This article describes established and emerging sport fisheries in the highlands of Uttarakhand (India) including for mahseer (Tor putitora), goonch (Bagarius yarrelli and B. bagarius), and brown trout (Salmo trutta fario). It also addresses as yet unrealised opportunities for establishment of...

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...

Methylmercury is a global pollutant of aquatic ecosystems, and monitoring programs need tools to predict mercury exposure of wildlife. We developed equations to estimate methylmercury exposure of piscivorous birds and sport fish using mercury concentrations in prey fish. We collected original data...

Unintentional and illegal introductions of species disrupt food webs and threaten the success of managed sport fisheries. Although many populations of Burbot Lota lota are declining in the species' native range, a nonnative population recently expanded into Flaming Gorge Reservoir (FGR),...

Sport fisheries are frequent drivers of nonnative fish introductions throughout the inland waters of North America. These fisheries often value aggressive, large-bodied predators, and although they satiate angling demand they are also potentially problematic in systems that support imperiled...

Recreational angling is a dominant use of inland fish resources. Since recreational angling is a leisure-based activity, the stock manager must meet two objectives: (1) maintain fish stocks, and (2) maximize angler satisfaction with limited catch. To achieve these goals, it is important to evaluate ...

There are often limited data available to support the sustainable management of recreational fisheries. Electronic citizen science platforms (e.g., smartphone applications) offer a cost-effective alternative to traditional survey methods - but these data must be validated. The researchers compared...

Brown Trout Salmo trutta are a popular sport fish, and numerous populations that are unable to successfully reproduce are maintained with supplemental stockings in waters with habitat that can support individual survival (e.g., appropriate thermal refuge). Long-term management of these populations...

In this paper we model recreational anglers' decisions to voluntarily release their catch to improve fish stock conservation. Using a random utility framework, we compare anglers' utility of retaining and consuming fish versus increased stock conservation achieved by fish releases. The analysis is...
