The document discusses the benefits of using solar energy in fisheries. Some key points: - Solar energy has minimal negative environmental impacts compared to other energy sources as it produces no pollution, greenhouse gases, or noise. - Solar energy requires only an initial investment and has no recurring energy bills, unlike other sources. It is also accessible in remote fisheries locations. - The peak hours of solar energy production from 11am-4pm align well with times when fisheries labor is most active. - Using solar avoids energy losses from long distance transmission and makes the utility less complex than other sources. - A designed solar-powered aerator for fisheries uses inexpensive local materials and minimal electricity to

Introduction
The solar energy is a source of energy one can completely rely
upon considering all its pros and cons it is clear to every
individual that it comes with minimal or almost zero negative
effects as compared to any other source of energy. It do not
contribute towards global warming , doesn’t contain any form of
pollutant within itself and has no greenhouse gases.since it
produce no sound in operation of the solar energy it is suitable
for operation even in all domestic ponds and any water body
nearby residence. All the other form of energy that we might
consider as a source of energy for fisheries farm and enterprise
comes with a huge amount of capital investment, whereas solar
energy implantation in any sector only needs the initial
investment in setting up of the infrastructure which is again a
one time or life time investment and does not include repeated
bill payments.whereas “another factor in the increasing
affordability of solar panels is the availability of federal,
state and local tax break”
As per as the fisheries sector is concerned most of
the firms are remotely located and has to suffer
resource scarcity,mainly energy supply which is
again one of the most crucial part of any fisheries
farm manager. Were as the solar energy is
excess-able in all parts with no exception of
remodity.
The peak time of solar energy is between 11:00-16:00 hrs which
again is an asset to fisheries as most of the labour operational
time is included in his frame.
We are also familiar with the energy losses
during long distance transmission of energy from
the source of origin and point of installation
whereas while using solar energy in fisheries this
losses of energy will not happen and save a huge
time and resource which otherwise might get
used in steeping up of the lost energy in other form of
energy,thus making the utility less sophisticated one.

Improved grid security is one more advantage of this energy
resource which contributes towards reliability as overloading
will never lead to grid blackouts or any form of human disaster
or naturally caused disaster is not likely to harm the plant ant
any cost.
Therefore while we talk of the revolutionized Fisheries
sector, implantation of solar energy is one of the key
consideration needs to be assessed.
Why we need solar energy in Fisheries
Utilising Solar Wind Energy in Fisheries Sector Climate
Change is perceived as a major threat primarily to food
production through Agriculture, Fisheries and Animal
Husbandry. Climate Change is the consequence of Global
Warming which in turn is due to increase in greenhouse
gases (GHGs). Carbon Dioxide is a GHG that emanates from
burning fossil fuels such as coal, oil and natural gas for
generating energy/ power/ electricity. In Fisheries &
Aquaculture HSD oil is used as fuel in fishing vessels and in
gen-sets that ensure backup-power for post-harvest fish
processing, cold chain maintenance, etc. Further, electricity
from thermal power plants is essential for most of the
semi-intensive, intensive and modern technology-driven
aquaculture systems. India is the second largest fish
producing country in the world with an annual production of
about 12.60 million metric tonnes and it is aimed to increase
it to 15.00 million metric tonnes. The United Nations
Climate Action Summit recognises that the pace of climate
action must be rapidly accelerated and boosted. Despite
global carbon dioxide emissions rising, India's ranking in the
Climate Change Performance Index (CCPI) 2019 has
improved to 11th position, most notably in its performance in
the renewable energy category, and comparatively low levels
of per capita GHG emissions. India has set for itself a
relatively ambitious mitigation target for 2030. As part of
India’s Climate Change mitigation strategy, the Dept. of
Fisheries, Ministry of FAH&D, Govt. of India, under the
Scheme “Blue Revolution: Integrated Development and

Management of Fisheries” provides financial assistance for
“Promoting Non-Conventional Energy (NCE) Source for
Environment Friendly Fishing Practices” such as use of solar
energy or other NCE sources for lighting, refrigeration on
board the fishing vessels, and other activities.
Design
Design The design concept was to invent a solar energy aerator
that was made from inexpensive materials bought locally. In
addition, the aerator was to consume minimal electricity energy
so that a highwatt solar cell with higher cost was not needed.
Designing buoys of the aerator, PVC with a diameter of 4 inches
was connected to one another in a square shape. Each side was
with 100 centimeters long. Solvent-welding cement was applied
afterwards to prevent water from leaking in. The blades on the
top were covered by synthetic fabrics net and they were rotated
by the water pumped by the 2 sets of the 12- Volt-25-Watt DC
water pump. The pumps connected to both ends of the 2-inch
diameter PVC pipes. The middle section of the pipes was drilled
into many holes. These holes allowed water to unleash in line,
and then fell into the blades paddled into water spray or small
water drop. This process enabled oxygen to dissolve better in
water. On top of the aerator, a 12- Volt-80-Watt solar cell panel
was installed to generate electricity for the 12-Volt, 40-Ah
battery as well as to supply electricity to the 2 water pumps. As
seen in the aerator came with a solar switch control system
which was pre-set for automatic shutdown. Solar energy
aerator drawing design. The block diagram which was an
operations part of the solar energy aerator. The core functions
fell into 3 parts as follows;
1. Electricity generator set and battery backup which comprised
a 12 V 80 W solar panel, a 12 V 40 Ah battery charger, and a 12
V 40 Ah battery to store an electric charge produced by the solar
cell panel and then distribute the electricity to 2 sets the DC
water pumper.
2. Control unit of the solar energy aerator which employed
light-operated switch and timer set to stimulate the operations of
the solar energy aerator when there was sunlight as well as

control the work duration of the aerator. When the timer is due,
the aerator would automatically stop.
3. 2 sets of 12 V 25 W DC water pumper were used for pumping
up water on the blades and then the water was paddled into
water spray in order to increase the oxygen level in the
water.
The expected Rise in DO with respect to time:
Conclusion:
This solar energy driven oxygen pump is expected to produce
required amount of oxygen within the system and with zero
harmful impact on environment.
This will facilitate in renewable source of energy for
aquaculture and thus contributes towards revolutionizing the
fisheries sector with solar energy.
