The temperature is very low. What should farmers do?

After the cold wave hit a few days ago, the temperature dropped a lot. The low temperature has the advantage of low temperature. Many of the work of aquaculture need to be done when the temperature is low, such as rectifying fish ponds. The Chinese Aquaculture Network specifically lists several things that should be done at low temperatures.

The entire modified fish pond: In December, the weather was cold, and the cold waves continued to invade. The temperature was mostly 0 to 5°C, which was a great opportunity for fish pond renovation and renovation. Combine dried fish ponds into the market, renovate and renovate the winter fish ponds, remove excess silt, and renovate the ponds, ponds and ponds.

Conventional fish species winter release: winter temperature, water temperature is low, fish activity is slow, easy to catch and transport, high survival rate of stocking; winter stocking can also extend the growth period of fish species, increase the size of commercial fish, and allow fish species to adapt to new farming earlier The environment creates conditions for early food and early growth in the coming year. Before the winter release, it is necessary to revise the mouth of the pond to meet the requirement of a large pool of water, thoroughly disinfect the pond, and cultivate water quality. Choose stocks with robust physique, neat specifications, no disease, no injuries, and strong vitality. According to the needs and changes of the aquatic product market, the main breeds should be selected and reasonably mixed with the polyculture species. After feeding, appropriate amounts of feed should be fed in a timely manner to ensure safe wintering.

Feeding and management: Macrobrachium rosenbergii broodstock is transferred to the greenhouse for cultivation, reasonable feeding, regulation of good water quality, promotion of gonadal development, timely mating and holding eggs. Pro-crabs should be moved into the indoor pool in a timely manner to feed, feed enough feed, promote mating and hold eggs, increase the surviving rate and the rate of holding eggs of the crabs. The conventional fish broodstock should be raised in a special pool. In early December, the intensive cultivation will increase the weight of the broodstock, increase the growth of the gonads, and promote the development of gonads to ensure smooth egg production next year. For the commercial fish, crabs and crabs listed on the New Year's Day, the Spring Festival and April to May of the following year, special pools should be raised, feeds should be fed on a regular basis to keep the water fresh, promote their preservation, ensure safe wintering, and ensure festival sales.
