Three Newly Recorded Genera And Species Of Gobiid Fishes (Teleostei: Gobiidae) From The Dongsha Atoll (Pratas Islands), South China Sea, Shao-Liang Hsu, Ta-Kang Liu, Kwang-Tsao Shao, Kuan-Te Chen, I-Shiung Chen

Journal of Marine Science and Technology–Taiwan

Three newly recorded gobiid genera of coral-reef gobies have been collected and examined by scuba diving in the Dongsha Atoll, also known as the Pratas Islands, South China Sea. They are Feia Smith, 1959; Sueviota Winterbottom and Hoese, 1988; and Trimmatom Winterbottom and Emery, 1981. These three genera were formerly unrecorded in the Dongsha Atoll and all Taiwanese waters before this paper. One representing species was found for each gobiid genus. The diagnosis for these three newly recorded species and genera will be provided in this paper.

Imputation Of Missing Count Data Of Recreational Boat Retrievals From Remote Camera Surveys In The Perth Metropolitan Region, Western Australia, E. Afrifa-Yamoah, S.M Taylor, Cameron J. Desfosses, U. A. Mueller

Fisheries Research Reports

In Western Australia (WA), remote cameras have been used to monitor boating activity at boat ramps since 2006 to assist in ongoing recreational fishing surveys. These monitoring schemes are useful tools to validate boating activity (defined here as the number of retrievals) and to corroborate estimates of recreational fishing effort obtained from other surveys. This is because remote cameras (also referred to as digital cameras) can provide complete coverage (i.e. 24 hours, 365 days) of boating activities.

Marine fisheries in coastal ecosystems in many areas of the world have historically removed large-bodied individuals, potentially impairing ecosystem functioning and the long-term sustainability of fish populations. Reporting on size-based indicators that link to food-web structure can contribute to ecosystem-based management, but the application of these indicators over large (cross-ecosystem) geographical scales has been limited to either fisheries-dependent catch data or diver-based methods restricted to shallow waters (<20 m) that can misrepresent the abundance of large-bodied fished species. We obtained data on the body-size structure of 82 recreationally or commercially targeted marine demersal teleosts from 2904 deployments of baited remote underwater stereo-video (stereo-BRUV). Sampling was at up to 50 m depth and covered approximately 10,000 km of the continental shelf of Australia. Seascape relief, water depth, and human gravity (i.e., a proxy of human impacts) were the strongest predictors of the probability of occurrence of large fishes and the abundance of fishes above the minimum legal size of capture. No-take marine reserves had a positive effect on the abundance of fishes above legal size, although the effect varied across species groups. In contrast, sublegal fishes were best predicted by gradients in sea surface temperature (mean and variance). In areas of low human impact, large fishes were about three times more likely to be encountered and fishes of legal size were approximately five times more abundant. For conspicuous species groups with contrasting habitat, environmental, and biogeographic affinities, abundance of legal-size fishes typically declined as human impact increased. Our large-scale quantitative analyses highlight the combined importance of seascape complexity, regions with low human footprint, and no-take marine reserves in protecting large-bodied fishes across a broad range of species and ecosystem configurations.

Recognizing the imperative to evaluate species recovery and conservation impact, in 2012 the International Union for Conservation of Nature (IUCN) called for development of a “Green List of Species” (now the IUCN Green Status of Species). A draft Green Status framework for assessing species’ progress toward recovery, published in 2018, proposed 2 separate but interlinked components: a standardized method (i.e., measurement against benchmarks of species’ viability, functionality, and preimpact distribution) to determine current species recovery status (herein species recovery score) and application of that method to estimate past and potential future impacts of conservation based on 4 metrics ( …

A Large-Scale Experiment Finds No Evidence That A Seismic Survey Impacts A Demersal Fish Fauna, Mark G. Meekan, Conrad W. Speed, Robert D. Mccauley, Rebecca Fisher, Matthew J. Birt, Leanne M.

Fisheries Research Articles

Seismic surveys are used to locate oil and gas reserves below the seabed and can be a major source of noise in marine environments. Their effects on commercial fisheries are a subject of debate, with experimental studies often producing results that are difficult to interpret. We overcame these issues in a large-scale experiment that quantified the impacts of exposure to a commercial seismic source on an assemblage of tropical demersal fishes targeted by commercial fisheries on the North West Shelf of Western Australia. We show that there were no short-term (days) or long-term (months) effects of exposure on the composition, …

Fisheries Food Webs: Quantifying Habitat-Use, Trophic Structure, And Energetic Pathways In Coastal Tanzania, Mario Fernando Hernandez

LSU Doctoral Dissertations

Commercial and recreational fisheries are a valuable resource to millions of people around the world. Developing countries are particularly dependent on the revenue provided by locally harvested fish with total exports from these nations valued at $80 billion USD. For Tanzania, fisheries provide not only a source of revenue but an important source of protein with an estimated 25 to 30kg of fish consumed per person every year. There is no doubt that high fisheries production is critical to the well-being of millions of livelihoods along the Tanzanian coast. An important but poorly understood driver of fisheries production is the …

Effects Of Salinity On Eastern Oysters: Locating Lower-Salinity Tolerant Populations And Defining Resource Zones Suitable To Restoration, Fisheries, And Aquaculture., Lauren Swam

LSU Master's Theses

Eastern oysters (Crassostrea virginica) provide valuable ecosystem services and support a productive commercial industry in the northern Gulf of Mexico. Declining abundance from water quality changes and other factors drives development of management and restoration strategies focused on a comprehensive, metapopulation approach. Identifying oyster resource zones based on water quality combined with selective breeding of oysters adapted to specific conditions provides strategies to support aquaculture development and ensure resilient oyster populations and high production. Using 2015-2019 satellite-derived continuous salinity and temperature data for coastal Louisiana, this work created maps defining oyster resource zones supportive of (1) broodstock sanctuary …

