Scientifically Defensible Fish Conservation And Recovery Plans: Addressing Diffuse Threats And Developing Rigorous Adaptive Management Plans, Kathleen G. Maas-Hebner, Carl B. Schreck, Robert M. Hughes, J. Alan Yeakley, Nancy Molina
Environmental Science and Management Faculty Publications and Presentations
We discuss the importance of addressing diffuse threats to long-term species and habitat viability in fish conservation and recovery planning. In the Pacific Northwest, USA, salmonid management plans have typically focused on degraded freshwater habitat, dams, fish passage, harvest rates, and hatchery releases. However, such plans inadequately address threats related to human population and economic growth, intra- and interspecific competition, and changes in climate, ocean, and estuarine conditions. Based on reviews conducted on eight conservation and/or recovery plans, we found that though threats resulting from such changes are difficult to model and/or predict, they are especially important for wide-ranging diadromous …

Design Of An Aquaponics System, Jesse Birsinger
BioResource and Agricultural Engineering
This Senior Project discusses the design, cost analysis, and evaluation of an aquaponics system. The system incorporates aquaculture and hydroponics to create a source of fish protein and various crops. The system was sized based off a minimum requirement of pounds of fish available per week. The system designed is capable of generating 2080 pounds of catfish, and 16,000 pounds of produce annually. The first year of operation the system will operate at a loss due to the significant cost of the components of the system, however, the project is projected to generate a minimum stream of revenue of $10,600 …

Ménage À Trois In The Atlantic Brief Squid (Lolliguncula Brevis): Prior Presence Affects Mate Choice, Rachel A. Schlessinger
Theses and Dissertations
Lolliguncula brevis given prior presence experienced a significantly greater number of contacts with opposite sex squid than rivals. Males given prior presence also spent significantly more time in proximity to females than rivals. This suggests that for both female and male Atlantic brief squid, having prior presence influences mating behavior.
Rapid Lateral Extraction Of Otoliths That Maintains The Integrity Of Fish Product To Improve Access To Catches And Reduce Potential Sampling Biases,

Rapid Lateral Extraction Of Otoliths That Maintains The Integrity Of Fish Product To Improve Access To Catches And Reduce Potential Sampling Biases, Corey B. Wakefield, Dion K. Boddington, Stephen J. Davies
Fisheries Research Articles
The capacity to sample otoliths of fish from commercial, recreational, artisanal or subsistence catches can be constrained if the dissection process results in alterations to their external appearance and thus reduces its value and/or shelf life. There can also be significant biases incorporated into the collection of otolith samples if access is only granted relative to the size of the fish (i.e. if smaller fish are sold whole). To reduce such limitations, we herein describe a rapid and simple method of lateral otolith extraction that maintains the integrity of the fish product, and thus reduces potential biases in sample …

The Effect Of Water Quality On The Survival And Fitness Of Brook Trout (Salvelinus Fontinalis) Eggs, Alevins And Fry In Aquaculture And Deep Springs Along The South River In Waynesboro, Va, Thomas D. Teears
Masters Theses, 2010-2019
Brook trout populations have been extirpated in many Virginia streams due to poor water quality thus establishing populations of brook trout for recreational fishing is an important priority of fisheries management. The ability of a stream to protect developing brook trout (Salvelinus fontinalis) eggs and larval fish from adverse effects from acidification and metal toxicity as well as provide needed minerals such as magnesium (Mg2+) and calcium (Ca2+) for early-stage development is controlled primarily by geology, which influences water hardness and acid-neutralizing capacity (ANC). The focus of this research was on the effects of …

Assessment Of American White Pelican Predation And Reproductive Success Of Walleye In The Tamarac River, Mn, Jake Graham
Biology Graduate Theses
The Tamarac River is a major tributary of the Red Lakes MN, which provides an economically important multispecies fishery. The river experiences spring spawning migrations of northern pike, walleye, and white suckers. However, limited data exists related to reproductive success of fishes in the river. Furthermore, in the previous decade large congregations of American white pelicans (AWPE) have been observed using the Tamarac River as a foraging ground each spring. Assessing reproductive success of fishes in the Tamarac River provides a more holistic understanding of fish ecology in the river and the importance of the Tamarac River to the Red …
Impacts To Phytoplankton After The Establishment Of Quagga Mussels In Lake Mead, Nevada,

