Population Demography, Occupancy, And Connectivity Of Invasive Bigheaded Carp In The Platte River, Nebraska And Its Tributaries, Blake W. Logan
School of Natural Resources: Dissertations, Theses, and Student Research
Silver Carp Hypophthalmichthys molitrix and Bighead Carp H. nobilis, collectively referred to as bigheaded carp, are invasive species in the United States of America that have expanded their range throughout the Missouri River basin in the last three decades. It may be desirable to develop management plans directed at the monitoring, control, or removal of bigheaded carp within the Missouri River basin. However, a knowledge gap exists regarding bigheaded carp ecology in Missouri River tributaries, which may be important for the development of management plans. As such, this study characterized bigheaded carp population demographics, occupancy, and connectivity in …

An Exploration Of Palauan Fishing Methods And Fisheries: A Study For The Conservation Of Dugongs, Mia Glover
An Exploration Of Palauan Fishing Methods And Fisheries: A Study For The Conservation Of Dugongs, Mia Glover
Electronic Theses and Dissertations
The dugong (Dugong dugon) is an important marine mammal in Palau. However, current population dynamics are not well understood. This study aimed to connect scientific data with local knowledge by examining the social implications of changing fishing methods and their impact on dugong population dynamics in the face of climate change and fisheries commercialization. Through interviews with local fishers, it was found that destructive fishing methods like trawling and long lining have led to habitat loss and degradation for dugongs. These tactics, driven by economic factors, have disrupted the delicate balance between human activities and the preservation of dugong habitats, …
American Eel (Anguilla Rostrata) And Other Fishes As Surveyed By Environmental Dna In The Bronx River And Hudson River Watershed, Sam C. Chin
Dissertations, Theses, and Capstone Projects
Mounting an effective response to the threats faced by freshwater fish may require expansions to aquatic biomonitoring in excess of what is feasible using the capture-based survey techniques currently relied upon by natural resource managers. Methods for analyzing environmental DNA (eDNA) are emerging as a minimally invasive and cost-effective approach for surveying fish and other organisms. By detecting taxon-specific DNA sequences recovered from environmental samples (e.g. water, sediment), eDNA methods are able to infer species presence from samples that can be collected rapidly with simple equipment. In many cases, eDNA detection rates of fish species have been shown to meet …

Abundance Of Shell-Boring Polychaete Worms And Other Fouling Organisms In Aquacultured Oysters From Maine Used For Reef Restoration In Great Bay, Nh, Haleigh Wright
Honors College
Restoration projects on the oyster reefs in Great Bay, NH have been active since 2009 with the most recent involving the transfer of oysters from Maine oyster farms into the Bay. In an attempt to prevent the transfer of non-native species from oyster farms to the reefs, samples of oysters from each farm were inspected for shell-boring polychaete infestations. Polydora websteri, a common shell-boring species worldwide, was in high abundance in reference samples from oyster farms in Great Bay and in samples from the restoration grounds, themselves. A second shell-boring species, provisionally identified as P. onagawaensis, is present on oyster …

