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

Scaup Depredation On Arkansas Baitfish And Sportfish Aquaculture, Stephen A. Clements, Brian S. Dorr, J. Brian Davis, Luke A. Roy, Carole R. Engle, Katie C. Hanson-Dorr, Anita M. Kelly
USDA Wildlife Services: Staff Publications
Lesser scaup (Aythya affinis) and greater scaup (A. marila), hereafter scaup, consume a variety of aquatic invertebrates, plants, and occasionally small fish. Scaup have foraged on commercial aquaculture farms in the southern United States for decades. However, the types, abundance, and rate of fish exploitation by scaup on baitfish and sportfish farms are not well documented. Thus, information is needed to understand how fish and other foods influence scaup use of aquatic resources, and any potential economic effects of depredation of fish. From November–March in winters 2016–2017 and 2017–2018, we conducted 1,458 pond surveys to estimate …

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 …

Distribution And Abundance Of Scaup Using Baitfish And Sportfish Farms In Eastern Arkansas, Stephen A. Clements, Brian S. Dorr, Brian Davis, Luke A. Roy, Carole R. Engle, Katie C. Hanson-Dorr, Anita M. Kelly
USDA Wildlife Services: Staff Publications
Arkansas' bait- and sportfish facilities are commonly used by various piscivorous bird species, including lesser scaup (Aythya affinis) and greater scaup (A. marila) that consume substantial quantities of fish. To mediate this predation, farmers implement extensive bird harassment programs that create additional costs to fish loss, thus research investigating the distribution and abundance of scaup is needed to help farmers allocate their bird harassment efforts more efficiently. In winters 2016–2017 and 2017–2018 we conducted 1,368 pond surveys to investigate pond use by scaup on farms during birds' regular wintering period (i.e., November–March). We used intrinsic and …

Food Habits Of Wintering Double-Crested Cormorants In The Mississippi Delta, Terrel W. Christie, Brian S. Dorr, J. Brian Davis, Luke A. Roy, Carole R. Engle, Katie Hanson-Dorr, Anita M. Kelly
USDA Wildlife Services: Staff Publications
Given its ubiquity, it is not surprising that agriculture, including fin fish aquaculture, contributes to food webs worldwide and is used by numerous wildlife for foraging and meeting other needs. Double-crested Cormorants (Phalacrocorax auritus) impact United States commercial aquaculture and are considered the primary avian predator in catfish (Ictalurus spp.) aquaculture facilities in the Mississippi Delta. Recent changes in aquaculture practices, regulatory policies, and decreased overall hectares in production prompted this study that assessed cormorant consumption of catfish in relation to their night roosts through surveys and diet analysis. Cormorants were collected from night roosts from October …

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