In UK Columbia, Canada, salmon purse seiners line up at fishing access points, forming well outlined queues.
2 models were presented for exploitation rates re queuing patterns. The overflight model was fit to the line-up distributions. Read more on the topic of fly fishing.
The model fit well and the parameter estimates reflected anecdotal and statistics info about fish behavior. The exploitation rates saturated at an effort level of one hundred vessels ( while the maximum effort noted was 363 boats ) and suggested that ( at saturation ) the fleet caught 80% to ninety percent of the exposed migrating salmon present in Johnstone and Queen Charlotte Straits during what were ordinarily 48- or 72-hour fishing openings. ( Note : Salmon successfully migrating thru the strait on days that were closed to seiners and salmon that were not exposed to the gear--e. You should buy wonderful PFDs that not only look good and feel cosy but have storage pockets for holding your critical kit. The exploitation reaction to effort was qualitatively distinct from the forms incorporated in conventional models.
