Preparing method for fish oviposition collector

Abstract

The invention discloses a preparing method for a fish oviposition collector, and relates to the technical field of the aquaculture. The method comprises the steps: cutting fresh wickers with the length ranging from 20 cm to 50 cm, smoothing the cut wickers, and putting the wickers into a solution to soak for 1-3 hours; after the solution soaking, wrapping the wickers by at least two layers screen gauze with soaked unguent, using a layer of the screen gauze without the unguent as an outer layer to wrap the wickers, and branches and leaves of the wickers expose out of the screen gauze; fastening the middle of 5-10 roots of the wickers wrapped by the screen gauze, attaching a lifting rope on the fastening position, and the upper end of the lifting rope is attached to a cross rod; fixing the cross rod on the position of 5 cm above the water surface, the fastened wickers naturally drooping to the position of 15-20 cm below the water surface, and the fastened wickers can be used as the collector for the fish oviposition. The preparing method for the collector of the fish oviposition is suitable for the large scale production of the fish with viscidity egg. The preparing method for the collector of the fish oviposition has the advantages that the utilization method is easy, the operation is convenient and rapid, the survival rate of incubation is high, the manufacturing cost is low, the material for preparing the collector is easy to get, and the fish fry production is unrestrained by the material.

Description

Technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for preparing a fish spawning collector. Background technique [0002] Before there were special fish nests for fish with sticky eggs, the eggs of carp and crucian were laid on the aquatic plants in the pond, and then naturally hatched and sprouted naturally. This primitive production method was low in productivity and was not suitable for large-scale fishery production. Summary of the invention [0003] The purpose of the present invention is to provide a method for preparing a fish spawning collector to solve the above technical problems. [0004] The technical problem to be solved by the present invention is realized by the following technical solutions. [0005] A fish spawning collector, which is characterized in that it is made up of 5-10 wicker stalks, all wickers are tied together in the same way and tied in the middle. The strapping place is tied with a sling, and th...

[0002] Before there was no special fish nest for sticky egg-laying fish, the eggs of carp and crucian carp were laid on the aquatic plants in the pond, and then hatched and emerged naturally. This primitive production method has low productivity and is not suitable for large-scale fishery production.
