Variance components in the estimation of potential egg deposition of sockey salmon escapements
Mathisen OA and Gunnerod T. 1969. Variance components in the estimation of potential egg deposition of sockey salmon escapements. Journal Fisheries Research Board of Canada. 26(3):655-670
The magnitude of the variance components in the estimation of the potential egg deposition of sockeye salmon escapements to the Kvichak District, Bristol Bay, Alaska, was determined from data collected from 1957 to 1966. The greatest variance component was caused by estimation of the escapement followed by the variance due to estimation of the ratio of females in the escapement. Estimation of the average fecundity added the least variance.
