Grow-out bottom cages Zigzag juveniles grow at a rate of 5mm per month and are kept in suspended cultures until 25mm in shell height. Scallops remain in these enclosures for a period of five to six months until they attain adult size. Bottom culture has shown to provide the best results in terms of growth rate and survival rate for Pecten ziczac . Furthermore, one of the culture sites used at present has given inconsistent results in terms of survival rate where unexplained mortalities have occurred during the summer months. Research is presently focused on the improvement of techniques to enhance potential for the culture of the sand scallop.
Considerable scope exists for research studies in the above fields.
