What to pay attention to when stocking fish fry in reservoirs in winter
Every winter is the golden season for stocking fish species such as silver carp, bighead carp, grass carp, and black carp into reservoirs. But quite a few fish farmers report that within 2 to 7 days after stocking the fry, large numbers of dead fish and swimming sick fish appear on the surface of the reservoir water; these fish lose their luster and their body surface mucus increases. Based on the above symptoms, it can be inferred that the fish have contracted a typical case of "acclimation sickness." This disease is mainly caused by a drastic change in water temperature, in which the nerve endings in the fish skin are strongly stimulated, causing dysfunction of the internal organs, and its death

Precautions for Spring Transport and Stocking of Fish Fry
Spring returns to the earth, water temperatures gradually rise, and it is once again the best time of year for transporting aquatic fry and fingerlings. During this period, because water temperatures are relatively low, fish are less active, and at the same time their bodies are firm and scales tight, so they are less likely to be injured during transport, which can increase the survival rate of spring stocking of fingerlings. There are many precautions in the spring transport and spring stocking of fingerlings, and fishermen friends are reminded to pay attention to them. 1. Pond disinfection should be carried out after removing excess sludge from the pond, reinforcing the pond embankment, and clearing the inlet and drainage ditches. Generally, for a dry pond, use about 200kg of quicklime per mu, slake it into a slurry, and

What are the pond-clearing methods? Remember these five before stocking fish fry
Before stocking fish fry, the aquaculture pond must be cleared to kill various predatory small wild trash fish, harmful aquatic animals and plants, parasite eggs, pathogenic bacteria, etc., creating a good environment for the growth of adult fish. The following five pond-clearing methods are introduced: 1. Clearing the pond with quicklime. When carrying out drainage pond clearing (that is, draining the pond water to a depth of 5-10 cm of remaining water before clearing), use 60-70 kg of quicklime per mu of pond; when clearing without draining, use 125-150 kg per mu of pond for every meter of water depth (200 ppm).

Key Technical Measures for Stocking Fish Fry in Winter
As the saying goes, "Stock fish fry in spring and they catch disease; stock fish fry in winter and they grow three fen." Practice has proven that the period from the Winter Solstice to the Start of Spring is the best time to stock fish fry. There are three reasons: first, the fry are plump and firm-scaled at this time, with strong adaptability. Second, the low water temperature weakens the fish's activity, resulting in a high survival rate during catching and stocking. Third, it avoids the trouble of merging ponds for overwintering, allowing the fry to be dispersed and intensively reared earlier, promoting early spring growth. 1. Pond renovation. Use the idle winter season to renovate fish ponds: turn small ponds into large ones, stagnant ponds into aerated ones, and shallow ponds
