"In September 1979, 5145 trawl-caught Dover sole (Microstomus pacificus) were tagged and released in northern Hecate Strait (Area 5D), primarily for stock delineation. Through December 1984, 745 (14.5%) were recovered. Recovery rates varied inversely with length at tagging, at fork lengths ≤ 46.5 cm rates were lower for a few adverse "conditions at release"; but were unaffected by overnight holding. Handling mortality was negligible. Maximum time at liberty is expected to be considerable, possibly as much as 14 years. Dispersion of tagged Dover sole was negligible--ca. 0.4% /annum southward. Most recoveries (98.2%) occurred on the "summering" grounds in Area 5D or the deep-water "wintering" grounds to the westward (Area 5E). Independent estimates of instantaneous total mortality rate were 0.25 (tag returns) and 0.30 (age-frequencies). Results of growth analysis, based on length-increments of tagged fish, and length-at-age (otoliths), were unsatisfactory, perhaps because of the lack of data on length-at-age of juvenile Dover sole"--Abstract, page iii.
