Resource Assessment Report No. 8: Pilbara Prawn Resource - 2024 Assessment, Inigo Koefoed, Rachel Marks, Scott Evans, Sharon Wilkin, Jason How

Resource Assessment Reports

The Pilbara Prawn Resource (Resource) is accessed by three managed commercial fisheries; the Exmouth Gulf Prawn Managed Fishery (EGPMF), the Onslow Prawn Managed Fishery (OPMF) and the Nickol Bay Prawn Managed Fishery (NBPMF). All three fisheries are managed under effort controls, with the EGPMF and OPMF targeting brown tiger prawns (BTP; Penaeus esculentus), western king prawns (WKP; Penaeus latisulcatus), blue endeavour prawns (BEP; Metapenaeus endeavouri), and lesser quantities of banana prawns (Penaeus merguiensis). The NBPMF primarily targets banana prawns while also catching BTP, WKP, and BEP in lower numbers. These fisheries are situated adjacent to one another along the Pilbara …

Resource Assessment Report No. 7: Shark Bay Invertebrate Resource - 2024 Assessment, Jason How, Inigo Koefoed, Rachel Marks, Scott E. Evans, Sharon Wilkin

Resource Assessment Reports

The Shark Bay Invertebrate Resource (Resource) is accessed by three managed commercial fisheries; the Shark Bay Prawn Managed Fishery (SBPMF), the Shark Bay Scallop Managed Fishery (SBSMF) and the Shark Bay Blue Swimmer Crab Managed Fishery (SBCMF). Additionally, blue swimmer crabs are taken by recreational fishers through a variety of methods, though the overall level of boat-based catch is relatively low (~ 7.8 t). The SBSMF and SBCMF fisheries are quota managed and primarily retain their target species of scallops and crabs, respectively. The SBPMF is an effort-managed fishery that targets brown tiger prawns (BTP; Penaeus esculentus) and western king …

Distribution Of Mussels In Tributary Systems Of The Lower Ouachita River Watershed, Zach R. Crain

ATU Theses and Dissertations 2021 - Present

Freshwater mussel communities in small tributary streams are poorly documented in Arkansas, limiting the understanding of how diversity is structured across river networks. To address this data gap, we surveyed 147 sites across five previously unsurveyed watersheds in the South-Central Plains Ecoregion (SCPE). We sampled 5,473 individuals representing 17 species, including four Arkansas Species of Greatest Conservation Need (SGCN). We evaluated patterns in community variation utilizing β-diversity based on both presence-absence and abundance data. Overall turnover (βsor and Bray) was partitioned into replacement (βsim and BrayBal) and nestedness (βsne and BrayGra) components. Replacement and nestedness each drove turnover in two …

Assessing The Conservation Needs Of Native Texas Crayfish Species Through Distribution Analysis And Species Distribution Modeling, Elizabeth J. Croft

Biology Theses

Crayfish have essential roles in ecosystems because they are ecosystem engineers and keystone species. However, crayfish species are threatened by degradation and loss of habitats, introduction of invasive species, and high levels of endemism. Texas provides no legal protections for crayfish, despite its large number of species and endemics in the state. The overall goal of this study is to clarify the distributions of native Texas crayfish species using literature records, citizens science, and field sampling data, and highlight species in need of more conservation research. Occurrence records from all collected data were combined to visualize the distributions of species …

Fisheries Management Paper No. 313: Western Australian Statewide Small Pelagic Scalefish Resource Harvest Strategy, Department Of Primary Industries And Regional Development, Western Australia

Fisheries Management Papers

Harvest strategies for Western Australia’s (WA) aquatic resources are formal documents developed by the Department of Primary Industries and Regional Development (DPIRD, the Department) to support decision-making processes that ensure the outcomes are consistent with the principles of Ecologically Sustainable Development (ESD; Fletcher 2002a) and Ecosystem Based Fisheries Management (EBFM; Fletcher et al. 2012).

Harvest strategies are a key component of all contemporary fishery management systems and a requirement for certification under the Marine Stewardship Council (MSC; Marine Stewardship Council 2018). The objectives of ESD are reflected in the objects of the Fish Resources Management Act 1994 (FRMA).

