An analysis of the perceived impact of mussel aquaculture on catch per unit effort (CPUE) for the seasonal lobster fishery on the Northeast coast of Newfoundland

PARR-2017-NL-07

Description

Over the past two decades lobster harvesters have noted an apparent decline in lobster catch rates on the northeast coast of Newfoundland (Lobster Fishing Areas (LFAs) 4A and 4B). This has been particularly evident in the western section of Notre Dame Bay and Green Bay where mussel aquaculture is prevalent. This analysis project will use a combination of recent and historical data for lobster annual catch statistics to determine whether there is a difference in lobster CPUE (catch per unit effort) in bays with active mussel aquaculture leases as compared to those without. This will be the first comprehensive analysis of the interaction between lobster abundance and mussel aquaculture in the region.
