Fishing in streams and rivers is a popular outdoor recreation activity in eastern Oklahoma, where most anglers target black bass (Micropterus) species. Since the early 1990s, when the last assessment of black bass fishing in the region was conducted, broadscale factors such as harvesting behavior, state fishery regulations, and bass population dynamics have changed. In 2018, we conducted creel and fish tagging surveys in three tributaries of Lake Tenkiller (Caney Creek, Baron Fork, and Illinois River) that differed in size and accessibility to provide current estimates of catch, harvest, and effort directed toward black bass. We then related these estimates to angler socioeconomic characteristics. The amount of angler effort was concomitant with stream size and accessibility, being greatest in the largest stream with the most access (Illinois River). However, catch rates were highest in the medium-sized stream (Baron Fork). Harvest rates and exploitation were near zero in all systems. Anglers fishing Caney Creek, the smallest and least accessible stream, were nearly all local, coming from zip codes ~42 km away, with low median household incomes compared to anglers at the other streams who came from a broader array of more distant zip codes and had higher median household incomes. Anglers fishing the smallest stream were also more interested in harvesting fish and having higher creel limits than anglers at the other two systems. In the Oklahoma Ozark Highlands, stream size and accessibility appear to be a significant factor in angler demographics, potentially necessitating different management strategies.

俄克拉荷马州奥扎克高地溪流中溪流大小和可达性对黑鲈垂钓者特征的影响

在俄克拉荷马州东部，在溪流和河流中钓鱼是一项流行的户外休闲活动，大多数垂钓者的目标是黑鲈（Micropterus） 物种。自 1990 年代初对该地区黑鲈鱼捕捞进行最后一次评估以来，捕捞行为、国家渔业法规和鲈鱼种群动态等广泛因素发生了变化。2018 年，我们在大小和可达性不同的 Tenkiller 湖的三个支流（Caney Creek、Baron Fork 和 Illinois River）中进行了筒子架和鱼类标记调查，以提供当前针对黑鲈的捕获量、收获量和努力量的估计。然后我们将这些估计与垂钓者的社会经济特征联系起来。垂钓者的努力程度与河流大小和可达性相伴而生，在拥有最多可达性的最大河流（伊利诺伊河）中最大。然而，中型河流（Baron Fork）的捕获率最高。所有系统的收获率和开发率都接近于零。在最小和最难到达的溪流 Caney Creek 钓鱼的垂钓者几乎都是本地人，来自大约 42 公里以外的邮政编码，与来自其他更远邮政编码和更广泛范围的其他溪流的垂钓者相比，家庭收入中位数较低家庭收入中位数较高。与其他两个系统中的垂钓者相比，在最小溪流中垂钓的垂钓者也对收获鱼类更感兴趣，并且具有更高的筒架限制。在俄克拉荷马州奥扎克高地，溪流大小和可达性似乎是垂钓者人口统计的重要因素，可能需要不同的管理策略。与其他溪流的垂钓者相比，他们的家庭收入中位数较低，他们来自更远的邮政编码范围更广，家庭收入中位数更高。与其他两个系统中的垂钓者相比，在最小溪流中垂钓的垂钓者也对收获鱼类更感兴趣，并且具有更高的筒架限制。在俄克拉荷马州奥扎克高地，溪流大小和可达性似乎是垂钓者人口统计的重要因素，可能需要不同的管理策略。与其他溪流的垂钓者相比，他们的家庭收入中位数较低，他们来自更远的邮政编码范围更广，家庭收入中位数更高。与其他两个系统中的垂钓者相比，在最小溪流中垂钓的垂钓者也对收获鱼类更感兴趣，并且具有更高的筒架限制。在俄克拉荷马州奥扎克高地，溪流大小和可达性似乎是垂钓者人口统计的重要因素，可能需要不同的管理策略。
