Description:"The research objective was to develop a new non-invasive, non-lethal method to assess groundfish populations and map their associated seabed habitat in the SCB. More specifically, the effort was to begin developing a survey technique that combines multi-beam sonar measurements for habitat characterization, multi-frequency echosounder measurements for mapping aggregations of rockfishes and facilitating their remote identification, and camera observations from and ROV for validation of the acoustically classified seabed and taxa and estimations of species proportions and their size distributions. Ultimately, it will be necessary to combine these types of data with measures of the biotic and abiotic environment and its effect on the dynamics of rockfish recruitment processes and the dispersion or redistribution of recruits from protected to harvested areas. Such collective knowledge will provide a basis for a longer-term and broader spatial-scale assessment of rockfish and assure the effectiveness of the protected areas in the SCB"--Objectives.
