Description
Technical Field
The utility model relates to a bionic ecological finless eel spawning nest.
Background
Monopterus albus (Monopterus albus) is one of important economic fishes in China, and is often living in water areas such as rivers, creeks, rice fields, ponds, lakes and the like in nature, and is favored to drill holes and nest, and foams are spit on the water surface near the hole to nest when spawning, so that fertilized eggs float in the foam nests to hatch; the finless eel can breathe air by means of the inner wall epidermis of the oral cavity and the laryngeal cavity, is hypoxia-resistant and strong in adaptability, and is suitable for intensive culture of thousands of households and enterprises in rural areas. However, because the artificial propagation hatchability and the emergence rate are low, and the supply of artificial fries is insufficient, the finless eel breeding fries mainly come from captured natural fries and are poor in quality, and the sustainable development of breeding is restricted.
The artificial fish breeding method includes two methods, that is, artificial insemination to obtain fertilized eggs and collecting fertilized eggs after parent fish spawns in spawning pond. One is that: by adopting an artificial insemination method, the finless eel lays eggs for many times a year, has a smooth body, squeezes or kills parents, is easy to lose the finless eel parents, is difficult to capture natural seedlings and has large workload; the other is as follows: the method of putting the finless eel parents into the spawning net cage or the parent spawning pond to naturally spawn and then collect fertilized eggs is adopted, if the aquatic grass nest or the mud nest is used, the aquatic grass nest or the mud nest needs to be built every time, so that the foam nest of the finless eel is easily damaged, and the eggs are difficult to collect when sinking to the bottom of the water.
