Sexual dimorphism in N-acetyltransferase and melatonin levels in the giant freshwater prawn Macrobrachium rosenbergii de Man
N-acetyltransferase (NAT) and melatonin were determined in the optic lobe of the giant freshwater prawn Macrobrachium rosenbergii de Man. The prawns were divided into three groups: fast-growing 'jumper' males; slow- growing 'laggard' males; and females. Both NAT and melatonin lev...
