The effect of salinity and temperature on the larval development of the freshwater prawn, Macrobrachium australiense Holthuis, 1950 from south eastern Queensland, Australia

Larvae of the freshwater prawn Macrobrachium australiense were reared to postlarvae at various combinations of salinity and temperature (salinity, 0 to 35‰; temperature, 15 to 35°C). Metamorphosis was not recorded at salinities higher than 15‰. However, salinities within the range 0 to 15‰ did not markedly affect survival. No larvae metamorphosed at 15 or 35°C but the rate of development was highly dependent on temperature within the range of 20 to 30°C, being fastest at 30°C, slowest at 20°C
