First of all, fish farmers carefully squeeze out the fish eggs in the female fish, which is the first step to assist the fish gel cake. Then he grabbed a male fish, put his teeth on his abdomen, put his sperm on the ridge of the male fish, and then directly stirred the fish eggs by hand. This is an extremely primitive fertilization technique, with no microscope and no test tube. Then wash these fish eggs with clear water. This process needs to be repeated eight times until the water becomes clear. Fish eggs floating on the water after cleaning are useless, so they should be removed with straws.
Secondly, next, the fish farmers will put the whole fish eggs in a bottle filled with water, and it takes about one month for the fish eggs to hatch. On the 25th day, if the fish eggs are still alive, there will be two small black spots on the fish eggs, which are the eyes of the fish. After the incubation period, the breeder will empty the water in the bottle, then pour the fish eggs on a net board and cover the soup with water. At this time, it takes ten to 15 days for fish eggs to hatch into small fish. When the fry hatch, they will go through the net and enter the pool below. These fry will take nutrients from eggshells in the first 18 days and then feed them with special fish meal feed. Eight months later, the original fry will meet. When it grows to ten centimeters long, the smaller fish in the pond may be eaten by the big fish, so fish farmers need to classify them according to their size.
Third, the smaller fish will fall into the pool from the gap, while the big fish will stay on it, then pour them into the bucket and move to another pool. /kloc-after 0/8 months, the fry will enter adulthood, and it is time to serve on the table, and then they will be transferred to the artificial pool. After breeding for a period of time, it can be put on the market for our consumption. But before going to the table, raising fish will make them repeat the previous process, thus hatching more fry.
