Floating type underwater bait casting device inside net cage

Abstract

The invention relates to a floating type underwater bait casting device inside a net cage, and belongs to the field of bait casting devices. The bait casting device comprises a charging bin. The charging bin is connected to a bait casting pipeline through a main pipeline. A discharging hole for discharging bait is formed in the bait casting pipeline. The bait casting pipeline is annular. A material mixing bin is arranged between the main pipeline and the bait casting pipeline. The material mixing bin is connected with the bait casting pipeline through a branch pipeline. An immersible pump A is connected to the main pipeline through a pipeline. The material mixing bin is connected with an immersible pump B through a pipeline. A floating object is fixedly arranged on the main pipeline. The bait casting is large in range and uniform, extrusion, friction and fight during fish forage can be avoided, and the phenomenon that seabirds scramble for bait can be avoided by means of underwater bait casting.

Description

technical field [0001] The invention relates to a floating underwater bait throwing device in a net cage, which belongs to the field of bait throwing devices. Background technique [0002] When using net cages to breed fish, it is necessary to set a bait feeder in the net cages to feed the fish. Most of the traditional bait feeders are jet feeders. The traditional bait feeder sprays the feed to the water surface, and the bait will float on the water surface until it is wet before sinking. During the floating period of the bait, the fish will gather on the water surface when retrieving bait. Due to the small space where the bait appears, the fish squeeze and rub against each other, easily causing body surface damage, and then leading to infection and death; the bait floating on the water surface may also cause seabirds to snatch food, and even attack fish, resulting in fish death die. Contents of the invention [0003] The object of the present invention is to provide a f...

Most of the traditional bait feeders are jet bait feeders. The traditional bait feeder sprays the feed to the water surface, and the bait will float on the water surface until it is soaked before sinking. During the bait floating period, the fish will gather on the water surface when they are retrieving bait. Due to the small space where the bait appears, the fish squeeze and rub against each other, easily causing body surface damage, and then leading to infection and death; the bait floating on the water surface may also cause seabirds to snatch food, and even attack fish, resulting in fish death die
