Biomass estimates from Canadian research vessel surveys on the Scotian Shelf and in the Gulf of St. Lawrence from 1970 to 1979 / by P.A. Koeller.: Fs70-8/80-18E-PDF
"In 1970 a Working Group of ICNAF reviewed the logistics, design and accuracy of groundfish trawl surveys with intensions to implement coordinated and standardized surveys throughout the ICNAF area. ... In the same year the Marine Fish Division, Resource Branch, began a continuing series of stratified random trawling surveys covering most of the continental shelf within Subarea 4. Since then, these and similar surveys in other areas have become an increasingly important complement, and in some cases, an alternative to commercial fisheries statistics for assessment purposes. The 1979 cruises on the Scotian Shelf and in the southern Gulf of St. Lawrence complete ten years of annual surveys using the same ships, gear and sampling methods. The present report summarizes biomass estimates for various species and species groups during this period in ICNAF Divisions 4T, V, W and X."--Introduction, pages 1-2.
