Fishing for Atlantic cod (Gadus morhua) with pots and gillnets: A catch comparison study along the southeast coast of Labrador
Gillnets are the primary fishing gear used to catch Atlantic cod (Gadus morhua) in coastal areas of Newfoundland and Labrador but are known to catch non-target species and produce lower quality fish than live-catch methods. The purpose of this study was to compare the catch efficiency of collapsible...
