Monitoring tuna ranches
TAG-A-Giant descended upon Ensenada Mexico in mid-August to install an acoustic monitoring station in collaboration with Maricultura del Norte. The TAG team led by Dr. Barbara Block, Robbie Schallert, Luis Rodriguez and Dane Klinger successfully implanted twelve acoustic tags inside captured Pacific Bluefin tuna. The fish were then released back into their grow pen, where they will be monitored remotely from Stanford University's Hopkins Marine Station in Pacific Grove, CA. The internal tags measure the tuna body temperature and transmit the data to a receiver mounted on the outside of the cage. The receiver then relays the information to a satellite overhead, which downloads the information to scientists.
