A series of rearing trials in small 1L cones and large tanks of 30^100 L were carried out to develop optimal
rearing techniques for mud crab (Scylla paramamosain) larvae. Using water exchange (discontinuous
partial water renewal or continuous treatment through biofiltration) and micro-algae (Chlorella or Chaetoceros) supplementation (daily supplementation at 0.1^0.2 million cells mL1 or maintenance at 1^2 millions cells mL1),
six different types of rearing systems were tried. The combination of a green-water batch system for early stages and a recirculating system with micro-algae supplementation for later stages resulted in the best overall performance of the crab larvae
