Science: Fishing success not dependent on skill level

Catch inequality is a term that describes the phenomenon of a small number of anglers catching a disproportionately large number of fish.  It happens commonly in recreational fisheries but it has never been the subject of a long-term study, and not much is known about how and why it changes over time.  There have been studies that suggest catch inequality is related to catch per unit effort (CPUE).  Generally, there is low catch inequality when CPUE is high and high catch inequality when CPUE is low.  Catch inequality, therefore, reduces the usefulness of using CPUE as an indicator of fishing success and could reduce the effectiveness of management decisions.  Seekell et al. (2011) tested the hypothesis that catch inequality increases as CPUE decreases because of resource scarcity.
