October 2022- In September, we embarked on a field expedition to re-initiate FAD and acoustic reseach among the FADs deployed off San Juan, Puerto Rico. In this effort, our goals are to better describe fish movements relative to the FADs; fishing trip success and catch and effort; how FAD design can affect species abundance, presence, and biomass; and the impact that FADs have on local businesses and visitors to Puerto Rico. Watch the video above or click here to learn about our recent field expedition off San Juan, PR, in September, where we re-initiated acoustic, camera, and tagging work whereby 4 dolphinfish, 2 yellowfin tuna, and a silky shark were tagged and released with acoustic transmitters. We also redeployed sound hydrophones, temperature instruments, and monitoring cameras. We intend to share updates on data collected from this work in our next newsletter due out in December.
Past Updates – Fish Movements
2019 – Since 2015, we have deployed 12 acoustic V16TP tags on ten dolphinfish, a wahoo, and a blackfin tuna around the FADs. In addition, 547 plastic dart tags have been deployed on dolphinfish (539), wahoo (6), a blackfin tuna (1), and a silky shark. Plus, a total of 12 satellite tags were deployed on dolphinfish (10), a wahoo, and a silky shark. This included 2 high-rate Microwave Telemetry X-Tags and 10 Wildlife Computers mrPAT tags. Below are some figures based on data acquired and collected through June 2019.
