ABSTRACT:
A novel method is provided herein for the culturing of giant scallops from the egg stage to the juvenile stage. The method includes the following steps: firstly, obtaining and feeding native scallops. Secondly, inducing spawning in the scallop. Thirdly, selecting eggs surrounded by sperm in a preselected ratio of sperm/egg. Fourthly, hatching fertilized eggs at a preselected density in shallow dishes of water, thereby providing swimming larvae. Fifthly, removing the larvae after a preselected period of time, and re-suspending the larvae in deep larval tanks of sea water having food therein. Sixthly, periodically removing the larvae, re-suspending the removed larvae in larval tanks of the sea water and refeeding the re-suspended larvae with food in the sea water. Seventhly, after a period of time, allowing the larvae to settle on bottom of the larval tanks, in lighting conditions, and become spat while periodically changing the water in the tanks and feeding the larvae with food in the water in a larval tank. Eightly, after a period of time, brushing the spat out of the larval tank, catching the brushed-out spat on screen trays, and replacing the spat contained on such screen trays in a culturing tank of water on such screen trays being stacked vertically therein. Ninethly, periodically changing the water in the culturing tanks by inflow/outflow of water and monitoring food levels in the culturing tanks. Finally, after a preselected period of time, removing juvenile scallops from the culturing tanks.
