Service Description: The Fisheries and Oceans Canada (DFO) ecosystem surveys consist of research vessel survey data collected to monitor the distribution and abundance of fish and invertebrates throughout the Scotian Shelf, Bay of Fundy and Georges Bank. The surveys follow a stratified random sampling design, and include sampling of fish and invertebrates using a bottom otter trawl. These survey data are the primary data source for monitoring trends in species distribution, abundance, and biological condition within the region, and also provide data to the Atlantic Zonal Monitoring Program (AZMP) for monitoring hydrographic variability. “Summer” cruises focus on the Scotian Shelf and Bay of Fundy (i.e. 4VWX), while “Spring” cruises focus on Georges Bank (i.e. 5Z)
Collected data includes total catch in numbers and weights by species. Length frequency data is available for most species, as are the age, sex, weight and maturity information for a subset of the individual animals. Other data such as ageing material, genetic material, and stomach contents are often also collected, but are stored elsewhere.
This specific record contains a version of the ecosystem survey data which has been modified from its original format to facilitate ingestion by the Ocean ADAPT web tool (https://oceanadapt.rutgers.edu). Specifically, the ADAPT service has been limited to those species that have been reliably identified and recorded throughout the data series (n=63), and the provided numbers and weights have been standardized to account for tow distances varying from a standard tow of 1.75NM. No data from individual animals is included in this record (e.g. length, weight, age. maturity, sex, etc).
Monitoring Program Element:Lower Trophic Levels - Benthic Invertebrates, shrimp and squid Higher Trophic Levels - Fish Physical/Chemical Environment - Hydrographic data (depth, temperature, salinity) AZMP sampling conducted since 1999
