Abstract

The invention relates to an automatic collection device for semi-floating fish eggs. The automatic collection device is characterized in that the automatic collection device comprises a right-angle bent pipe, a suspension rope, a net bag and an inflating pipe, the right-angle bent pipe is suspended in an egg laying pond through the suspension rope and the suspension rope is tied at the bent position of the right-angle bent pipe; the right-angle bent pipe comprises a vertical pipe section and a transverse pipe section, a weight is arranged at the lower end of the vertical pipe section to keep the vertical pipe section to be in a vertical state when the right-angle bent pipe is in a suspended state; the mouth of the net bag is sheathed at the rear end of the transverse pipe section and is tightly tied through a tying rope; and the inflating pipe is inserted into the vertical pipe section by certain length from the bent position of the right-angle bent pipe. The automatic collection device for the semi-floating fish eggs has the advantages that the device is simple, convenient and feasible to operate, the manufacturing cost is low, the labor intensity can be reduced and the working efficiency is improved; the damage to the fish eggs is reduced, the collection rate of the fish eggs is high and the hatching rate of fish fries is high; and the structure is simple, the space of the egg laying pond is not occupied, the fish egg collection and the inflation can be conducted at the same time, additional investment is not required and the automatic collection device is particularly suitable for the artificial breeding of seawater and freshwater fishes such as four major domesticated fish and the like which lay semi-floating eggs.

Description

technical field [0001] The invention relates to an automatic collection device for semi-floating fish roe, which belongs to the technical field of fish artificial reproduction. Background technique [0002] Fish artificial reproduction refers to the method of controlling fish development, maturation, spawning and hatching under artificial conditions according to natural breeding habits. The artificial breeding of fish can provide a stable and large amount of seedlings for aquaculture, which provides a material basis for the sustainable development of aquaculture. Therefore, artificial breeding of fish is the basis for the rapid development of aquaculture. And the collection of fish eggs is the key to the success of fish artificial reproduction. Therefore, doing a good job in fish collection is of great significance to fish artificial reproduction. [0003] After broodstock is injected with oxytocic agent, it takes a certain period of product activity to complete the spawni...
