Puerulus Settlement Forecasting In A Harvest Strategy Evaluation Of The Rock Lobster Fishery In South Australia, Richard Mcgarvey, Adrian Linnane, John E. Feenstra, Janet M. Matthews, Lachlan J. Mcleay, Annabel Jones, Kyriakos Toumazos, Simon De Lestang

Fisheries Research Articles

Harvest strategies are utilised in the management of fishery resources globally. Critical to their success is harvest strategy evaluation, whereby future performance is assessed through projection modelling. Using the observed relationship between a puerulus settlement index and model-estimated recruitment, we evaluated a southern rock lobster (Jasus edwardsii) harvest strategy in South Australia. Short-to-medium puerulus settlement recruitment forecasting was incorporated into future projections of catch, catch per unit effort, and percent unexploited egg production (%UEP) during 2019–2022. Observed values of indicators that closely aligned with projected outputs indicated that puerulus forecasting underpinned reliable evaluation of future fishery performance. A …

Walleye (Sander Vitreus) Do Not Exhibit An Aggregative Predatory Response To Larval White Sturgeon (Acipenser Transmontanus) In The Upper Columbia River In Lake Roosevelt, Washington, Seth A. Barr

EWU Masters Thesis Collection

Seasonal prey abundance can drive predatory fishes to aggregate in areas of high prey density. This project aimed to determine whether Walleye (Sander vitreus) exhibit an aggregative predation response to larval White Sturgeon (Acipenser transmontanus) drifts in the Lake Roosevelt system which is a reservoir of the Columbia River in Washington State. Populations of sturgeon are threatened worldwide, and are in need of conservation research. Walleye are a popular nonnative piscivorous game fish that were accidentally or illegally introduced to Lake Roosevelt in the 1950’s. Walleye in this study were obtained by gillnetting during White Sturgeon pre-spawn, peak spawn, and …

Improving Stream Connectivity In South Dakota, Colton Rainier Curtis

Electronic Theses and Dissertations

Stream connectivity is crucial for fish movement and genetic diversity in fragmented landscapes. Road-crossings often act as barriers, disrupting hydrology and isolating fish populations. The Southeast Aquatic Resources Partnership (SARP) has developed rapid road-crossing assessment protocols and tools to prioritize restoration projects. However, managers lack tools for planning, directing, and initiating roadcrossing assessments. Managers also require modeling approaches to effectively identify and monitor road-crossings across dynamic stream networks. Presented here is a case study offering a roadmap for effective implementation of collaborative road-crossing assessments and prioritization of remediation projects, alongside an exploration of predictive modeling approaches to identify problematic crossings …

Complex Dynamics Of Coral Gene Expression Responses To Low Ph Across Species, Veronica Z. Radice, Ana Martinez, Adina Paytan, Donald C. Potts, Daniel J. Barshis

Biological Sciences Faculty Publications

Coral capacity to tolerate low pH affects coral community composition and, ultimately, reef ecosystem function. Low pH submarine discharges (‘Ojo’; Yucatán, México) represent a natural laboratory to study plasticity and acclimatization to low pH in relation to ocean acidification. A previous >2‐year coral transplant experiment to ambient and low pH common garden sites revealed differential survivorship across species and sites, providing a framework to compare mechanistic responses to differential pH exposures. Here, we examined gene expression responses of transplants of three species of reef‐building corals (Porites astreoides, Porites porites and Siderastrea siderea) and their algal endosymbiont communities …

Evaluating The Utility Of Tracers To Characterize Environmental Dna Transport And Inform Detection Of Fishes In Small Streams, Gavin B. Bandy

Cal Poly Humboldt theses and projects

This study was motivated by the need to develop a noninvasive and highly sensitive monitoring tool for determining local occupancy of an endangered aquatic species To make inference into the occupancy of fishes within small stream sites, we developed a method to determine whether environmental DNA (eDNA) concentrations from a target species were elevated relative to a tracer, formulated to mimic eDNA and introduced at a single location. We examined patterns in the observed distribution of the tracer to account for the effects of site-specific transport processes and sampling on distributions of naturally occurring eDNA at small spatial scales (400 …

Cultivation Of A Commercially Important Macroalga (Ulva Sp) For Polyculture Research In Coastal Georgia, Kyle Mundy

Electronic Theses and Dissertations

The Georgia coast has shown great potential for large-scale oyster aquaculture, and the rate at which the sector has grown demands implementation of novel techniques to ensure sustainability and success in the face of climate change. One practice – integrated multi-trophic aquaculture (IMTA) or polyculture – is known to have positive effects on the health and quality of farmed organisms and the surrounding environment through low pH/alkalinity amelioration, while also being a unique and viable way for a farming operation to diversify its products. To date, there has been no such attempt at investigating or demonstrating macroalgae culture in Georgia. …

