Sea-cage aquaculture impacts on market and berried lobster catches

Using 11 years of data collected by lobster fishers in Port Mouton Bay, Atlantic Canada, this study shows that both market-sized lobster catches and berried lobster counts in 5 different regions adjacent to a finfish farm were reduced during stocking (feed) periods compared to non-stocking (fallow) periods. Also, lobster catches were lower in region 2, which included the fish farm, and higher in region 5, which was furthest away from the farm. Our results provide critical information for the management of multiple human uses in the coastal zone and the conservation of shellfish habitats that sustain traditional fisheries.
