Testing a 3-axis accelerometer acoustic transmitter (AccelTag) on the Lusitanian toadfish

摘要: Abstract A consortium composed of Thelma Biotel and Center Oceanography developed tested an acoustic 3-axis accelerometer transmitter. The first testing phase took place in experimental tanks consisted externally attaching prototype data logging tags Lusitanian toadfish ( Halobatrachus didactylus Bloch & Schneider, 1801) comparing raw logged with observed behaviours to obtain characteristic patterns that could be assigned those typical movements. Four behavioural “signatures” were considered, two different burrowing movements, attack towards a prey general activity. second was the development integrated software capable identifying patterns, process information transmit relevant acoustically. Burrowing movements activity detected transmitted 100% accuracy while attacks 61% successful rate. third Mira estuary (SW Portugal) 2 groups (five six individuals each) free living test codified signal transfer from AccelTag receiver array. novelty is has measuring capabilities archival tag but without necessity recapture tagged fish, since it ability analysing data, extract very detailed species dependent processed data.