Adding Value Through Sustainability: Incentivizing An Ecosystem Approach To Oyster Aquaculture In Maine, Samuel Feldman

All Theses And Dissertations

This study identified oyster farming practices that have the potential to increase the sustainability of Maine’s oyster industry while increasing its value. Practices aligned with the principles of the ecosystem approach to aquaculture were gleaned from semi-structured interviews and surveys of oyster farmers and their buyers. Themes from interview transcripts were developed using thematic analysis. Survey data was used to triangulate interview transcript data. As a result, sustainable oyster farming practices were identified that had direct and indirect connections to the value of Maine’s oysters. Practices with direct connections to increased oyster value included conducting and advertising actions of increased …

Investigating Larval Spillover From Oyster Aquaculture Through Geospatial Habitat Suitability Index Modeling: A Damariscotta River Estuary Case Study, Daniel F. Delago

All Theses And Dissertations

The eastern oyster (Crassostrea virginica) supports the ecological function of estuarine ecosystems by creating biogenic reef habitat (Purchon, 2013), and positively influencing coastal biogeochemistry in intertidal, and subtidal environments (Humphries et al., 2016; Ray and Fulweiler, 2020). As anthropogenic impacts continue to influence the health of marine environments globally (Halpern et al., 2008), oyster reef restoration is gaining increased attention as a means of maintaining the function of estuarine systems (Beck et al, 2011). Shellfish aquaculture has gained increased attention, contributing 21% of all aquaculture production globally (FAO 2020). Shellfish aquaculture provides a suite of social-ecological benefits while …

Adopting Principles Of Food Justice For Equitable Oyster Aquaculture Industry Development, Cristina Sandolo

All Theses And Dissertations

The mid-Atlantic region is experiencing a resurgence of oyster production, through both wild harvest and, more recently, aquaculture. While a historic, wild catch oyster fishery drove economic development of the region, the modern-day oyster industry is less intensive, more heavily managed, and is growing due to a growing aquaculture industry. While many Black watermen played critical roles in developing the historic wild-caught industry, barriers to advancement within the industry and to wealth accumulation in general prevented many from experiencing the full array of compensation, benefits, and legacy that the booming industry could have provided. Now, the modern-day oyster aquaculture industries …

Markedly Similar Growth And Longevity Of Green Jobfish Aprion Virescens Over An Expansive Geographic Range Between The Hawaiian Archipelago And The Eastern Indian Ocean, Joseph M. O'Malley, Corey B. Wakefield, Michael J. Kinney, Stephen J. Newman

Fisheries Research Articles

The Green Jobfish Aprion virescens supports important commercial, recreational, and subsistence fisheries throughout its Indo-Pacific range. Concerns with previous estimates of age and growth from fish in Hawaii, along with evidence of variability in these parameters from locations outside the Pacific Ocean, limits their reliability as input parameters for assessments of this species, particularly in Hawaii. Previously validated aging criterion were applied to fish collected from within the Hawaiian Archipelago (main Hawaiian Islands and Northwestern Hawaiian Islands) and the eastern Indian Ocean to provide length-at-age, growth, and longevity information for stock assessment and management purposes as well as to further …

The Status Of Spotted Seatrout (Cynoscion Nebulosus) As A Technologically Feasible Species For U.S. Marine Aquaculture, Reginald Blaylock, Eric Saillant, Angelos Apeitos, David Abrego, Paul Cason, Robert Vega

Faculty Publications

Culture models and facilities for large-scale, commercial production of popular Gulf of Mexico species are unavailable. The spotted seatrout (Cynoscion nebulosus) is one of the most popular recreational fishes in the Gulf of Mexico. Seatrout culture techniques were adapted from red drum (Sciaenops ocellatus) protocols developed in the 1970s. Broodstock husbandry, spawning, and extensive pond rearing techniques using fertilized and bloomed brackish ponds were well-established by the 1980s. By 2018, approximately 80 million 25–30-day old seatrout had been produced, mainly for stock enhancement. Cannibalism and poor nutrition hindered intensive tank culture. Between 2005 and 2015, an …

First Data On Aquaculture Of The Tripletail, Lobotes Surinamensis, A Promising Candidate Species For U.S. Marine Aquaculture, Eric Saillant, Nicholas Adams, Jason T. Lemus, James S. Franks, Yonathan Zohar, John Stubblefield, Christopher Manley

Faculty Publications

The Tripletail, Lobotes surinamensis, is a warm-water pelagic fish that is increasingly targeted by U.S. anglers. The superior quality of Tripletail flesh coupled with the lack of domestic commercial fisheries stimulated interests to develop aquaculture of this species. In this work, photo-thermal conditioning of captive-held broodstocks promoted maturation in females, but spontaneous spawning was not observed. GnRHa slow-release implants induced ovulation in late vitellogenic females but fertility remained below 10% when GnRHa was administered alone. However, spawns with high fertility (up to 85%) were obtained when a dopamine antagonist was administered in conjunction with GnRHa implants indicating dopamine inhibition …

Marine reserves are a key tool for the conservation of marine biodiversity, yet only ~2.5% of the world's oceans are protected. The integration of marine reserves into connected networks representing all habitats has been encouraged by international agreements, yet the benefits of this design has not been tested empirically. Australia has one of the largest systems of marine reserves, providing a rare opportunity to assess how connectivity influences conservation success. An Australia-wide dataset was collected using baited remote underwater video systems deployed across a depth range from 0 to 100 m to assess the effectiveness of marine reserves for protecting …
