Further results of comparative fishing between the Canadian Coast Guard Ship (CGSS) Teleost and CCGS Capt Jacques Cartier/John Cabot in the Newfoundland and Labrador Region in Fall, with a focus on deep water species

Abstract

Comparative fishing has been ongoing since 2021 in the Newfoundland and Labrador Region as the multispecies survey transitions to new vessels, the Canadian Coast Guard Ship (CCGS) Capt Jacques Cartier and CCGS John Cabot. Analysis of this program was considered across two CSAS peer review meetings. Here we present results from Part II as they relate to the fall survey. Data collected in 2023, when added to previously collected data from 2021–22, were sufficient to estimate an additional seven deep water taxa conversions for the CCGS Teleost fall time series. Sixteen deep water taxa were determined to require no conversion. Additionally, following the recommendations from Part I, several taxa groupings were modified and reassessed for both the CCGS Teleost and CCGS Alfred Needler. Based on these regroupings, an additional eight conversion factors were determined for the CCGS Teleost and nine for the CCGS Alfred Needler.
