Crab pool set up squid four attention
In recent years, many farmers have achieved better results through nesting of carp in crab ponds, but many farmers have followed suit blindly, resulting in failure. The author believes that the following points should be paid attention to if the crab pond is to raise its success. First, pay attention to crab pool conditions First crab pool should be strictly clear pond disinfection, especially in the previous year, the occurrence of heavier crab ponds, in addition to the normal use of lime, it is best to use pesticides once again. Secondly, there must be aquatic plants in the crab pool. The area covered by aquatic plants accounts for 30% to 50% of the total area of ​​the crab pool. There is no water grass to transplant some plants. Waterweed not only has a protective effect on river crabs, but also facilitates the carp to eat bait fish. Third, squid prefers fresh water bodies. Crab ponds should also be close to the water source. Water quality is good, and drainage should be convenient. Second, pay attention to carp species of stocking specifications and density According to the local cultivation situation, carp species specifications generally 5-7cm / tail is appropriate, the size is too small, especially the following 3cm carp species, under the pond, it is difficult to prey to The peculiar natural bait fish has low survival rate and is not listed at the end of the year; the specifications are too large and the cost is high, which has a certain influence on the growth of crabs. The amount of stocking depends on the amount of wild fish in the pond and the convenience of the source of the fish. Generally 10 to 20 acres of acre, no more than 30, no need to increase the bait fish. Crab ponds raise squid, and management is still based on crabs. Therefore, it is not appropriate to expand the amount of seeds to be put. For example, if more than 50 mou are to be placed, it is necessary not only to regularly supplement the bait fish, but also to take into account the palatability of the bait fish; More and more competition for eating crab feed, often more harm than good. Third, pay attention to anti-floating head carp low oxygen tolerance, dissolved oxygen requirements for water than crabs, at present, many crab pond stocking density is high, the general mu yield of 2000-3000, and some reached more than 5,000, easily in the late aquaculture , especially in summer and autumn caused the head of squid floating. Cause huge losses. Always change the water, maintain a high dissolved oxygen, conditional can be equipped with an aerator. Fourth, pay attention to disease prevention and medication adhere to the prevention, in addition to every 15-20 days per acre with lime 20-25kg Quanchiposa, the monthly use of trichloroisocyanuric acid or chlorine dioxide and other disinfectants per acre , with GuSO4, FeSO4. The mixture of 0.7ppm (5:2), used interchangeably, can effectively prevent crab and salmon diseases. When administering drugs to crabs, consider the sensitivity of salmon to drugs. If squids are more sensitive to crystal trichlorfon, they should not be used.
