Habitat Partitioning And Associated Morphological Differences Among Three Species Of Catostomidae (Teleostei: Actinopterygii) In The South Fork Roanoke River, Virginia, Steven L. Powers, Dakota R. Spruill

Virginia Journal of Science

The upper Roanoke River has 11 species of Catostomidae including Thoburnia rhothoeca, Torrent Sucker; Moxostoma cervinum, Blacktip Jumprock; and Moxostoma ariommum, Bigeye Jumprock. Resource partitioning appears to be a key component of maintaining diverse fish assemblages with habitat and food partitioning cited as especially important in communities containing members of the same family. The diets of these species have been documented in previous work revealing only modest differences among them. Snorkeling observations and subsequent quantification of microhabitat were conducted to illuminate habitat partitioning among these morphologically and ecologically similar species. Thoburnia rhothoeca inhabited the shallowest, fastest water, over the …

Shark Diversity And Relative Abundance At Myrtle Beach, Sc Fishing Piers, Lynsey E. Isner

Honors Theses

Sharks are frequently observed at fishing piers (Barwick et al. 2004; Martin et al. 2019). These piers offer structural habitats for shark prey items, such as smaller fish and invertebrates, which can attract sharks to piers (Barwick et al. 2004; Heupel 2005). Additionally, fishers often clean their catch and discard entrails at the pier, which also may attract sharks (Martin et al. 2019). Moreover, other factors could play a role in attracting sharks to piers. These include water quality parameters, like salinity and temperature, and the physical characteristics of the pier (Ulrich et al. 2007; Castro 1996; Heupel 2005).

Evaluation Of Lake Sturgeon (Acipenser Fulvescens) Spawning Success On An Artificial Reef Constructed In The Kalamazoo River, Michigan, Jason P. Lorenz

Masters Theses

Since lake sturgeon Acipenser fulvescens monitoring began on the Kalamazoo River in 2009, there has been no documentation of survival past the egg stage. Spawning has occurred directly below Calkins Dam and, in 2016, an artificial spawning reef was constructed 275-m downstream to improve habitat and increase survival to the larval stage. The site was monitored with egg mats and larval drift nets to document evidence of successful natural reproduction of lake sturgeon one year prior to construction (2016) and three years post-construction of the artificial reef (2017-2019). Fertilized lake sturgeon eggs were captured all four years of the study …

Fishing For Food: Values And Benefits Associated With Coastal Infrastructure, Cassandra M. Nieman, Alexie N. Rudman, Margaret L. Chory, Grant D. Murray, Luke Fairbanks, Lisa M. Campbell

Faculty Publications

While there is substantial literature about the socio-cultural characteristics and values associated with recreational and commercial fisheries in the U.S., studies directed at those who ‘fish for food’—those who depend on consuming their catch to various degrees—are relatively sparse. Using qualitative data collected through 80 semi-structured interviews with fishers in the summer and fall of 2018 in Carteret County, North Carolina, this study aims to better understand the group of recreational fishers who consume their catch by describing social and cultural dimensions and values associated with fishing for food, examining the role of infrastructure in facilitating access to benefits associated …

Checklist Of The Inland Fishes Of Louisiana, Michael H. Doosey, Henry L. Bart Jr., Kyle R. Piller

Southeastern Fishes Council Proceedings

Since the publication of Freshwater Fishes of Louisiana (Douglas, 1974) and a revised checklist (Douglas and Jordan, 2002), much has changed regarding knowledge of inland fishes in the state. An updated reference on Louisiana’s inland and coastal fishes is long overdue. Inland waters of Louisiana are home to at least 224 species (165 primarily freshwater, 28 primarily marine, and 31 euryhaline or diadromous) in 45 families. This checklist is based on a compilation of fish collections records in Louisiana from 19 data providers in the Fishnet2 network (www.fishnet2.net). The checklist has grown because of descriptions of three new species, new …

Fish Associations With Shallow Water Subsea Pipelines Compared To Surrounding Reef And Soft Sediment Habitats, Karl D. Schramm, Michael J. Marnane, Travis S. Elsdon, Christopher M. Jones, Benjamin J. Saunders, Stephen J. Newman, Euan S. Harvey

Fisheries Research Articles

Offshore decommissioning activities are expected to increase as oil and gas subsea infrastructure becomes obsolete. Decisions on decommissioning alternatives will benefit from quantifying and understanding the marine communities associated with these structures. As a case study, fish assemblages associated with an inshore network of subsea pipelines located on the North West shelf of Western Australia were compared to those in surrounding natural reef and soft sediment habitats using remotely operated vehicles fitted with a stereo-video system (stereo-ROVs). The number of species, the abundance, biomass, feeding guild composition and the economic value of fishes were compared among habitats. The community composition …

