Embodiment Construction

[0017] The present invention is described in detail in conjunction with the accompanying drawings.

[0018] combine figure 1 , figure 2 As can be seen, the method for concentrating on getting ovum of sand pond snakehead of the present invention comprises steps as follows:

[0019] ① Formulate an egg collector; the egg collector is composed of a carbon fiber round rod 1, a stainless steel slot 2, a connecting rod 3, and a plug 4. One end of the stainless steel slot 2 is movably connected to the connecting rod, and the other end is provided with a plug hole; The two ends of the carbon fiber round rod 1 are inserted into the stainless steel slot 2, and blocked with a plug 4 to make a row-type ovipositor;

[0020] ② Splicing: Splicing multiple row-type ovipositors to make triangular ovipositors, square ovipositors, herringbone ovipositors and other shapes, and then placed on the bottom of the pool for concentrated egg collection;

[0021] ③Egg collection: Collect the egg colle...

Abstract

The invention discloses a concentrated ova-collecting method for Odontobutis obscura. The method comprises the following steps: manufacturing an ova collector, wherein the ova collector is formed by acarbon fiber round rod, a stainless steel slot, a connecting rod and a plug, and the ova collector is spliced to form shapes, such as a triangle, a square and a Y-shape; collecting ova; scraping by using a stripper, and stripping without the damage, concentrating the ova and hatching, and ending the ova collecting process. The positive effect of the method is that the row-type ova collector is used for collecting the ova, and the damage rate in the ova collecting process is less than 10%. The features of the carbon fiber round rod are combined, the ova are not damaged by the separation between the carbon fiber round rods, and the partial ova adhered to the carbon fiber round rod can be easily taken out by the stripper. Because the whole ova collecting process is performed in water, the ova cannot be stacked, and the damage to the ova is further reduced. Through multiple times of the practice, the damage of the method is less than 10%.

Description

technical field [0001] The invention relates to a culture technique of sand carp, in particular to a method for collecting eggs of sand carp in a concentrated manner. Background technique [0002] Sand snakehead is favored by consumers because of its tender meat and rich nutrition. At present, the number of wild sand snakehead is small and scattered, and the production of natural waters is getting lower and lower, and its hatching environment is constantly threatened. With the improvement of people's living standards, the market's demand for sand snakeheads is increasing day by day. Some farmers adopt egg collection for centralized hatching, and use tiles and PVC pipe fittings to place them in ponds. Blade scraping, in the process of scraping, at least half of the eggs are damaged to varying degrees, this method of concentrated egg collection is counterproductive and does not improve the hatching rate of eggs. Contents of the invention [0003] The object of the present i...
