Gross morphology of the alimentary canal and seasonal variation in feeding of Noemacheilus montanus (McClelland).

Noemacheilus montanus (McClelland) is a bottom feeder Omnivorous fish of Garhwal hillstreams. The alimentary canal is short and the stomach consists of a corpus and a pylorus portion. As it consumes more animal food than the vegetable food, it may be better called Carni-omnivore. The study of GSI for different months revealed that the feeding intensity attains 2 peaks during a year, first in December and second in June. The change in feeding intensity may be correlated with the availability of food items in nature.
