“…Burbot may select habitats with deep water; however, it is unclear if burbot preferentially select habitats for water depth or other habitat characteristics. For example, Slavík et al (2005) reported that burbot inhabited relatively shallow habitat with large substrate during daylight hours in the Ohŕe River, Czech Republic. Similarly, Dixon & Vokoun (2009) reported that depth was an important habitat characteristic in determining burbot presence, but that the importance of depth was conditional on substrate type and substrate embeddedness.…”

Burbot, Lota lota (Linnaeus), were illegally introduced into the Green River drainage, Wyoming in the 1990s. Burbot could potentially alter the food web in the Green River, thereby negatively influencing socially, economically, and ecologically important fish species. Therefore, managers of the Green River are interested in implementing a suppression program for burbot. Because of the cost associated with the removal of undesirable species, it is critical that suppression programs are as effective as possible. Unfortunately, relatively little is known about the habitat use of non-native burbot in lotic systems, severely limiting the effectiveness of any removal effort. We used hurdle models to identify habitat features influencing the presence and relative abundance of burbot. A total of 260 burbot was collected during 207 sampling events in the summer and autumn of 2013. Regardless of the season, large substrate (e.g., cobble, boulder) best predicted the presence and relative abundance of burbot. In addition, our models indicated that the occurrence of burbot was inversely related to mean current velocity. The efficient and effective removal of burbot from the Green River largely relies on an improved understanding of the influence of habitat on their distribution and relative abundance.

“…Wilding et al (2014) noted that, for several years, ecohydraulics research focused on the effects of velocity and depth on the channel habitats of fish and other aquatic species. Applications of numerous models such as IFIM have demonstrated that a stream can provide a range of velocity-depth combinations that support a wide range of species throughout their life stages (Shirvell and Dungey, 1983;Slavík et al, 2005). Previous studies have confirmed the correlation between the suitability curves characteristics and flow hydraulics, especially in relation to water depth and velocity (Davey et al, 2011;Macura et al, 2012).…”

“…Invertebrates respond to changes in flow and hydraulic changes (Mérigoux et al, 2009) but are less sensitive to morphological changes in regulated mountain streams (Holčík and Macura, 2001). Fish, however, are sensitive to morphological changes (Aparicio et al, 2011;Slavík et al, 2005). Furthermore, fish along with invertebrates are also sensitive to changes in water temperature, discharge (Lamouroux et al, 2006), and the quality of riparian vegetation (Džubáková et al, 2015).…”

Abstract:In this study, the quality of the aquatic habitats of mountain and piedmont streams was evaluated using the 'Instream Flow Incremental Methodology (IFIM)' decision-making tool. The quality of habitats was interpreted from the behaviour of bioindicators in the form of habitat suitability curves (HSCs). From 1995 until the present, 59 different reaches of 43 mountain streams in Slovakia and 3 validation reaches were evaluated, and the results analysed. The aim of this study was to generalize the parameters of the HSCs for the brown trout. The generalized curves will be useful for water management planning. It is difficult and time-consuming to take hydrometrical and ichthyological measurements at different water levels. Therefore, we developed a methodology for modifying suitability curves based on an ichthyological survey during a low flow and a flow at which fish lose the ability to resist the flow velocity. The study provides the information how such curves can be modified for a wider flow range. In summary, this study shows that generalized HSCs provide representative data that can be used to support both the design of river restoration and the assessment of the impacts of the water use or of climate change on stream habitat quality.

“…They are largely sedentary, ambush predators (Roberge et al 2002) but can have a relatively large range during feeding. There is evidence from other river systems that burbot actively move laterally in the river channel from bank to bank and vertically in the water column in their pursuit of prey that exhibit diel migration (Slavík et al 2005), but this behavior has not been confirmed in the Tanana River.…”

Hydrokinetic devices generate electricity by capturing kinetic energy from flowing water as it moves across or through a rotor, without impounding or diverting the water source. The Tanana River in Alaska, a turbid glacial system, has been selected as a pilot location to evaluate the effects of such a device on fish communities that are highly valued by subsistence, sport, and commercial users. The basic ecology and habitat use of fishes in turbid glacial systems are poorly understood; therefore it is necessary to study the species composition of the fish community and the spatial and temporal patterns of mainstem river use by these fishes to evaluate impacts of a hydrokinetic device. In this document, we provide an overview of existing knowledge of fish ecology in the Tanana River and impacts of hydrokinetic devices on fishes in other river systems. Seventeen fish species are known to inhabit the Tanana River and several may utilize the deepest and fastest section of the channel, the probable deployment location for the hydrokinetic device, as a seasonal migration corridor. Previous studies in clearwater river systems indicate that mortality and injury rates from turbine passage are low. However, the results from these studies may not apply to the Tanana River because of its distinctive physical properties. To rectify this shortcoming, a conceptual framework for a comprehensive fish ecology study is recommended to determine the impacts of hydrokinetic devices on fishes in turbid, glacial rivers.
