NOAA PIFSC Bottomfish Survey Method Intercalibration Project

Scientists from the NOAA Pacific Islands Fisheries Science Center (PIFSC), in collaboration with fishermen and scientists from the University of Hawai‛i, State of Hawai‛i DAR, and University of Miami, are currently engaged in a cooperative venture aboard the NOAA Ship OSCAR ELTON SETTE, to compare and calibrate different fishery-independent stock assessment survey methodologies in the Main Hawaiian Islands.

The current study compares 3 methodologies: active acoustics, bottom cameras, and fishing. Acousticians are conducting surveys using a Simrad EK60 split-beam sounder. At the same time, scientists from the University of Hawai‛i Department of Oceanography are deploying a baited underwater video camera system (called BotCam) from the contract vessel Huki Pono. A single BotCam unit will be deployed from the Sette on a few days to identify species and ground-truth target strength measurements from the EK60. Bottomfish fishermen (aboard the chartered fishing vessels Okalani, Naomi K, and Hokuloa) are conducting simultaneous fishing surveys. A 4th method, an autonomous underwater vehicle (AUV), will be added on a related cruise in May of 2011.

The NOAA Ship OSCAR ELTON SETTE is named for Dr. Oscar Elton Sette, the first and founding Director of the Hawai‛ian Fisheries Research Laboratory, which has since turned into NOAA PIFSC. Dr. Sette was a pioneer in the development of fisheries oceanography and, according to many fisheries scientists, is the father of modern fisheries oceanography in the United States.
