The 1987 report of the Johnstone Strait commercial net catch verification program / by Jim Lettic and Al Gould. : Fs97-4/2003E-PDF

"Sales receipt data from the 1987 Johnstone Strait pink and sockeye commercial net fishery were processed in-season, using microcomputers, to verify catch and to project final catch for the target and incidental species. This report, the third in a series (1985-87), summarizes the activities of the 1987 Johnstone Strait Commercial Net Catch Verification Program (JSCNCVP). Electronic data processing procedures and results are presented, and two methods of in-season catch estimation (JSCNCVP vs DFO Hails) are compared. These in-season estimates were also compared with the post-season catch estimates from the Pacific Region Catch Reporting System (PRCRS). The focus of this report is the various methods for projecting final catch from incomplete data. Emphasis is given to those variables that may affect in-season predictions of final catch. This report assesses (1) veracity in reporting, (2) the roles of PRCRS, DFO (e.g. Fishery Officers and biological management) and Industry personnel, and (3) legislation governing the reporting of catch from commercial salmon harvest"--Abstract, page iii.
