This document summarizes a project focused on improving tank hydrodynamics in aquaculture and aquaponics systems through the design of vertical manifolds. It discusses how optimizing flow patterns can maximize a tank's self-cleaning ability and improve water quality. The initial trout tank system at the University of New England Marine Science Center faced challenges from high biomass that overwhelmed the filtration. Prototyping vertical manifolds based on the Cornell dual-drain design aims to create uniform circular flow for better solids collection. Future applications include incorporating the design into a new recirculating system and aquaponics pilot system to further optimize nutrient cycling between fish and plants.

Abstract
Aquaculture will continue to grow as the expected fish demand will increase inevitably with the
rising population. The reliance on aquaculture systems comes with responsibility of owners and
respective stakeholders to assure that the systems are using sustainable and environmentally
friendly mechanisms. This report discusses various ways to create a more sustainable and
environmentally friendly aquaculture system in terms of fishmeal alternatives, built-structure
types, and antibiotics and chemical usage to give recommendations to fish farm owners. The
report also touches on ethical practices in owning an aquaculture system. The most sustainable
3
method was found to be feed using microalgae and insects, structure type of pen and cage, and
phage therapy as an antibiotic treatment replacement.
1.0 Introduction: Background of Aquaculture Systems
1.1 Current Unsustainable Aquaculture Methodology
With the world’s increasing in population, fish and seafood in general has become widely relied
on as a source of protein, and this reliance will continue and grow. In 2030, it is expected that
150 to 160 million tons of fish will be consumed (“Global and regional food”, n.d.). Besides
fishing, aquaculture is a major method in which we obtain fish, and will continue to be to meet
the world demand of fish. Aquaculture is diverse in its methods, but the main idea is to create a
farm in a body of water to efficiently produce copious amounts of seafood like fish (freshwater
and saltwater), and shellfish. Many factors go into an aquaculture system to assure its success,
such as the feed type, the farm location, and the farm structure. Many may assume that
aquaculture would decrease pressure on fisheries because fish are being separately farmed for the
purpose of eating, however this is not the case. Currently “Around 85% of global fish stocks are
over-exploited, depleted, fully exploited or in recovery from exploitation” (Vince, 2012). This is
greatly concerning as it is known that the global population is only increasing, and therefore the
global demand for fish consumption will only increase as well..
There is an intrinsic connection between biodiversity conservation, water and sanitation. With appropriate technologies, wastewater can be treated to produce fit-for-purpose water with recovery of nutrients to enhance biodiversity conservation in terms of flora and fauna. This project highlights a pilot subsurface flow Constructed Wetland unit in order to identify its performance in treating domestic wastewater and in recovering nutrients.
The project won the 1st Prize in National Quarry Life Award in 2012 in Tanzania.

The aquaponics term derives from the words aquaculture and hydroponics, which by definition, has the meaning of aquatics organisms culture and plant breeding techniques without soil, respectively. This activity has how the main feature the sustainability, once the modality looks for the production with low water consumption and high exploitation of waste generated. The present study had as objective to describe the construction of the aquaponics pilot system. This way, based on the literature and acquired experience during the work, a step-by-step method was established for the assembly of the system. To verify the process efficiency, were analyzed the presence of total and thermotolerants coliforms, counting of facultative mesophiles and quantification of micro and macronutrients in leaves and roots of Xanthosoma sagittifolium. There was no presence of total and thermotolerants coliforms in leaves and roots of X. sagittifolium. In the count of facultative mesophiles the roots presented 6x104 CFU/g and the leaves 1.7x102 CFU/g. In the foliar analysis, 1430mg/kg of Fe was observed in the roots. It was concluded that the pilot project was successfully built and testing can be continued with new plants.

