Fishing period: The green shrimp grows very fast. There is a saying that "the forty-five days to catch the mother", that is, the larvae hatched from May to June can catch up with the broodstock after one month of growth, and can reach up to November. 3g～5g is the wintering period from November to March of the next year, and enters the breeding period from May to June. After completing the reproductive task, it begins to die in July. In August, it died in large numbers, and its life cycle is 14 to 18 months. . According to this habit, the cage net generally operates from June to November; during the wintering period from November to March, due to the low water temperature, the shrimps generally do not feed, and they lie in the deep waters for winter, and the fishing yield is significantly reduced. Generally do not work; to protect resources, April to June is a no-fishing period.
The cage net is a fixed cage net for catching small fish and shrimp for the seaside fishermen's city. The net is made of 8 wire as the skeleton, and the mesh is 15mm mesh to form a square and foldable cage net. The whole cage net is 2m long and is divided into 11 square wire skeletons. 10 internal small cages of 20cm×20cm×20cm squares, each with a trapped trapping hole on both sides of the cage. The trapping hole is a barbed netting. It is a conical fish net bag. When the prawns are misled by the trapping fish hole and crawled at the fish collection bags at both ends, they are arrested.
