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 bio¢ltration) and micro-algae (Chlorella or
Chaetoceros) supplementation (daily supplementation
at 0.1^0.2million cellsmL1 or maintenance at
1^2millions cellsmL1), six di¡erent types of
rearing systems were tried. The combination of a
green-water batch systemfor early stages and a recirculating
system with micro-algae supplementation
for later stages resulted in the best overall performance
of the crab larvae
