We calculated between-reader precision of ages estimated with scales and whole otoliths (sagittae) of White Crappie Pomoxis annularis for 10 Minnesota populations, and determined effects of population and mean age on precision. For all samples combin

Manual removal of non-native brown trout (Salmo trutta) led to increased abundance and improved size structure of a native brook trout (Salvelinus fontinalis) population. Reproductive dynamics of brook trout in response to release from this competito

Competition with invasive species and a warming climate have threatened brook charr (Salvelinus fontinalis) populations throughout their native range. In particular, brown trout (Salmo trutta) often displace brook charr when the two are sympatric. Br

Indices of biotic integrity (IBIs) are used to assess ecosystem health of streams and rivers. Streams and rivers with high IBI scores should support abundant and healthy populations of recreationally important sport fishes. However, the fundamental a

The Driftless Area in southeastern Minnesota is on the southwestern edge of the native range of Brook Trout Salvelinus fontinalis. It was assumed that native Brook Trout were extirpated from this region in the early 1900s due to degraded stream condi

Seasonal patterns in growth, survival and movement of brook trout Salvelinus fontinalis were monitored in two southeastern Minnesota streams divided into study reaches based on brown trout Salmo trutta abundance. We estimated survival and movement wh

Survival of stocked fish can be mediated by biotic factors such as size and species, predators, and prey, and abiotic influences such as temperature and habitat. Walleyes Sander vitreus are numerically among the most stocked fish in the USA, yet stoc

Growth rate variation of three age groups of brown trout, Salmo trutta L. (age-0, 1 and 2, and 3+), was quantified from recaptured, individually tagged brown trout and related to season, stream reach, relative abundance, initial length and movement t

We assessed recruitment, survival, emigration, and immigration of brown trout Salmo trutta in six interconnected stream reaches to quantitatively estimate how much immigrants contributed to population size in reaches in southeastern Minnesota. We als
