This year, the low temperature duration in Guangdong region has been relatively long. Tilapia fish ponds have been frozen to death due to the breeding of overwintering fish. Recently, a frozen reservoir of tilapia in the Huadu District of Guangzhou has lost more than 30,000 kilos of frostbite, and farmers have suffered heavy losses. This year, the low temperature duration in Guangdong region has been relatively long. Tilapia fish ponds have been frozen to death due to the breeding of overwintering fish. Recently, a frozen reservoir of tilapia in the Huadu District of Guangzhou has lost more than 30,000 kilos of frostbite, and farmers have suffered heavy losses. The reporter learned that tilapia is omnivorous, crude, fast, easy, and low cost, but the fish is tropical and subtropical. When the cold air is brought to the south, the water temperature drops to about 14°C. The risk of freezing and frostbite. Therefore, how to culture overwintering fish smoothly has always been a concern for many farmers. Yang Chunli, a farmer of tilapia farmers, cultivated over 20 hectares of wintering fish this year. In the absence of a greenhouse, 50,000 kg of tilapia passed winter. Li Bo told reporters that he is the second year of breeding winter fish, not to mention rich experience, he felt that this year tilapia can safely winter, mainly to do their own three key tasks. First, feed fish to fat spots before winter. Tilapia has a little fat and a little more fat. Tilapia's constitution will not decline during wintering, and its resistance will not decrease. Second, ensure that the water level is at least 2.5m. Increasing the water depth can increase the water temperature of the fish ponds, which is the most basic task for protecting the safety of farmed fish during the winter. Learned that wherever the depth of the water is more than 2.5 meters, where there are trees sheltering from the wind, it basically meets the requirements of heat preservation. Therefore, farmers must store foot pond water as early as possible so that the water depth can reach 2.5 meters. Li Bo introduced that there are also many people who have farmed over-wintering fish this year. Some of the water in the mouth of the pond is not enough, and there is still frost and frostbite. Third, in the event of rain or foggy weather, the aerator was continuously activated. Winter rain is generally more, but once it rains, the aerator still needs to continue to operate. In addition, many tilapia farmers have begun to provide equipment such as dissolved oxygen meters. As long as the dissolved oxygen level is below a certain level, the aerator can be started, which is also more convenient to operate. The reporter learned that there are many people who breed wintering fishes in Yangchun area, but few people build greenhouses. The main reason is that the cost of constructing greenhouses is higher than a year, plus the price changes of tilapia in the past two years. Breeding households are not at risk of raising overwintering fish. Li boss told reporters that after the autumn seedlings were put into use, the cultivation was relatively smooth. At present, the tilapia in Tangli is about half a catty. Although the current purchase price of tilapia is higher than last year, the overall specifications of tilapia still need to be Ascending, the fish body is also relatively thin, so after the spring begins, the temperature gradually rises, fattening up as soon as possible, if the price is good, even if it does not reach a pound can also consider listing.
