DFO NE Newfoundland Acoustic Array and Atlantic Cod Tagging

An extensive network comprising approximately 30 arrays of acoustic receivers (Vemco VR2/VR2W) has been deployed in nearshore waters off the NE coast of Newfoundland; the receivers are in the water throughout the year to provide continuous monitoring and data are uploaded once/twice per year depending on accessibility. Several hundred cod equipped with coded V16 and V13 pingers (including some with depth/temperature sensor tags) have been released inshore and offshore over the past 5 yrs along with >35,000 conventionally (Floy) tagged cod.

The primary purpose of the research is to investigate cod stock structure and movement patterns and estimate exploitation rates in support of assessments of the status of the cod stock in NAFO Divs 2J3KL. This is a SPERA project dataset.
