During the artificial propagation of eel in the southern region, there are many drawbacks to the collection of fertilized eggs using traditional methods. The biggest drawback is that about 30% of the fertilized eggs fall into the sediment in the pond, the hatching rate is low, and the fertilized eggs are distributed. Irregularities, poor lighting, etc., are prone to saprophytic diseases. If a "cage-type" squid fertilized egg collection method is adopted, artificial breeding of fertilized eggs by Feng Qi and Jian Jian can be achieved, and good results can be obtained. The specific method is as follows: First, the production of cages A cage is temporarily made from a dense mesh (1.5 mm mesh) of a Rashua flower, the size of which can be adapted to local conditions and determined by the number of broodstocks required. Second, the installation of cages Submerge the temporarily completed cage into the water (the water quality is good, the water depth is suitable for the pond, river or large cement pool with micro-flowing water) 1m - 1.5m, after fixing the cage, in the cage Pull a rope every 40 centimeters or so. Third, the preparation and loading of fish nests Fish nests can be made from gold cane or water plants developed from roots. After the fish nest is cleaned, disinfected and disappeared after toxicity, it is evenly distributed on the rope in the cage. IV. Anti-escape equipment In order to prevent eels from escaping from estrus to escape from the cage when spawning, cages must also be capped. You can use a piece of mesh to tightly cover the cage, sew the interface, leaving only a mouth of about 1 meter for the broodstock entrance. Fifth, the introduction of broodstock After selecting the broodstock, the broodstock can be placed into the cage at the required ratio from the entrance of the cage lid. If hormones are required for artificial aphrodisiac, hormones should be injected first and then the broodstock should be placed in the cage to be produced. Finally, the net is sewn. Cover entrance. Sixth, post-natal treatment After the eel's spawning is over, the cage lid can be dismantled to catch the broodstock, and all the fish nests and cages that adhere to the eel fertilized eggs are transferred to the hatchery for incubation.