Population Demographics Of Channel Catfish In The Lower Wabash River, Valerie J. Thompson

Masters Theses

Inland fisheries are experiencing increasing demands due to anthropogenic stressors, especially within large river systems that support both recreational and commercial fisheries. Riverine species are sensitive to habitat degradation, species introductions, and exploitation, so continued monitoring and management of these communities are vital to maintain abundance and diversity within these systems. The North American catfish family, Ictaluridae, supports both recreational and commercial fisheries throughout the United States. Channel Catfish Ictalurus punctatus are heavily studied and managed compared to other sport catfishes in this family because of their economic and ecological significance.

Wastewater treatment plants (WWTPs) are a point source of pollution that have potentially damaging effects on downstream fish populations, including reduced growth and survival and reproductive complications. To examine these possible effects, fathead minnows were exposed to effluent of three wastewater treatment processes at the Charleston Wastewater Treatment Plant located in Charleston, Illinois. These three treatments included two secondary treatments, a biofilm treatment and an activated sludge treatment, and one tertiary U.V. treatment. Two trials took place during this project: an acute, two-week exposure trial, and a chronic 119 day exposure trial. Upon completion of each trial, fish were assessed …

Estimating Daily Growth Of Age-0 Channel Catfish In A Free-Flowing, Commercially Exploited Midwestern River, Kaleb B. Wood

Masters Theses

The larval stage in fishes is an important stage in the life history, as their survival dictates the ability of the population to sustain itself as an adult population. While there is a plethora of information available for juvenile and adult life stages of Channel Catfish (Ictalurus punctatus), very little is understood about their larval life stage. This study sought to determine overall density, growth rates, and size structure of cohorts of age-0 Channel Catfish during a study year on the Wabash River. In 2018, I sampled age-0 Channel Catfish using a benthic trawl from May to September. …

Investigating The Relationships Between Biotic And Abiotic Factors Affecting Migratory Behavior In Westslope Cutthroat Trout Within The Priest River System, Kyle M. Keenan

EWU Masters Thesis Collection

Numerous salmonid species demonstrate diverse life histories, encompassing both resident and migratory behaviors. Migratory life histories play a pivotal role in maintaining metapopulations for various reasons, facilitating genetic exchange between populations and yielding larger-sized females with increased fecundity relative to residents. This study took place in northern Idaho, within the lower Priest River system, which is highly susceptible to degrading habitat. Previous research has discovered this system as a significant contributor to migratory Westslope Cutthroat Trout (Oncorhynchus lewisi, WCT) in the Lake Pend Oreille and Priest River systems.

Living Among Wildlife: Elevating Human-Wildlife Interactions And Coexistence, Bridget Rebecca Murphy

Graduate Student Portfolios, Professional Papers, and Capstone Projects

After a semester of learning, both in class and in nature, my writing honed in further on this human-nature divide. To me, I see humans as part of nature – as we are mammals, animals, part of the food chain, biological beings no higher than others on our planet. We have simply constructed this false narrative around us within our societies, minds and media that embeds this division between us and nature, between us and wildlife. Humans have been managing, stewarding, living off and within landscapes for thousands of years. As time and technology evolved, a lot of people began …

A Year Of Wins For Farmed Animals, Lewis Bollard

General – Farm Animal Issues

Although the European Union shelved its ambitious farmed animal welfare reforms, there were other “wins” for farmed animals in 2023. There were 130 new corporate pledges to eliminate cages for laying hens and the worst abuses of broiler chickens. So far, over 1,000 corporate pledges have been fully implemented, and 39% of American hens, 60% of European hens, and 80% of British hens are cage-free, up from 6%, 41%, and 48%, respectively, a decade ago. The US Supreme Court upheld California’s Proposition 12, which bans the sale of eggs, pork, and veal from caged animals and their offspring in California. …

Status Survey Of Eight Rare Aquatic Macroinvertebrates In East Texas, Alexandra Randall

Biology Theses

Freshwater is essential to human existence. The health of each freshwater source is connected to the survival of pollution intolerant species of aquatic macroinvertebrates in the orders Ephemeroptera, Plecoptera, and Trichoptera (EPT taxa). A higher presence of EPT taxa equates to better water quality because their water bound larvae assist in maintaining clean freshwater environments and will not survive in highly polluted water. Human disruption to natural environments is causing increases in polluted freshwater, leading to decreases in the presence of EPT taxa. Texas Parks and Wildlife Department documentation shows major concern for the populations of eight EPT species of …