This Statewide …

Acute Effects Of The Psychoactive Pollutant Fluoxetine On The Antipredator Behavior Of The Gulf Killifish (Fundulus Grandis), Semyra Reus

Honors Theses

Pharmaceutical contaminants are increasingly prevalent in aquatic environments, yet their sublethal effects on ecologically relevant behaviors remain poorly understood, particularly in estuarine systems. Selective serotonin reuptake inhibitors (SSRIs), such as fluoxetine, are of particular concern due to the conserved role of serotonin in regulating behavior across vertebrates. Here, we investigated how acute exposure to environmentally relevant concentrations of fluoxetine influences anti-predator behavior in Gulf killifish (Fundulus grandis), a key estuarine fish commonly found in saltmarsh habitats. Killifish were exposed to control (0 ng/L), low (17.8 ng/L), and high (596 ng/L) fluoxetine concentrations and subsequently tested in the presence …

Gaining Mussel: Evaluating Reintroduction Success Of Native Freshwater Mussels In Nebraska And Eastern Wyoming, Travis A. Moore

School of Natural Resources: Dissertations, Theses, and Student Research

Freshwater mussels are one of the most imperiled groups of organisms in North America, with over two-thirds of species considered threatened, endangered, or of special concern. These long-lived bivalves are essential to stream ecosystems, acting as filter feeders that improve water quality and as indicators of aquatic health. In Nebraska and Wyoming, native mussel populations have declined sharply due to habitat modification, pollution, and reduced connectivity. Two species of particular concern are the Plain Pocketbook Lampsilis cardium, listed as Tier I at-risk in Nebraska, and the Fatmucket Lampsilis siliquoidea, a Tier II at-risk species. In response, state agencies …

Developing An Independent Shallow-Water Survey For The Western Rock Lobster Fishery: Tracking Pre-Recruitment Abundance And Habitat Change, Lucy Rudd, Simon De Lestang, Owen Young, Benjamin Hebiton

Fisheries Research Reports

Background

Puerulus settlement has proven to be a good forecaster of legal recruitment of Western Rock Lobster entering into the commercial and recreational fisheries. However, in 2011, this relationship broke down, with average puerulus settlement levels not being reflected in commercial catch rates four years later. Some northern areas showed unexpectedly low catch rates, while other southern areas showed unexpectedly high catch rates. Since this change followed the 2011 marine heatwave, it was assumed that this event changed some component(s) which were important to the growth and survival of juvenile lobsters. It was determined that a better understanding of this …

Feeding Ecology In Coastal Systems, Randi L. Cannon

Graduate Theses and Dissertations (2019 - present)

Oysters (Crassostrea virginica) are critical foundation species in estuaries, providing numerous ecological and economic benefits. However, oyster populations have diminished worldwide. Effective oyster restoration and aquaculture require a mechanistic understanding of the physiological and environmental factors that govern oyster feeding, growth, and resilience under changing coastal conditions. We investigated how oyster ploidy and environmental conditions influenced oyster feeding and investigated how changes in abiotic conditions affected behavioral performance of oyster drills (Stramonita spp.), a key oyster predator. To better understand feeding responses and behaviors of both predator and prey we 1) used in-situ filter feeding assays to determine if feeding …

Enhancing Walleye (Ogaa) Recruitment: Evaluating Assisted Reproduction As A Mitigation Strategy, Douglass Keiser

Biology Graduate Theses

Over the past several decades, cold- and cool-water fish populations across the Upper Midwest, including Minnesota and Wisconsin, have shown troubling signs of decline. Among the most affected is the walleye/Ogaa (Sander vitreus), a species deeply embedded in the ecological balance, cultural identity, and economic vitality of the region, and central to the lifeways, treaty-reserved rights, and resource stewardship of Tribal Nations, including Ojibwe communities across the Upper Midwest. Despite ongoing stocking efforts and harvest regulations, many lake systems have experienced persistent declines in natural recruitment, prompting resource agencies to investigate the underlying causes. One such system is …

Assessment Of Goose-Beaked Whale Responsesto Mid-Frequency Active Sonar Usinga Hierarchical Hidden Markov Model, Stacy L. De Ruiter, Erin A. Falcone, Shannon N. Coates, Brenda K. Rone, David A. Sweeney, Karin A. Dolan, Susan M. Jarvis, Russel D. Andrews, Stephanie L. Watwood, Gregory S. Schorr

University Faculty Publications and Creative Works

Background

Acoustic disturbance is increasingly recognized as an ecological concern, particularly at sea. In light of marine mammal stranding events associated with use of naval mid-frequency active sonar (MFAS), which often involve goose-beaked whales (Ziphius cavirostris), research has sought to detect and characterize Ziphius behavioral responses to MFAS.