The scale and drivers of marine biodiversity loss are being revealed by the International Union for Conservation of Nature (IUCN) Red List assessment process. We present the first global reassessment of 1,199 species in Class Chondrichthyes-sharks, rays, and chimeras. The first global assessment (in 2014) concluded that one-quarter (24%) of species were threatened. Now, 391 (32.6%) species are threatened with extinction. When this percentage of threat is applied to Data Deficient species, more than one-third (37.5%) of chondrichthyans are estimated to be threatened, with much of this change resulting from new information. Three species are Critically Endangered (Possibly Extinct), representing …
Assessing The Short-Term Effects Of Translocation On Freshwater Mussels: Is Habitat Or Water Quality More Important?, Joshua D. Arnold
Assessing The Short-Term Effects Of Translocation On Freshwater Mussels: Is Habitat Or Water Quality More Important?, Joshua D. Arnold
Masters Theses
Freshwater mussels (Order: Unionida) are very important to the function of aquatic ecosystems and are typically indicators of good water quality. They provide a valuable link between the water column and the benthic substrate in which they live and are a valuable food resource for many species of animals. However, most species native to North America are currently threatened with extinction, to the point that more than 70% of native freshwater mussels are listed as either threatened or endangered at the state or federal level. The cause of this decline can be attributed to historical over exploitation, habitat alteration, and …
Vignette 04: Olympia Oysters, Jodie Toft, Betsy Peabody
Vignette 04: Olympia Oysters, Jodie Toft, Betsy Peabody
Institute Publications
Olympia oysters (Ostrea lurida) are our only native oyster species here in the Salish Sea. Olympia oysters once covered an estimated 13-26% of the intertidal area in Puget Sound, mostly near the heads of inlets. A combination of overharvest, pollution, and habitat loss reduced the current population to less than 4% of historic numbers, though sparse numbers of Olympia oysters can still be found throughout most of their historic distribution. Looking to the future, as our region’s marine waters experience effects of climate change and ocean acidification (OA), native species such as the Olympia oyster may prove to …
An Ecosystem Is Not A Monument, And Other Challenges To Fishing In The 21st Century, Roger Mann
An Ecosystem Is Not A Monument, And Other Challenges To Fishing In The 21st Century, Roger Mann
VIMS Articles
The continental shelf of the United States was once the preserve of commercial fishermen. This is no longer the case. The exclusive economic zone is increasingly becoming the focus of other economically powerful, sometimes incompatible uses, including green energy, shipping, communications, mining, military exclusion zones, and conservation regions. These other uses generally have fixed boundaries. The distribution of fished species moves in relation to warming of shelf waters, presenting challenges to both federal regional fishery management councils and industry alike. There is need for continued engagement between user groups with respectful use of guiding science and legal structure to ensure …
Potential Solar Replacement Of Hydroelectricity To Reopen Rivers: Maine As A Case Example, Shailesh Sharma, John Waldman
Potential Solar Replacement Of Hydroelectricity To Reopen Rivers: Maine As A Case Example, Shailesh Sharma, John Waldman
Publications and Research
Hydroelectricity provides 6% of U.S. electrical power needs, but hydro-dams also cause environmental harm, including the retardation or complete blockage of spawning runs of anadromous fishes. To facilitate fish movements, engineered-fishways have long been used but many have performed poorly. Dam-removal is the most effective way of restoring dwindling migratory fish populations by allowing unrestricted pathways to their spawning areas and for the downstream migrations of post-spawning adults and juveniles. However, removals of hydro-dams result in a loss of electricity production. For the replacement of energy foregone from hydro-dam removals, various alternative energy installations are now feasible. We present one-to-one …

Limitations On Inferring Shark Vulnerability From Spatial Habitat Protection. Response To Shark Conservation Hindered By Lack Of Habitat Protection, Matias Braccini, Stephen J. Newman
Limitations On Inferring Shark Vulnerability From Spatial Habitat Protection. Response To Shark Conservation Hindered By Lack Of Habitat Protection, Matias Braccini, Stephen J. Newman
Fisheries Research Articles
Birkmanis et al. (2020a) used occurrence data obtained from commercial fisheries to infer the suitable habitat for eight shark species within the Exclusive Economic Zone (EEZ) of Australia, and quantify the amount of suitable habitat contained within existing no-fishing Marine Protected Areas (MPAs). The authors state that shark conservation is hindered because suitable habitat is mostly unprotected from commercial fishing, therefore increasing the vulnerability of the assessed species. In doing so, the authors imply that shark conservation depends predominantly on establishing MPAs in highly suitable habitats; this, unfortunately, would disregard the broad range of other measures available in the fisheries …
Distribution, Density, Movement, And Support For Management Of Mountain Sucker, Pantosteus Jordani, In The Black Hills Of South Dakota, Seth J. Fopma
Distribution, Density, Movement, And Support For Management Of Mountain Sucker, Pantosteus Jordani, In The Black Hills Of South Dakota, Seth J. Fopma
Electronic Theses and Dissertations
Mountain Sucker, Pantosteus jordani, is a cold-water species native to the Intermountain West. Fringe populations of Mountain Sucker have experienced declines in recent decades. The population of Mountain Sucker found in the Black Hills of South Dakota represents the eastern fringe of the species’ native range. Recognized as both an indicator of biologic health and as a species of greatest conservation need in South Dakota, recent studies have suggested significant declines in both distribution and abundance. Despite the recent study of Mountain Sucker in the region, increased understanding of Mountain Sucker ecology is needed to effectively manage for the conservation …

