Grow-Out Cod Farming in Southern Labrador
The authors conducted the first cod (Gadus morhua) farming experiment in coastal Labrador. The goal was to demonstrate that grow-out of northern Atlantic cod is technically feasible in southern Labrador. Farming cod from Gilbert Bay for 83 days resulted in a 40% net increase in biomass with a food conversion ratio of 4.9:1. The proportion of fish lost due to escapement and cannibalism was 19%. The average weight gain of individual cod was 71%, a growth rate similar to cod farmed along the northeast coast of Newfoundland. Inshore cod from Labrador are smaller in size-at-age than inshore cod of northeast Newfoundland, likely due to a shorter growing season. By holding Gilbert Bay cod in a net pen within the seasonal thermocline, the growth rate of farmed fish was increased. Published in: Bulletin of the Aquaculture Assoc. of Canada 98 (2) 47-49. 1999.
