An analysis of logs from the 1986 4X summer purse seine fishery / by M.J. Power and R.L. Stephenson. : Fs70-8/87-77E-PDF

"Analysis of data from the second year of use of the revised 4WX purse seine logbook is presented. The overall coverage was again excellent with all active boats represented and the logbooks accounting for 91% of the landings records by Statistics Branch. Despite a 40% reduction in catches in comparison with 1985, overall effort (days fished and sets made) was reduced by only 20% and hours searched by 10%. This overall trend of reduced catch and increased relative effort resulted in generally lower CPUE for all areas. This has been attributed to the very specific roe market which dominated the fishery. The set rate per hour was higher or the same for all areas except Trinity Ledge, suggesting a problem or weakness in this important stock component"--Abstract, page 2.