Isolated Reefs Support Stable Fish Communities With High Abundances Of Regionally Fished Species, Matthew J. Birt, Katherine Cure, Shaun Wilson, Stephen J. Newman, Euan S. Harvey, Mark G. Meekan, Conrad W. Speed, Andrew Heyward, Jordan Goetze, James Gilmour

Fisheries Research Articles

Anthropogenic impacts at isolated and inaccessible reefs are often minimal, offering rare opportunities to observe fish assemblages in a relatively undisturbed state. The remote Rowley Shoals are regarded as one of the healthiest reef systems in the Indian Ocean with demonstrated resilience to natural disturbance, no permanent human population nearby, low visitation rates, and large protected areas where fishing prohibitions are enforced. We used baited remote underwater video systems (BRUVS) to quantify fish assemblages and the relative abundance of regionally fished species within the lagoon, on the slope and in the mesophotic habitat at the Rowley Shoals at three times …

Using Acoustic Telemetry To Analyze The Impacts Of Common Carp On Wild Rice Restoration, Franklin Zomer

All NMU Master's Theses

Wild rice (Zizania palustris) is an important cultural, spiritual, and dietary resource to Lake Superior Ojibwe. Common Carp (Cyprinus carpio) are an introduced species that negatively impact aquatic vegetation through changes in water quality, uprooting of plants, and consumption of seed. Acoustic telemetry was used to document Common Carp movements in Waishkey Bay in the upper St. Marys River, MI where wild rice habitat is present. Exclosures were established to measure the influence of carp presence on wild rice seeding success. Common Carp were observed to spend much of their time in Waishkey Bay but also …

Executive Summary

The Heartland Inventory and Monitoring Network (HTLN) is a component of the National Park Service’s (NPS) strategy to improve park management through greater reliance on scientific information. The purposes of this program are to design and implement long-term ecological monitoring and provide information for park managers to evaluate the integrity of park ecosystems and better understand ecosystem processes. Concerns over declining surface water quality have led to the development of various monitoring approaches to assess stream water quality. Freshwater streams in network parks are threatened by numerous stressors, most of which originate outside park boundaries. Stream condition and …

The Effects Of Temperature And Body Size On The Metabolism And Hypoxia Tolerance Of White Abalone (Haliotis Sorenseni) And Red Abalone (H. Rufescens), Stephanie Fan

Theses

In 2001, white abalone, Haliotis sorenseni, became the first marine invertebrate to be listed under the U.S. Endangered Species Act. Allee effects due primarily to overharvesting and disease resulted in individuals being too far apart for successful fertilization. Despite the fishery closure in 1996, H. sorenseni still shows no signs of recovery. Today, the White Abalone Recovery Consortium (WARC), a group that includes federal and state agencies, aquaculture organizations, academic institutions, and public aquaria, is working to recover this endangered species back from the brink of extinction.

In order to better understand the metabolic demands and hypoxia tolerance of the …

Atlantic Sailfish (Istiophorus Albicans) Distribution Off The East Coast Of Florida From 2003 To 2018 In Response To Sea Surface Temperature, Meredith M. Pratt

Mako: NSU Undergraduate Student Journal

The Atlantic sailfish (Istiophorus albicans) ranges from 40°N to 40°S in the Western Atlantic Ocean and has great economic and recreational value for sport fishers. Off the east coast of Florida, recreational fishing boats often target this species due to its size, speed and strength. This project aimed to determine the relationship between sea surface temperature (SST) and the distribution of Atlantic sailfish caught and released over a fifteen-year period (2003 to 2018). Tagging information was collected from The Billfish Foundation and NOAA who have the most extensive programs for billfish. Using the time and location of each …

Economics Department Faculty Publications

The Municipality of Lake Sebu in Mindanao; Philippines offers various opportunities for income-generating fishing activities with its abundant surface water bodies. Lake Sebu is particularly known for good quality tilapia; farmed in fish cages. This study employed primary data collection methods; namely key informant interview; focus group discussion and a comprehensive livelihood household survey to assess the conditions and problems constraining fishing households in Lake Sebu. The study found that fishing-related benefits were mainly derived from aquaculture. Capture fisheries are essentially very small-scale; low gear open fishing done by local fisher folk that generates only subsistence income. Local residents are …

