Embodiment Construction

[0010] The working process of this example:

[0011] A herring culture method, comprising the following steps:

[0012] (1) Pond preparation: The pond area is preferably 4-6 mu. The pond requires a flat bottom and good water retention performance. The depth of the pond is 1.5-3m. Rich in nutrients, the transparency of the pool water should be kept at 30cm-50cm;

[0013] (2) Cultivation of seedlings: stocking density of 100,000-150,000 tails per mu, feed soybean cake milk on the 1st day to the 10th day after entering the pond, wherein 20 kg per mu for the first 5 days, and 30 kg per mu for the next 5 days , increase as appropriate after 10 days, 2 times a day, the whole pool is evenly sprinkled;

[0014] (3) Feeding and management: the feed requires consistent color, no peculiar smell, no mold, deterioration, and agglomeration. It is granular and has a high maturity. In the adult stage, the protein content should be between 25% and 35%, and a baiting platform extending three...

Abstract

The invention discloses a herring culture method, which includes the following steps: (1) pond preparation; (2) fingerling culture; (3) feed feeding; and (4) daily management. The fast-growing herringculture method has the advantages of fast growth, large number of eggs laid, high survival rate of young fishes and the like.

Description

technical field [0001] The invention relates to a herring breeding method. Background technique [0002] Herring is inactive and usually lives in the middle and lower layers of the water. Its food is mainly snails, mussels, clams, clams, etc. It also preys on shrimp and insect larvae. , in the fry stage, mainly feed on zooplankton. Herring grows rapidly and is relatively large. The largest adult fish can reach 70 kg. Herrings inhabit very low water layers and generally do not swim near the water surface. Most of them are concentrated in food-rich river bends and lakes along rivers for feeding and fattening, and overwinter in deep water. Strong action, not easy to catch. Oxygen consumption is close to that of grass carp. When the dissolved oxygen in water is lower than 1.6 mg / L, respiration is inhibited, and when it is as low as 0.6 mg / L, it begins to suffocate and die. It can survive in the water temperature range of 0.5-40°C. The optimum temperature for reproduction a...
