How
the fish tastes?
No
other liner can describe better about the taste of fish
“Give
a man a fish, he will eat it for a day
teach him how to fish & he will eat through his
life”
·
How
fish can be raised?
The
best part about fish is that we can raise them in small
ponds as well as big ponds kuhl, channel which are
generally found in village but fish can also be raised by
constructing earlier ponds in Agriculture farms or by the
construction of exclusive fish farms.
·
How
knowledge of basic fish farming will help you?
The
basic fish farming may be summed up as character of water,
availability of fish seed of desirable species of fish,
control of fish enemies and marketing of fish produced
from your ponds.
·
What
are the main characteristics of culturable fish?
ü
Should
grow fast easy to breed;
ü
Preferably
herbivorous compatible with other species;
ü
Should
have consumer preference.
· What
required for profitable fish farming?
Getting
profits from fish farming depends on complete
understanding the principles that govern the growth and
survival of fish.
·
Where
from you can have this understanding?
To
provide this understanding 10 days course in fish farming
are been conducted by Fish farmers Development Agency,
Bilaspur & Kangra, syllabus can be obtained free of
cost by writing to any office of the department’s
situated in different parts of the state.
·
How
can you find out whether or not your soil will hold water
for a pond?
In
selecting a site for the pond you should also be sure that
the site will hold water. Some are too porous or will need
special treatment in order to hold water. If possible
before starting to construct the pond, consult Fisheries
expert to check the area and the soil.
·
What
is a good size and shape for a carp pond?
After
selection of the site for the pond with a good water
supply, you can start digging. The size and shape of the
pond should range between 0.1 hectare to 0.8 hectares in
rectangular shape will be a good size pond. In case of
running water unit the size is 30X1.5X1.2m.
·
How
deep should a carp pond be?
The
water should be 2 mtr deep and one end and 1 ½ meter deep
at the shallow end.
·
What
can be done to prevent heavy rains from flooding the pond
and breaking the dam?
If
the pond is built in a place where it collects too much
water in times of heavy rains, a wide ditch should be dug
at one side of the Bank to carry away the extra water,
when it rains hard, the extra water will run through the
side spillway rather than break the sides of the pond.
Kinds
of fishes suitable for farming:
·
Mirror carp/Rohu/Silver carp/ Catla catla/Mirgla
etc for warm district , trout for Coldwater district
·
How
does raising of fish in farm pond benefits your family?
In
one-hectare ponds, one can harvest 5,000 kgs. of fish
proper care, feeding and manuring is timely ensured. It
can provide fish for the family and extra for the market
as cash crop.
·
What
can the water in fishpond are used besides fish farming?
If
there is a good source of water, fishpond can be used as a
reservoir for irrigating Agriculture fields.
Pond
Construction:
·
Are
there any places where a fish pond should not be
constructed?
Another
problem is that floods may wash away the banks. To avoid
this you should not construct a pond in a gully where
heavy floods occur. Large gully would not be good place
for the construction of a pond.
·
Why
should we put fences around our ponds?
The
pond should be fenced to keep out cattle. Cattle will
break down the banks of the fish pond. There should be a
Pacca cattle ramp for the entry and exist of the cattle.
This is very important to prevent the damage of bunds,
which may also cause easy entry of rainwater during heavy
downpour.
·
How
long should carp be stocked in a pond before one starts to
fish them out?
If
you construct good ponds and manage them well. Carp will
be big enough and so you can start fishing them out within
about a period of two years from first stocking and
thereafter every year by the replenishing the stock
simultaneously. The family will have good Nutritious Food
to eat and surplus can be sold for profit.
·
From
where one can get fish seed for fish farms:
Seed
of Indian Major Carps & Mirror carps is available at
State’s fish farms Ghagus (Bilaspur) Alsu (Mandi) Kangra
(Kangra) & Sultanpur (Chamba) during June to August
every year. Where in case of trout availability is during
May to June at State’s trout fish farms Patlikuhl (Kullu)
Barot (Mandi) Nagni (Kullu) Holi (Chamba) & Sangla (Kinnaur).

Care
feeding & Management:
·
How
should water look in a pond for fish?
Water
for growing fish should not be clear and transparent. It
should be greenish in colour. The green colour means that
the water has lots of small plants called Algae, which
provide food for the fish. (Applied only for carp
farming).
·
What
does the colour in fish pond water means?
The
colour of water is indicator whether the pond has enough
fish food in the pond or not. So the colour of the water
is very vital important factor to make a start in the fish
culture.
·
What
can be used to fertilize a fish pond to make the water
greenish?
Ponds
need to be fertilized just as we fertilize out fields and
gardens. Any kind of animal manure makes good fertilizer.
·
How
do you fertilize a pond with cow manure?
Cow
manure should be put in the pond in a burlap sack. The
Nitrogen will be dissolved by the water, and will help the
green algae to grow.
Lab
to pond service:
·
How
much chemical fertilizer should be thrown into a small
pond to fetilize it?
Chemical
fertilizer with lots of Nitrogen is also good. Only a few
handfuls are needed for a small pond.
·
If
the soil is acidic, what must be done to a fish pond?
In
some areas, where soils are acidic, lime must be added.
The lime can be spread on the bottom of the pond, or it
can be thrown into the water.
·
What
causes a green scum on the surface of a fertilize fish
pond?
In
a fertile pond, the water may have a green scum on top.
The fish like to eat the green scum, which consists of
many small plants. It indicates that the pond is ready for
planting fish seed.
·
What
kinds of fishes are the best for stocking in ponds?
Catla,
Rohu, Mirgal, Mirror carp, Silver Carp, grass carp and
trout are the best kinds of fish for stocking in ponds/
raceways. These all kinds can grow fastly in a pond
without competing with each other in consuming food of the
pond.

