Natural fish egg collection technology

The hatching season of fish is mostly during the period of "clear to early" and "early summer". At this time, rivers, ponds, lakes, etc. where fish are spawned can be selected, artificially set materials (ie, fish nests) that facilitate the attachment of fish eggs, and natural fish eggs.
Usually, broodstock (female spawning females) are mostly fibrous roots, sagebrush grass, snapdragon (algae) and brown hairs of willows, among which the willow root is the best because of its dense root fibers and texture. Flexible, not easily broken and rot, is conducive to the normal spawning of eggs and the extraction of egg mass (grain). The branches and leaves of the snapdragon are more dilute and tender. They are easily broken and rotted by the fish when they lay eggs. They also affect the normal spawning and extraction of fish. Eggs (grain).
The willow roots should be grown in water, while the grasses and snapdragons are all plants that grow in the water. They should be grown in shallow water because they grow in shallow water and have dense leaves that facilitate the attachment of fish eggs. After the collection, the roots must be cut off and washed to make fish nests. When using brown hair as a fish nest, it must be boiled first, remove the contained harmful substances, and then expose it to sunlight and expose it to dryness. The brown rope used for the nest must also be boiled before use. Plastic ropes can be used when making fish nests, with good toughness, light weight, good drainage, and straw ropes are generally not to be used.
Commonly used fish nests include: round hollow nests, horizontal single nests, and nested nests. The nesting practice is to take a length of 0.5 to 0.6 meters of willow, swamp, snapdragon or brown hair. Take about 10 each. , Integrate suitable, tie it every 10 to 11 centimeters, and clip it on plastic or brown rope. The two ends of the rope are tied to wooden poles or bamboo rafts and put into water. Each nest is to be floated on the water, and the stones below it are fixed and stable.
Broodstock spawning usually occurs in the early morning of the day when they are laying out, or in the morning when the weather is hot, thundering and raining, or in the morning when it rains on sunny days. It should be noted that at this time the fish can not be disturbed to lay eggs regularly, and check the fish nest at any time. If the fish eggs have been collected or have a large amount, they should be promptly retrieved, hatched, and replaced with new fish nests in time to facilitate collection of fish eggs.
