Fry breeding device with filtering device for mariculture of flatfish and fry breeding method

Abstract

The invention discloses a fry breeding device with a filtering device for mariculture of flatfish and a fry breeding method. The fry breeding device comprises a fry breeding device shell, a filteringbox, a first fixing plate, a first rotating bolt, a rotating rod, a first spring plate, a second rotating bolt, a reset spring, a second fixing plate, a second spring plate, a clamping plate, gauze, afine filtering layer, an activated carbon layer, a water outlet, a top plate, a rubber plate and an anti-skid pad. The filtering box is arranged in the fry breeding device shell; a base plate is welded at the bottom of the filtering box; a threaded rod is welded to the top of the base plate; and the top of the threaded rod is sleeved with a side plate. According to the fry breeding device with the filtering device for mariculture of the flatfish and the fry breeding method, the structure is simple, the operation is convenient, gravel is removed through the gauze, fine particles are removed through the fine filtering layer, finally, smell is removed through the activated carbon layer, growth and development of fry are better facilitated, meanwhile, manual operation is not needed, time andlabor are saved, and the device and the method can be used conveniently by users.

Description

technical field [0001] The invention relates to the technical field of flounder mariculture, in particular to a seedling raising device with a filter device and a seedling raising method for flounder mariculture. Background technique [0002] Plaice is a kind of fish, collectively referred to as bony fishes Plaiceidae, a type of flounder, with a long oval body, oval or diamond shape, flat sides, short and high tail peduncle, and generally requires mariculture; traditional Plaice mariculture is directly placed in the breeding box, and the seawater is mixed into the seawater through the seawater drainage tube. There is no filter device, and the seawater impurities cannot be filtered, which is not conducive to breeding, and it is necessary to manually fix the seawater drainage tube into the seawater, which is time-consuming and laborious, and increases the work intensity. It is unfavorable for the user to use; For these defects, it is necessary to design a seedling raising devi...
