Evaluation of water quality parameters, growth and proximate composition of juvenile crab, Portunus pelagicus cultured in RAS and non RAS system

Juvenile blue swimming crab, Portunus pelagicus were reared over 31 days in two different systems namely recirculating aquaculture system (RAS) and conventional aquaculture system (CAS) to evaluate the water quality parameters, growth, and its body composition. The juvenile crab, weighing of 0.95 ±...
