Stocking density for freshwater prawn Macrobrachium rosenbergii (Decapoda, Palaemonidae) in biofloc system

ABSTRACT The objective of this study was to evaluate the effect of stocking densities on productive performance of the freshwater prawn Macrobrachium rosenbergii in biofloc system. Experimental tanks (microcosms) with 0.20 m2 area were used as experimental units. The tanks were connected to two 300...