Slide 1: Victoria Tycholis
Aquaponics is an agricultural system which combines aquaculture and hydroponics in a symbiotic relationship. The result of this integration is edible fish and fresh produce from a single operation (Palm).
Aquaponics relies on two core ecological relationships. One is between the fish and plants raised. Fish raised in tanks make excretions that enter the system’s re-circulated water. The so-called “waste water” from the fish tank delivers bio-available nutrients directly to the bare roots of the crop plants; this circumvents the soil-root contact normally required to deliver nutrient-laden water. By the absorbing action of crop roots, the plants provide a filtering service to the fish. This allows for clean, habitable water for the fish to continue developing and breeding in.
The second ecological relationship is between bacteria and plants, which enables the first relationship. Bacteria “fix” the nitrogen that plants need by nitrification. The bacteria take the ammonia from fish excrement and convert it into nitrite then nitrate. Two groups of bacteria are required to make the nitrogen in fish excrement available. Nitrosomonas convert the ammonia into nitrite. Nitrobacter then convert the nitrite into nitrate (Nelson). For the farmer, these relationships mean that fertilizer is essentially being produced on-property. The enclosed nature of the entire system means that the farmer doesn’t have to worry about polluting the environment with fertilizer run-off.
The key components of an aquaponics system are as follows: The first component is one or more large fish tanks; the fish that are raised must be able to grow quickly and unencumbered by high population densities, such as tilapia. The second component is buoyant growing beds filled with growing medium such as ...

