Embodiment 1
[0035] The following is an example of how to cultivate 600 catties and the size of 4 tails / jins eel females after cultivation.
[0036] A kind of broodstock culture method of large-scale artificial propagation of yellow eel, its steps are as follows:
[0037] 1. Erection of cages: 10 cages need to be erected in the pond: the mesh is 0.7mm and the area is 2×2M 2 , the water depth in the cage is 15cm, and the cage is 60cm above the water surface. Put 100kg of water peanuts in each cage.
[0038] 2. Putting fingerlings: The putting time is mid to late July every year, and the water temperature is constant above 26℃. The wild fish species with a size of 15 fish / catties are put in, and the stocking density is 4.5 catties / M 2 . 18 catties of wild fish are placed in each cage. One week before the fingerlings are put in, the cages are disinfected with povidone-iodine at a concentration of 5g / M 2 .
[0039] 3. Food taming: start feeding after 3 days of feeding the fingerlings. ...
