Newfoundland and Labrador Comparative Fishing Analysis – MV Calvert

Abstract

Comparative fishing was undertaken in the spring of 2023 and 2024 between the Marine Vessel (MV) Calvert and CCGS (Canadian Coast Guard Ship) John Cabot. Estimated conversion factors are directly applicable for the sister ships CCGS John Cabot and CCGS Capt. Jacques Cartier in Northwest Atlantic Fisheries Organization (NAFO) Divisions (Div.) 3LNO in spring. Conversion factors are required for seven taxa, none of which had significant length effects. Twenty six taxa showed no significant difference in relative catchability. All other taxa had insufficient data to determine if a conversion factor is appropriate. To support community-level analyses, conversion factor analysis was completed for functional groups on an Ecosystem Production Unit scale for the Grand Bank (NAFO Div. 3LNO). No difference in catchability was found across functional groups.