Operationalizing Ecological Resilience Concepts For Managing Species And Ecosystems At Risk, Jeanne C. Chambers, Craig R. Allen, Samuel A. Cushman
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
This review provides an overview and integration of the use of resilience concepts to guide natural resources management actions. We emphasize ecosystems and landscapes and provide examples of the use of these concepts from empirical research in applied ecology. We begin with a discussion of definitions and concepts of ecological resilience and related terms that are applicable to management. We suggest that a resilience-based framework for management facilitates regional planning by providing the ability to locate management actions where they will have the greatest benefits and determine effective management strategies. We review the six key components of a resilience-based framework, …
Assessing Populations Of Eastern Brook Trout (Salvelinus Fontinalis) Above And Below Waterfalls In Mountain Streams Of Virginia, Hannah Eisemann Macmillan
Assessing Populations Of Eastern Brook Trout (Salvelinus Fontinalis) Above And Below Waterfalls In Mountain Streams Of Virginia, Hannah Eisemann Macmillan
Masters Theses, 2010-2019
Anthropogenically driven factors, such as increasing temperature and sediment in valley streams, acidification of mountain streams, and the introduction of non-native trout, are restricting habitat suitable for healthy populations of eastern brook trout (Salvelinus fontinalis) throughout their native Appalachian range. Brook trout are important as predators of insects in mountain streams and as a favorite of anglers. It is crucial that remaining populations in sustainable habitats be identified and preserved. Waterfalls are geologic knickpoints preventing base-level lowering that create unique, stable landscapes above them, which may alleviate the temperature-productivity/acidity “habitat squeeze” for populations of brook trout and could …
An Acoustic Monitoring Method For Assessing River Dolphin Presence And Changes In The Context Of Anthropogenic Development, Charles A. Muirhead
An Acoustic Monitoring Method For Assessing River Dolphin Presence And Changes In The Context Of Anthropogenic Development, Charles A. Muirhead
Graduate Masters Theses
Populations of river dolphins throughout Asia are in decline as a direct result of intensified anthropogenic activity along river systems. Water development projects, land use change, contamination, and intensified fishing practices are known factors contributing to the probable extinction of the Yangtze river dolphin (Lipotes vexillifer) and declining populations of the South Asian river dolphin (Platanista gangetica spp.), Irrawady dolphin (Orcaella brevirostris), and finless porpoise (Neophocaena a. asiaeorientalis). Although not yet as extensive, river system development in South America is following a similar path as that of Asia, with impacts on dolphin species likely to follow. Currently, the Amazon river …
Conservation Of Freshwater Live-Bearing Fishes: Development Of Germplasm Repositories For Goodeids, Yue Liu
Conservation Of Freshwater Live-Bearing Fishes: Development Of Germplasm Repositories For Goodeids, Yue Liu
LSU Doctoral Dissertations
Fishes of the family Goodeidae are considered to be among the most imperiled taxa in the world. The goal of this project was to provide a foundation for development of sperm repositories for goodeids and to use them as a model to assist conservation programs for imperiled freshwater live-bearing fishes. Development of such repositories is challenging because of unusual reproductive characteristics of live-bearing fishes, such as sperm bundles, internal fertilization, and the bearing of live young. Standardized methods were established to evaluate quality-related attributes of sperm bundles. The different features between activation of free and bundled sperm were investigated and …

Increasing the size and number of marine protected areas (MPAs) is widely seen as a way to meet ambitious biodiversity and sustainable development goals. Yet, debate still exists on the effectiveness of MPAs in achieving ecological and societal objectives. Although the literature provides significant evidence of the ecological effects of MPAs within their boundaries, much remains to be learned about the ecological and social effects of MPAs on regional and seascape scales. Key to improving the effectiveness of MPAs, and ensuring that they achieve desired outcomes, will be better monitoring that includes ecological and social data collected inside and outside …
Evaluating Elasmobranch Bycatch And Shark Depredation In The Georgia Shrimp Fishery, Matthew M. Scanlon
Evaluating Elasmobranch Bycatch And Shark Depredation In The Georgia Shrimp Fishery, Matthew M. Scanlon
Electronic Theses and Dissertations
The Georgia shrimp fishery has seen a dramatic decrease in profit and productivity since the 1980’s due to a number of economic factors. Additional, yet undocumented, pressures on this fishery include interactions between foraging sharks with trawl gear. Fishermen report that sharks frequently bite nets in an attempt to prey on netted fish, resulting in large holes in the gear. Further elasmobranch interactions with trawl gear occur as bycatch; shrimp trawls represent nearly 100% of elasmobranch commercial bycatch in Georgia state waters, the species composition of which is largely unstudied. Shark interactions with nets were detailed through fishery-dependent observations on …
The Effect Of Size On Juvenile Green Sturgeon (Acipenser Medirostris) Behavior Near Water-Diversion Fish Screens, Jamilynn B. Poletto, Dennis E. Cocherell, Natalie Ho, Joseph J. Cech Jr., A. Peter Klimley, Nann A. Fangue
The Effect Of Size On Juvenile Green Sturgeon (Acipenser Medirostris) Behavior Near Water-Diversion Fish Screens, Jamilynn B. Poletto, Dennis E. Cocherell, Natalie Ho, Joseph J. Cech Jr., A. Peter Klimley, Nann A. Fangue
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Anthropogenic water management projects and facilities that alter the local and regional hydrology of riverine environments greatly influence the behavior, physiology, and survival of native fishes. To mitigate for losses of native fishes at these structures, many are outfitted with fish-exclusion screens to reduce entrainment. The effect of fish size and age on behavior near fish screens, however, is largely unknown. Therefore, we tested two size classes of juvenile green sturgeon (Acipenser medirostris; small, early juveniles: 9.2 ± 0.2 cm fork length [FL], 6.9 ± 0.3 g; intermediate juveniles: 18.8 ± 0.2 cm FL, 36.9 ± 0.8 g) …

