Pacific lamprey (Entosphenus tridentatus), an anadromous ectoparasite, faces several challenges during adult migration to spawning grounds. Developingmethods to address these challenges is critical to the success of ongoing conservation efforts. The challenges are diverse, and include anthropogenic alterations to the ecosystem resulting in loss of habitat, impassable barriers such as dams, climate change impacts, and altered predator fields. We conducted a behavioral study to understand how adult migrating Pacific lamprey respond to potential alarm cues: White Sturgeon (Acipenser transmontanus), human saliva, decayed Pacific lamprey, and river otter (Lontra canadensis). Research has shown that some species of lamprey can be guided …

Efforts to reverse declines in native grasslands benefit from agricultural policies that encourage private land conservation. The U.S. Department of Agriculture’s Conservation Reserve Program (CRP) improved conservation across landscapes but enrollment has declined. We used sequential exploratory mixed methods to compare landowner and conservation practitioners’ perceptions, evaluate perceived benefits, and identify potential improvements to CRP. Focus groups of practitioners informed a quantitative survey of landowners who had properties >160 total acres in Nebraska. Results suggest potential misalignment in perceptions between practitioners and landowners. Practitioners were concerned that conservation, especially of wildlife, was secondary to profit. But the majority of landowners …

In this article we summarize histories of nonlinear, complex interactions among societal, legal, and ecosystem dynamics in six North American water basins, as they respond to changing climate. These case studies were chosen to explore the conditions for emergence of adaptive governance in heavily regulated and developed social-ecological systems nested within a hierarchical governmental system. We summarize resilience assessments conducted in each system to provide a synthesis and reference by the other articles in this special feature. We also present a general framework used to evaluate the interactions between society and ecosystem regimes and the governance regimes chosen to mediate …

Population Structure, Connectivity, And Phylogeography Of Two Balistidae With High Potential For Larval Dispersal: Balistes Capriscus And Balistes Vetula, Luca Antoni
Dissertations
The gray triggerfish (Balistes capriscus) and the queen triggerfish (Balistes vetula) are two exploited reef fish distributed in tropical and temperate shelf waters of the Atlantic Ocean and the Mediterranean Sea. Both species are highly sedentary as adults but disperse pelagic larvae for extended periods of time potentially allowing connectivity across long distances under the action of oceanic currents. In this work population structure, phylogeography, and migration patterns were examined in the two species and contrasted with predictions of larval transport based on surface circulation data. A total of 1,017 gray triggerfish from twelve sampling localities …

Life History Of The Non-Native Invasive Red Lionfish (Pterois Volitans) In The Northern Gulf Of Mexico, Alexander Q. Fogg
Master's Theses
Invasive Red Lionfish (Pterois volitans) were first detected in the northern Gulf of Mexico (nGOM) in 2010 and since then their numbers have increased dramatically. From 2010 to 2015, more than 15,000 Red Lionfish were collected opportunistically from the nGOM for this study. Length and weight relationships differed significantly among ecoregions by sex and there was clear sexual dimorphism in size with males being larger and heavier. Red Lionfish age ranged from 0-4.5 years old and males achieved greater growth rate (K) and asymptotic maximum lengths (Linf) compared to females and these parameters were also different …

Growth Patterns And Size-Group Interactions In Hatchery-Reared Age-0 Lake Sturgeon, Joseph M. Susco
All NMU Master's Theses
Raising lake sturgeon (Acipenser fulvescens) in hatcheries is an important tool for rehabilitation and conservation, but is expensive. When hatchery sturgeon do not grow large enough before stocking, their odds of survival decline significantly and resources are wasted. We investigated the potential limiting effect of large lake sturgeon on the growth rate of smaller conspecifics housed in the same tank, and the possibility of increasing growth rates by separating individuals into different size classes. We also examined plasma cortisol levels of the different size classes over time as an indicator of stress levels, and levels of free plasma …

