Five kilos. The water source for breeding grouper requires pollution-free streams to be introduced into the pond through channels and enter the other end from one end of the pond, with running water as the main source. The pond is 50 to 100 square meters, and the water depth is 1 meter. It is good to put some gravel in the pond, so that the groupers can hide, or you can set up a shed in the corner of the pond for shade to avoid the influence of too strong light on the growth of groupers in summer.
