The Relationship of Fishing Effort by Gill Nets to the Interval Between Lifts
A description is given of the method used in analysing data from the Great Slave Lake summer fishing by which the fishing effort exerted by gill nets that are cleared every two, three, four or five days can be made comparable with the effort exerted by gill nets that are cleared daily. A comparison...
