Large mudskipper catching device and catching method thereof

Abstract

The invention discloses a boleophthalmus pectinirostris catching device and a catching method thereof. The boleophthalmus pectinirostris catching device comprises a fish hole excavator and long fish cages and is characterized in that a walking tractor head is installed between a front floating body and a back floating body of the fish hole excavator, the left side and the right side of the tractor head are provided with rolling cages, and the peripheries of the two rolling cages are both provided with excavating plates; square frames and circular frames are arranged in each long fish cage, wherein the periphery of the long fish cage is provided with a fish cage outer net, the two sides of the long fish cage are provided with fish cage holes, and the two ends of the long fish cage are each provided with a dead end inlet, a fish discharge port and a closing binding belt. The boleophthalmus pectinirostris catching method achieved through the boleophthalmus pectinirostris catching device comprises the steps that firstly, the water depth of a fishpond is controlled to be equal to the height of the long fish cages; secondly, the long fish cages stretch across the water surface of the fishpond, the fish hole excavator enters the portion, surrounded by the long fish cages, of the fishpond to walk, the excavating plates of the excavator are inserted into fishpond sludge to destroy fish holes, and fishes are hidden in the long fish cages to be caught. The catching device has the advantages of being simple, easy to manufacture and capable of saving the fish catching manpower and material resources, reducing the labor intensity and greatly improving the fish catching efficiency.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a mudskipper catching device and a catching method thereof. Background technique [0002] The large mudskipper Boleophthalmus Pectinirostris (Linnaeus), also known as flower jumping fish, jumping fish and jumping pike, is abundant in the coastal areas of Zhejiang, Fujian, Guangdong, Guangxi, Hainan and Taiwan in southern my country. It likes to drill holes and live at the bottom In the muddy low-tide area, or the estuary tidal flat where salty and fresh water meet, the big mudskipper crawls, jumps and forages on the mud with the help of its pelvic fins. It has a large head, a wide mouth, and a nearly cylindrical body with irregular green Brown spots, generally 10-20 cm in length and 20-50 grams in weight. The giant mudskipper has very keen eyesight, one eye is dedicated to searching for food, and the other eye is vigilantly watching possible predators. Mudskippe...
