Evaluation of selected substrates for collection of hatchery reared black-lip pearl oyster (Pinctada margaritifera) spat
An experiment was conducted to investigate the effect of collector materials and position on Pinctada margaritifera spat attachment. Settlement on polyethylene pipes (54.6%) was significantly higher (P < 0.05) than on plastic baskets (25%). Significantly higher (P < 0.05) spat catch was recorded from the collectors which were installed on lower height of settlement tank than upper. The number o...
