The herring is one of the four major domestic fishes in China. It belongs to the order of Oystercatcheridae, Polygonidae, and Yarrowiae. It has a long shape and resembles grass carp. Its meat quality is the best in the four major fishes, and its price is the highest. Is a carnivorous fish, juveniles mainly ingest zooplankton, chironomid larvae and nauplii; stage of fish like screw, shellfish, small fish, shrimp and so on. Under artificial breeding conditions, we also like to eat a variety of compound feed.
1. Aquaculture environmental conditions 1 The pond is well-watered, with easy injection and drainage. The water source is of good quality and does not contain toxic substances.
2 The herring survival temperature is 0-40.5°C. The optimum growth temperature is 20-30°C. The PH value is 6-9. The optimum pH is 7-8.5, and the dissolved oxygen in water is not less than 3mg/L.
2, seed cultivation 1 pond area of ​​2-4 mu, water depth of 1.5-2 meters is appropriate for routine clear pond disinfection.
2 put the fish before the 3-5 days, 200-250 kg per manure manure fertilizer, fertilizing the water quality, so that there are palatable fish after the pond under the bait.
3 Shepherd herring Wuzi 5000-10000 tail, after temperature adjustment in the upper wind for stocking.
4 At the beginning of stocking, the main fertilizer and water were used to cultivate more small zooplankton for the consumption of herring. During the mid and late period, the herds were fed and fed. The herring had higher protein requirements than the conventional fish, and the protein content in the feed was not less than 30%. The fish meal was quite low. At 15%, after 10 days of domestication, most of the fish can feed on the fly. When acclimated, the feeding speed should not be too fast.
5 Regularly add new water and apply photosynthetic bacteria to keep the water fresh; regularly apply quicklime (20 kg/mu) to regulate water quality and prevent fish diseases.
3, adult fish cultured herring can be the main pond and polyculture with other fish.
During the main training, while feeding the artificial compound feed, at the same time regularly feeding some fresh snail meat into the pool to meet the nutritional needs of the herring and accelerating the growth of herring. Other feeding and management methods are the same as the seedling cultivation method. .
4, fish disease prevention and control of herring in the breeding process, the disease is particularly large, like the type of grass carp, susceptible to viral fish disease (hemorrhagic disease) and bacterial fish disease (enteritis disease, gill disease, red skin disease, white mouth disease White skin disease).
