    ABSTRACT: The dynamics of stream and floodplain connectivity are a growing consideration for restoration projects. Restoration of a tributary stream to Utah Lake was undertaken in 2008 with the intent of increasing available spawning and nursery habitat for the endangered June Sucker Chasmistes liorus. Restoration efforts provided an opportunity to evaluate relationships between fish assemblages and variables related to the physiochemical environment, vegetation, and habitat connectivity at floodplain ponds. Fish were collected with beach seines and habitat variables were measured each month at 12 floodplain ponds during March 2010 to March 2011. Total catch was predominated by nonnative species: Green Sunfish Lepomis cyanellus, Western Mosquitofish Gambusia affinis, Black Bullhead Ameiurus melas, Fathead Minnow Pimephales promelas, and Bluegill Lepomis macrochirus. Both indirect and direct gradient analyses indicated a significant correlation between fish assemblages and site connectivity. The percentage and type of macrophyte cover (e.g., emergent, submergent) also played a significant role in structuring fish assemblages. Species richness was generally higher at sites with intermediate to high connectivity than at sites with lower connectivity. Sites with lower connectivity were predominated by Green Sunfish, Mosquitofish, and Fathead Minnow. June Suckers were collected from sites with intermediate values of connectivity and vegetation. Observed patterns suggested connectivity structured initial fish assemblages and macrophyte colonization dynamics; subsequent interactions between local habitat (i.e., percent vegetation) and biotic factors (e.g., competition, predation, etc.) provided site-specific interactions and structure. The results of this study indicate connectivity dynamics should be an important consideration in stream and floodplain restoration efforts.Received March 1, 2015; accepted September 30, 2015

    ABSTRACT: Bioenergetics modeling was used to determine individual and population consumption by Bloater Coregonus hoyi in Lake Michigan during three time periods with variable Bloater density: 1993–1996 (high), 1998–2002 (intermediate), and 2009–2011 (low). Despite declines in Bloater abundance between 1993 and 2011, our results did not show any density-dependent compensatory response in annual individual consumption, specific consumption, or proportion of maximum consumption consumed. Diporeia spp. accounted for a steadily decreasing fraction of annual consumption, and Bloater were apparently unable to eat enough Mysis diluviana or other prey to account for the loss of Diporeia in the environment. The fraction of production of both Diporeia and Mysis that was consumed by the Bloater population decreased over time so that the consumption-to-production ratio for Diporeia + Mysis was 0.74, 0.26, and 0.14 in 1993–1996, 1998–2002, and 2009–2011, respectively. Although high Bloater numbers in the 1980s to 1990s may have had an influence on populations of Diporeia, Bloater were not the main factor driving Diporeia to a nearly complete disappearance because Diporeia continued to decline when Bloater predation demands were lessening. Thus, there appears to be a decoupling in the inverse relationship between predator and prey abundance in Lake Michigan. Compared with Alewife Alosa pseudoharengus, the other dominant planktivore in the lake, Bloater have a lower specific consumption and higher gross conversion efficiency (GCE), indicating that the lake can support a higher biomass of Bloater than Alewife. However, declines in Bloater GCE since the 1970s and the absence of positive responses in consumption variables following declines in abundance suggest that productivity in Lake Michigan might not be able to support the same biomass of Bloater as in the past.Received May 11, 2015; accepted September 8, 2015

    ABSTRACT: We compared diet, stomach fullness, condition, and growth of Brown Trout Salmo trutta among streams with or without blooms of the benthic diatom Didymosphenia geminata in the Black Hills, South Dakota. In Rapid Creek, where D. geminata blooms covered ∼30% of the stream bottom, Brown Trout consumed fewer ephemeropterans (6–8% by weight) than individuals from two stream sections that have not had D. geminata blooms (Castle and Spearfish creeks; 13–39% by weight). In contrast, dipterans (primarily Chironomidae) represented a larger percentage of Brown Trout diets from Rapid Creek (D. geminata blooms present; 16–28% dry weight) compared with diets of trout from streams without D. geminata blooms (6–19% dry weight). Diets of small Brown Trout (100–199 mm TL) reflected the invertebrate species composition in benthic stream samples; in Rapid Creek, ephemeropterans were less abundant whereas dipterans were more abundant than in streams without D. geminata blooms. Stomach fullness and condition of Brown Trout from Rapid Creek were generally greater than those of Brown Trout from other populations. Linkages among invertebrate availability, diet composition, and condition of Brown Trout support the hypothesis that changes in invertebrate assemblages associated with D. geminata (i.e., more Chironomidae) could be contributing to high recruitment success for small Brown Trout in Rapid Creek.Received December 23, 2013; accepted October 13, 2015

    ABSTRACT: Coastal ecosystems along the northern Gulf of Mexico are highly productive and are affected by fishing and petroleum industries in different, sometimes contrasting, ways. As a result of the Deepwater Horizon (DWH) oil spill in April 2010, oil and oil dispersants were introduced into the northern Gulf of Mexico. At the same time, large portions of the Gulf of Mexico were closed to commercial and recreational fishing for most of the 2010 summer. This presented a unique opportunity to study the dynamics of a fish assemblage exposed to changes in two disparate types of anthropogenic disturbances. We compared assemblage data for near-coastal fish (456 samples representing over 45,000 individuals and 109 species) from pre-DWH (before 2010) and post-DWH (2011–2014) to assess potential changes in abundance, diversity (alpha, beta, and gamma), and assemblage structure. In contrast to predicted oil-induced mortality, post-DWH assemblages were characterized by high abundance in 2011 (CPUE across all species pooled was 2.5 times higher than in any other year). This high abundance was most pronounced in medium-sized fish species that are direct targets of commercial fishing or likely bycatch. Abundances returned to levels similar to pre-DWH in 2012, 2013, and 2014. There were no differences in pre- and post-DWH levels of diversity, and shifts in assemblage structure may be consistent with increases driven by reduced fishing pressure. While other assemblages and ecosystems may respond differently, our data for the near-coastal fish assemblage indicated the effects of the DWH were minimal. Rigorous empirical data from other systems are required to assess potential DWH impacts across the range of ecosystems potentially affected.Received March 6, 2015; accepted October 9, 2015

