“…In rivers, sea-son, light intensity, water levels and water temperature, in particular, have been shown to influence the timing and intensity of movement (Heggenes 1988;Jonsson 1991;Garrett & Bennett 1995;Rustadbakken et al 2004).

Zimmer M, Schreer JF, Power M. Seasonal movement patterns of Credit River brown trout (Salmo trutta). Ecology of Freshwater Fish 2010: 19: 290–299. © 2010 John Wiley & Sons A/S Abstract – Movement habits in riverine populations of brown trout vary among watersheds. Thus it is important to identify factors influencing differences in individual behaviour so as to improve the information resource base available for the design of river‐specific management strategies. Such information is particularly needed in the rapidly urbanising watersheds of eastern North America where relatively little is known about anthropogenic influences on brown trout populations. In this study, we examined the influence of water temperature on brown trout behaviour in the Credit River in south‐central Ontario, Canada with respect to seasonal movement patterns. Observed patterns of movement were also correlated with variations in river discharge and habitat quality. Forty‐three radio‐tagged, adult brown trout were tracked in a confined 39.8 km portion of the Credit River from 15 May 2002 to 28 July 2003. Fish were captured in three sections of the river that differed in distance downstream and habitat quality. Fish size had little impact on movement patterns. However, there was considerable variation in seasonal movement with upstream movements to summer positions, maintenance of summer positions, downstream and often extensive movements in fall. Also observed was maintenance of winter positions and repeated upstream movements in late spring‐early summer to previously used summer positions. The elaborate movement behaviour in the Credit River population was attributed to seasonal changes in thermal habitat quality. Fish tagged in less suitable thermal habitats moved significantly more than fish from more suitable thermal habitats.

– The present authors studied the movements of resident stream brown trout, Salmo trutta L., in Valley Creek, Chester County, Pennsylvania, USA, using mark‐recapture techniques as well as radio telemetry. The novel characteristic of this study is that the entire stream was sampled during recapture, thus minimizing the possibility of bias during this portion of the analysis. The authors tagged 627 trout between June and September, 1995, and made 94.6% of recaptures in December, 1995, and 98.5% of recaptures in March, 1996, within 800 m of the initial tagging sites. They also implanted six trout with radio transmitters and made 94.6% of contacts within 800 m of the initial implantation sites. The data, which were pooled from mark‐recapture and radio telemetry studies, show that 95.5% of all recaptures and contacts were within 800 m of initial tagging sites. These results, derived from complete stream sampling, support previous studies indicating that a high percentage of resident stream salmonids remain in the same area of stream throughout the year.

“…On the West Kill, 79,098 m 2 were mapped and 0.085% (67 m 2 ) and 0.018% (14 m 2 ) were BMT by 1 and 2 C, respectively. Considering that previous studies identified cold-water refuges as areas at least 3 C colder than the surrounding water (Garrett & Bennett 1995;Ebersole et al 2001;Ebersole et al 2003a), these data strongly suggest that the Upper Schoharie and West Kill lack adequate thermal refuge. Additionally, the value of a refuge area is not only defined by its temperature relative to ambient river water, but also by its quality, size, and accessibility (Dunning et al 1992;Townsend et al 1997;Ebersole et al 2003b).…”

Water temperature is a key component of aquatic ecosystems because it plays a pivotal role in determining the suitability of stream and river habitat to most freshwater fish species. Continuous temperature loggers and airborne thermal infrared (TIR) remote sensing were used to assess temporal and spatial temperature patterns on the Upper Schoharie Creek and West Kill in the Catskill Mountains, New York, USA. Specific objectives were to characterize (1) contemporary thermal conditions, (2) temporal and spatial variations in stressful water temperatures, and (3) the availability of thermal refuges. In-stream loggers collected data from October 2010 to October 2012 and showed summer water temperatures exceeded the 1-day and 7-day thermal tolerance limits for trout survival at five of the seven study sites during both summers. Results of the 7 August 2012 TIR indicated there was little thermal refuge at the time of the flight. About 690,170 m 2 of water surface area were mapped on the Upper Schoharie, yet only 0.009% (59 m 2 ) was more than 1.0 C below the median water surface temperature (BMT) at the thalweg and no areas were more than 2.0 C BMT. On the West Kill, 79,098 m 2 were mapped and 0.085% (67 m 2 ) and 0.018% (14 m 2 ) were BMT by 1 and 2 C, respectively. These results indicate that summer temperatures in the majority of the study area are stressful for trout and may adversely affect growth and survival. Validation studies are needed to confirm the expectation that resident trout are in poor condition or absent from the downstream portion of the study area during warm-water periods.
