Problems solved by technology

[0004] Basket fish live in the middle and lower layers of the pond, and like to inhabit artificial ginseng reefs in the pond. They cannot be harvested by pulling nets and flooding, and the harvesting effect is not good by using bottom cage nets, sticky nets, trap nets and other nets.
At present, there is still no simple and quick way to catch basket fish to adapt to the large-scale production of basket fish ponds

Embodiment 1

[0025] In autumn, when the water temperature in the sea cucumber culture pond drops to 17°C, hang a small amount (2 pieces) of lures on the thick rope of the fishing net with a fishing line, and domesticate them 15 days in advance. After domestication, hang the lures from both ends of the fishing net to the middle from less to more, and the hanging forms of the lures are 1, 2, 3, 6, 12, 12, 12, 12, 6, 3, 2, 1. Wait for 30 to 50 minutes until the basket fish in a large area are lured into the fishing net to eat Chinese cabbage. When 100 to 150 basket fish gather around each cabbage, one person at each end of the fishing net will pull and fix it on the bottom of the net in turn. The thick rope that sinks to the bottom drives the basket fish to the center of the net and collects it in the floating cage. If the fishing nets around the pond carry out fishing operations at the same time, the harvesting efficiency of the basket fish in the pond can be improved.

Abstract

The invention discloses a method for domesticating and collecting cultured objects by adopting lures. The method is characterized by domesticating the cultured objects by adopting a fish net and lures; the domesticating is that the fish net is mounted in a culturing pond in a period of time before the cultured objects are collected, and the lures are arranged on the fish net; the number of the arranged lures is gradually increased from the edge to the center of the fish net so as to trap the cultured objects to be close to the center of the fish net. According to the method, raw materials are easily obtained; the cost is low; the preparation is simple; the cultured objects, particularly siganus oramin, in a pond can be collected efficiently.

Description

technical field [0001] The invention belongs to the breeding industry, and in particular relates to a method for domesticating and harvesting cultured animals by adopting traps. Background technique [0002] In recent years, affected by various factors, wild algae in sea cucumber culture ponds reproduce rapidly in the temperature-appropriate season. If not properly controlled, it will directly affect the survival and growth of sea cucumber culture in ponds. At present, in addition to using drugs to kill and artificially remove algae, polyculture of japonicus japonicus in basket fish has become the best choice for controlling wild algae in japonicus japonicus ponds at this stage. Because algicides will produce drug residues in sea cucumbers, resulting in slow growth and reduced stress resistance of sea cucumbers, and the decomposition of dead algae will produce harmful substances such as ammonia nitrogen and hydrogen sulfide, which will induce various diseases of sea cucumber...
