Abstract An inexpensive method for mass rearing larvae of the commercial mud crab, Scylla serrata, is described. Water quality was maintained within the recirculating system by continuous filtration and eggs were hatched from females which had been induced to spawn by eyestalk ablation. Incubation periods conformed to a Belahadrek rate/temperature equation in the form of D=a(T-α). Survival and speed of development from first zoea to first crab stage were maximized at temperatures approaching 27°C, and by increasing Artemia nauplii concentrations (food) from 5 to 30 ml as the larvae progressed. Megalopal survival and metamorphosis were aided by a food supplement of macerated prawn muscle. In the most successful trial 26% of first zoeae survived to first crab stage after 30 days.
