Description

Fish drifting egg collecting device suitable for different water depths

Technical Field

The utility model belongs to the technical field of fish early resource drifting sexual egg research equipment, concretely relates to fish drifting sexual egg collection system who is applicable to different water depths.

Background

The roe in the early development stage of the fish has no active swimming capability, so a large-scale biological net is usually used for collecting early resources of the fish. The fish floating egg collection usually adopts a netting and a fry collecting barrel which float on the water surface. The principle of use is that the collecting net is put into water at the collecting point with water flow, the collecting net is fixed by a rope, and fish eggs enter the fry collecting barrel through the netting.
