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 …

Modeling Energy Flows In Floating In-Pond Raceways Utilizing Solar Power Back-Up, Bo Smith

Theses and Dissertations--Biosystems and Agricultural Engineering

The In-pond Raceway (IPR) is a novel option for production aquaculture, depending on water moving devices to provide constant flow. Device failure may result in catastrophic fish loss, requiring power backup systems to mitigate risk in case of power outages. Because these systems must be dependable and many suitable locations are remote, off-grid solar photovoltaic (PV) systems with battery storage have been considered since they eliminate need for utility power. Such systems can be hard to size and expensive. This study modeled system requirements using an energy balance to determine whether systems could withstand varying loads based on climatological conditions. …

Using Zebrafish (Danio Rerio) To Evaluate The Use Of Food Waste Based Feed In Sustainable Small-Scale Aquaculture, Caitlin May

Electronic Theses and Dissertations

Food waste is rich in nutrients and a valuable resource, but currently its primary method of disposal in the United States (US) is unsustainable. In 2018 the US Environmental Protection Agency (EPA) estimated that the commercial, institutional, and residential sectors of the US economy wasted 63 million metric tons of food, most of which was sent to landfills. Instead, food waste could be recycled and used to supplement or replace commercial feed in aquaculture to sustainably stimulate production of fish. Zebrafish (Danio rerio) are a well characterized animal model closely related to other fish species that are important …

Sustainable Production Of Feed For Recirculating Aquaculture Using Black Solider Flies And Microalgae, Patrick Erbland

Electronic Theses and Dissertations

The demand for high-quality, nutritious food continues to increase as human populations grow. As wild fisheries are depleted, aquaculture production is growing to meet the demand for seafood. Sustainable alternatives to wild caught fish meal are increasingly valued for aquaculture feed production. Microalgae and insect larvae are both valuable sources of fatty acids in aquaculture feed. Black soldier fly larvae, Hermetia illucens (L.) are used to convert organic waste streams into insect-based animal feeds. We tested their ability to retain alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) from feeding substrates, which has important implications for their use …

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 …

The Community Influence Of Sponge And Coral Aquaculture In Zanzibar, Hanna Gaertner, Asma Ahmada Hamad, J. Richard Walz

DU Undergraduate Research Journal Archive

Aquaculture has been presented as a means of income for coastal communities, particularly in the context of climate change and resource exploitation. The NGO Marine Cultures in Jambiani, Zanzibar has established a sponge cultivation program for women in response to declining feasibility of seaweed farming from warming ocean temperatures. In addition, the organization strives to restore a severely damaged reef while providing employment for coral farmers and tour boat operators. This study analyzed the influence of aquaculture on community stakeholders, primarily with respect to sponge cultivation and secondarily in regard to coral farms. Using Marine Cultures as a case study, …

Growth Of Juvenile Red Abalone (Haliotis Rufescens) Fed Different Seaweed-Based Diets, Quinn C. Wulffson

Cal Poly Humboldt theses and projects

The rise of abalone aquaculture has mitigated most of the global demand placed on wild stocks of abalone; however, the current production of abalone relies heavily on naturally harvested kelp. The continued reliance on wild kelp as a feed source further contributes to the disappearance of kelp forests throughout coastal ecosystems. This study aims to better understand how juvenile red abalone Haliotis rufescens grow and utilize nutrients from three diets: a control diet of naturally harvested bull kelp Nereocystis luetkeana, a formulated commercial diet (ABKelp^®), and Pacific dulse Palmaria mollis produced using Integrated Multi-Trophic Aquaculture (IMTA). Juvenile …

Assessment Of Off-Bottom Oyster (Crassostrea Virginica) Aquaculture Techniques On Biofouling In The Northern Gulf Of Mexico, Ellis Chapman

LSU Master's Theses

Although off-bottom oyster aquaculture is a rising industry in the northern Gulf of Mexico, it is susceptible to biofouling, the accumulation of organisms on industry surfaces. Biofouling creates problems for commercial growers by increasing the costs of labor associated with biofouling management. The most used off-bottom production techniques involve aerial exposure. OysterGro™ 6-slot off-bottom oyster cages were used in this project to test aerial exposure frequency, antifouling coatings and bag position on mortality, growth rates, shell ratios and condition indices on four sites in the northern Gulf of Mexico. Aerial exposure of floating cages was performed in increments of once …

Incidence And Prevalence Of Francisella Noatunensis Subsp. Orientalis (Fno) Pathogenic Infections In Feral Hawaiian Tilapia, Daquille Peppers

Biology Theses

Aquaculture has become a major food source for many countries and continues to grow each year. However, many of the fishes that are farmed are susceptible to pathogenic infections such as Francisellosis, a bacterial infection that contributes to disease and high mortality rate in many populations of farmed and wild fish around the world. In 1994, feral and farmed populations of tilapia (e.g. Oreochromis mossambicus) on Oahu, Hawaii were found to be infected with a novel Francisellosis strain, Francisella noatunensis subsp. orientalis (Fno). To prevent the spread of this pathogen, the Hawaii Department of Aquaculture (HDOA) initiated …

A Fishy Problem: Effects Of Atlantic Salmon Farming In The Pacific Ocean, Madeleine A. Griffith

Student Theses 2015-Present

In this report, I explore the historical, climatological, economic, and ethical issues created by the contemporary industrial salmon farming practices off Pacific coast of the United States and Canada. Chapter 1 utilizes a variety of sources from Stephen Hume’s A Stain upon the Sea to Miller’s Living in the Environment, to examine the integral part salmon plays in both freshwater and marine ecosystems, the ecosystem services salmon contribute in wild and farmed settings, and the trends in salmon consumption around the world. Chapter 2 examines the historically relevant role salmon held among indigenous societies and how that role has changed …
