Maritimes Region snow crab trawl survey : detailed technical description / by Ben Zisserson. : Fs97-6/3128E-PDF
An annual trawl survey is conducted on the Scotian Shelf to assess the snow crab stocks in the Maritimes Region. This survey uses a modified small mesh “Nephrops” trawl to capture snow crab across their size spectrum with constant monitoring and recording of trawl dimensions through a geo-referenced trawl monitoring / mensuration system. Water temperature at depth is also recorded for each tow. A suite of electronic equipment is used to facilitate the capture of all required data and two distinct personnel teams, vessel crew and scientific staff, cooperate to perform all required tasks. The trawl catch from each tow is separated, weighed and counted by species. All crab species are examined in more detail with morphometric measurements recorded for each animal. A detailed description of all tasks, standard operating procedures and materials used throughout the course of this survey are provided within this document.
