Raising Thai snakehead in shrimp ponds saves investment and yields good returns. The shrimp pond should have little mud, with shrimp as the main species, while Thai snakehead fry are also reared to size. Because Thai snakehead has good salinity tolerance, in ponds for Pacific white shrimp or giant river prawn, after the shrimp fry have been stocked for 10-15 days, when salinity is 2‰-5‰ the fish fry can be released directly, at 100-200 Thai snakehead fry per mu, feeding mainly on small, slow-growing shrimp fry. When harvesting shrimp, any Thai snakehead caught must be disinfected promptly
