Background
Siniperca chuatsi, also called mandarin fish, fat mandarin fish, quaternary flower fish, flower crucian, etc., belongs to the class of bass, mandarin fish, is a fresh water noble fish, is tender in meat, delicious, high in protein content, less in thorn and famous, and is a delicious dish on a celebration banquet. In recent years, with the adjustment of the structures of the national cultured varieties, hot flashes of the cultured mandarin fish are raised in various places, however, the mandarin fish belongs to benthonic life and is hidden in grooves, ravines and caves, so that the recapturing rate of the cultured mandarin fish is low and a good capturing method is not provided. The mandarin fish in the wild environment perchs in the places with dense rubble, flowing water in and out, rich water grass, rich fish and shrimp, clean water quality and no pollution. In the culture pond, mandarin fish has the habit of clustering and hole-living at the bottom of the pond, and is hidden in the groove in daytime, the net-pulling catching net surfing rate is very low, and the mandarin fish is easy to catch by bare hands but is easy to hurt hands and has low efficiency.
In the traditional fishing mode, fishing personnel only adopt trawl to catch for many times and then catch in a dry pond, so that a great deal of labor force is wasted, and fish injury is easy to occur. The familiar fisher can capture 20-30 kg in 1 hour, and is suitable for small amount of marketing. When a large amount of water is on the market, shallow pool water is required to be put, and the water is caught by using a ground-pulling net, a foil fish catch, a fishing reel or manual catching. The traditional net is difficult to catch a large amount of mandarin fish, and because the traditional net is too large and too heavy, the labor intensity is high during the catching operation, the bottom mud of the pond is easy to enter the net, the net is seriously damaged, the catching amount is small, the catching effect is poor, the catching rate is less than 20% of the pool, and the missed mandarin fish is easy to be injured and frightened.
