Comparison of fishery-independent methods for sampling Main Hawaiian Islands Bottomfish assemblages (SE1102L1, EK60)
Optical, active acoustics, and research fishing data on bottomfish abundance and biomass
were collected over predetermined grids to compare results of methodologies. Optical
data were collected using a baited stationary Botcam. Acoustics data were collected
using a narrow-beam EK60 system operating at 38, 70, and 120 kHz frequencies. Research
fishing was conducted using hook-and-line on small boats. Botcam drops with simultaneous
acoustic recordings were conducted to obtain target strength measurements of fish
with known species and sizes. Bottomfishing off the Sette were conducted simultaneously
with acoustics data collection to further groundtruth the acoustics data.

Purpose | The scientific objective of this cruise is to collect data on economically important Hawaii semi-demersal fish abundance and biomass using three methodologies: optical, experimental fishing, and active acoustics. Based on the results, a subset of methodologies, or a single methodology will be selected to provide the best possible estimates of abundance and biomass to be applied to stock assessment models. |
