Nutrients are substance which Nourish the body, promote growth, maintain and repair the body.
Nutrients can be divided into macro and micro nutrients which both are vital for good health.
Macronutrients such as Proteins, lipids, ash and carbohydrate are present in fishes.
Micronutrient such as Vitamins and minerals are essential dietary elements that are essential in very small quantities that mean they must be supplied from outside to body.
Fish as a food has been playing key role in providing the nutrient to many animals as well as humans.
Fish provide essential nutrients especially protein and fat with high biological value so it is often referred as ‘rich food for poor people’.
Protein and fats are the major nutrients of fish which determine the nutritional value of fish.
Fish is a food with excellent nutritive value, which provides high quality protein and a large variety of vitamins and minerals i.e. vitamin A & D, magnesium and phosphorus.
The micro and macro nutrients present in fish makes it better from other animal protein sources. Fish makes a vital contribution to the survival and health of a significant portion of the world's population.
Fish is especially important in the developing world.
In some of Asia's poorest countries (Bangladesh, Cambodia) people derive as much as 75% of their daily protein from fish. In West Africa fish accounts for 30% of animal protein intake.
Fish play an energetic role in terms of nutritional, economic, cultural and recreational activities.
Principal components of Fish
1. Water: Depending upon fish type 86-82% of water is available in fish muscles.
2. Protein
3. Lipid: Fish have a particular role as a source of the long-chainomega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are major building stones of our neural system. These are important for optimal brain and neurodevelopment in children. Alternative sources of omega-3 fatty acids are found in many vegetable oils, but this is in the form of alpha-linolenic acid (ALA), which needs to be converted into DHA. However, in our bodies the conversion from ALA into EPA and DHA is in most cases inefficient, making it difficult to rely only on vegetable oil during the most critical periods of our lives: namely, during pregnancy and the first two years of life (the 1000 day window).
4. Carbohydrates: Fish is an almost Zero- carbohydrate food, good for diabetes and other such patients.
5. Vitamins and minerals
Protein is essential biopolymer that is obtained from both animal and plants sources and these are commonly recognized as a abundant sources of nutrients needed for body growth and development.
Among a wide range of protein sources, fishes play an energetic role in terms of nutritional, economical, cultural, and recreational benefits in the human society; because these are considered to be the richest protein sources.
In developing countries, more than 60 million people rely on fishes and their by-products for income.
The presentation on disease management in aquaculture is prepared for academic purpose. Farmers and entrepreneurs make sure that the proposed drug is permissible in their country. Make sure that you contact experts before you implement them.
A Minimal Water Exchange Aquaculture System, also known as a Recirculating Aquaculture System (RAS), is a modern and sustainable approach to fish farming that minimizes water usage by continuously recycling and treating the water within a closed system. In this system, water is reused and treated to maintain optimal water quality for fish while reducing the environmental impact associated with traditional aquaculture methods.
The key components of a minimal water exchange aquaculture system include:
1. Fish Tanks: These are the primary units where fish are raised. The tanks are designed to provide suitable conditions for fish growth, such as appropriate water depth, temperature, and oxygen levels.
2. Filtration System: RAS incorporates various filtration components to remove solid waste, excess nutrients, and harmful substances from the water. Mechanical filters remove large particles, while biological filters foster beneficial bacteria that convert toxic ammonia into less harmful substances.
3. Water Treatment: Water treatment technologies, such as UV sterilization or ozonation, are used to control pathogens and maintain water quality within acceptable parameters. These methods help to ensure a healthy environment for the fish.
4. Oxygenation: Adequate oxygen levels are critical for fish health. RAS employs techniques such as aerators, oxygen injectors, or oxygen cones to maintain dissolved oxygen levels throughout the system.
5. Monitoring and Control: RAS relies on advanced monitoring and control systems to continuously measure and regulate parameters such as temperature, pH, oxygen levels, and water flow. This ensures optimal conditions for fish growth and allows for timely adjustments if any deviations occur.
The benefits of a Minimal Water Exchange Aquaculture System (RAS) include:
1. Water Conservation: RAS significantly reduces water consumption by recycling and reusing water within the system. It helps conserve this valuable resource and minimizes the environmental impact associated with traditional aquaculture, which often requires large amounts of freshwater usage.
2. Improved Water Quality: The water in a RAS undergoes thorough filtration and treatment, resulting in high-quality water conditions for the fish. By removing waste and controlling water parameters, RAS helps minimize the risk of disease outbreaks and promotes optimal fish health.
3. Reduced Environmental Impact: The closed-loop nature of RAS prevents the release of excess nutrients and waste into the surrounding environment, minimizing the impact on natural ecosystems and reducing the risk of pollution.
4. Increased Production Density: RAS allows for higher stocking densities compared to traditional aquaculture systems. The controlled environment and efficient waste management of RAS enable farmers to maximize production within a smaller footprint.
5. Disease Control: The controlled and isolated environment of RAS helps minimize the risk of disease transmission

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..

