Because eel is expensive, it is necessary to choose full, strong and active fry for breeding, otherwise it will easily lead to death and direct cost loss. Generally speaking, this kind of fry is chosen to ensure the viability of eel, which is easier to survive in the later stage of aquaculture management. Water quality management. Eel, as a marine organism, can't live without a high-quality water environment. It is suggested to breed near Haikou. In order to restore the marine environment to the maximum extent, special breeding sites should be built in the breeding grounds. The water temperature should be kept between 8℃ and 30℃. At the same time, it should be noted that the current speed should not be too fast, which is easy to disperse the fish. In addition, oxygen tubes can be placed in the breeding ground to ensure that there is enough oxygen in the water to support their activities.
Breeding density. The breeding density needs to be adjusted according to the species of eels. Generally speaking, if it is a small eel, one square meter can hold about 120 eels. In the process of breeding, special attention should be paid to the growth of eels. Those who grow slowly can be taken care of separately to avoid the law of the jungle.
Sterilization treatment. Disinfection of eel culture is an important work of eel culture, which can be roughly divided into three stages. First of all, fry need to be disinfected before storage to remove all kinds of bacteria carried by fry; The second is to disinfect the seawater in the culture area before fishing, mainly to remove the bacteria bred by impurities left in the culture process; Finally, it is disinfected after harvesting, which is convenient for raising fish next time and avoids polluting seawater. Feed in. Eel is a carnivorous fish. Mainly fishing for small fish, shrimp, crabs, earthworms and other animal foods. When adult eels are sexually mature, their digestive organs will gradually shrink and stop feeding. Don't worry. After laying eggs, they will eat independently.