Evaluating Habitat-Based Niche Requirements And Potential Recruitment Bottlenecks For Imperiled Bluehead Sucker (Catostomus Discobolus), Bryan C. Maloney
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Changes to rivers that alter physical and thermal habitat may cause fish population abundance to decline, due to fewer individuals maturing and entering the adult population. The Weber River has become highly degraded with many dams and diversions altering fish habitat, river volume, velocity, and temperature, and limiting movement between reaches. Bluehead suckers (Catostomus discobolus) occupy only 47% of their historical range and the genetically-distinct Weber River (northern UT) population is declining and contains few young, juvenile fish. My objectives were to determine whether spawning and rearing habitat available in the Weber River may be limiting bluehead sucker …
Body Shape Diversification Of Pecos Pupfish (Cyprinodon Pecosensis) On Varying Habitats As Evaluated By Geometric Morphometrics, Qianna Xu
Masters Theses & Specialist Projects
During the 19th and 20th centuries, alterations to the Pecos River in New Mexico and Texas, USA due to anthropogenic activities, including damning and river channelization, vast water extraction for irrigation, as well as pollution of associated habitats, have greatly impacted the fish fauna within the drainage. One of the endemic fish species, the Pecos pupfish (Cyprinodon pecosensis), might be the most affected. Historically abundant and widespread large populations have been disrupted and became a series of small isolated subpopulations that persist at a few highly fragmented habitats restricted to a small area in southern New Mexico. The connectivity among …

Protected Areas As Social-Ecological Systems: Perspectives From Resilience And Social-Ecological Systems Theory, Graeme S. Cumming, Craig R. Allen
Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications
Conservation biology and applied ecology increasingly recognize that natural resource management is both an outcome and a driver of social, economic, and ecological dynamics. Protected areas offer a fundamental approach to conserving ecosystems, but they are also social-ecological systems whose ecological management and sustainability are heavily influenced by people. This editorial, and the papers in the invited feature that it introduces, discuss three emerging themes in social-ecological systems approaches to understanding protected areas: (1) the resilience and sustainability of protected areas, including analyses of their internal dynamics, their effectiveness, and the resilience of the landscapes within which they occur; (2) …

Speyeria idalia populations have declined as much as 95 percent over the last three decades. Here we critically evaluate prairie habitat components along the Platte River in central Nebraska that S. idalia populations require in an effort to better inform conservation efforts. We utilized S. idalia count data from biological monitoring transects where vegetation, soils, land management, and flooding frequency data were also collected to describe the habitat constituents associated with S. idalia presence. We utilize comparative statistics, Pearson’s correlation analysis, and random forest analysis to model S. idalia habitat on land owned and managed by a small conservation NGO. …

Flight of the Freshwater Fish
The Hudson River provides for millions of people as a path for commercial and private transportation, a source of food and energy, and perhaps most importantly for many living in the tri-state area as a destination for recreation and relaxation. The most overlooked feature of the river is how the wildlife shows clear signs of a changing climate and rapid environmental response to the impacts of global warming on the river.
Entire populations of fish species in the lower Hudson have been forced to leave the river …

An Investigation Of Juvenile Alewife (Alosa Pseudoharengus) Habitat Use And Growth Using Natural Markers, Gregory Norman Labonte Ms
All Student Scholarship
This research attempts to connect patterns in growth and migration of an anadromous species. The goal of this research was to understand habitat movements and growth of juvenile alewives (Alosa pseudoharengus) in the Penobscot Estuary and Bay through the use of otolith microchemistry, otolith growth increments, and a laboratory stable isotope turnover study. Understanding the connection between growth and movement of juvenile alewives may lead to more accurate and sophisticated conservation and restoration methods for anadromous species.