HYDRODYNAMICS IN AQUACULTURE AND AQUAPONICS

Background
The aquaculture industry is a dynamic field which is growing at a rapid rate. This growth is driven by a combination of static or declining catches from most traditional fisheries, declines in stocks of
many commercially caught fish species, and the increased need for marine protein as a result of global population growth. Consequently, aquaculture engineering is being turned to for solutions that
allow this growth to be possible. Aquaculture engineering requires great knowledge breadth, covering traditional general engineering specialties such as mechanical, environmental, materials
technology, but also solid understandings of biology, chemistry, and ecology. Understanding how these specialties interact and complements each other allows one to engineer solutions that
efficiently utilize resources, such as water, land, feed, broodstock and seed, to their fullest potential. Balancing engineering and biological interactions ensures quality aquaculture systems with hearty
products required for our expanding society. This project focuses on engineering designs that drive aquaculture and aquaponics tank hydrodynamics in order to maximize a tank’s self cleaning
capabilities. Effective self cleaning is desirable because quickly collecting and removing settable solids improves water quality, system function, and overall economy. In the case of aquaponics the
solids are further processed via additional system engineering to provide valuable plant nutrition.
Trout Room Internship Pratt & Whitney Fellowship
Introduction
The University of New England is enthralled in new and groundbreaking
opportunities in sustainability and human food systems. A pivotal place for new
growth and development has been the Marine Science Center (MSC), where
students can be immersed in new hands-on learning initiatives and allowed to
explore their passions. Through collaborations between the Marine Sciences
and Biology departments, one project that was made possible was the
repurposing of a 10,000 gallon pool for the growout of Kamloops variety of
Rainbow Trout (Oncorhynchus mykiss) obtained from Shy Beaver Trout Hatchery
in Hollis, Maine. In the Spring of 2015, I held a UNE CAS internship focused on
managing the Trout project, inheriting a quickly changing system that taught me
the intricacies of managing new and evolving system processes.
Design Lessons Learned
Undersized filtration and high stocking densities lead to high waste production
creating immediate and significant challenges for managing water quality and
operating the system efficiently. Upgrading filtration components is a logical
and simple solution, but expensive. But even the best filtration, is only as
good as the systems ability to concentrate and collect settleable solids.
Hence, identifying improvements and creating prototypes for improving
system hydrodynamics were the immediate steps towards resolving the tank's
self cleaning challenges.
Challenges
The trout were housed in a recirculating system initially designed for holding
sea turtles. As a repurposed system, the trout’s high stocking density
overwhelmed the system’s capabilities and forcing new solutions to be
identified. The system was run as both a recirculating and flow through to
control parameters such as temperature shifts, open-environment
interactions, and water quality. When operated as a closed-looped,
recirculating aquaculture system (RAS) additional challenges arose due to
shifts in dissolved oxygen (D.O), pH, and Ammonia (Nitrate and Nitrite).
Acknowledgments
I would like to give a special thank you to Pratt & Whitney for funding my fellowship in Aquaculture Engineering; as well as The University of New England College of Arts and Science and CAS Internship
office for allowing me to work alongside a group of amazing people; Asahi- America, Inc. for donating parts; and my mentors and advisors Shaun Gill, Jeri Fox, Adam St. Gelais, Timothy Arienti, and Troy
Thibeau for all of their help across two different internships and throughout this fellowship.
New Prospects
Through the generous support of Pratt & Whitney, I was awarded the 2015
Pratt and Whitney Marine Fellowship in Aquaculture Engineering. My
fellowship focused on evaluating and decommissioning the initial trout
system along with doing research to identify and prototype engineered
solutions for improving aquaculture and aquaponics tank hydrodynamics.
This summer’s work entailed reverse engineering and tested vertical
manifolds to increase flow velocities in the Oncorhynchus mykiss holding
tank. The goal is to provide a successful proof of concept that will provide
grounds for future investments in system infrastructure.
Understanding the Cornell Dual-Drain System
Researchers at Cornell University dedicated to creating sustainable
agricultural and food production processes developed a world-renowned
aquaculture and aquaculture engineering design called the Cornell dual-
drain self cleaning system. They determined that creating uniform flow in a
round tank via vertical manifolds allowed them to collect settleable solids at
a centralized point (i.e. a modified center drain). In addition, the
incorporation of a second side drain would be able to skim off the remaining
solids that float to create better water quality and more efficient use of
resources.
Design Challenges
Fully adopting the Cornell design specifications was a
challenge as the MSC pools are made of concrete and
rectangular in shape. Due to limited information
availability on manifold and center drain design the
vertical manifold prototypes were reverse engineered
based upon literature findings and limited
photographs and opted for a modular design to
promote trial and error. The manifolds are
constructed with threaded fittings that can be
interchanged for experimentation and easily swapped
out in the event of part failure. True-Union Balls
valves donated by Ashai-America allowed for fully
customizable water flow and direction adjustments.
Manifold testing is currently underway to determine
proper nozzle orifice size and number for achieving
rotational velocities that promote self cleaning.
Application to Aquaponics
A Balancing Act
When simultaneously growing fish and plants in the same system, finding a balance
between feed additions, nutrient conversion and overall water quality is crucial, each
relying heavily on proper system engineering and hydrodynamics. Below, preliminary
data from the MSC system shows how a properly functioning system maintains at or
near-zero ammonia levels (red) , which is toxic to fish, even as feed levels (light blue)
are increased, causing subsequent and desirable increases in nitrate levels (purple)
for improved plant nutrition.
As part of the sustainable and Edible Campus initiatives at the University of New
England, a student-centered aquaponics system was developed. Aquaponics is the
fusion of two sustainable practices, hydroponics and aquaculture, in which the waste
of one organism is beneficial to another. Hydroponics is a soilless method of growing
plants in soil-alternative media or fully immersed in water. In comparison to
aquaculture which prioritizes fish as end products, aquaponics prioritizes plants
nourished by strategically collected and re-purposed fish waste. Despite different end
products, all three practices rely upon efficient hydrodynamics and system
engineering for concentrating, collecting, and moving waste. In the case of
aquaculture, the waste is simply collected and removed. Aquaponics, on the other
hand, takes the collected waste and through the process of biological filtration
converts the normally toxic fish waste into bioavailable nutrition for plants.

Future Directions
In the future we hope to see this whole room function as a research and
educational centerpiece. There is much to be learned about rearing fish for
open ocean stocking, and the biology and chemistry of such a complex
system. As a living system we hope to teach students how to interchange
components and understand system operation and appreciate design.
Design specifications call for a 140 gpm of
flow through the manifolds. The modular
nature of this design allows all system
components the ability to rotate and
swing in a 360◦ motion, allowing for almost
infinite flow adjustments. Experiments
employing a rubber ball to measure
surface currents are helping to determine
rotational velocities. Furthermore, the
seawater being used unfiltered and
contains particulate solids. Upon shutting
the system down, the shape and
concentration of the solids deposited on
the tank bottom are used are used as a
proxy for assessing hydrodynamic efficacy.