|
Disease and Causes |
Symptoms |
Reason for
Infection |
Action |
Treatment |
|
Ulcers
Caused by
Pseudomonas and Aeromonas bacteria |
Pinky-white open
wounds, often with a white edge and sometimes
secondarily infected by fungi and other bacteria. |
Very poor water
quality or an excessively high pH level. Minor
scratches can become infected if conditions are poor.
Also commonly affects newly imported Koi and goldfish. |
Test the water for
signs of ammonia and nitrite. Conduct a large water
change to reduce pollution levels. |
Fish lose salts
quickly through open wounds, so add aquarium salt at a
dose of 1-3g/litre. Use an anti-ulcer treatment. If
treatment fails, a vet can prescribe stronger
antibiotics. |
|
Cloudy eye
Caused by poor
water quality, poor diet, eye flukes, corneal damage,
bacterial infection. |
Entire surface or
lens of eye takes on a cloudy, opaque appearance.
There may be a build-up of mucus on the outer surface. |
Most commonly
caused by poor water conditions. A lack of vitamins in
the diet may also cause clouding. On rare occasions
digenetic flukes, such as Diplostomum, can
cause problems. |
Improve water
conditions. Use a good quality food containing added
vitamins. |
Improving water
conditions usually cures cloudy eyes. Eye flukes are
uncommon and can be difficult to accurately diagnose
and treat. |
|
Dropsy
Usually caused by
bacterial infection. Viral infection, nutritional,
metabolic and osmoregulatory problems can also be
responsible. |
Swelling of the
body cavity due to a build-up of fluid. Scales become
raised giving a pinecone-like appearance. One or both
of the eyes may be protruded. |
Usually triggered
by poor water quality, especially the presence of
ammonia and nitrite. Often confined to individual
fish. |
Test water and
improve water conditions immediately. Aquarium salt at
a dose of 1- 3g/litre can help to prevent salt loss. |
Can be difficult to
treat. A broad spectrum anti- bacteria treatment is
the best option in most cases. |
|
White spot
Caused by
Ichthyophthirius multifiliis parasite |
Small white spots,
about the size of a salt grain, on the skin, fins and
gills. |
Stress related.
Usually a consequence of poor or incorrect water
conditions, fluctuating temperature and general poor
husbandry. Sensitive species may develop white spot as
a result of being introduced to a new aquarium. |
Ensure the water is
free of pollution and isolate cause of stress. |
Treat promptly with
an anti-parasite medication. It may be necessary to
raise the water temperature to improve the
effectiveness of the treatment. Wounds left by
parasites may become secondarily infected.
|
|
Bacterial infection
Caused by
Aeromonas and Pseudomonas bacteria |
Reddening of the
skin or fins; ragged fins with signs of infection,
open sores. Common on many newly imported fishes.
Often accompanied by other diseases, including fungi. |
Poor water
conditions, especially the presence of ammonia and
nitrite. Wounds resulting from poor handling,
transport or fighting may become secondarily infected
by these bacteria if conditions are poor. |
Improve water
conditions, and treat promptly. |
Use a proprietary
treatment as soon as possible. Aquarium salt at a dose
of 1- 3g/litre can help prevent salt loss. Severe
infections may require prescription medications from a
vet. |
|
Fungus
Caused by
Saprolegnia and Achlya |
Fluffy growths
affecting wounds on the skin and fins of freshwater
fishes. |
Usually a secondary
infection that invades wounds left by ulcers and
parasites, including whitespot. Rarely a problem in
tanks with good water quality. |
Improve water
conditions and treat promptly. |
Standard anti-
fungal medications, such as methylene blue, are
usually very effective, but may affect filtration and
water quality. When the disease occurs on open wounds,
aquarium salt at a dose of 1-3g/litre can help reduce
salt loss. Cotton-wool disease (Flexibacter)
looks similar but is caused by bacteria and may
require a different treatment. |
|
Finrot
Caused by
Aeromonas, Pseudomonas or Flexibacter
bacteria |
Frayed fins, often
with a pale pinky-white edge and some blood in the fin
tissue. |
The bacteria are
present on most fish. Stress from poor water
conditions usually triggers an infection. Nipped fins
may become secondarily infected if water is polluted.
Some wounds may also be attacked by fungus. |
Improve water
conditions. Isolate nippy fishes. |
Treat promptly with
a finrot or anti-bacteria treatment to prevent the
further spread of the disease. Consider adding salt
(1-3g/litre) to reduce the loss of salt by the fish.
Ensure that water stays free of pollution during
treatment. |
|
Swimbladder
disorder
Caused by bacterial
infection, incorrect diet, trapped gas, physical
deformities. |
Fish have
difficulty swimming to the surface, or to the lower
levels of the tank. Commonly affects egg-shaped fancy
goldfish. |
Sometimes caused by
poor water quality. Genetic problems in
selectively-bred goldfish. |
Improve water
conditions. Feed less dried foods, or pre-soak pellets
and flakes so they don't swell the gut. Feed
Daphnia, which acts as a laxative. |
Change diet and
improve water conditions. Treat with a specialist
anti-bacteria treatment. Fancy goldfish suffering from
physical deformities will not recover. |
|
Lymphocystis
Caused by an
iridovirus |
The virus causes
crusty grey-white lumps to develop on the skin and
fins. These may affect freshwater or marine fishes,
and sometimes take on the colour of the underlying
skin. These lumps are clusters of enlarged cells. |
The disease is
viral, but may be triggered by stress, poor handling
or poor water. Some fish may carry the virus without
showing symptoms. |
The disease rarely
kills, although lesions may become secondarily
infected. Ideally, infected fish should be isolated. |
There is no known
treatment. Some vets recommend the surgical removal of
the lesions. |
