Problems solved by technology

[0002] At present, most young crab farmers adopt the traditional manual digging method to catch young crabs. Generally, 5% to 10% of the young crabs are mechanically damaged by this fishing method, and the labor input is relatively large.

Embodiment Construction

[0018] A kind of Chinese mitten crab juvenile water peanut accumulation fishing method comprises the following steps:

[0019] (1) Cut off the water peanuts: after entering November, the young crabs basically stop growing. At this time, the water peanuts around the young crab cultivation ponds are cut off, and the water peanuts between the ponds are uprooted.

[0020] (2) Scattered and piled water peanuts: the water peanuts harvested around and pulled up from the middle are evenly scattered and piled up in the young crab cultivation pond, and the fresh weight of water peanuts of the size of each haystack is controlled at about 15-20 kg.

[0021] (3) Drainage to lure juvenile crabs into the haystack: start draining the day before the juvenile crabs are sold, and after the pond water is drained, more than 90% of the juvenile crabs are concentrated in the piled water peanut haystack.

[0022] (4) Catch young crabs for the first time: After the pond is drained, open the haystack, ...

Abstract

The invention discloses a method for fishing young eriocheir sinensis through alternanthera philoxeroides stacking, and relates to the fishing technology of young eriocheir sinensis. The method comprises the steps of cutting off alternanthera philoxeroides, scattering and stacking the alternanthera philoxeroides, draining water and inducing young eriocheir sinensis into the alternanthera philoxeroides stacks, fishing young eriocheir sinensis for the first time, injecting fresh water, fishing young eriocheir sinensis for the second time, and tracing and surveying the young eriocheir sinensis under-pond surviving rate. By the adoption of the method for fishing the young eriocheir sinensis in the alternanthera philoxeroides stacks by draining water repeatedly, the method is simple, operation is convenient, the young eriocheir sinensis under-pond surviving rate is significantly improved, and the bottleneck problem that the young eriocheir sinensis under-pond surviving rate is low in the pure fresh water area is solved.

Description

Technical field: [0001] The invention relates to a fishing technique for juvenile Chinese mitten crabs, in particular to a method for piling up and fishing Chinese mitten crab juveniles with water and peanuts. Background technique: [0002] At present, most young crab farmers adopt the traditional manual digging method to catch young crabs. Generally, 5% to 10% of young crabs are mechanically damaged by this fishing method, and the labor input is relatively large. Due to the rising labor costs, in order to reduce costs, reduce the mechanical loss of young crabs, and sell young crabs more smoothly, many young crab breeders use the whole pond to splash low-concentration drugs to force young crabs out of haystacks and caves, and then catch them. The juvenile crabs caught by drugs and the juvenile crabs caught by traditional manual digging methods are invisible from the appearance, and there is no mechanical damage. Unknowing adult crab farmers prefer to buy juvenile crabs caugh...
