Survey (2007) of Rockfishes in the Southern Calibornia Bight Using the Collaborative Optical-Acoustic Survey Technique.

摘要

This report documents a second, refined COAST survey of rockfishes throughout the SCB. The 2007 COAST survey was conducted in four legs, each approximately 15 days in duration: Leg I, 8/26-9/9; Leg II, 9/13-9/27; Leg III, 10/1-10/15; and Leg IV, 10/19- 10/31. Ultimately, it will be necessary to combine the repeated estimates of rockfish distributions and abundances in the SCB with measures of the dynamics and environmental influences 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.
