Tagged Fish Id (TEXT) Acoustic transmitter ID codes assigned by the tag manufacturer (Vemco). Each acoustic transmitter was surgically implanted into an individual sevengill shark. See the 'Sevengill Shark Tag Catch' file for associated information on shark size and sex, as well as tagging date and tag life. Date (DATE) (Vemco V13-1L acoustic coded transmitters, 69 kHz, 6 g in water, estimated battery life ~3 20 days; Vemco-Amirix Systems Inc., Halifax, NS) and released in Little Bay (approximately 17 km from the coast in 2007 and 18 km away in 2008, Figs. 1 and 3). The tagging process took ~ 15 min and tagged lobsters were placed into a lobster trap Approach: To accomplish these objectives, we are using acoustic telemetry with multi-sensor (depth and accelerometry) acoustic transmitter tags (Vemco©). These tags allow us to infer the post-release fate of fish from behavior: alive, dead from predation, dead, or emigration from the reef. Posts about North Carolina Court of Appeals written by Matthew L.M. Fletcher (VH110) to relocate ultrasonic tags. Attempts to relocate fish by radio tags will be done using a scanning receiver (ATS R410) and a 3-element Yagi antenna. Radio tracking will be done in conjunction with the ultrasonic tracking. Fish will be manually tracked on a weekly or bi-weekly basis.
biologging devices. He was the lead scientist on the first large-scale deployment of electronic tags on marine fish (European plaice) in 1993, which demonstrated the facultative use of tides for migration and has lead to a number of other significant findings, such as spawning site fidelity and new perspectives on fish stock structure.

Fish were measured, sexed and a 1 3 cm Peterson disc tag was fitted to the proximal margin of the pectoral fin. An acoustic transmitter (V8SC-6L, 9 mm diameter 20 mm, frequencies: 67 3–75 0 kHz, continuous pulse rate 1000–2000 ms, Vemco Ltd, Shad Bay, Nova Scotia,
