Contents:
Three weight groups of juvenile prawn, M. nobilii, were raised at three stocking densities (22,38, and 77 prawns/m2) under three substrate conditions (sand, pebbles, and pebbles with shelter in the form of PVC pipe). Stocking density had a significant (P < 0.001) influence on the survival and growth of the prawn. A higher incidence of limb autotomy was recorded at the higher stocking density. Provision of pebbles and PVC pipe increased the survival, and mean growth rates, and reduced the percentage of limb loss.
