Recreational Fishers’ Attitudes To Fisheries Management And Compliance, Karina L. Ryan, Clinton Syers, Kane Holtom, Timothy J. Green, Jeremy M. Lyle, Kate E. Stark, Sean R. Tracey

Fisheries Research Articles

Recreational fisheries policy decisions have social and ecological outcomes that depend on whether regulations are understood and meet expectations, which in turn enhances compliance. This study investigates perceptions of management and compliance among boat-based recreational fishers in Western Australia with consideration of demography (age, residence) and fishing behaviour (avidity, bioregion fished). Most respondents considered themselves to be informed about rules governing their fishing and there was strong support for current input and output controls, including area and seasonal closures and possession and size limits. There was less support for alternative regulations that are not currently in practice, such as annual …

Post-Harvest Processing Practices Of Small-Scale Fisherfolk From Rosario, Cavite, Philippines: Physicochemical And Microbiological Properties Of Tuyo, Abigail Ann Alano Ching, Myrna Benita Zamora Luna, Janice A. Ragaza

Biology Faculty Publications

Dried, salted fish (Sardinella spp.), locally known as tuyo, is a Filipino food staple. Pandawan fisherfolk consider tuyo processing as their main source of livelihood. This study determined the relation of post-harvest practices with the physicochemical and microbiological quality of tuyo. Tuyo processing involves receiving, washing, salting, rinsing, sun-drying, pressing, cooling, and packaging. Although the documented tuyo processing complied with the code of practice, processors needed to follow Good Manufacturing Practices. Moreover, tuyo had lower salt content (7.77-9.08 %NaCl), higher water activity (0.79-0.81), and aerobic plate count (7.82-8.36 log CFU/g) compared to national standards. Its yeast and mold count (3.58-3.66 …

A Decade Of Monitoring Reveals A Dynamic Fish Assemblage On A Substantial Artificial Reef In The Texas Gulf Of Mexico, David Hicks, Ethan T. Getz, Richard Kline, Carlos E. Cintra-Buenrostro

School of Earth, Environmental, & Marine Sciences Faculty Publications

Fish communities on artificial reefs have rarely been monitored over long periods to evaluate success of reef deployment. Here, we used roving diver surveys to assess changes in fish assemblages on a large, reefed vessel during 2008–2017. Multivariate analyses revealed a dynamic community that stabilized after 5 years. Species richness increased and species dominance decreased during 2008–2017. The fish community shifted toward reef-associated species such as hogfish and pufferfish. Species composition shifted, but trophic structure was relatively stable, which suggested that functional groups may not reflect larger community shifts. Our results indicate that fish communities on artificial reefs are temporally …

Effects Of Different Protein And Lipid Levels In Practical Diets For Yellowtail Snapper, Ocyurus Chrysurus (Bloch, 1971), Stephanie F. Velasquez, Leonardo Ibarra-Castro, Alexis Weldon, Donald Allen Davis

Biology Faculty Publications

Yellowtail snapper Ocyurus chrysurus has great potential as a production fish in aquaculture, yet there is very limited information on its nutritional requirements. To establish baseline data, two trials were conducted to evaluate the effects of dietary protein and lipid levels in practical diets on growth and protein retention. The first trial, conducted over 14 weeks, used a series of diets with varying levels of protein (36%, 40%, and 44%) and lipids (6%, 10%, and 14%). The second trial, conducted for 10 weeks, used a series of diets with 36% protein and scaled lipid levels (7%, 10%, 13%, and 16%). …

State Of The Fisheries: Status Reports Of The Fisheries And Aquatic Resources Of Western Australia 2023/24, Stephen J. Newman, Jenny Moore, Daniel J. Gaughan

Status Reports of the Fisheries and Aquatic Resources

This edition of the “State of the fisheries” continues the tradition of annually reporting on the status of exploited fish and their habitats in Western Australia. Critically, the reports provide overviews of the science outcomes that underpin management of fishing across the state.

