I. Renovation and transformation of fish ponds Before spring, the fish ponds should be diverted to deepen the ponds, ponds, and other water surfaces according to local conditions. The area should be appropriately expanded to more than 5 mu, and the perennial water depth should be kept above 2.5 meters.
Second, multi-species farming, polyculture and fish rearing are three-dimensional water use, to achieve more than 1 ton per mu, according to the situation in Guangdong, should be stocked more than 3,000 fish species. The upper layer of filter feeders and squid, which accounted for 90 and 120 fish respectively, was stocked three times a year; the middle carp (ie, grass carp) accounted for more than 1,000 fish, 0.5 kg, 0.25 kg and 50 g fish each accounted for 1/ 3, after 3 months of raising, the large grows to more than 1 kilogram, can be caught on the market, the implementation of catch-up small, uniform listing, but also can adjust the amount of fish contained in the pond; lower eel carp 1000, heterotrophic silver carp 200 or more high-backed unisexual tilapia, 500, as well as the bottom carnivorous raw fish (also known as mullet), Tanggu, California, 30 to 50 each. In this way, the upper, middle and lower ground fishes are gathered together in a pool and each has its own place, forming a product structure that promotes each other and uses each other, and exerts its best economic, technological, and ecological benefits.
Third, green, refined, fertilizer combination, clever feeding Guangdong has always used the big grass, large manure, peanut bran and other comprehensive feed fish feeding habits, the poultry, livestock, fish, fruits, vegetables closely together, so as to achieve low consumption, high yield Efficient purpose. In terms of feeding method, in a certain period of time, the main use of young grasses, stalks, peanut stalks, sugarcane leaves, elephant grass and other green feed to feed the squid, so that the excreted manure fertile pond water, culturing plankton, for fleas, The squid provides food; in the pond, raising three pigs, the manure is a good feed for omnivorous fish such as oysters, oysters, clams, and tilapia; a large amount of pond mud accumulating in the bottom of the pond is also a species of grain. The quality organic fertilizer. This can achieve the purpose of deep development, recycling, and multiple purposes. However, it is not enough to use only green material and feces to feed fish. It is also necessary to put some peanut bran, soybean cake or artificial compound feed within one month before the market.
Fourth, do a good job of fish disease prevention in a variety of farmed fish, the eel is the most susceptible to disease, there are common gill disease, red pimple, gastroenterology, hemorrhage, etc., is caused by viruses, bacteria and parasites Caused by. Prevention methods: First, aggravate the drugs before stocking and completely disinfect the ponds. Second, regular, quantitative, qualitative, and positioning feeds to promote fish health and enhance disease resistance; third, regular use of quicklime, copper sulfate, Bleaching powder, trichlorfon and other drugs disinfecting pond water, improving water quality and eliminating predators; Fourth, the hot water in summer and autumn is hot, change the water once every month, keep the water fresh, oxygen is sufficient to facilitate all kinds of fish fast Chang Yi Da.

Sweetener is a food additive that provides a sweet taste like that of sugar while containing significantly less food energy. Some sugar substitutes are natural and some are synthetic. It allows you to enjoy sweet tasting foods without the extra kilojoules from sugar. It can be beneficial for anyone trying to lose weight and control their sugar intake. Sweetener also does not contribute to tooth decay, as they are not broken down to acid by bacteria in dental plaque.
