Book excerpt: "Automated acoustic recording systems deployed on commercial fishing vessels have been used since 1997 to document the distribution and relative abundance of Atlantic Herring from industry vessel surveys and fishing excursions in the Bay of Fundy and coastal Nova Scotia area within Northwest Atlantic Fisheries Organization (NAFO) divisions 4VWX. During the years 2015 to 2017, regularly scheduled surveys at approximately 14 day intervals were again conducted on the main Herring spawning components, and the spawning stock biomass for each component was estimated by summing these results. Six structured surveys were conducted in Scots Bay in 2015, six in 2016, and eight in 2017. Five usable structured surveys were conducted on German Bank in both 2015 and 2016. There were four (plus two) surveys on German Bank in 2017. The September 17 survey was initially excluded because it was nine days after the previous one; however, this resulted in a 28-day gap before the next acceptable survey. Subesquently, at the 2018 assessment meeting, this survey was included. One acceptable structured survey was completed in the Trinity Ledge area in 2015, followed by three in 2016 and four in 2017. There were no structured surveys conducted in 2015 or 2016 for Spectacle Buoy; however, three fall surveys were completed in 2017. In most cases, these surveys provided good coverage of the spawning areas consistent with established protocols"--Abstract, page iv.
