Abstract

The invention discloses a net cage breeding method for puffer fishes. The method is characterized by comprising the following steps of 1, environment selection, wherein an area with a wide water surface, good water quality and sufficient sunlight is selected as a breeding base; 2, net cage preparation, wherein each cuboid net cage is 10 meters in length, 6 meters in width and 3 meters in depth; 3,breeding and stocking, wherein a dark glass water pool is used as a breeding pool at the early stage, the temperature is controlled at 20-25 DEG C, air is introduced into the water pool, the contentof dissolved oxygen in the water pool is greater than 5 mg / L, and 40-50 thousand fry are stocked into the water pool per cubic meter; 4, bait feeding, wherein bait fish flesh, small shrimp flesh and margarya melanoide flesh are used for feeding at the growth period; 5, breeding management, wherein duckweed and water hyacinths are planted in the net cages and cover 30% of the net cages on the watersurface. The net cage breeding method for the puffer fishes has the advantages that on the one hand, by breeding the puffer fishes in the net cages, water resources in rivers can be better utilized,and the management and operation are flexible; on the other hand, the puffer fishes do not easily get sick, the manufacturing cost of the net cages is low, and high profits can be obtained with the low cost.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a cage culture method for puffer fish. Background technique [0002] Puffer fish is a bottom fish in the warm temperate zone and tropical coastal waters. It lives in the middle and lower layers of the ocean. A few species enter freshwater rivers. The small thorns are erected for self-defense. Fugu is a delicious but highly poisonous fish. Contains protamine, collagen, taurine, selenium, zinc, and other trace elements, as well as EPA, DHA, etc., all of which have high nutritional value and health care functions. Puffer fish has the functions of dispelling cold and dehumidification, lowering blood pressure, etc. It also has certain effects on treating backache and leg pain and restoring essence. The toxin of puffer fish is effective in treating diseases such as dermatitis, whooping cough, asthma, tetanus spasms, stomach cramps, enuresis, and impotence. The toxin of puffer fish can al...
