Sepia-lycidas flow-type artificial fry breeding device

Abstract

The invention discloses a sepia-lycidas flow-type artificial fry breeding device. The sepia-lycidas flow-type artificial fry breeding device comprises a solid-liquid separation pond, an ammonia-nitrogen processing pond, a foam separation pond, a mechanical degerming device, an ultraviolet lamp and a culture pond which are sequentially connected to form a loop. The mechanical degerming device comprises a cylinder provided with an inner cavity; a piston capable of being driven by external force to slide in a reciprocating mode is arranged in the inner cavity of the cylinder; the cylinder is further provided with a liquid inlet channel and a liquid discharging channel, a liquid inlet valve rod is arranged in the liquid inlet channel, and a liquid discharging valve rod is arranged in the liquid discharging channel; the liquid inlet valve rod and the liquid discharging valve rod can be driven by the external force to control the inner cavity of the cylinder to be communicated with or insulated from the outside in a time-segmented mode; the liquid inlet channel is connected with a homogenate tank which can provide homogenate fluid; an air groove is formed in the inner wall of the cylinder; the distance between the two end portions of the air groove is greater than the thickness of the piston. The sepia-lycidas flow-type artificial fry breeding device has the advantages of being small in water change quantity, good in water processing effect, low in operating cost and manufacturing cost, good in stability, capable of producing a great number of fries and controlling the ammonia-nitrogen processing scale according to requirements, good in disease control effect and environmentally friendly.

Description

technical field [0001] The invention relates to a continuous factory aquatic product seed cultivation system, in particular to a flowing water artificial seed cultivation device for squid. Background technique [0002] In recent years, my country's aquaculture industry has developed rapidly, and the traditional extensive farming methods can no longer meet the needs of aquaculture development. It is an inevitable trend to replace the traditional extensive aquaculture method with the advantages of water saving, environmental protection, controllable water quality, and production not affected by climatic conditions by adopting the industrialized recirculating aquaculture system. At present, in the production of aquatic seedlings, the method of raising seedlings in large water bodies and concentrated water is mainly used. This method mainly uses artificial synthetic bait to feed seedling larvae, which is easy to pollute the water quality and cause the seedlings to suffer from di...
