Tournament fishing has risen in popularity over the last half a century. As such, social and financial incentives combined with technological advancements are expected to drive changes in angler's capacity to exploit tournament‐eligible fish stocks, as has been observed in commercial fisheries. The aim of this study was to quantify temporal trends in angler efficiency and their ability to exploit a given fish stock relative to effort in largemouth bass fishing tournaments. A collective analysis across seven Illinois reservoirs comparing change through time in angler catch rates and relative population abundances indicated that angler efficiency has generally improved through time. For the decade from 2005 to 2015, a greater than threefold increase in the efficiency of anglers to exploit a static population of largemouth bass was estimated. Anglers have become more efficient at exploiting populations, which is likely to influence management decisions in the future, particularly in harvest‐orientated fisheries and those reliant upon fishery‐dependent surveys.

自21世纪初以来，竞争性大嘴鲈鱼比赛钓鱼者的捕鱼效率提高了

在过去的半个世纪中，比赛钓鱼越来越流行。因此，社会和经济激励措施与技术进步相结合，有望促使钓鱼者利用符合比赛条件的鱼类种群的能力发生变化，正如在商业渔业中所观察到的那样。这项研究的目的是量化钓鱼者效率的时间趋势及其相对于大口黑鲈钓鱼比赛的努力利用给定鱼类种群的能力。对七个伊利诺伊州水库进行的集体分析比较了垂钓者捕获率和相对种群数量随时间的变化，表明垂钓者效率总体上随时间提高了。从2005年到2015年的十年间，估计钓鱼者利用静态种群的大口黑鲈的效率提高了三倍以上。
