1, the water source requires pollution-free streams, which are introduced into the pond through channels, enter from one end of the pond, and exit from the other end, mainly relying on running water cultivation. The size of the pond is generally 50-1100m2, and the water depth is about1m. It is best to put some gravel in the pond to hide the grouper, or build a shed in the corner of the pond to shade the sun, so as to avoid the influence of too strong light on the growth of grouper in summer.

2. Artificial breeding needs to be fed with bait, which can be fed with prawn bait or carp bait with high protein content, and the protein content should be above 30%. The feeding amount depends on the water temperature, the size of the fish and the weather conditions, and it is generally appropriate to eat 80% of the fish. Bait feeding method: after the total amount is determined, feed it slowly, and then feed it after eating, because groupers don't like submerged bait.

3. The daily management requirements of water quality are clear, mainly running water. If the light is too strong in summer, shade it in time. When it rains heavily, the water inlet should be closed to prevent muddy water from rushing into the pond and the grouper from escaping.
