Dietary Shifts And The Need For Increased Sustainability Approaches In The Global Aquaculture Seafood System, Darien D. Mizuta

VIMS Articles

Recent shifts in the global dietary preferences have indicated the fast-growing choice for plant-based, or meat-reduced diets. Among the motivations for such choices, which are increasingly advocated by nations and environmental institutions, is the major concern with global environmental sustainability and impacts of food production systems. Incontestably, the animal food source industry is extremely diverse, and seafood production through the aquaculture value chain remains unfamiliar to key stakeholders possibly leading to an uncomprehensive view and often biased perception of the farming industry within the environmental context. Accordingly, I discuss the importance of seafood production systems, such as the fastest seafood …

The Sociocultural Significance Of Maine's Oyster Based On Media Coverage Analysis, Syeira Clark

Honors College

Throughout the last decade, the oyster aquaculture industry in Maine has boomed, with 6 million pounds of oysters being harvested in 2021, about the amount that was harvested in 2016 (Cough, 2022). According to the founders of the Maine Oyster Trail, there are over 150 oyster farms currently operating on Maine’s coast, which is about twice as many as there were in 2016 (Maine Sea Grant). With this boom in the industry has come a wave of opportunity, as well as news coverage about the shellfish. This study examines the socio-cultural significance to the state of Maine. While the oyster …

Aquaculture In Africa: Aquatic Animal Welfare, Impact On The Environment And The Sustainability Of The Sector, Mwenda M. Mbaka, Janice H. Cox, Stephen Ronan

Aquaculture

The African aquaculture sector recorded the fastest growth in the world between 2006-2018, averaging 10% or more, and is expected to partially fill the growing fish supply-demand gap up to 2063. In 2018, there were about 1.2 million aquafarmers across the continent, an increase from 920 thousand in 2014. According to the African Development Bank, expansion of aquaculture in Africa is hampered by "the overwhelming predominance of tilapia farming, which relies heavily on the production of fingerlings from a limited number of genetically improved strains that are resistant to the many diseases affecting this species, and on the production of …

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 …

Abundance Of Shell-Boring Polychaete Worms And Other Fouling Organisms In Aquacultured Oysters From Maine Used For Reef Restoration In Great Bay, Nh, Haleigh Wright

Honors College

Restoration projects on the oyster reefs in Great Bay, NH have been active since 2009 with the most recent involving the transfer of oysters from Maine oyster farms into the Bay. In an attempt to prevent the transfer of non-native species from oyster farms to the reefs, samples of oysters from each farm were inspected for shell-boring polychaete infestations. Polydora websteri, a common shell-boring species worldwide, was in high abundance in reference samples from oyster farms in Great Bay and in samples from the restoration grounds, themselves. A second shell-boring species, provisionally identified as P. onagawaensis, is present on oyster …

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 …

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 …

Fishing And Rural Livelihood: A Philippine Context, Rosalina Palanca-Tan, Sheila Bongat-Bayog

Economics Department Faculty Publications

The Municipality of Lake Sebu in Mindanao; Philippines offers various opportunities for income-generating fishing activities with its abundant surface water bodies. Lake Sebu is particularly known for good quality tilapia; farmed in fish cages. This study employed primary data collection methods; namely key informant interview; focus group discussion and a comprehensive livelihood household survey to assess the conditions and problems constraining fishing households in Lake Sebu. The study found that fishing-related benefits were mainly derived from aquaculture. Capture fisheries are essentially very small-scale; low gear open fishing done by local fisher folk that generates only subsistence income. Local residents are …

Economic Vulnerabilities Of Fishing-Dependent Households Around Laguna Lake, Philippines, Rosalina Palanca-Tan

Economics Department Faculty Publications

The study characterizes the mainly subsistence fishing communities surrounding Laguna Lake and provides empirical evidence of the economic deprivation that they are experiencing using survey data. Following a multi-dimensional approach, the paper focuses on consumption expenditures as the prime indicator of economic well-being – together with assets ownership, financial behavior, and social engagements. Regression analyses are conducted to identify the factors underlying consumption and to determine how different forms of household capital (physical, financial, and social) and fishing activities affect the capacity to generate income or livelihood. The study finds that: 1) food consumption (mainly rice) accounts for half of …

Biotechnological Application In Aquaculture And Its Sustainability Constraints, Olaganathan Rajee, Tang Kar Mun Alicia

Publications

The valuable nutritional and biochemical properties have made fisheries products one of the most vital high-quality protein sources for human consumption. Aquaculture has become the great alternative to substitute wild catches when the yield from fishing are no longer sufficient to sustain the massive food demand of the human population which is constantly burgeoning. However, aquaculture requires multidisciplinary approaches with holistic and environmental-friendly management measures to ensure its long term success and sustainability. Biotechnological applications have enhanced the effectiveness and cost-efficiencies of aquaculture by augmenting the productivity of aquaculture to meet global needs. Despite the benefits, the biotechnological application in …

Leds To Replace Fluorescent Tubes For Growth Of Cultured Algae, Grace Alego, Christopher Bentley, Rebecca Smith, Darian Kelley, Richard Synder

Reports

Fluorescent bulbs are widely used for algal culture stocks and production in aquaculture operations. Metal halide lamps are also used for production tanks with significant electricity demand and heat production. LED technology promises lower operational costs with less energy waste as heat for equivalent light energy production. Re-tooling algal production facilities with new LED fixtures incurs significant expense that must be recaptured in savings over time. The initial cost, added to concerns over the unknown response of algae to LED light sources may both be factors inhibiting incorporation of this new technology. LED replacement tubes are available to retrofit fluorescent …
