Site Description

Little Rock Lake South (45°59′44.69”N, 89°42′12.76”W) is an 8 ha, oligotrophic, seepage lake in Vilas County, Wisconsin that has no lakeshore residential development (Sass et al., 2006). Little Rock Lake South was isolated from Little Rock Lake North (10 ha).

Local people (e.g., individuals, communities, co-operatives)
National external (individual, groups. e.g., hunters, anglers, photographers, tourists)
Is the use part of a strategy to generate conservation incentives, to finance conservation, or to improve tolerance/stewardship?
Unknown/not recorded
Is there evidence that the use is affecting the conservation status of the species? HIDE
Yes – use is improving the status (e.g., population is increasing or stabilising, extraction effort OR catch per unit effort is decreasing or stable)
Is there evidence that the use is affecting natural selection?
Unknown/not recorded
Is there evidence that the use is affecting poaching of illegal wildlife trade?
Unknown/not reported

Our results in- dicate that a catch-and-release policy (and/or increasing rates of vo- luntary release; Allen et al., 2008; Gaeta et al., 2013; Isermann et al., 2013; Hansen et al., 2015) will likely result in increased abundances of LMB, but decreases in the size-structure of the populations and sub- sequent trophy fish potential

Is there any evidence that this use of the species is having a knock-on effect on the status of non-target species
Unknown/not recorded
Unknown/not recorded
Details of assessment carried out

Our results suggest that catch-and-release fishing had minimal negative effects on the sustainability of an LMB population if greater abundances are desired. However, density-dependent compensatory responses in size-structure and growth may be expected over time.
