“…A wide range of potential sources of fine sediment inputs to rivers have previously been described, including agricultural land (Lenat, ; Lenat and Crawford, ; Harding et al , ; Nerbonne and Vondracek, ; Schriever et al , ; Johannsen and Armitage, ), urban environments (Carter et al , ; Taylor and Owens, ), deforested/clear‐cut land (Michaelis, ; Mackenzie, ), road construction activities (Extence, ; Cline et al , ; Hendrick et al , ) and mineral extraction (Weber and Post, ; Quinn et al , 1992; Hayer and Irwin, ). Fine sediment may also accumulate in rivers as a consequence of bank erosion (Nuttall, ; Dunne et al , ; Herlihy et al , ; Stott, ), habitat modification (Imhof et al , ; Dunbar et al , , Dunbar et al , ), or as a result of low flows (Extence, ; Wright and Berrie, ; Wood et al , ), which may in turn be linked to impoundments and river regulation (Boon, ; Petts, ; Doyle et al , ).…”

Increased fine sediment deposition and entrainment in rivers can arise from a combination of factors including low flows, habitat modification and excessive sediment delivery from the catchment. Physical and visual methods have traditionally been used to quantify the volume of deposited fine sediment (<2 mm in size), but here we propose an alternative, the development and utilization of a sediment‐sensitive macro‐invertebrate metric (PSI — Proportion of Sediment‐sensitive Invertebrates) which provides a proxy to describe the extent to which the surface of river beds are composed of, or covered by, fine sediments. Where suitable biomonitoring data exists, the index can be calculated retrospectively to track trends in fine sediment deposition, and its ecological impact, through time. Furthermore, the utilization of reference condition models such as RIVPACS (River InVertebrate Prediction And Classification System), allows site‐specific unimpacted conditions to be defined, opening‐up the possibility of standard classification and assessment systems being developed. In Europe, such systems are vital if the Water Framework Directive is to be implemented. Knowledge regarding spatial differences in sediment/flow interdependencies may provide valuable information on diffuse sources of fine sediment to rivers and we illustrate this with an example from the UK (Laceby Beck). Further UK case studies are presented to show a range of applications, including the demonstration of improvements in habitat heterogeneity following river restoration (rivers Chess and Rib) and the detection of fine sediment impacts downstream of an impoundment (Eye Brook). The PSI metric offers a readily deployable, cost‐effective and hydroecologically relevant methodology for the assessment of fine sediment impacts in rivers. The technique has potential for application outside of the UK and an adaptation of the methodology for use in the Simandou Mountains (Guinea) is used to illustrate this.

“…As with catchability and efficiency, few fisheries studies have estimated detectability, p. Detection probabilities vary among fish species and with habitat characteristics (Bayley and Peterson 2001;Burdick et al 2008;Hayer and Irwin 2008;Hewitt et al 2008). For example, seines are more efficient and, thus, have higher detection probabilities when used in unobstructed waters than when used in nearshore areas containing snags and other obstructions.…”

Detectability of Estuarine Fishes in a Beach Seine Survey of Tidal Tributaries of Lower Chesapeake Bay

Detectability, the probability of encountering a species at a sampling site, is often overlooked in fisheries research despite its potential to obscure inferences on habitat use and lead to biased estimates of abundance. We used occupancy models to explore factors affecting detectability and occupancy (Ψ), the probability that a species inhabits a site, for three fishes frequently captured in Chesapeake Bay seine surveys: young‐of‐the‐year (age‐0) striped bass Morone saxatilis, yearling Atlantic croaker Micropogonias undulatus, and spottail shiner Notropis hudsonius. Twelve repeat‐sampling events occurred during the summers of 2008 and 2009 at 20 sites in the Mattaponi and Pamunkey rivers, Virginia. Although the environmental factors that influenced detection probabilities varied with species, the detectability of all species was positively related to effective net length (i.e., the maximum distance from shore that the seine was deployed). The mean detectability of age‐0 striped bass, which occupied nearly every site (Ψ = 0.99, SE = 0.01), was 0.62 (SE = 0.06) and positively related to mean water temperature during sampling. The detectability of yearling Atlantic croakers was negatively related to water temperature at time of capture and was significantly greater in early summer than in late summer. In early summer, Atlantic croakers occupied all sampling sites; occupancy decreased in late summer (Ψ = 0.86, SE = 0.08) and was positively related to the mean salinity at the site. Unlike with Atlantic croakers, the mean detectability of spottail shiners was significantly greater in late summer than in early summer; detectability was positively related to turbidity at the time of sampling and reflected the increased availability of recently recruited individuals. Spottail shiners occupied fewer sites than did the two other species (Ψ = 0.59, SE = 0.21). Seasonal changes in detectability appeared to reflect changes in catchability associated with fish growth. Determining factors that influence detection probabilities is vital to improving our understanding of habitat use by fish and reducing the variation in fisheries sampling.

“…Patch occupancy modeling is a technique for estimating site occupancy that explicitly accounts for detection probability (MacKenzie et al 2002). Unfortunately, to our knowledge only two studies to date (Burdick et al 2008;Hayer and Irwin 2008) have been published in the fishery literature using this method.…”

Habitat selection by adult walleye during spawning season in irrigation reservoirs: a patch occupancy modeling approach

2011

Recruitment of walleye (Sander vitreusMitchill) is limited in irrigation reservoirs of the Republican River basin in southwestern Nebraska. The causal mechanism for this limited recruitment is unknown, but may be related to a lack of suitable spawning habitat. Patch occupancy models were developed to describe variation in detection probability and habitat selection during spawning season using shoreline electrofishing data. Detection of adult walleye was negatively affected by water temperature, silt substrate, and woody cover. Adult walleye selected sites with cooler water temperatures and greater fetch at Enders Reservoir, and large rock substrate and no cover at Hugh Butler Lake; these characteristics are limited to areas on or near the riprap dams in both reservoirs. Walleye eggs were also only found in these areas. We conclude that patch occupancy modeling provided valuable information when considering habitat improvement projects and propose a management approach for the addition of walleye spawning habitat in irrigation reservoirs.