This paper reviews the circumstances that led to the collapse of the Pacific groundfish fishery and the steps that fishery managers took to curb over-harvesting and bring the fishery back to sustainability. Fishery managers utilized various management tools such as a vessel buyback program, regulatory mechanisms, and market strategies to improve the available data on the fishery, improve safety for fishermen, and reduce harvest rates and overcapitalization. By employing a diverse range of measures, managers developed a system by with they successfully balanced conservation objectives and minimized adverse impacts to fishing communities. Overcapitalization and overharvest continue to degrade the health …

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 …

Potential Influence Of A Marine Heatwave On Range Extensions Of Tropical Fishes In The Eastern Indian Ocean—Invaluable Contributions From Amateur Observers, Rodney C J Lenanton, Christopher E. Dowling, Kimberley A. Smith, David V. Fairclough, Gary Jackson
Fisheries Research Articles
Global changes to fish distributions are expected to continue in coming decades with predicted increases in ocean temperatures and the frequency of extreme climatic events. In the eastern Indian Ocean during the 2010/11 summer, sea surface temperatures 4–5 °C above average and an unseasonal, anomalously strong, Leeuwin Current (LC) triggered a “marine heatwave” along the west coast of Australia, with elevated water temperatures persisting for a further two years. Peak LC flows in summer/autumn transported pelagic early life history stages of summer-spawning coastal subtropical and tropical fishes southwards. This study examined whether the heatwave enabled the arrival, persistence and reproduction …

The freshwater mussel populations in the lower stretch of Big Walnut Creek in central Ohio have been found to vary along the run of the creek with the lowest population of mussels in the middle stretch. One possible cause for the decline is the presence of contaminants in the sediments of the creek. In this study, nine Sites along the creek were examined. At each Site, sediment samples from a pool region and two quadrants from where mussels were also studied (the area of interest) were collected, along with pseudo feces, which is the waste mussels produce as they filter …

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 …

Small-Scale Farming Of Sandfish (Holothuria Scabra) At Unguja Ukuu, Zanzibar, Claire Hacker
Independent Study Project (ISP) Collection
The biological and social components of sandfish farming were studied at Unguja Ukuu, Zanzibar. Measurement of temperature and depth, along with quadrat sampling of substrate and sea cucumbers, led to recommendations for future management of depth, biomass per area, disease and crabs, and substrate. Interviews revealed the role and potential benefits of sea cucumber farming for communities. Several barriers to, and complications with, the expansion of sea cucumber farming were also identified. This study provided information for improvement of this farm and hoped to spread knowledge of sandfish farming to Zanzibaris, who may benefit economically from the practice.

Zebrafish As A Model For Post-Traumatic Stress Disorder (Ptsd), Bernadette Johnson
Honors Theses
Post-traumatic stress disorder (PTSD) is a psychological disorder with limited treatment options. Molecular mechanisms that cause PTSD remain unclear due to a lack of viable animal models. Considering the behavioral similarities between zebrafish (Danio rerio) and humans, their social nature, and functional parallels between select brain regions, we hypothesized that zebrafish can demonstrate PTSD and that antioxidant treatment will prevent PTSD induction. To test this hypothesis, adult zebrafish were exposed to a traumatic event then were tested immediately and three weeks after the event. Traumatized fish exhibited non-social behavior, spending 7000 fold less time interacting with tank mates then their …

CCPO Publications
The commercially valuable Atlantic surfclam (Spisula solidissima) is harvested along the northeastern continental shelf of the United States. Its range has contracted and shifted north, driven by warmer bottom water temperatures. Declining landings per unit of effort (LPUE) in the Mid-Atlantic Bight (MAB) is one result. Declining stock abundance and LPUE suggest that overfishing may be occurring off New Jersey. A management strategy evaluation (MSE) for the Atlantic surfclam is implemented to evaluate rotating closures to enhance Atlantic surfclam productivity and increase fishery viability in the MAB. Active agents of the MSE model are individual fishing vessels with …
