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 …

Novel Pilot Development Of A Closed-Loop Sustainable System Between Biogas Renewable Energy, Distilling, And Aquaculture By Vermiculture Of Stillage Wastes, Samuel C. Kessler

The Cardinal Edge

This study provides a mixed-methods approach in analyzing a potential closed-loop system between renewable biogas production from anaerobic digestion, vermiculture production, aquaculture production, and organic wastes with a particular focus on stillage wastes. Such system may hold significant promise for significantly reducing organic carbon and methane emissions from its components, and should be assessed for such. The 2021 IPCC report essentially identified methane reduction as the single fastest way to slow global warming (IPCC, 2021), making the study and implementation of methane-reducing systems and supportive policy for them critical. Knowledge gaps to implementing this system were qualitatively identified as disconnect …

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 …

Estimating Waterbird Abundance On Catfish Aquaculture Ponds Using An Unmanned Aerial System, Paul C. Burr, Sathishkumar Samiappan, Lee A. Hathcock, Robert J. Moorhead, Brian S. Dorr

Human–Wildlife Interactions

In this study, we examined the use of an unmanned aerial system (UAS) to monitor fish-eating birds on catfish (Ictalurus spp.) aquaculture facilities in Mississippi, USA. We tested 2 automated computer algorithms to identify bird species using mosaicked imagery taken from a UAS platform. One algorithm identified birds based on color alone (color segmentation), and the other algorithm used shape recognition (template matching), and the results of each algorithm were compared directly to manual counts of the same imagery. We captured digital imagery of great egrets (Ardea alba), great blue herons (A. herodias), …

Effects Of Nonaerated Circulation Water Velocity On Nutrient Release From Aquaculture Pond Sediments, Xiangju Cheng, Dantong Zhu, Xixi Wang, Deguang Yu, Jun Xie

Civil & Environmental Engineering Faculty Publications

Sustaining good water quality in aquaculture ponds is vital. Without an aerator, the dissolved oxygen in ponds comes primarily from mass transfer at the water-ambient atmosphere interface. As sediment can seriously affect water quality, this study used indoor experiments to examine the nutrient (nitrogen and phosphorus) release mechanisms and fluxes from sediment in aquaculture ponds with moving water but no aeration. The results showed that the ammonia nitrogen (NH₃-N) concentration in the overlying water was inversely proportional to flow velocity and that a higher flow velocity tended to result in a lower concentration in the overlying water, a …

An Evaluation Of Nitrogen Supplementation And Processed Soy Fractions On The Performance Of Cultured Fishes, Brandon M. White

Electronic Theses and Dissertations

World population growth has resulted in an increased demand for a sustainable food supply. This rapid growth coupled with an increased per capita consumption of seafood, has resulted in many of the world’s marine fisheries being over-exploited in an effort to meet the global demand for seafood. Aquaculture has attempted to fill the supply and demand gap created by the dwindling supply of fish in the world’s oceans. Fishmeal (FM) has traditionally been the primary protein ingredient in aquafeeds fed to farm-raised fish, however its unstable supply and increasing price have driven researchers to identify alternative protein sources. Soybean meal …

Development Of An Automated Detection System For Nitrite In Aquatic Environments, Tim Schierenbeck

Theses and Dissertations

The main objective of the project is to develop an automated nitrite sensor for use in aquatic environments, and more specifically for use in recirculating aquaculture systems (RAS), where monitoring can help sustain a controlled environment, protect against nitrite intoxication, and promote fish health. Detecting nitrite manually with semi-quantitative colorimetric test kits, although inexpensive and simple, is prone to inter-user variability and poor sensitivity. An automated nitrite sensor has potential to provide higher resolution measurements at both concentration and time scales and can serve as a research tool for the study of filtration systems essential in maintaining a healthy RAS …

Effects Of Commercial Clam Aquaculture On Biogeochemical Cycling In Shallow Coastal Ecosystems, Annie E. Murphy, Iris C. Anderson, Mark W. Luckenbach

Presentations

The bivalve aquaculture industry is expanding worldwide; sustainability requires improved understanding of its interactions with the environment. As suspension feeders, bivalves, such as clams, reduce primary production through feeding, and thus dampen eutrophication. Additionally, enhanced rates of denitrification, the microbial removal of reactive nitrogen, have been reported in bivalve sediments due to increased organic matter supply through biodeposition; another potential, yet indirect, control on eutrophication. Simultaneously, bivalves can influence local ‘bottom-up’ effects on production by enhancing nutrient regeneration through excretion and microbial mineralization of biodeposits. At clam aquaculture sediments, respiration and nutrient regeneration rates were significantly higher compared to uncultivated …

Magnitude Of The Freshwater Turtle Exports From The Us: Long Term Trends And Early Effects Of Newly Implemented Harvest Management Regimes., Ivana Mali, Michael W. Vandewege, Scott K. Davis, Michael R.J. Forstner

College of Agriculture & Life Sciences Publications and Scholarship

Unregulated commercial harvest remains a major threat for turtles across the globe. Due to continuing demand from Asian markets, a significant number of turtles are exported from the United States of America (US). Beginning in 2007, several southeastern states in the US implemented restrictions on the commercial harvest of turtles, in order to address the unsustainable take. We have summarized freshwater turtle exports from the US between 2002 and 2012 and demonstrated that the magnitude of turtle exports from the US remained high although the exports decreased throughout the decade. Louisiana and California were the major exporters. The majority of …

Building Integrated Aquaculture, Erik A. Woodin

Masters Theses 1911 - February 2014

Exploratory research into a fresh concept, building integrated aquaculture, has found new information on the topic. Motives indicating building integrated aquaculture is important for sustainable development were identified. A review of the literature found relatively little in the way of experiments, aquaculture operations, and case studies which documented or demonstrated a deep understanding of the interactions between building and aquaculture systems. A simple experiment was conducted observing thermal energy and moisture interactions in simulated aquaculture facilities, some with tank covers and insulation. Two different retrofit programs were developed in a case study of building integrated aquaculture for an existing structure …

Evaluation Of Aerial Cluster Sampling Of Double-Crested Cormorants On Aquaculture Ponds In Mississippi, Brian S. Dorr, Loren W. Burger Jr., Scott C. Barras

USDA Wildlife Services: Staff Publications

Concern over increasing numbers of double-crested cormorants (Phalacrocorax auritus) and their impacts on channel catfish (Ictalurus punctatus) aquaculture has resulted in increased need for quantitative information to develop and evaluate depredation management efforts. We evaluated aerial surveys in a stratified cluster sampling (SCS) design to estimate and monitor abundance of cormorants on catfish aquaculture ponds in the Yazoo River Basin of Mississippi, USA (hereafter Yazoo Basin). Twice monthly abundance estimates and coefficient of variation during winter averaged 8,128 (n = 29, SE = 1,233) and 33% (n = 29, SE = 0.02), respectively. Counts of cormorants …
