Results, through 1985, of the rock sole (Lepidopsetta bilineata) tagging experiments in Hecate Strait (British Columbia) during April-May 1982 with regard to stock delineation / by J. Fargo and S.J. Westrheim.: Fs97-4/1912E-PDF

"During April-May 1982, 10,617 rock sole (Lepidopsetta bilineata) were tagged and released in Hecate Strait, at six sites. Purposes of the study were age-validation (to be reported elsewhere) and stock delineation (this report). Recovery rates were relatively low for the major releases (0-2.3%), and poor condition of fish caught for tagging was deemed the principal cause. No recoveries were reported outside Hecate Strait. Some intermingling was noted of rock sole released in South Hecate Strait with those in North Hecate Strait, but none in the opposite direction. Maximum time at liberty among sub-experiments was relatively short--7-9 quarter-years. Estimates of instantaneous total mortality rate (Z = 1.35 - 1.61) were excessive for pleuronectids in Hecate Strait, and probably reflected the poor physical condition of the rock sole caught for tagging"--Abstract, page iii.