Large-Scale Edna Metabarcoding Survey Reveals Marine Biogeographic Break And Transitions Over Tropical North-Western Australia, Katrina M. West, Michael J. Travers, Michael Stat, Euan S. Harvey, Zoe T. Richards, Joseph D. Dibattista, Stephen J. Newman, Alastair V. Harry, Craig L. Skepper, Matthew Heydenrych, Michael Bunce

Fisheries Research Articles

Environmental DNA (eDNA) metabarcoding has demonstrated its applicability as a highly sensitive biomonitoring tool across small spatial and temporal scales in marine ecosystems. However, it has rarely been tested across large spatial scales or biogeographical barriers. Here, we scale up marine eDNA metabarcoding, test its ability to detect a major marine biogeographic break and evaluate its use as a regional biomonitoring tool in Australia.

Monochloramine ( is a secondary disinfectant used by water treatment facilities to eliminate lingering bacteria in basins, filters, and pipelines. While an effective disinfectant, monochloramine can have negative effects on aquatic organisms. Organis ms affected by the chemical can include species whose environment is near to effluent sites and aquaculture facilities that use tap water lines or has water intake pipes near to effluent sites. Three species commonly found in south Florida that are lik ely exposed to MCA by effluent sites or aquaculture facilities are mosquitofish Gambusia affinis pink shrimp Farfantepenaeus duorarum and the hard clam Mercenaria mercenaria These …

Ontogenetic Variation In Sciaenid Otolith Morphometry With Fish Size From The Northern Gulf Of Mexico, Thomas C. Ingalls

All HCAS Student Capstones, Theses, and Dissertations

Sciaenids are a diverse family of coastal fishes and their fisheries are an important industry in the United States. In the northern Gulf of Mexico this industry is dominated by six species, specifically, red drum (Sciaenops ocellatus), black drum (Pogonias cromis), spotted seatrout (Cynoscion nebulosus), sand seatrout (C. arenarius), Atlantic croaker (Micropogonias undulatus), and spot (Leiostomus xathurus). Sagittal otoliths of all species were evaluated for changes in size and shape in relation to changes in fish total length and age across a variety of seasons and habitats. Evaluation …

Assessing The Toxicity Of A Reconstituted Water Simulating Streams Influenced By Mountaintop Mining In Central Appalachia, Benjamin David Browning

Theses, Dissertations and Capstones

Freshwater ecosystems in Central Appalachia experience increased concentrations of manganese (Mn) and total dissolved solids from the runoff of surface mines and valley fills. Biological communities have been impacted by these surface mining operations and it has been suggested that the increase in total dissolved solids may contribute to these negative effects, but standard laboratory toxicity tests have not found increased concentrations of total dissolved solids to have such negative effects as seen in the field. The elevated total dissolved solids in mining influenced streams may only be toxic in conjunction with another toxicant that is presence in these systems …

Red Drum And Spotted Seatrout Live-Release Tournament Mortality And Dispersal, T. Reid Nelson, Crystal Hightower, Sean P. Powers

University Faculty and Staff Publications

Although catch-and-release fishing tournaments undoubtedly reduce mortality of target species, postrelease mortality and fish stockpiling at release sites remain common concerns related to these tournaments. The impacts of liverelease tournaments on freshwater species have been widely studied. However, research on estuarine sport fishes is lacking even though catch-and-release tournaments targeting these species are prevalent and popular recreational fisheries exist. Therefore, we estimated the post-weigh-in mortality and dispersal of Red Drum Sciaenops ocellatus and Spotted Seatrout Cynoscion nebulosus released from the 2016–2018 Alabama Deep Sea Fishing Rodeo live-weigh-in categories using acoustic telemetry. To concurrently estimate overall post-weigh-in mortality and dispersal, we …

An Exceptionally Small New Polycotylid Plesiosaur (Reptilia: Sauropterygia) With Raptorial Eyes From The Western Interior Seaway Of North America, Robert O’Brien Clark

Theses, Dissertations and Capstones

Polycotylidae is a family of plesiosaurian marine reptiles that evolved during the Early Cretaceous and radiated into multiple genera during the Late Cretaceous, achieving a worldwide distribution. Derived polycotylids of the subclade Polycotylinae have a gracile and elongated rostrum, homodont dentition, an extended mandibular symphysis, and foreshortened temporal fenestrae. In this thesis, I describe a small and highly derived new polycotylid taxon based on three specimens from the Campanian of the Western Interior Seaway in North America. A high number of maxillary teeth, fused neural arches, propodials with well-defined facets, and heavily remodeled cortical bone indicate the specimens are adults, …