    ABSTRACT: To restore habitat for wild trout, Kleinschmidt Creek, a low-gradient, groundwater-dominated stream in the Blackfoot Basin, Montana, was reconstructed using natural channel design principles. Reconstruction increased stream sinuosity from a ratio of 1.1 to 1.6, decreased mean channel width from 14.5 to 2.8 m, and increased sediment transport capacity to reduce accumulations of fine instream sediment. To further improve trout habitat, coarse woody debris (CWD) was variably placed within the new channel and livestock were excluded to promote the vegetative recovery of the riparian area. To evaluate the response of wild trout (92% Brown Trout Salmo trutta) to channel restoration, the abundance (number of trout per linear meter) and biomass (g/linear m) of age 1+ trout were monitored for 15 years (1998–2012) in a reach with low density CWD (1.3 stems/100 m) and compared with regional (reference) trends. Posttreatment (2002–2012) trout numbers in the low-density CWD reach were also compared with those in a reach with high-density CWD (18.2 stems/100 m). Long-term trends for the reference reaches showed a significant negative trend in trout abundance and no significant trend for biomass. Long-term trends for the low-density CWD reach showed a significant positive trend in abundance, as well as a significant trend in biomass. Trout abundance and biomass increased over the posttreatment period in the low-density CWD reach. However, in the high density CWD reach, while posttreatment abundance increased significantly, there was no significant trend in biomass. These results demonstrated that channel restoration increased wild trout populations in a deep, narrow, vegetated stream and that instream wood provided primarily short-term benefits during the early phase of habitat recovery.Received November 26, 2013; accepted October 18, 2014

    ABSTRACT: Adult anadromous lampreys attack several species targeted by large-scale commercial fisheries in the North Pacific Ocean, and the potential negative impact to these host fishes is not well understood. The Arctic Lamprey Lethenteron camtschaticum and Pacific Lamprey Entosphenus tridentatus are anadromous species that feed in the eastern Bering Sea, and lamprey parasitism is evident on Pacific Cod Gadus macrocephalus near the Bering Slope. To examine this parasitic interaction, we first built models using morphological measurements from lamprey oral discs to predict which lamprey species caused the observed wounds on Pacific Cod. We then examined lamprey wounding rates and explored healing patterns related to the severity and location of lamprey wounds. We scanned 8,746 Pacific Cod for lamprey wounds and found that 4.9% of the cod had at least one wound. Lamprey wound morphology was better predicted by an oral disk model built for Pacific Lamprey than by a similar model built for Arctic Lamprey. The occurrence of lamprey wounds that had penetrated muscle tissue but had not completely healed was more prevalent as Pacific Cod length increased. Generalized additive model results indicated that latitude and mean Pacific Cod length were important in predicting lamprey wounding rates at a sampling station. Recently inflicted lamprey wounds that penetrated Pacific Cod muscle tissue were observed four times as often as superficial wounds that did not penetrate muscle tissue, but superficial wounds were twice as likely to reach a completely healed state. No difference was detected in the likelihood of a lamprey wound to reach a completely healed state among different host body regions. While there is a potential for lamprey attacks to negatively affect individual host fish, we emphasize the importance of understanding population dynamics between native lampreys and their hosts, as this could aid in explaining variations in the natural mortality of commercially important fish species in the eastern Bering Sea.Received March 9, 2015; accepted June 22, 2015

    ABSTRACT: We address the question of spatial extent: how model results depend on the amount and type of space represented. For models of how stream habitat affects fish populations, how do the amount and characteristics of habitat represented in the model affect its results and how well do those results represent the whole stream? Our analysis used inSalmo, an individual-based model of anadromous salmonid spawning, incubation, and juvenile rearing. The model was applied to 12 sites, totaling 4.0 km in length, on Clear Creek, California, treating the simulated 4.0 km as a synthetic whole stream. Simulation experiments examined responses of anadromous salmonid spawning and rearing success to habitat variables, such as flow and temperature, when the model included each individual site, all sites, and random combinations of two to nine sites. Some responses, such as temperature effects on egg incubation, were insensitive to spatial extent. Other responses, including the effects of flow on the production of large juveniles, varied sharply among sites and varied with spatial extent. Most small sites had little effect on overall results, but one small site provided exceptionally good juvenile rearing habitat and strongly affected the responses of the entire stream. Larger sites (length > 15 channel widths) in distinct habitat types (e.g., highly disturbed and recently restored) also had strong effects. Including more or longer sites generally increased model representativeness but not consistently. Results highly representative of the entire stream could also be obtained by combining large sites in typical habitat with “hot spots” of especially productive habitat. Finally, sites lower in the watershed appear to be more important to model results and anadromous salmonid spawning success because more juveniles migrate through them.Received February 4, 2015; accepted July 25, 2015
