Water properties at fish cage culture In Sulaman Bay, Tuaran

Sulaman Bay is one of the aquaculture sites in Sabah that located at the west coast of Sabah, facing to the South China Sea. Most of the fish farming activities are operating in small scales and located along the channel from Sulaman Bay to the South China Sea. The study was conducted to evaluate th...
