Methods for the Comparison of Timing Behavior Applied to the Pink Salmon Fisheries of Prince William Sound, Alaska
Harvest control in salmonid fisheries was examined as a problem in the formulation of regulations which restrict time and area of fishing. An ability to rigorously define and compare the form of the progression of migration across time and between harvest areas was judged fundamental to objective ha...

Harvest control in salmonid fisheries was examined as a problem in the formulation of regulations which restrict time and area of fishing. An ability to rigorously define and compare the form of the progression of migration across time and between harvest areas was judged fundamental to objective harvest decisions. Identification and evaluation of statistical methods appropriate to the comparison of empirical migratory time densities was performed. The development of the measure of central tendency (mean date) of the time density as the consistent, unbiased estimator of migratory behavior was given. Practical evidence demonstrated that the mean date was highly resistant to factors which contribute variability to the basic expression of migratory behavior. Brood year cycle and locality were treated as fixed effects in statistical analyses applied to the timing statistics of catch and spawning escapement. Fixed effects analysis of variance models were examined to analyze differences in mean dates of migration. Multiple comparison analysis, Scheffe's a priori method, correlation, and multiple regression analyses were employed to objectively define the performance of the fishery and the escapement in time and space. Highly significant differences were shown to exist between timings of odd and even populations. For each cycle year for both catch and escapement the management districts were shown to be highly distinct with respect to timing behavior.
