Specific operation in parent fish culture pond
The daily operation of managers in the culture pond will directly affect the feeding and cultivation of parent fish. As the large yellow croaker is very timid and easily frightened, the noise caused by the walking of the management in the breeding room, the bait, the holding of tools, and the sudden change of light caused by the opening of the door may cause the large yellow croaker not to eat or eat less for a while, and may cause wild swimming, so as to hit the pool wall or jump out of the pool, causing injury or death, affecting the normal development of the gonads of the parent fish.
