Prakash and Rajesh watching (Rainbow trout) fishes in a small pond at Rhodo valley.
These fishes can survive even at minus degree.
Rainbow Trout:
They are members of the salmon family and, like their salmon cousins, can grow quite large. They average about 20 to 30 inches (51 to 76 centimeters) long and around 8 pounds (3.6 kilograms), but can grow as long as 4 feet (1.2 meters) and weigh up to 53 pounds (24 kg).
They prefer cool, clear rivers, streams, and lakes, though some will leave their freshwater homes and follow a river out to the sea. These migratory adults, called steelheads because they acquire more silvery markings, will spend several years in the ocean, but must return to the stream of their birth to spawn.
Rainbow trout survive on insects, crustaceans, and small fish. Their populations are healthy worldwide and they have no special status or protections. However, they are now considered a non-native pest species in some areas where they have been introduced.
