Governments responded to the Covid-19 pandemic with different policies to curtail the spread of the virus. We show how sportfishing levels are related to the stringency of Covid-19 policies. Specifically, we relate the total number of resident sportfishing trips taken each month in each of 16 U.S. states to a state-level index of COVID policy stringency. We model the number of recreational fishing trips taken in each state-month using a fixed effect Poisson regression model with state-specific seasonality and time trends. We estimate separate models for different fishing modes, and find that for fishing trips taken on private boats the number of trips may have increased by approximately 20% at moderate levels of stringency, while at high levels of stringency like those experienced in many states in March and April of 2020, trips may have stayed constant or declined by 10-20%. Similar inverse-U shaped relationships between trips and stringency are found for fishing trips from the shore and from charter boats.
各国政府针对新冠疫情采取了不同政策以遏制病毒传播。我们展示了休闲钓鱼活动水平与新冠疫情政策的严格程度之间的关系。具体而言，我们将美国16个州中每个州每月的居民休闲钓鱼出行总数与一个州级别的新冠政策严格指数相关联。我们使用具有州特定季节性和时间趋势的固定效应泊松回归模型，对每个州每月的休闲钓鱼出行次数进行建模。我们针对不同的钓鱼方式估计了单独的模型，发现对于乘坐私人船只进行的钓鱼出行，在适度严格程度下出行次数可能增加了约20%，而在像2020年3月和4月许多州所经历的高度严格程度下，出行次数可能保持不变或下降了10 - 20%。对于从岸边和包租船上进行的钓鱼出行，出行次数与严格程度之间也发现了类似的倒U形关系。
