It is suitable and efficient for squid

Each year, the harvest of Macrobrachium rosenbergii is listed until the second year of spring. The shrimp pond has more than 6 months of free time. During this period, the squid is raised with rice, the seeds are loose, the feed is rich, and the squid raised to the next year 4-5. Monthly listing, the price is relatively high, greatly increase the pond output rate, directly increase the breeding efficiency. Its main stocking technology:

In the second half of October, dry ponds were used to harvest Macrobrachium rosenbergii. After the clear ponds were cleaned with lime, fish species were stocked for 10 days. The specifications were 150 to 200 grams per tail, and 300 were released per acre. The fingerling is disinfected with salt solution in front of the pond.

In early November, squid was planted with feed fish at the same time. Starting from 25-50 grams per mu of surface water, 150 kg of carp, carp fingerlings and loach will be weighed, and 100 silver carp tails weighing 400-450 grams will be stocked. Feeding is carried out according to stages. Before March, the following year, the sunny days are fed once a week. In March, the feed is fed twice a week. Each time, the amount of feed fish is 15-20 kg per acre. According to the weather conditions, it is increased in April. Ensure that the ratio of squid and feed fish tails is 1:5 to lO. The density of feedstuff fish is too thin, and squid will affect the growth due to excessive consumption of predatory feed fish; the density of feedstuff fish is too high and it can easily cause anoxic floating heads. In order to ensure the growth of feed fish, appropriate amount of rapeseed cake should be put in at the same time. Points to note: feed fish should be rich in palatability, and the total supply of feed fish should be at least 4 times the weight of commercial carp. Feed fish need medicinal bath after the pond.

Catfish species require regular specifications, no disease and no injury; stocking capacity should not be too large, stocking specifications can not be too small to improve the listing rate. 5 grams per cubic meter of water in the first five days before the next pond is sprayed with 0.5 grams of B type extermination to kill the head of the head; every month, every cubic meter of water with a strong insect killer 0.25 gram of water and water Times. The water body requires rich dissolved oxygen and fresh water. Every 15 to 20 days in winter, add new water once, each time adding 10 to 15 centimeters of water; add water once every 7 to 10 days in spring and add 20 to 30 centimeters of water each time. Keep the dissolved oxygen content of the water body above 4 mg/l, and keep the transparency more than 40 cm.

From the end of April to the beginning of May in the pond, the squid has about 150 kilograms of squid per mu, and the net profit per mu is more than 2,000 yuan.