University of Nevada, Las Vegas
Impacts To Phytoplankton After The Establishment Of Quagga Mussels In Lake Mead, Nevada, Warren Bruce Turkett
UNLV Theses, Dissertations, Professional Papers, and Capstones
Quagga mussels (Dreissena rostriformis bugensis) are an invasive species that were discovered in Lake Mead in January of 2007, and rapidly spread throughout the lake. Quagga mussels are about the size of a fingernail, but are known to clog pipes, damage infrastructure and alter ecosystems. In large numbers, mussels can have a dramatic impact on an ecosystem by reducing the phytoplankton and potentially increasing toxin producing cyanobacteria. This research analyzed data collected from three separate basins in Lake Mead to determine if water quality characteristics that are commonly impacted by invasive mussels have changed. Transparency, chlorophyll-a, phytoplankton and zooplankton samples …

The Use Of Marine Aquaculture Solid Waste For Nursery Production Of The Salt Marsh Plants Spartina Alterniflora And Juncus Roemerianus, Heather M. Joesting, Reginald B. Blaylock, Patrick Biber, Andrew Ray
Faculty Publications
Recent technological advances in marine shrimp and finfish aquaculture alleviate many of the environmental risks associated with traditional aquaculture, but challenges remain in cost-effective waste management. Liquid effluent from freshwater aquaculture systems has been shown to be effective in agricultural crop production (i.e., aquaponics), but few studies have explored the potential for reuse of marine aquaculture effluent, particularly the solid fraction. The purpose of this study was to investigate the use of marine aquaculture solid waste as a nutrient source for the nursery production of two salt tolerant plants commonly used in coastal salt marsh restoration, Spartina alterniflora (smooth cordgrass) …

Now Hear This! Orientation And Behavioral Responses Of Hatchling Loggerhead Sea Turtles, Caretta Caretta, To Environmental Acoustic Cues, Bethany Holtz
Celebration
Although the visual and geologic orientation cues utilized by sea turtle hatchlings during seafinding, when they move from the nest to the sea after hatching, have been well studied, the potential for auditory stimuli to act as an orientation cue has not been well explored. Over the past several decades our knowledge of the auditory capacity of sea turtles has increased greatly, yet little is known about the biological significance of this sensory ability. To investigate whether hatchlings can use ocean sounds during seafinding, we measured the behavioral responses of hatchling loggerhead sea turtles (Caretta caretta) collected from nesting beaches …
Since Time Immemorial: The Decline Of Columbia River Basin Salmon,

Since Time Immemorial: The Decline Of Columbia River Basin Salmon, Samuel J. Levin
Young Historians Conference
Since Time Immemorial: The Decline of Columbia River Basin Salmon studies the near extinction of what has been historically the world’s largest salmon population. By examining the issue systemically, my paper reveals that the environmental misjudgments that have brought the salmon so near extinction are not isolated, but rather are the product of cultural trends. A study of these misjudgments reveals a culture within the Columbia Basin that has, since the mid-19th century, sought expansion for expansion’s sake and valued short-term wealth over long-term sustainability. My paper illustrates how his philosophy has guided and continues to guide Columbia Basin …

Bioeconomic Evaluation Of The Tiger Shrimp (Penaeus Monodon) Industry In Tra Vinh Province, Vietnam, Hieu Truong Khac, Hong Hue Tran Thi Phuong, Cheng Ting Huang, Sha Miao
Journal of Marine Science and Technology–Taiwan
Analysis of costs and returns for the tiger shrimp farming industry in Tra Vinh Province, Vietnam was carried out by considering different production scales. The production scale influenced not only the cost but also the profitability. Through the results of multivariate statistical analyses, this study showed that the production cost, benefit and earning capacity varied from extensive to semi-intensive and finally to intensive systems. By means of Cobb-Douglas production function analysis, it is revealed that net revenue from increasing the production scale would increase if the input intensities of the fixed, seed and feed costs rose. More investment should be …