Scientifically assessing the status of fish resources and potential impacts on ecosystems is inherently challenging; I acknowledge and thank the dedicated fisheries science teams and various support staff for again producing outstanding, robust scientific results that are summarised herein. I similarly acknowledge (i) the fisheries management team who use the science outcomes in policy development and to …

New Hampshire Residents' Perceptions Of Aquaculture Show Opportunities For Education, Anna Maccaroni, Emily Whitmore, Lindsey Williams

Carsey Publications

In this brief, authors Anna Maccaroni, Emily Whitmore, and Lindsey Williams discuss the results of a June 2024 statewide survey of New Hampshire residents to understand their perceptions of aquaculture. Conducted by the University of New Hampshire’s Survey Center on behalf of New Hampshire Sea Grant, participants were asked about their opinion of aquaculture in New Hampshire, how much they have read or heard about aquaculture, whether they are aware of aquaculture activity in New Hampshire, and how frequently they consume seafood products. The authors report that the majority of New Hampshire residents are unfamiliar with aquaculture and are not …

Analyzing The Catfish And Trout Competitiveness Trends And Potential Trade Within The Us And Global Aquaculture Industry: A Gravity Model Approach, Diana Marisol Amaya Discua

LSU Master's Theses

The United States is one of the major seafood product importers in the world. Despite the increases in global seafood and aquaculture consumption over the past decades, there is limited information on the trade dynamics of this sector. To address this gap, this study uses an augmented gravity model to evaluate the factors that have influenced catfish and trout imports into the United States. The analysis was conducted using the Poisson Pseudo Maximum Likelihood (PPML) estimator to address issues of heteroskedasticity, autocorrelation, and zero trade flows. The results highlight the importance of Gross Domestic Product (GDP) and exchange rates in …

Applying Data-Limited Assessment Methods To Charter Logbook Length Data, Brett Crisafulli, Sybrand Alex Hesp, David Fairclough, Emily A. Fisher, Paul D. Lewis, Jeffrey V. Norriss, Corey B. Wakefield, Fabian Trinnie, Stephen J. Newman

Fisheries Research Reports

Marine waters along the Western Australian coastline are characterised by low ecosystem productivity and high species diversity of fishes. With over 3,000 known species comprising estuarine, nearshore, demersal and pelagic fishes in the region, many contribute to important commercial and recreational fisheries (Lenanton et al. 1991; Molony et al. 2011; Newman et al. 2018). As it is logistically and economically infeasible to conduct intensive monitoring and high-level stock assessments of all exploited fish species in Western Australia, indicator species are used to assess the sustainability of suites of species of biological and ecological similarity, for optimal use of available resources …

Approaching A U.S. Regulatory Framework For Sporeless Seaweed Biotechnology, Gabriela Martinez, Terra Bowling, Catherine M. Janasie, Charlie Doering-Powell, Amalia Aruda Almada

William & Mary Environmental Law and Policy Review

Seaweed farming is the fastest-growing aquaculture sector in the United States. The development of sterile, selectively bred (sporeless) seaweed aims to support the economic viability of future large offshore seaweed operations and minimize the environmental risks of these operations to wild seaweed beds. Farmers have implemented analogous breeding techniques to control and enhance most terrestrial crops and common aquaculture products (e.g., oysters and carp). This Article draws from existing federal and state aquaculture policies to explore four pillars critical to a future sporeless seaweed regulatory framework: ensuring maintained sterility, tracing the geographic origin of seed, securing offshore permits, and facilitating …

On The Line And Online: Higher Non-Response To Web-Based Surveys Over-Represents Avid Recreational Fishers Compared With Telephone Surveys, Karina L. Ryan, Steve Taylor, Jeremy M. Lyle, Kate Stark, Sean R. Tracey

