This book was released on 2013 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural streams provide infrastructure for flood control and are periodically straightened and dredged to maintain their efficiency to drain farm land. These streams also serve as headwaters and may provide important spawning and refuge habitat for native fish. Twenty study sites were selected in Sandusky, Crawford and Seneca counties (Ohio) and sampled for habitat and fish community variables in June and September during each of four years (2008-2011). Sites had to (1) be surrounded by agricultural land, (2) likely hold water in the summer, (3) lack canopy cover, (4) represent varying times since last dip-out, and (5) have landowner permission for access. I included streams from both lake plain and morainal regions. Measures of stream morphology, time-since-last-dredging and selected habitat variables were correlated with fish community metrics such as abundance, richness, Simpson's Index, Shannon Diversity, and Index of Biotic Integrity. Fish communities were assessed using block seines in 50 m stream segments. Captured fish were identified to species, counted, assigned to an age class, inspected for gravidity and DELT, and released outside of the sampling segment downstream to prevent recapture. A total of 38,074 individual fish were sampled belonging to 35 species. Fathead minnow (10,068), creek chub (5,252), bluntnose minnow (4,737), central stoneroller (4,185), blacknose dace (3,942), blackstripe topminnow (3,803) and Johnny darter (1474) were most common and comprised 88% of the total fish catch. Non-native fish (wild goldfish, common carp, and mosquitofish) comprised only 0.1% of the total abundance. Adult fish data were combined into a June and September dataset to produce a more robust dataset and minimize pseudo replication. Channel morphology, expressed per site as the coefficient of variation of 11 wetted-stream width measurements (CoV-H) correlated weakly with year-since-last-dip-out (r=0.35, p=0.11) with a non-linear regression predicting only 14% of the variation. The coefficient of variation of 11 maximum water depth measurements (CoV-V) did not correlate with year-since-last-dip-out. Only IBI was significantly linked with CoV-V for the combined June and the combined September data (r=53, p=0.02; r=0.60, p=0.01, respectively). Using a non-parametric approach (Mann-Whitney), sites in morainal regions displayed a significantly higher CoV-V (z=3.08; p=0.002), whereas the difference in CoV-H approached significance (z=1.79; p=0.074). Lake plain and morainal sample sites did not differ in their year-since-last-dip-out (z=0.80; p=0.424) and IBI was the only fish community variable that was significantly higher in morainal streams than in lake plain sites for June and September (z=2.43; p=0.015 and z=2.28; 0.023, respectively). Cluster analysis did not produce obvious groupings based on physiography, location in the watershed or season of sampling. The fish community composition in each stream, however, is impacted by a multitude of biotic and abiotic factors that are difficult to separate. Agricultural streams provide habitat to a great number of fish and a substantial number of native species. Such environmental considerations should be considered in the management of these man-made streams.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2018, the Ballville Dam was removed from the Sandusky River, Ohio. The removal of the dam was expected to reconnect areas of upstream habitat, restore fish passage, and improve the fish community. To assess the quantity and quality of available walleye spawning habitat post-dam removal, a habitat suitability index (HSI) model was developed. Model results indicated that there is more walleye spawning habitat upstream of the former dam. Electrofishing surveys were conducted during the spring of 2020 and 2021 (to assess migratory fish passage above the dam) and during summer 2020 (to assess the resident fish community). Walleye were captured upstream of the dam during the 2021 spawning run. Overall, walleye and white bass catch rates and spawn run strengths were lower in post-assessments compared to values seen pre-dam removal. The results of the 2020 post-assessment suggest that the quality of the resident fish community has declined across the study area since the 2009 pre-assessment. However, changes in habitat quality between assessments were less apparent. This study documents the short-term effects of dam removal on river conditions and the fish community post-dam removal.
