Putian fish farming technology
Build fish ditch nests. Fish ditch fish nests are the activities and habitats of fish. The area requirement accounts for more than 10% of the total area of ​​Putian, and it is better to reach 15%. The fish ditch is 1 meter deep, the fish nest is 2 meters wide and 1.5 meters deep. The ditch and nest must be connected. Conditional use can be made of grass mud ponds and water intakes at the head of the field to process permanent ditch nests. Improve stocking structure. At the later stage of production in Putian, most of the water surface is covered by lotus leaves, and the amount of dissolved oxygen is generally lower than that of ponds, and plankton is also less, while zoobenthos, aquatic weeds and insects are more. The stocks that are stocked in Putian should be based on fish that are resistant to hypoxia and food, such as oysters, clams, oysters, clams, herring, tilapia, and squid. You can also stock a small amount of quail and squid. It is necessary to strictly control the number, size and time of grass carp feeding so as not to affect the growth of lotus roots. Rational fertilization. The fertilization in Putian is mainly based on urea and ammonium bicarbonate, and is carried out in front of the lotus leaves to grow water. Each acre uses 25-50 kilograms. In order to prevent the impact of fertilization on fish, half-side and half-side treatments can be used. A variety of farming methods. Such as "Yu-ping fish type", "fish rotation", "squid and fish" and other methods. “Yanping fish type†is a kind of duckweed that breeds quail in shallow water, raises fish in deep water, and raises fish on the water surface— duckweed. Putian provided abundant biological feed and a good habitat for fish. Fish manure was a good fertilizer for Putian, and it played a good role in recycling. Strengthen management. Always check fishing equipment to prevent fish escape. Do a good job in sanitation work and remove the remaining slag baits promptly. Inject new water regularly to maintain a certain level of water in the ditch nest. Fertilizer should take into account the fish and fish. In addition, we must regularly sprinkle bleaching liquid, regularly feeding garlic, leeks, furazolidone and other baits.