Fisheries Research Articles

Recreational fishing surveys have an important role in providing data to inform fisheries management. The selection of a contact method is an important and often challenging consideration that influences the potential for non-sampling errors that can result in unrepresentative data and biased estimates. Telephones are used for many off-site recreational fishing surveys, but widespread use of digital technology suggests that online surveys could be a viable alternative. We compared phone surveys with alternative online surveys using probability sampling from a licence database. Response rates were lower for online surveys (13%–26%) than phone surveys (97%–98%). The proportion of respondents who reported …

Psychological And Social Well-Being Of Bony Fishes In Zoos And Aquariums, Ronald G. Oldfield, Patrick Bonano

Animal Sentience

Research on the behaviour of animals in zoos has been conducted for decades, and observations have provided information that has improved the psychological and social well-being of animals. However, research on fishes in zoos and aquariums seems to be lacking. Here, we assess the current state of research on fishes in zoos and aquariums by surveying the peer-reviewed literature. Our assessment differs from previous surveys in that we examine the taxonomic classes Chondrichthyes (sharks and rays) and Osteichthyes (bony fishes) separately. Our survey finds that bony fishes have been drastically underrepresented in zoo journals, more drastically than chondrichthyans, revealing an …

Density-Dependence Inside A Marine Protected Area Increases Natural Mortality And Stunts The Growth Of A Spiny Lobster, Emma-Jade Tuffley, Simon De Lestang

Fisheries Research Articles

Sustainable fisheries management often requires the modelling of stocks under unfished conditions, when the influence of population densities on animal growth and mortality can be substantial. This can be especially true for species such as spiny rock lobster, which are very habitat specific. Using western rock lobster (Panulirus cygnus) tag-recapture data from adjacent and similar fished and unfished areas, the key life history parameters of natural mortality and growth were examined and compared under different population density scenarios. In an area representative of virgin biomass levels, lobsters exhibited reduced growth rates and a substantially higher rate of natural mortality …

Effects Of Revegetation Approaches On Wetland Plant Community Reassembly Under Hydrologic Extremes, Maddie Houde, Karin Kettenring

Browse all Datasets

Active revegetation is often necessary to recover native plant communities in disturbed or degraded wetlands. However, active revegetation has been pursued less in wetlands than other ecosystems and thus, there are few established best practices to guide implementation. Additionally, wetland revegetation is challenging due to dynamic hydrology becoming more extreme and high invasive plant propagule pressure that can limit native plant recruitment and favor invasive plant dominance. In this study, we tested the efficacy of varied revegetation approaches on native plant reassembly and invasion resistance in semi-arid wetlands subject to seasonal hydrologic fluctuations. In a Great Salt Lake wetland in …

Tracing Atlantic Sea Scallops Using Radio Frequency Identification (Rfid) Technology, Will Shoup, David Rudders, Jonathon Peros

Journal of Extension

Radio Frequency Identification (RFID) represents a technology that has the potential to enhance many aspects of the Atlantic sea scallop fishery. Driven by fishery management and market forces, fishery product traceability benefits fisheries managers, consumers, and fishermen. In order to demonstrate the capabilities of RFID technology in the scallop fishery, a solution is proposed that would help establish clear Chain of Custody (CoC) so that the scallop supply chain can be better documented. Implementation and acceptance of any new technology will hinge on effective communication and extension efforts that can leverage the multi-benefit aspects of adopting RFID into the fishery.

Pilbara Demersal Scalefish Resource Recovery Plan 2023- 2043 (Phase 1), Department Of Primary Industries And Regional Development, Western Australia

Fisheries Management Papers

The Pilbara Demersal Scalefish Resource (PDSR) includes over 60 demersal scalefish species. The resource is accessed by the Pilbara Trap Managed Fishery, Pilbara Fish Trawl (Interim) Managed Fishery, and the Pilbara Line Fishery (PTMF, PFTIMF & PLF respectively) as well as the recreational and charter fisheries.

The PDSR is managed in accordance with the North Coast Demersal Scalefish Resource Harvest Strategy (Harvest Strategy). The sustainability objectives of the PDSR are set out in the Harvest Strategy and monitored via the use of an indicator species approach, whereby the status of key species is considered representative of the status of the …
