1. Introduction to the biofloc fish farming technology.
Biofloc is a
type of fish farm that uses natural materials to attract the fish to its
environment. Biofloc is a system of using organic materials to create a habitat
for the fish to live in. Fish farms use these materials to help keep their
water clean, fresh, and free of pollutants. Biofloc fish farms do not use any
toxic chemicals or antibiotics to treat the fish. Instead they use natural
methods to keep the water clean and safe.
The first step in building a biofloc fish farm
is to build a tank where the fish will live. The tank should have a minimum
depth of 1 meter (3 feet) to allow enough room for the fish to swim around
freely. Next comes the filtration system. Filtering systems remove impurities
from the water, keeping the water clean and clear. A simple filter would
consist of gravel or sand at the bottom of the tank and a pump to move the
water through the filter. As the water passes through the filter, the
impurities settle out of the water and collect at the bottom of the pool. Once
the water reaches the top of the filter, it flows back down to the tank. The
water then goes back through the pump and returns to the tank. After the water
cycles through the filtering system, it collects in a separate container called
a sump. From here, the water is pumped back to the tank.
Once the tank is built, the next step is to
add the biofloc material. There are two types of biofloc material: activated
carbon and peat moss. Activated carbon is created by heating wood in a kiln
until it becomes charcoal. Charcoal is then ground up into small particles.
Peat moss is a naturally occurring substance that grows deep underground. When
peat moss is dug up, it is dried and compressed into blocks. These blocks are
then broken apart and added to the tank. Both activated carbon and peat bogs
are great options for adding biofloc material.
After adding the biofloc material, the final
step is to introduce the fish. Biofloc fish are raised in groups of 20-30. Each
group is kept together in a single tank. Before introducing the fish, the tank
should be cleaned thoroughly. Cleaning the tank removes any leftover food
debris, bacteria, and parasites that may have been left over from previous
tanks.
There are many different species of fish that
can be used in a biofloc fish tank. Some popular choices are tilapia, goldfish,
koi, guppies, platys, tetras, and rasbora. Tilapia and goldfish are both good
choices for beginners. Goldfish require less space than tilapia and are easier
to care for. Tetra and rasbora are also good choices for beginners. Tetras are
peaceful and calm while rasbora are aggressive and territorial.
Biofloc fish farms are a great way to raise fish
without having to worry about them getting sick or dying. Because the biofloc
material attracts the fish, there is no need to feed them. In fact, feeding the
fish could cause problems. If the fish eat too much, they may become
overweight. Overweight fish cannot breathe properly and may die. Also, if the
fish eat too fast, they may choke themselves.
Biofloc farms are an environmentally friendly
method of raising fish. Unlike traditional fish farms, biofloc farms do not use
harmful pesticides or antibiotics to control disease. Instead, biofloc farms
use natural methods to keep their fish healthy. Additionally, biofloc farms
recycle water instead of wasting it.
2. How does biofloc fish farming work?
1. What is Biofloc?
Biofloc technology uses the natural settling
properties of microorganisms (bacteria) to collect suspended solids (including
heavy metals, pathogens, debris, etc.) from water bodies and concentrate them.
The concentrated sludge is then collected using nets and dumped into specially
designed ponds where it settles out naturally without any human intervention.
The end product of this process is clean clear water.
2. How Does Biofloc Work?
The bacteria in the pond accumulate on the
surface area of the floc as they attach themselves to the particles and begin
to secrete enzymes that break down the pollutants and enable their removal. As
the floc continues to grow, it becomes heavier than the water and sinks to the
bottom of the pond. Once it reaches the bottom, the floc enters a phase called
“clarification”, where its size increases, making it lighter than the
surrounding liquid.
3. Where Can I Use It?
This technology could potentially be useful in
many different applications since it removes many types of contaminants
including metals, plastics, oils, pesticides, and even pharmaceutical drugs.
However, we currently only have two companies offering commercial-scale systems
that use this method for water treatment: AquaBounty and Aquasana. Both of
these companies offer the system primarily for the marine industry, and both
claim to be able to produce enough food to sustain four million salmon per
year. In addition to that, they claim to be able to treat wastewater to remove
80% of all regulated pharmaceuticals.
4. Why Do We Need Clean Water?
Clean water is necessary for people to live
and thrive. To have clean water, it is important to ensure that water quality
stays at optimal levels. However, pollution levels often make it difficult for
us to enjoy our drinking water, especially if there is contamination from
agricultural runoff or industrial waste. If we do not take action to reduce
those problems, then it means that everyone in the world will suffer from
disease. This includes humans who consume contaminated water.
1. Fish
Farming is an effective method of rearing aquatic animals for commercial
purposes, using recirculated water systems.
2. Biofloc technology uses an advanced
biological system called biofloc bacteria to remove ammonia and nitrite from
wastewater.
3. Biofloc technology takes advantage of the
natural tendency of microorganisms (bacteria) to reproduce and grow under
certain conditions.
4. Biofloc bacteria requires oxygen, carbon
dioxide, sunlight, protein-rich food and some metals.
5. When wastewater passes through the
flocculation tanks, it receives a layer of slimy bacterial mass.
6. As the tank becomes full, the surface area
of these bacteria increases, and they form a protective layer over the top of
the liquid.
7. The thin film of slime formed will begin to
act like a sponge, soaking up any impurities in the water.
8. In this way, wastewater is cleaned before
being returned to nature.
9. Ammonia and nitrites are removed from the
water using biodegradable polymers, which attach themselves to the bacteria and
hold them together.
10. Once the wastewater is clean, it is then
pumped back into the river or lake where it was originally taken from.
11. A single biofloc unit can treat up to
10,000 gallons of water per day.
12. Most importantly, biofloc technology does
not use chemicals which pollute the environment.
13. Biofloc units are cost-effective and
environmentally friendly.
14. Biofloc technology is best suited for
small communities or households which have trouble disposing their wastes
properly.
15. Biofloc
fish farming is helping to reshape aquaculture by reducing the amount of waste
that is produced.
16. Biofloc
fish farming is also helping to improve the quality of fish stocks.
