- Abstract
Catch-and-release angling is gaining popularity worldwide and plays an increasingly important role in both fisheries management and conservation. Mortality from catch-and-release angling is well documented across species, but the sublethal effects have not been evaluated in a natural setting. Laboratory studies have yielded mixed results regarding catch-and-release impacts on fish growth. These studies do not adequately capture the scales of stress and variability of a natural system. We used a 27-year mark-recapture study of 1050 individually tagged largemouth bass ( Micropterus salmoides) to determine the effects of catch-and-release angling on the growth in a natural setting. Individual bass were angled one to six times per season. Recapture intervals ranged from 1 to 98 days. Largemouth bass exhibited a post-release period (~6 days) of weight loss. Following this weight loss, we observed a subsequent period of compensatory growth facilitating recovery to normal weight. We found that catch-and-release angling had little impact on the overall seasonal growth patterns of largemouth bass and therefore should have limited adverse effects on growth-dependent ecological functions.