Study of Automated and Controlled Aquaponics System An Innovative and Integra...ijtsrd
At the moment, an attempt has been made to adapt, adapt and automate the Aquaponics System technology for the benefit of farmers and to tackle key issues such as food safety and water scarcity. Aquaponics is a combination of aquaculture, which is growing fish and other aquatic animals, and hydroponics which is growing plants without soil. Aquaponics uses these two in a symbiotic combination in which plants are fed the aquatic animal's discharge or waste. In return, the vegetables clean the water that goes back to the fish. Along with the fish and their waste, microbes play an important role to the nutrition of the plants. These beneficial bacteria gather in the spaces between the roots of the plant and converts the fish waste and the solids into substances the plants can use to grow. Aquaponics considered a sustainable production system. It presents a series of beneficial features for the environment such as land conservation, efficient use of water and nutrients, organic fertilization, produce the highest yield on a field, no floor is required, environmental benefits etc. This study describes the overall design and working, list of the component required, cost involved in the setup, maintenance, and operation, advantages and disadvantages of the system. A automatic prototype has also proposed to created a to test the system sustainability.

4. Background with Justification
The human population worldwide currently
exceeds 7 billion, and it is projected to reach
8.5 billion by 2030, and 9.7 billion by 2050
(UN, 2016).
Fish production increased both nationally as
well as globally. Bangladesh is now in 3rd
position among the fish producing countries
in the world after China and India
(FAO, 2018);
Production of safe food for huge population
has become the burning question at the
present era;
Bangladesh is a small but highly disaster
prone country with huge population
Pond based aquaculture is being intensified
but flood and cyclones sweep away the crops
and farmers incurred huge loss in every year.

5. Background with Justification (Contd..)
On the other hand, massive croplands are being
converted to other uses every day that is also
creating pressure on natural resources;
To keep pace with the growing food demand,
farmers using various chemicals to boost up
cereal production that creates human health
hazards as well as environmental problems around
the world;
For taking these chemically enriched foods,
people are suffering from various harmful
diseases;
These activities have adverse impacts on
surrounding aquatic ecosystems- such as loss of
biodiversity, habitat destruction and hampered
breeding etc;
6. Background with Justification (Contd..)
Moreover, the production cost of fish and
vegetables getting higher and higher
everyday;
In this situation we need such a climate
smart and eco-friendly and sustainable
technology for food production which can
handle current problems efficiently;
Aquaponics is such type of technology which
can produce relatively safe food (fish and
vegetables) and keep the environment
hazard-free
It is an environmental friendly, climate-
smart and sustainable food production
system which can able to handle water
scarcity, soil degradation, climate change and
environmental pollution through producing
safe food for ever increasing world
population (Salam et al., 2014).

Background
Strawberry (Fragaria sp.) is a sodium-free, fat-free,
cholesterol-free and low-caloric food. These can able to
protect heart, increase HDL (good) cholesterol, lowering blood
pressure, and guard against cancer;
Many people tried to cultivate strawberries in aquaponics
without success because of failing to monitor the water quality
properly. While the plants need nitrates to survive, the high levels
of ammonia that can quickly kill them off;
To ensure a good growth rate of strawberry plants demanding

Suitability of strawberry production in media based aquaponic system will be
known;
Taste of aquaponically produced strawberry will be known; and
Pathogenic bacteria will be identified if any; and
Cost-benefit ratio will be measured.
31. Background
Aquaponics is a novel alternative method of fish and crop
production system by combining aquaculture and hydroponics;
The principle of aquaponic system is fish excrete contains
potentially toxic nitrogen compounds into nitrite and then nitrate
by nitrifying bacteria which provided in the system.
There also need to create a balance of the macro- and micro-
nutrient amount that fish can release in the water;
It is clear that the supplied feed and stocking density is directly
related to maintain the metabolites flow into the aquaponic
system; and
Thus, an experiment will be conducted to compare the effect of
stocking density on growth performance of tilapia (Oreochromis
niloticus) with bush bean in a recirculating aquaponic system.

36. Experiment 04: Effect of different media on Production
performances of bush bean in aquaponic system
Background
A media bed in an aquaponic system that utilizes media such
as expanded clay, bricklets, gravels etc. as a foundation for root
growth. Water is pumped into a media filled grow bed and then
allowed to flow back to the fish tank.
Most grow beds are composed of heavy substrate such as clay
balls, gravels, sand, perlite, etc. These serve as support systems
for the plants and as bioremediation medias (Rakocy and
Hargreaves, 1993).
Thus it is important to find out the suitability of other media
types to support plant growth.
Therefore, an experiment will conduct to compare the
production performances of vegetables on different media based
in a recirculating aquaponic system.
37. Experiment 04 (Contd……)
Objectives:
To assess the effect of different substrates on the vegetable growth
and water filtration capacity
To measure the nutrient uptake rate of different media
To evaluate the cost-benefit ratio of different media based
aquaponic system.
