An assessment of redfish in subarea 2 + division 3K / by Carol A. Gavaris. : Fs70-8/81-50E-PDF
"The status of the redfish stock in subarea 2 and div. 3K was evaluated using standardized catch rate data and research survey results. The catch rate series showed an apparent decline between 1977 and 1979. Among possible causes for the decline were a decline in stock biomass, a shift in the composition of the fishing fleet and/or a change in the size selection of redfish. The research surveys did not indicate any trend in the level of abundance. A preliminary cohort analysis was presented but was not used due to too few years of data available. Evidence for a change in the status of the stock was inconclusive"--Abstract.
