Use of a mixed-species yield-per-recruit model to explore the consequences of various management policies for the Oregon flatfish fishery

Three types of management policies are considered: maximization of output, efficiency-oriented, and a minimum trawl cod-end mesh size regulation with no restriction of effort. If an efficiency-oriented policy were adopted, the current minimum mesh size regulation of 114 mm would be optimal, but its effort is left unrestricted, or it a maximization strategy were adopted, a larger mesh size would result in greater volume yields. Optimal mesh size is more sensitive to the management policy selected than it is to either variations in recruitment or to costs associated with fishing. -from Author
