An evaluation of the western Newfoundland herring acoustic abundance index from 1989-1997 / by I.H. McQuinn and L. Lefebvre.: Fs70-1/1999-120E-PDF
Since 1989, the Laurentian Region of Fisheries and Oceans has conducted six hydroacoustic surveys of herring along the west coast of Newfoundland (NAFO division 4R). The objective of this series of surveys is to develop a fishery-independent index of stock abundance for these herring stocks. This document summarises the results of the 1997 survey and compares the results with the time series since 1991. The hydroacoustic work for this latest survey was conducted aboard the CSS Frederick G. Creed from October 15 to October 31. In addition, several vessels from the west coast large purse seine fleet were directly implicated in the collection of oceanographic and biological data.
