FRB Technical Reports are research documents that are of sufficient importance to be preserved, but which for some reason are not appropriate for scientific publication.

The objective of this study has been to assemble the data available concerning the scale characteristics of sockeye salmon spawning in a series of isolated locations within the Skeena River system (1945-1966), with a view to their possible use in describing...

In the Nass River watershed, juvenile and adult steelhead scales were collected to summarize the mean smolt ages for major summer and winter steelhead populations, and to investigate the lack of the first-year annulus formation which results in under-aging...

Scales of 4 and 5 year-old Skeena River and 4 year-old Fraser River sockeye of the 1963 brood year were examined for the incidence of regenerated scales. For the Skeena and Fraser 4 year-old sockeye the incidence of regenerated scales was 11.1% and 8.2%,...

The purpose of this report is to compare the incidence of circuli formed after the annulus (Fig. 1) (referred to here as "new growth") on the scales of early migrants with that on scales of the late migrants for the years 1958 to 1965.
