Earthen jar cage for trapping mudskipper

Abstract

An earthen jar cage for trapping mudskippers comprises a reinforced frame; the reinforced frame is welded by upright reinforce columns; a cage body is formed by coating a lateral side surface with a mesh sheet wall, and the cage body is jar shaped; a fish inlet is symmetrically disposed on a middle portion of the reinforced frame coated by the mesh sheet wall; the fish inlet is connected to inward inverted whiskers; the inward inverted whiskers extend inwardly and are connected to an inward inverted whisker port; the inward inverted whisker port is fixed by an inward inverted whisker port pull cord; the cage top portion is connected with a cage body cover, and the cage cover is fixed by upper and lower steel ropes; the cage body cover is connected with a cage-lifting rope; one side is disposed with a fish discharging gate; one end of the fish discharging gate is fixed by a movable folding, and the other end of the fish discharging gate is connected with a gate hook; the fish discharging gate can implement opening and closing by moving up and forth under an action of the gate hook; a fish luring bag is placed at the cage bottom, and the fish luringing bag is fixed by a fish trapping bag pull cord.

Description

technical field [0001] The invention relates to a jar cage, in particular to a jar cage for trapping mudskippers, and belongs to the technical field of fishing cages. Background technique [0002] Mudskippers live on the tidal flats along the coast and below the high tide area of ​​the estuary. On sunny days, they emerge from their holes and jump to forage on the mud flats, feeding on benthic algae, small insects and other small organisms on the mud flats. According to the results of gastric content analysis, mudskippers mainly eat adherent diatoms. When the tide is low or the bottom of the pool is drained, mudskippers are often seen feeding on benthic algae, that is, their jaws touch the surface of the tidal flat, like plowing fields, swinging their heads from side to side and crawling forward to feed on benthic algae. Mudskippers have the habit of looking for food away from the water. When the tide is low, they often rely on the pectoral fin muscle stalk to crawl and jump...

Problems solved by technology

[0003] At present, when people catch mudskippers, they generally use traditional fishing tools such as spinning nets and lifting nets. The physiological and living habits of fish are different, the temperature difference between the north and the south is different, the water quality in reservoirs, big rivers, big lakes, and aquaculture water surfaces are different, the temperature difference is different, and the water body structure and shape structure are different in depth, that is, the fish in each water area are different. There are a...
