3. INTRODUCTION
Cold water fishes occupy an important place among the
freshwater fishes.
The cold water fisheries is the branch of fisheries where
the fisheries activity is conducted in the waters that remain
in the temperature range between 5-25°C throughout the
year.
The water temperature under cold water fisheries should
not be more than 25°C even in summer.
The gills of cold water fish are greatly reduced and the
gill opening are smaller in size for adaptation to cold
temperatures.
The himalayan region of India is suite for cold water
fisheries.
Kashmir, himachal pradesh, uttaranchal, kerela etc. states
are in practice with cold water fisheries.

4. In India 258 species (Indigenous + exotic) of coldwater
fishes belonging to 21 family and 76 genera are available.
Government of India established National Research
Centre on Cold Water Fisheries (NRCCWF)
24 September in 1987 (Bhimtal, Uttrakhand)
 Cold water fishes are characterized by:-
• Streamlined body
• Mouth modified for sucking or burrowing
• Narrow gill openings

5. SPECIES OF COLD WATER FISHERIES
 Indian species:-
• Mahseer – Tor putotora and Tor tor
• Snow trout – Schizothorax spp. (Schizothorax
richarsonii)
• Labeo – L. dera, L. dyocheilus, L. rohita
• Barilius – B. bola, B. bendelisis
• Garra – G. lamta
 Exotic species:-
• Trout ( Salmo) – S. trutta, S. gairdneri, S. irideus
• Mirror carp ( Cyprinus) – C. carpio communis, C.
carpio specularis, C. carpio nudus
• Golden carp ( Carassius) – Carassius carassius

6. MAHSEER
There are 4 species of mahaseer.
It has a big head hence it is known as Mahaseer.
They are about 1.5m in length and breed from July to
September.
It requires DO(ppm) 7.8-8.4 and temperature of water
should be between 18.5-27.6.
spawning- does not spawn in stagnant water therefore
induced breeding is applied in ponds.

9. TROUT
Trout are species of freshwater fish belonging to
the genera Oncorhynchus, Salmo and Salvelinus
Trout are usually found in cool (10–16 °C), clear
streams and lakes.
Trout generally feed on other fish, and soft bodied
aquatic invertebrates, such as flies, mayflies,
caddisflies, stoneflies mollusks and dragonflies.
trouts are now acclimatized in the streams, lakes
and reservoirs in Indian waters, particularly in
Nilgiri, Kodai Kanal, Kashmir and Himachal
Pradesh.

12. Scope & significance
Source of income and employment.
Major contribution in the econamy of the state.
The fishes are now available for food and farming.
The importance of coldwater fisheries lies in their unique
biodiversity, valuable germplasm and maintenance of
environmental quality in hills.
Population depends on fisheries sector for food and
livehood.
Hill areas offer good scope for the development of
fisheries both for commercial and sport purposes.
The coldwater fishery resources in India comprise high
and mid-altitude lakes, rivers, streams, their tributaries and
reservoirs dammed across such rivers.

13. CONCLUSION
Coldwater fishes have a huge potential of contributing
towards the fisheries sector.
For this reason coldwater fisheries has also been termed
as "The Sleeping Giant".
Coldwater fishes breed naturally but since some species
have been listed as endangered, therefore artificial
breeding is now being practiced to restore the diversity.
Coldwater fishes forms both the ornamental and
consumable product and hence its protection, enhancement
and maintenance is a must.
