Trends in Inland Commercial Fisheries in the United States

Abstract (from AFS): Inland fisheries, defined as finfish caught in lakes, rivers, and other water bodies, provide economic value and a source of protein at local and international levels. However, no comprehensive compilation of U.S. inland commercial fisheries exists. We sought to obtain data across all 50 states during 1990–2015 and noted a small, but significant, decline in harvest. The minimum harvest averaged 41,427 tonnes during 2009–2015 and peaked in 1995 with a minimum harvest of 49,951 tonnes. During 2009–2015, harvest and taxonomic composition varied regionally: eastern interior (the highest regional harvest, dominated by coregonines and carp), western interior (carp and Clupeidae), Gulf (catfish and...

The U.S. Inland Creel and Angler Survey Catalog (CreelCat): Development, Applications, and Opportunities

Abstract (from Fisheries): Inland recreational fishing, defined as primarily leisure-driven fishing in freshwaters, is a popular pastime in the USA. State natural resource agencies endeavor to provide high-quality and sustainable fishing opportunities for anglers. Managers often use creel and other angler survey data to inform state- and waterbody-level management efforts. Despite the broad implementation of angler surveys and their importance to fisheries management at state scales, regional and national coordination among these activities is minimal, limiting data applicability for larger-scale management practices and research. Here, we introduce the U.S. Inland Creel and Angler Survey Catalog (CreelCat), a first-of-its-kind,...

The U.S. Inland Creel and Angler Survey Catalog (CreelCat) Application and CreelCatch R Package

The US Inland Creel and Angler Survey Catalog (CreelCat) application contains a web viewer which allows users to interact with the data included in the CreelCat data release. This includes the ability to view and download the data, explore data availability, develop custom summarizations, and create visualizations including maps and plots. In addition to the web application, a custom R package, CreelCatch, has been created which can be used to model relationships between angler effort and fish catch. The CreelCat database is a compilation of inland angler survey data collected and provided by fisheries management agencies from across the United States brought together in a single location by USGS. This dataset...

COVID-19 influences on US recreational angler behavior

Abstract (from PLOS ONE): Recreational angling in the United States (US) is largely a personal hobby that scales up to a multibillion-dollar economic activity. Given dramatic changes to personal decisions and behaviors resulting from the COVID-19 pandemic, we surveyed recreational anglers across the US to understand how the pandemic may have affected their fishing motivations and subsequent activities. Nearly a quarter million anglers from 10 US states were invited to participate in the survey, and almost 18,000 responded. Anglers reported numerous effects of the pandemic, including fishing access restrictions. Despite these barriers, we found that the amount of fishing in the spring of 2020 was significantly greater—by...

Fishing for Food: Quantifying Recreational Fisheries Harvest in Wisconsin Lakes

Abstract (from AFS): Recreational fisheries have high economic worth, valued at $190B globally. An important, but underappreciated, secondary value of recreational catch is its role as a source of food. This contribution is poorly understood due to difficulty in estimating recreational harvest at spatial scales beyond a single system, as traditionally estimated from individual creel surveys. Here, we address this gap using 28‐year creel surveys of ~300 Wisconsin inland lakes. We develop a statistical model of recreational harvest for individual lakes and then scale‐up to unsurveyed lakes (3,769 lakes; 73% of statewide lake surface area). We generate a statewide estimate of recreational lake harvest of ~4,200 t and...

CreelCat, a Catalog of United States Inland Creel and Angler Survey Data

The United States Inland Creel and Angler Survey Catalog (CreelCat) contains a national compilation of angler and creel survey data collected by natural resource management agencies across the United States (including Washington, D.C. and Puerto Rico). These surveys are used to help inform the management of recreational fisheries, by collecting information about anglers including what they are catching and harvesting, the amount of effort they expend, their angling preferences, and demographic information. As of May 1, 2023, CreelCat houses over 14,729 surveys from 33 states, Puerto Rico, and Washington, D.C., comprising 235 data fields across 8 tables. These tables contain 235,015 records of fish catch and harvest...
