对收集休闲渔业数据的应用程序越来越感兴趣，这要求评估自我报告的数据与其他渔业数据之间的关系，并评估潜在的偏差。这项研究将手机应用程序和钓鱼者网站（MyCatch）的结果与三种类型的渔业调查的结果进行了比较--1次省级邮件调查、2次筒子架调查和17次刺网调查。结果表明，一个应用程序和网站可以（i）招募用户，具有广泛的空间分布，这是类似于传统的调查，（ii）生成的数据，捕捉区域捕鱼模式（2218旅行289个湖泊和90溪流或河流），和（iii）提供捕捞率估计是类似于那些从其他鱼类依赖的调查。应用程序用户的一些潜在偏见（例如，城市偏见）和省级捕捞物种的相对组成进行了鉴定。该应用程序不是估计鱼类丰度和相对群落组成的合适工具。我们的研究展示了应用程序如何能够或不能为休闲渔业监测提供补充数据收集工具，但需要进一步的研究来确定我们的研究结果对其他渔业环境的适用性。
Growing interest in apps to collect recreational -fisheries data requires that relationships between self-reported data and other fisheries data are evaluated, and that potential biases are assessed. This study compared results from a mobile-phone application and website for anglers (MyCatch) to results from three types of fisheries surveys - 1 provincial-level mail survey, 2 creel, and 17 gillnet surveys. Results suggest that an app and website can (i) recruit users that have a broad spatial distribution that is similar to conventional surveys, (ii) generate data that capture regional fishing patterns (2218 trips on 289 lakes and 90 streams or rivers), and (iii) provide catch rate estimates that are similar to those from other fisheries-dependent surveys. Some potential biases in app users (e.g., urban bias) and in the relative composition of species caught provincially were identified. The app was not a suitable tool for estimating fish abundance and relative community composition. Our study demonstrates how apps can or cannot provide a complementary data-collection tool for recreational-fisheries monitoring, but further research is needed to determine the applicability of our findings to other fisheries contexts.
