Natural Resource System Size Can Be Used For Managing Recreational Use, Derek S. Kane, Kevin L. Pope, Keith D. Koupal, Mark A. Pegg, Christopher J. Chizinski, Mark A. Kaemingk

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Outdoor recreation provides societal benefits that are often measured by the amount of use natural resource systems receive. Still, the amount of resource use natural resource systems receive is often unknown or unstudied. Monitoring and quantifying resource use is often logistically difficult and costly but is paramount to optimize societal benefits. Identifying a simple and readily available metric that can indicate the quantity of recreational use of natural resource systems would benefit natural resource management. Using recreational angler participation data during an 11-year study period from 73 public waterbodies in Nebraska, USA, we developed a resource size-use model that demonstrates …

Fisheries Research Reports

In April 2022, the Department of Primary Industries and Regional Development (DPIRD, Department) convened an ecological risk assessment (ERA) of the fisheries that access the Western Rock Lobster Resource (Resource). ERAs are conducted by the Department as part of its Ecosystem Based Fisheries Management (EBFM) framework.

This report provides an overview of the Western Australian (WA) fisheries that access the Resource to support the ERA risk scoring process. The ERA considered the potential ecological impacts of the harvest of the Resource by all sectors, including the commercial fisheries; West Coast Rock Lobster Managed Fishery (WCRLMF) and South Coast Crustacean Managed …

Fish And Invertebrate Community And Trophic Structure In The Gulf Of Mexico Coastal Plains Watersheds Across Varying Hydrologic Connectivity., Erin Elizabeth Thayer

LSU Doctoral Dissertations

Subtropical Northern Gulf of Mexico coastal plains watersheds tend to have mild seasonal temperature, low topography, and fine, mostly homogenous substrate sizes; these watersheds may not follow fish and invertebrate community patterns predicted by established lotic paradigms because those paradigms tend to describe communities in either temperate or tropical regions. However, the bases of most generally accepted lotic paradigms involve evaluation of allochthonous and autochthonous contributions to lotic ecosystems via three hydrologic connectivity dimensions including vertical (hyporheic and shallow groundwater), lateral (floodplain), and longitudinal (upstream and downstream). My dissertation goals were to explore these three dimensions within Louisiana coastal plains …

Smart Drumlines Ineffective In Catching White Sharks In The High Energy Capes Region Of Western Australia: Acoustic Detections Confirm That Sharks Are Not Always Amenable To Capture, Stephen M. Taylor, Jason How, Michael J. Travers, Stephen J. Newman, Silas Mountford, Daniela Waltrick, Christopher E. Dowling, Ainslie M. Denham, Daniel J. Gaughan

Fisheries Research Articles

The management of human-shark interactions can benefit from the implementation of effective shark hazard mitigation measures. A Shark-Management-Alert-in-Real-Time (SMART) drumline trial in the Capes region of Western Australia was instigated after several serious incidents involving surfers and white sharks (Carcharodon carcharias). The project aimed to determine whether white sharks (target species), which were relocated after capture, remained offshore using satellite and acoustic tagging. Over a 27-month period, 352 fish were caught, 55% of which comprised tiger sharks (Galeocerdo cuvier). Ninety-one percent of animals were released alive in good condition. Only two white sharks were caught; both were relocated ≥ 1 …

Recommendations For Establishing A Market For Invasive Green Crabs In New England, Eve Fischer, Jesse Minor, Marissa Mcmahan

Student Scholarship

Green crabs are one of the most invasive marine species in the world. Their populations in New England have grown significantly due to climate change, increasing their environmental and socioeconomic impacts. Green crabs are voracious predators of soft shell clams, and have had a detrimental impact on the region’s valuable clam fisheries. They also prey on juvenile lobsters and other shellfish and compete with native crab species for resources. Green crabs burrow into and damage eelgrass beds, which are a vital habitat for many marine species and an important “blue carbon” sink. Due to their rapid rate of reproduction as …

Recreational Fishing For Western Rock Lobster: Estimates Of Participation, Effort And Catch In 2021/22, Claire B. Smallwood, Karina L. Ryan, Alissa C. Tate, Lucy J. Rudd

Fisheries Research Reports

The Western Rock Lobster (WRL) (Panulirus cygnus) is the most commonly caught Rock Lobster (RL) species in Western Australia. Catches from the commercial and recreational sectors are required to determine and monitor Total Allowable Commercial Catch (TACC), Total Allowable Recreational Catch (TARC) and proportion of Allowable Harvest Level (AHL) achieved. The TARC is set at 5% of the AHL and evaluated in the harvest strategy based on a 5-year average. Since 2018/19, data for the recreational sector have been collected using phone- recall surveys to provide estimates of participation, fishing effort and retained catch (by numbers) from recreational fishers who …

Roldan, Nemi Malhotra, Jong-Chin Huang, Olivia Erin M. Buenafe, Kelvin H. -C Chen, Shin-Shin Liang, Chung-Der Hsiao

Chemistry Faculty Publications

Ractopamine (RAC) is a synthetic phenethanolamine, β–adrenergic agonist used as a feed additive to develop leanness and increase feed conversion efficiency in different farm animals. While RAC has been authorized as a feed additive for pigs and cattle in a limited number of countries, a great majority of jurisdictions, including the European Union (EU), China, Russia, and Taiwan, have banned its use on safety grounds. RAC has been under long scientific and political discussion as a controversial antibiotic as a feed additive. Here, we will present significant information on RAC regarding its application, detection methods, conflicts, and legal divisions that …

Shore-Based Recreational Fishing In The Perth Metropolitan Area: 2022, Alissa Tate, Lucy Rudd, Claire B. Smallwood

Fisheries Research Reports

Recreational fishing is a popular activity in Western Australia (WA), occurring throughout the state from boats, and from a variety of natural and man-made structures along the shore. Ongoing monitoring of the shore-based recreational fishery is essential to assist with resource allocation, management evaluation and stock assessments for nearshore species. Especially for species such as Australian Herring and Southern Garfish which had management changes including a reduction in bag limit from 30 to 12 in 2015 and closure of Perth Metropolitan waters in 2017, respectively. An on-site roving creel survey to collect effort and catch data from shore fishers has …

Zoned Leasing Impact On Shellfish Aquaculture Industry Development, Rebekah Woodburn

All Theses And Dissertations

Shellfish aquaculture is a growing industry in the United States that supports many individuals and communities. An important step in establishing or growing a shellfish aquaculture operation is obtaining a lease in which to cultivate shellfish. While many states allow aquaculturists to find their own lease location, the often time-intensive and expensive process to have the lease approved and permitted can be a great barrier for new entrants to the industry. Zoned leasing is a way for state agencies to establish large areas and pre-approve them for shellfish aquaculture, then divide the areas into smaller parcels of leases to be …
