Intercropping rotation-grazing purse net device for enclosing crabs and soft-shell turtles and intercropping rotation-grazing method thereof

Abstract

The invention discloses an intercropping rotation-grazing purse net device for enclosing crabs and soft-shell turtles and an intercropping rotation-grazing method of the device. The intercropping rotation-grazing purse net device for enclosing the crabs and the soft-shell turtles comprises an outer-layer purse net, monitoring cages, an inner-layer purse net, separation purse nets, separation cages, a temperature senor, a water temperature displayer, a crab raising enclosing area and a soft-shell turtle raising enclosing area. The intercropping rotation-grazing method of the intercropping rotation-grazing purse net device includes cultivation purse net setting and building, pest eliminating, seeding, snail putting, crab and soft-shell turtle seedling stocking, crab seedling secondary stocking, inspection, temperature measurement, feeding, catching and rotation-grazing breeding. The device enables the river crabs and the Chinese soft-shell turtles to be bred simultaneously, can have the advantages of breeding of a single species, also has the advantages of intercropping, is little in daily management and protection labor intensity, high in aquatic product quality, high in economic benefit per unit area and convenient and fast in application method, and facilitates centralized popularization and application of advanced technologies of temperature measurement feeding management and protection, temperature measurement catching and the like.

Description

technical field [0001] The invention relates to a net used for breeding aquatic products, in particular to a net used for breeding crabs and soft-shelled turtles. Background technique [0002] The scientific name of river crab is Chinese mitten crab, also known as hairy crab and hairy crab. The scientific name of soft-shelled turtle is Chinese soft-shelled turtle, also known as soft-shelled turtle and turtle. Both of them have won the market for their tender meat, delicious taste and rich nutrition. [0003] After decades of ups and downs, river crabs and Chinese soft-shelled turtles have formed a huge industrial scale from point to surface. Today, crabs and soft-shelled turtles have become pillar industries in agricultural production in some provinces, cities (counties), and have formed scientific research, Production, processing, and trade are one-stop industrial chains. In lakes, reservoirs, and large-scale rivers, people use seine methods for artificial breeding of spec...

AI Technical Summary

Problems solved by technology

However, the artificial breeding density of existing special aquatic products is high, and the biological conditions of natural water bodies are difficult to meet the growth requirements of aquatic products

In the existing culture mode in the lake area, the artificial breeding of crabs and soft-shelled turtles is mostly monoculture or polyculture with fish. Monoculture makes the artificial breeding care more targeted, which is beneficial to the increase of output, but it is difficult to improve the quality

For example, crabs eat a lot of grass. In the process of artificial breeding and nursing, it is not enough to rely solely on aquatic plants in the seine waters. They must be mowed and fed from non-seine areas. Fresh, not conducive to the growth of crabs

However, soft-shelled turtles hardly eat grass, and the growth of aquatic plants in the net enclosure is not conducive to the soft-shelled turtles' search for food, which directly affects the growth of soft-shelled turtles.
