Abstract

The invention discloses an under-ice collecting device for protosalanx hyalocranius parents and a using method of the under-ice collecting device, relates to the technical field of protosalanx hyalocranius artificial propagation, and aims to solve the problem of high death rate of protosalanx hyalocranius parent collection in a large water surface in the prior art. According to the under-ice collecting device for the protosalanx hyalocranius parents, protosalanx hyalocranius belongs to middle-upper layer fishes according to the living habits, on the basis of an existing netting gear, floating rods and floating balls are additionally arranged to increase the floatability of the netting gear, and therefore it is guaranteed that the netting gear floats under ice. Meanwhile, the characteristic of phototaxis of the protosalanx hyalocranius is utilized, waterproof rechargeable LED lamps are additionally arranged, and the protosalanx hyalocranius is induced into the netting gear. The under-ice collecting device is simple in structure and convenient to operate, and manpower and material resources for net picking are greatly saved; and meanwhile, the survival rate of parents can be greatly increased, the use efficiency of the parents in the artificial propagation process is improved, the catching amount of the parents can be greatly reduced, and the number of populations participating in self-propagation is guaranteed. The under-ice collecting is applied to the aquatic product field.

Description

technical field [0001] The invention relates to the technical field of artificial reproduction of whitebait, in particular to an under-ice collection device for the parent of whitebait and a method for using the same. Background technique [0002] Whitebait (Protosalanx hyalocranius) is the largest individual fish in the Antheraceae family and the genus Protosalanx. It has high protein content, low fat content, and various trace elements. The value and economic value are quite high, and it is an excellent species for transplanting and multiplying on large water surfaces such as lakes and reservoirs. Whitebait is a cold-temperate fish, which spawns and breeds under the ice in Northeast China in December. At present, the transplantation of large whitebait in large water surfaces in Northeast China mainly adopts the method of breaking the ice in winter and releasing fertilized eggs. Taking Heilongjiang Province as an example, the output of whitebait in recent years accounts f...
