“…Habitat suitability indices have been widely developed for fishes and other aquatic organisms (e.g., Hamilton and Nelson 1984;Raleigh et al 1986;Simon and Cooper 2014). A primary application of habitat suitability indices is to conduct instream flow modeling (Bovee 1986;Annear et al 2004).…”

Knowledge of the habitat suitability of freshwater mussels (family Unionidae) is necessary for effective decision making in conservation and management. We empirically measured microhabitat use for 10 unionid mussel species, including the U.S. federally endangered Alasmidonta heterodon, at 20 sites in the Tar River basin, North Carolina, USA. We also quantified habitat availability at each site, and calculated habitat suitability for each mussel species. The majority of available habitat across all sites consisted of shallow, slow-moving water with penetrable silt or sand substrate. Among species, mean water depth of occupied habitats ranged 0.23-0.54 m, mean bottom velocity ranged 0.001-0.055 m/s, average mean-column velocity ranged 0-0.055 m/s, and mean substrate penetrability ranged 0.11-11.67 on an index scale. The most commonly measured dominant substrate materials were silt, sand, very coarse sand, pea gravel, and coarse gravel. The most common cover types were coarse woody debris and fine woody debris. These findings revealed a relationship between the niche breadth and conservation status of four species. Federally endangered A. heterodon consistently showed a narrower suite of suitable microhabitats than the common mussel Elliptio complanata. The range of suitable habitat characteristics for Fusconaia masoni and Villosa constricta, listed as North Carolina (USA) state endangered and special concern, respectively, was typically narrower than those of E. complanata and wider than those of A. heterodon. These habitat suitability criteria and relationships will be useful to guide identification of suitable sites for habitat protection, mussel relocation, or site restoration.

“…However, it is also possible, although unlikely, that F. maletae persists at these sites and simply evaded detection during the survey. Elsewhere, local habitat variables such as substrate size, water depth, conductivity, and temperature have been shown to be important predictors of occurrence for other species of Faxonius (formerly Orconectes ) crayfish (Hamr, 2002; Simon & Cooper, 2014; Welsh & Loughman, 2015; Dyer, Mouser & Brewer, 2016). Such relationships, therefore, are likely to exist for F. maletae , despite their absence or inconclusiveness in this study, especially if the natural rarity of F. maletae limited the statistical power of the analyses.…”

“…To identify potential environmental predictors of F. maletae occurrence, environmental characteristics were measured at each survey site. Potential predictors were identified based on previous studies of crayfish habitat preferences (Hamr, 2002; Simon & Cooper, 2014; Welsh & Loughman, 2015; Dyer, Mouser & Brewer, 2016). Dominant substrate (i.e.…”

Few observations exist for the Kisatchie painted crayfish (Faxonius maletae), and little is known about its distribution, habitat use, or population structure. The lack of basic ecological data has led to a ‘Data Deficient’ designation, a category of conservation concern that is often overlooked for management actions. This work provides updated data and practical management suggestions for similarly Data Deficient species. Comprehensive (i.e. beyond known collection sites) crayfish surveys paired with habitat assessments across north‐east Texas were conducted. Among 74 survey sites in 10 counties within and adjacent to the known range for F. maletae, eight total crayfish species were encountered within 35 of these sites (47.3% of the total). Thirteen F. maletae individuals were collected across seven sites (9.5%). Notably, two individuals were found where the species had not been previously observed. Stepwise multiple logistic regression indicated that conductivity and availability of exposed root masses were positively related to F. maletae presence, although neither factor was statistically significant on its own. Neither nonmetric multidimensional scaling nor canonical correspondence analysis identified patterns between F. maletae presence and the presence of other crayfish species. Overall, F. maletae is geographically rare and occurs in exceptionally low abundance, challenging the ability to understand drivers of its distribution. However, given the depth of this survey, we can confidently say that F. maletae is no longer Data Deficient; rather, there is compelling evidence that it has a limited range and small population size. The Data Deficient versus rarity debate has wide‐reaching impacts on the conservation of aquatic taxa; species that are Data Deficient require heightened research focus in general, whereas rare organisms require targeted management to protect specific habitats. Furthermore, we suggest that future management efforts should focus on maintaining current populations through active monitoring to inform the potential habitat suitability of new areas for protection.

“…Instream hydraulics is one of the important components that affect the aquatic environment. One of the approaches to quantify fish habitat is to relate the instream hydraulics with habitat suitability index (HSI) (Edwards et al 1983;Raleigh et al 1986;Simon and Cooper 2014;Heath et al 2015). The habitat suitability index varies with hydraulics and other physical and environmental factors.…”

Dam-lake Operation to Optimize Fish Habitat

2015

The existence of dams cannot be ignored. The dam-lake formed due to the construction of a dam can be considered an integrated part of the natural watershed. A question which must be answered is how to operate a dam-lake so that the negative impacts of the dam on the natural flow system are reduced and at the same time the intended purposes of the dam are efficiently met. Among many aquatic species, the fish species are probably the most highly impacted species by the construction of a dam. As a result of the dam, fish habitat can decrease resulting in low productivity to no productivity at all for some fish species. This paper presents a methodology to develop a dam-lake operation model to maximize fish habitat. This study considered the physical habitat of smallmouth bass in its adult life. The operation model is developed by linking one-dimensional hydraulics model HEC-2 and dam-lake simulation model HEC-5 with a meta-heuristic optimization algorithm, the Shuffled Frog Leaping Algorithm (SFLA). The computation of physical habitat, which is a function of habitat suitability index and some hydraulic parameters, is coded within the optimization algorithm. The model has been successfully applied to an unnamed dam-lake in the northeast of the U.S. The fish habitat for smallmouth bass in its adult life stage increases as the water surface in the dam-lake increases. Some recommendations to improve the model are discussed in the conclusions section.
