Key Technical Points for Low-level Pond Culture of Green Grouper
I. Low-level pond renovation: Select low-level ponds with an area of 2000-3335 sq m and a pond depth of 1.8 m, where the water depth can always be maintained above 1.2 m. Retain the original earth embankments around the low-level pond, convert the pond bottom to a sandy bottom or sandy-mud bottom, and set water inlet and outlet openings at both ends of the pond. For every 1000 sq m of culture
