“…The effect of turbidity is logical: clearer water allows visual predators to see and catch prey more easily. The effects of turbidity on predation in aquatic environments have been well documented in laboratory experiments (Abrahams and Kattenfeld 1997;Carter et al 2010), including evidence that turbidity negatively affects the foraging success of piscivorous fish to a significantly greater extent than planktivorous fish (De Robertis et al 2003). Data from the wild are lacking; higher turbidity has been correlated with increased recruitment in some freshwater ecosystems (Reichert et al 2010), but the mechanism for this effect is not clear.…”

We examined predation by nonnative Mississippi Silversides Menidia audens, other small fishes, and invertebrates on the early life stages of the endangered Delta Smelt Hypomesus transpacificus, which is endemic to the Sacramento–San Joaquin Delta in California. Mississippi Silversides and other putative predators were collected primarily via boat electrofishing in the northern reaches of the upper San Francisco Estuary, an area targeted for substantial tidal wetland restoration to enhance habitat for Delta Smelt and other endangered fishes. Predators’ digestive tracts were removed and analyzed for the presence of Delta Smelt DNA by using quantitative PCR TaqMan assays. Across all sites, 69 of 550 Mississippi Silversides tested positive for Delta Smelt DNA. The number of sampled Mississippi Silversides that were positive for Delta Smelt DNA was significantly greater in offshore habitats than in nearshore habitats. Delta Smelt DNA detection data indicated that a wide variety of other species were also predators of Delta Smelt. Additionally, we used generalized linear modeling to analyze the relationship between Delta Smelt predation detections in Mississippi Silversides and concurrently collected habitat parameters. Turbidity was identified as a significant predictor of predation, as Delta Smelt DNA was detected more often in Mississippi Silverside samples from clearer water. These results suggest that restoration efforts designed to increase turbidity in the estuary may be beneficial in reducing Mississippi Silversides’ predatory impacts on Delta Smelt.Received August 24, 2015; accepted February 3, 2016 Published online June 15, 2016

“…Additional factors that may also influence prey selection include prey body size, mobility, density, distribution, and quality (i.e., energy content) (Gray 2005;Zhao et al 2006). However, when estuarine fishes have turbiditycaused visual impairment may reduce the influence of these factors may influence prey selectivity less (Koski et al 2003;Carter et al 2010).…”

Tidal marsh wetlands provide important foraging habitat for a variety of estuarine fishes. Prey organisms include benthic/epibenthic macroinvertebrates, neustonic arthropods, and zooplankton. Little is known about the abundance and distribution of interior marsh macroinvertebrate communities in the San Francisco Estuary (estuary). We describe seasonal, regional, and site variation in the composition and abundance of neuston and benthic/epibenthic macroinvertebrates that inhabit tidal marsh channels, and relate these patterns to environmental conditions. We also describe spatial and temporal variation in diets of marsh-associated inland silverside, yellowfin goby, and western mosquitofish. Fish and invertebrates were sampled quarterly from October 2003 to June 2005 at six marsh sites located in three river systems of the northern estuary: Petaluma River, Napa River, and the west Delta. Benthic/epibenthic macroinvertebrates and neuston responded to environmental variables related to seasonal changes (i.e., temperature, salinity), as well as those related to marsh structure (i.e., vegetation, channel edge). The greatest variation in abundance occurred seasonally for neuston and spatially for benthic/epibenthic organisms, suggesting that each community responds to different environmental drivers. Benthic/epibenthic invertebrate abundance and diversity was lowest in the west Delta, and increased with increasing salinity. Insect abundance increased during the spring and summer, while Collembolan (springtail) abundance increased during the winter. Benthic/epibenthic macroinvertebrates dominated fish diets, supplemented by insects, with zooplankton playing a minor role. Diet compositions of the three fish species overlapped considerably, with strong selection indicated for epibenthic crustaceans-a surprising result given the typical classification of Menidia beryllina as a planktivore, Acanthogobius flavimanus as a benthic predator, and Gambusia affinis as a larvivorous surface-feeder. Fish diets were influenced by position along the estuarine gradient and season. Overall, our data show that local-scale site effects and marsh position within the estuary influence invertebrate community composition and abundance. Additionally, we show that restoring marsh ecosystems can subsidize fishes similarly to reference marshes. We thus recommend that managers focus on the ability of restoring marshes to produce food subsidies for target species when planning and designing tidal marsh restoration projects, especially those targeted for food web support.

“…Foraging success of adult rainbow trout Oncorhynchus mykiss on salmon fry Oncorhynchus nerka was affected by turbidity (Ginetz and Larkin 1976), but no effect was found when adult cutthroat trout was the predator (Gregory and Levings 1996). Predation rates by smallmouth bass Micropterus dolomieu decreased with increasing turbidity, and smallmouth bass consumed more golden shiners Nitemigonus crysoleucas (a pelagic fish) but fewer round goby Neogobius melanostomus (a benthic fish) with increasing turbidity (Carter et al 2010). In addition, some other factors such as experimental period and the size of the experimental containers should be taken into account.…”

“…Increased turbidity can have negative effects on the foraging success of fish (Gregory 1993;Miner and Stein 1993;Gregory and Levings 1998;Radke and Gaupisch 2005;Pekcan-Hekim and Lappalainen 2006;Carter et al 2010), but does not affect the foraging success of some species (Bergman 1988;Vandenbyllaardt et al 1991;Reid et al 1999;Granqvist and Mattila 2004), and can even enhance foraging efficiency (Gregory and Northcote 1993). Little is known on the combined effects of turbidity and light on predation of juvenile piscivorous fish, and no information is available on juvenile mandarin fish.…”

This study aimed to evaluate the effects of turbidity and light intensity on foraging success of juvenile mandarin fish Siniperca chuatsi. Predation on crucian carp Carassius auratus by juvenile mandarin fish was tested at five levels of turbidity combined with two light intensities, imitating daylight and night in two turbidity types. Foraging success was significantly lower in clay-induced turbidity than in algalinduced turbidity. In clay-induced turbidity trials, there was a slight but insignificant increase in foraging success of mandarin fish with increasing turbidity under lighted conditions. In algal-induced turbidity trials, there were no significant differences in foraging success of mandarin fish among turbidity levels at both light and dark levels, but at 80 NTU turbidity level, foraging success was lower than in all the other turbidity levels. There was no significant difference in foraging success at different turbidities under darkness. These results suggest that piscivory of mandarin fish is influenced by different turbidity types but is not significantly influenced by increased turbidity combined with decreased light intensity.
