“…Because largemouth bass feed at a higher trophic level than either of the 2 sunfish species, the relatively lower Se concentrations in this species may suggest that biomagnification is not occurring at the Kingston spill site; however, the lower Se concentrations in largemouth bass also could be attributable to differences in exposure conditions. Although sunfish tend to be relatively sedentary, the home range of largemouth bass can be greater than 10 hectares —large enough for these fish to move back and forth between heavily impacted and less impacted areas at the Kingston site. The difference in Se concentrations between fish collected in ash‐affected and reference locations was also smallest for largemouth bass.…”

In December 2008, 4.1 million cubic meters of coal ash were released into the Emory and Clinch Rivers by the Tennessee Valley Authority Kingston Fossil Plant. Coal ash contains several contaminants, including the bioaccumulative metalloid selenium (Se). Because Se is predominantly accumulated in aquatic organisms through dietary rather than aqueous exposure, tissue-based toxicity thresholds for Se are currently being considered. The proposed threshold concentrations range between 4 μg/g and 9 μg/g Se (dry wt.) in whole body fish, with a proposed fillet threshold of 11.8 μg/g. In the present study, the authors examined the spatial and temporal trends in Se bioaccumulation and examined the relationship between the Se content in fillets and in whole bodies of fish collected around the Kingston spill site to determine whether Se bioaccumulation was a significant concern at the ash spill site. Whereas Se concentrations in fish (whole bodies and fillets) were elevated at sampling locations affected by the Kingston ash spill relative to reference locations, concentrations do not appear to be above risk thresholds and have not been increasing over the 5-yr period since the spill. These findings are not only relevant to guiding the human health and ecological risk assessments at the Kingston ash spill site, but because of current national discussions on appropriate guidelines for Se in fish as well for the disposal of coal combustion wastes, the results are also relevant to the general understanding of Se bioaccumulation in contaminated water bodies.

“…Temperature, like DO, is a major determinant of fish distribution and behaviour (Carter, Weber, Dettmers, & Wahl, 2012;Hanson, Hasler, Cooke, Suski, & Philipp, 2008;Kramer & Smith, 1962).

“…In stratified lakes, differences in temperature are often observed above and below the thermocline. Temperature, like DO, is a major determinant of fish distribution and behaviour (Carter, Weber, Dettmers, & Wahl, 2012;Hanson, Hasler, Cooke, Suski, & Philipp, 2008;Kramer & Smith, 1962). Intra-seasonal temperature fluctuations in aquatic systems elicit vertical and horizontal migration by fish seeking to maximise their energetic intake and growth by experiencing various optimal thermal regions (Wurtsbaugh & Neverman, 1988).…”

Summer stratification often leads to large areas of hypolimnetic hypoxia in lakes and reservoirs. These areas of hypoxia alter fish behaviours and distributions as well as restrict access to valuable prey resources, yet few studies have examined foraging behaviour of fish in response to low dissolved oxygen (DO) concentrations. We observed foraging behaviour of juvenile largemouth bass, Micropterus salmoides, in response to varying DO concentrations in tanks that simulated a stratified lake water column during the summer: 28°C oxygenated epilimnion, 15°C deoxygenated hypolimnion. Compared with saturated concentrations (8.0-9.0 mg/L), hypolimnetic oxygen concentrations of 3.0 mg/L and 1.5 mg/L resulted in a drastic decrease in prey consumption, handling efficiency and time spent below the thermocline mainly due to avoidance behaviour of hypoxic conditions. However, we found at high hypolimnetic prey densities, individual fish were more willing to venture into reduced oxygen concentrations. Several unique behaviours including transporting prey above the oxycline for consumption, aquatic surface respiration and gill flaring were employed by largemouth bass foraging in low oxygen environments. Reduced hypolimnetic oxygen concentrations may influence and alter feeding strategies, especially for fish that rely on benthic prey resources.

“…Movement of smallmouth bass to overwintering habitats is known to occur when water temperature fell to 15–16 °C (Webster ; Paragamian ) or below 18.5 °C (Carter et al. ).

“…The exact time of movement may be modified by physical cues related to rainfall and discharge events as demonstrated by the movement of fish out of thermal refuge both before and after the observed vernal equilibrium date of March 14th. Movement of smallmouth bass to overwintering habitats is known to occur when water temperature fell to 15-16°C (Webster 1954;Paragamian 1981) or below 18.5°C (Carter et al 2012).

Smallmouth bass in thermally heterogeneous streams may behaviourally thermoregulate during the cold period (i.e., groundwater temperature greater than river water temperature) by inhabiting warm areas in the stream that result from high groundwater influence or springs. Our objectives were to determine movement of smallmouth bass (Micropterus dolomieu) that use thermal refuge and project differences in growth and consumption among smallmouth bass exhibiting different thermal‐use patterns. We implanted radio transmitters in 29 smallmouth bass captured in Alley Spring on the Jacks Fork River, Missouri, USA, during the winter of 2012. Additionally, temperature archival tags were implanted in a subset of nine fish. Fish were tracked using radio telemetry monthly from January 2012 through January of 2013. The greatest upstream movement was 42.5 km, and the greatest downstream movement was 22.2 km. Most radio tagged fish (69%) departed Alley Spring when daily maximum river water temperature first exceeded that of the spring (14 °C) and during increased river discharge. Bioenergetic modelling predicted that a 350 g migrating smallmouth bass that used cold‐period thermal refuge would grow 16% slower at the same consumption level as a fish that did not seek thermal refuge. Contrary to the bioenergetics models, extrapolation of growth scope results suggested migrating fish grow 29% more than fish using areas of stream with little groundwater influence. Our results contradict previous findings that smallmouth bass are relatively sedentary, provide information about potential cues for migratory behaviour, and give insight to managers regarding use and growth of smallmouth bass in thermally heterogeneous river systems.
