Carrying capacity of an estuary for prawn farming

Enrichment of organic matter in the sediment occurred when the carrying capacity of an estuary for prawn fanning has been exceeded. By determining the organic matter in the sediment, the carrying capacity which will be basis for authority to issue license was detennined. Subsequently, a scientific b...