Methods

We deployed Sound and Motion Recording and Telemetry (SMRT) tags on 13 Ziphius in the Southern California Bight. The study area includes the United States Navy’s Southern California Anti-submarine Warfare Range (SOAR), and deployments overlapped temporally with training exercises including MFAS use. We used hierarchical hidden Markov models (HHMMs), which provided …

Comprehensive Temporal, Spatial, And Environmental Analysis Of Arkansas Tournament Information Program (Atip) Data With A Lake Dardanelle Case Study., Jeffrey G. Phillips

ATU Scholars Symposium

The Arkansas Game and Fish Commission (AGFC) established the Arkansas Tournament Information Program (ATIP) in 1990 to provide a long-term, standardized dataset to describe Black Bass (Micropterus spp.) tournament outcomes, angler performance, and fish size structures across Arkansas, yet most of its analytical potential has not been fully explored beyond yearly summary reports. This project will use ATIP data from 1990 to 2027 and a biological case study from Lake Dardanelle to evaluate long-term trends, compare lake-specific performance, identify environmental drivers of tournament success, access how well tournament data represents true Black Bass populations, and create an “average” year benchmark …

Assessing The Effect Of A Human-Made Reservoir On The Mussel Community In Caney Creek, Trakker Estes

ATU Scholars Symposium

Freshwater mussels are one of the most threatened taxonomic groups globally, with less than 32% of North American taxa considered secure. In Arkansas, over half of the state’s 85 species are endangered, threatened, or of special concern. Small impoundments may contribute to these declines through reduced hydrological connectivity and the resulting decline of fish community movement. This study examines the effects of Tri-County Lake, a small impoundment of Caney Creek in southern Arkansas, on mussel abundance and diversity. In total, eight sites were surveyed upstream, within, and downstream of the impoundment across various habitat types. A timed-search approach utilizing scuba …

Teeth That Tell Time: Elemental Analysis From Shark Teeth, Gisele-Elizabeth Perez, David Turner

Research Papers

Sharks (Chondrichthyes) have hunted in the oceans for over 400 million years, their teeth leaving history behind, constantly becoming a part of the fossilization process (Worm et al. 2013). Their survival throughout 5 major extinctions is due to their ability to adapt easily with slow metabolism, a wide range of diet, and an efficient physiology. Shark teeth are vital to the hunting and consumption of their prey, making it a point for scientists to study them. Their tooth minerals contain fluorapatite in their enameloid, and dentin in the “root” of the tooth, with extinct species containing dentin and hydroxyapatite in …

Mapping Sensory Landscapes: Distribution And Arrangement Of The Anterior Lateral Line System In Texas Catfish, Tatiana Flores, Ruben Tovar

Research Papers

Fish have a system of sensory organs known as the lateral line system. This system contains numerous mechanoreceptive neuromasts and electroreceptive ampullary organs (Northcutt et al, 2000). Neuromasts are small, hair-like structures located within canals in the lateral line system just under the fish’s skin and are open to the environment through small pores visible on its skin (Parker, 2025). Water flows into these canals through the pores which stimulates the sensitive hair cells, resulting in electrical signals sent to the fish’s brain. The brain interprets these signals and creates “images” of the fish’s surroundings, helping it to see even …

Assessing The Influence Of Temperature And Water Level On Gill Disease In Goldfish, Moses Elijah Cadawas, Emmalie Turner, Darlene Panvini

SPARK Symposium Presentations

Gill disease in fish is a strong biological indicator of water quality and environmental stress. These diseases are commonly caused by bacterial or parasitic infections that target gill tissues and can lead to severe physiological impairment and ultimately mortality. Several environmental factors, including water level and temperature, play a critical role in determining fish susceptibility to these infections. Changes in these conditions can act as stressors that weaken immune defenses and promote pathogen proliferation. This study aimed to evaluate the relative impact of environmental stressors on the development of gill-associated disease in Carassius auratus (goldfish) under controlled conditions. Following exposure …
