Pearl River Delta hybridization Snakeheaded fish feeding stuff capacity at present, approximately 160,000 tons of fish crops, by 10000 jin of fishes of every mu of average product, cultured area approximately reaches 30000 mu, supports family average mu profit in 10000-20000 unit left and right.Compare the cultivation of traditional aquatic products kind, the culture benefit of hybridization snakehead greatly improves, thereby its scale development is rapid in recent years.
But hybridization snakehead is easily morbidity at During Overwintering Period and after surviving the winter, and fish body generally reduces after surviving the winter, physique variation, easy infection promise Ka Shi bacteriosis, is embodied in rotten body like this; This susceptibility to disease and infectiousness are all stronger, once occur, fish body infection rate exceedes 60%, and raiser suffers heavy losses.Therefore, be necessary to develop a kind of hybridization snakehead overwintering feed, the fish body that this feed not only can avoid During Overwintering Period to cause reduces, also can improve its cold-resistant stress, thereby improve fish body physique and survival rate.
