Data summary and review of the PHMA hard bottom longline survey in British Columbia after the first 10 years (2006-2016) / Beau Doherty, Ashleen J. Benson, and Sean P. Cox.: Fs97-6/3276E-PDF

"The Pacific Halibut Management Association of BC (PHMA) longline survey was initiated in 2006 to improve information for stock assessment of data-limited inshore rockfish species in the 'outside' management unit of British Columbia. The PHMA survey was initially designed to provide indices of abundance for Yelloweye Rockfish (Sebastes ruberrimus) and Quillback Rockfish (Sebastes maliger); however, in recent years has been used in other groundfish assessments and for monitoring the Yelloweye rebuilding plan. Due to the growing interest in the PHMA survey, it is important to establish performance criteria for the original survey objectives and emerging uses. This report is divided into 2 parts: (1) a data reporting section that includes a summary of survey objectives, design, and trends in survey indices for 2006-2016, and (2) a review of the survey performance (i.e., sampling frame, stratification, sampling allocation, power analysis, survey precision) for Yelloweye and Quillback rockfishes"--Abstract, page iii.
