| Abstract | The influence of water quality, sediment quality, and microbial community factors on the growth of mud crabs (Scylla paramamosian) at different stocking densities was examined. The experiment involved stocking mud crab culture at four densities: (T-1) 1 crab/m2, (T-2) 1.5 crab/m2, (T-3) 2 crab/m2, and (T-4) 3 crab/ m2, with triplicates for each density. The growth performance of the mud crab over a 101-day culture period was monitored. The survival rate at 1 crab/ m2 was significantly higher than at 2 and 3 crabs/m2 (P < 0.05). Additionally, the average production of 1 and 1.5 crabs/m2 was significantly higher than at 3 crabs/m2 (P < 0.05). Nitrite levels in sediment at the 3 crabs/m2 stocking density were significantly higher than at the 1 crab/m2 stocking density during the culture period. The dominant phyla found in the ponds were Phylum Cyanobacteria, Actinobacteria, and Bacteroidota, with no microbial pathogens detected. The recommended stocking densities for mud crab culture range between 1 crab/m2 and 1.5 crab/m2, as these densities are deemed suitable for maximizing productivity in mud crab farming |
