Embodiment 1
[0018] The artificially captured glass eels were collected, transported to the laboratory, and temporarily kept in glass jars sterilized by potassium permanganate. The size of the glass jars was 70cm×40cm×50cm, and the size of the glass jars was adjusted appropriately according to actual needs. The salinity of the water body is consistent with the salinity of the captured water area, and 300 glass eels are temporarily kept in each tank, and the water depth is kept at 25cm. Place tiles and shelters at the bottom of the glass tank to provide a sheltered place for eel seedlings to inhabit. Oxygenation by the oxygen pump to keep the dissolved oxygen in the water above 6.0mg / L. Drain 1 / 5 of the seawater every day, and add 1 / 5 of the fresh water at the same time. After 5 days, the eel fry are completely transferred to the fresh water for cultivation. Days later, the water temperature rose to 25°C, and the water temperature at 25°C was kept constant. No bait is fed during the salt ...
