Atlantic Cooperative Telemetry Network
• Loose network of researchers– East coast - Florida – Maine
• Organic/ground-up approach• Means to connect researchers and facilitate data
exchange• Houses a list of acoustic transmitter codes and
associated researchers– Members upload “orphan codes” – Owners of orphan codes can then contact
researchers that detected their codes to share data
Atlantic Cooperative Telemetry Network
• Developed with sturgeon as a model– Once finalized opened up for other species
• Members surveyed to determine existing assets
• 97% of researchers are using VEMCO equipment
• ACT currently funded through June 2014– NOAA NMFS Office of Protected resources

Receiver Arrays
Receiver Arrays
Lessons Learned • Majority of acoustic arrays are located in rivers,
estuaries and nearshore coastal environments• Strategic placement of assets needed– Receivers – Listening platforms – Tags
• Tagged fish have effects outside projects scope of work– Striped bass on Atlantic sturgeon spawning grounds
Concerns• Arrays are maintained on a project specifics
basis• Lack of stable funding to support existing
assets – Continued deployment– Maintenance/downloading
• Duplicated tag codes do exist and are difficult to identify– LOTEK transmitter in Atlantic sturgeon duplicated
