Mercury (Hg) is a concerning contaminant due to its widespread distribution and tendency to accumulate to harmful concentrations in biota. We used a machine learning approach called random forest (RF) to test for different predictors of Hg concentrations in three species of Colorado reservoir sport ...

Altering food web structure has been shown to influence mercury (Hg) concentrations in sport fish. Here, we describe a whole-system manipulation designed to assess the effectiveness of stocking relatively high-quality, low-Hg prey (rainbow trout, Oncorhynchus mykiss) as a means of increasing...

We studied long-term trends in catches per unit effort (CPUE; fish h^-1) of four sport fish taxa in the Flathead River, Montana, following changes in hydroelectric operations at the Sliš Ksanka QispProject (SKQP; formerly Kerr Dam). Prior to 1997 SKQP operations caused frequent, unnatural flow...

Catch-and-release sport angling for large-bodied fishes is a popular recreational pastime, but is also a major introduction source of invasive fishes that can impact native biodiversity. Introductions of large non-native fishes are often part of fisheries management practices to diversify angler...

Stocking and electrofishing occurrence and abundance data for northern pike Esoxlucius L. in >3800 km of French rivers across 7 years were compared to assess the effect of recreational fisheries stocking programmes on wild pike populations. A positive relationship was found between the additive...

A freshwater protected area is a designated portion of inland water that limits human activity. They were created to combat the decline of the world's flora and fauna. Some authors question their practical effectiveness in protecting endangered plant and animal species. We assessed the impact of...

Freshwater protected areas are designated parts of the inland waters that restrict human activities. They were created as a mechanism to combat the decline of fauna and flora of the world. Some authors have questioned their actual effectiveness in terms of the purpose of protecting endangered fauna ...

The optimal terminal gear in hook-and-line recreational fishing maximizes landing rates and minimizes injury to the fish because some fish will be released after capture. We designed a novel rig configuration in artificial lure fishing for top predators and examined its effectiveness in angling for ...

We compared relative abundances, average weights, and growth rates of 6 game fish species before and after the 1999-2001 partial dredging of Lake Winona, a eutrophic, urban lake in Minnesota, to determine whether lake dredging sustainably changed fish population structure to the benefit of anglers. ...

Serological assays were conducted for anti-viral hemorrhagic septicemia virus (VHSV) antibodies in four species of fish in Wisconsin (Bluegill Lepomis macrochirus, Brown Trout Salmo trutta, Northern Pike Esox lucius, and Walleye Sander vitreus) to examine spatial and temporal distributions of...
