Evaluating stock and catchability trends: Annual average catch per unit effort is an inadequate indicator of stock and catchability trends in fisheries

By IF Wallace, RK Lindner and DD Dole

Abstract

Changes in the distribution of fishing effort over the season can influence trends in annual catch per unit effort (CPUE) because the vulnerability of the target species varies seasonally. We use annual and monthly time series analysis of CPUE data for a lobster fishery to show that time trends in CPUE are dependent upon the time interval selected. Changes in the spatial distribution of effort will almost certainly have similar consequences. Modellers and managers of fisheries need to quantify the effects of economic and regulatory changes on the temporal and spatial allocation of fishing effort.lobster catch per unit effort catchability stock estimation
