By J.-F. Landry, M. Moriyasu, E. Wade, and M. Hébert
Abstract
This document summarizes the details of the 2013 snow crab bottom trawl survey of the southern Gulf of St. Lawrence. The primary objective of the survey is to provide the data on abundance and distribution of snow crab and other by-catch species. The survey was conducted from July 9 to October 14, 2013 using a new chartered commercial fishing vessel, the “Jean Mathieu”. A total of 355 stations were trawled and 352 stations were successfully completed. This year two major changes in protocol were made. First, the net monitoring system has been totally changed from ‘Netmind®’ to compatible ‘e-Sonor®’ system. Second, the total number of stations was increased from 325 in 2012 to 355. Details on the survey protocols, timing of the survey, the characteristics of the individual trawl tow, and summary of snow crab catches and catches of others species are provided.
