Embodiment 1

[0018] (1) Take a 10 mu pond as an example. Pond area 10×667m 2 , the drainage is convenient, the slope ratio of the pool is 1:3, asbestos tiles are used around the pool to build a 0.7-meter high-defense facility, and quicklime 100-150kg / 667m is used in December every year 2 Clear pond disinfection is equipped with a set of 2.2 kilowatt microporous aeration and oxygenation machines.

[0019] (2) Plant aquatic plants in the pond from the end of February to early March (the depth of the pond is 0.3-0.4 meters). The planting area of ​​aquatic plants accounts for 1 / 3 of the pond area, and the planting area of ​​sinking aquatic plants, floating aquatic plants and emergent aquatic plants is 1 / 3 of the planting area. 3. The sinking aquatic plants are elodea, the floating aquatic plants are water peanuts or mixed planting of water peanuts and water hyacinths, and the emergent aquatic plants are reeds. Aquatic plants are planted in strips with a plant spacing of 2-3m and a row spaci...

Abstract

The invention discloses a method for mixed culture of crabs, shrimps and mandarin fishes. The method comprises the following steps: (1) water in a pool is 0.3-1.5m deep, the slope ratio of the pool is 1:3, high-protection facilities are built at the periphery of the pool, and an automatic aerator is arranged per 667m<2>; (2) the plant area of waterweeds in the pool accounts for one third of the area of the pool, and at the same time, snails are stocked; (3) at the end of March, 500-700 crabs per 667m<2> are stocked based on the standard of 80 crabs per kg, 5-7kg of post larvae of lobsters per 667m<2> are stocked in the first and middle third of April based on the standard, 7-10 mandarin fishes per 667m<2> (in 5 cm length) are put in the last third of May, and 6 kg of fingerling silver carps per 667m<2> are put in the first third of June based on the standard of 800-1000 fingerling silver carps per 1kg; (4) overhead price river crab feed cp.40% is used, supplementary with wheat and bean pulp, feed amount daily is controlled to 4-6% of the weight of shrimp and crab; and (5) a water quality regulator is used for one time per 15-30 days. On each day, shrimp and crab shell auxin and allicin, the amount of which account for 1-1.5% of the amount of feeds, are added.

Description

technical field [0001] The invention relates to the field of aquatic product cultivation, in particular to a method for polyculture of crabs, shrimps and mandarin fish. Background technique [0002] With the improvement of people's living standards, the consumption of rare aquatic products has also increased. Due to the high requirements for individual breeding of rare aquatic products, most of the famous and precious aquatic products have been cultured in a single breeding method for a long time. The low utilization rate and high breeding cost have affected fishermen's breeding enthusiasm, so that the supply of crabs and mandarin fish among the famous and precious aquatic products has been in a state of short supply, and their prices remain high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for polyculture of crabs, shrimps and mandarin fish, which can effectively improve the utilization rate of wate...
