Seasonal variations in condition factor and feeding intensity of freshwater Teleost: Ompok bimaculatus, Xenentodon cancila, Puntius sarana and Labeo boggut from Tighra reservoir, Gwalior (M.P.)

Condition factor and feeding intensity of Ompok bimaculatus, Xenentodon cancila, Puntius sarana, Labeo boggut were studied from May, 2012 to April 2013. The condition factor of Ompok bimaculatus was varied from 0.49±0.03 to 0.81±0.13. The maximum mean monthly condition factor of Xenentodon cancila was observed in the month of April (0.59±0.05) and minimum in the month of November (0.21±0.04). Condition factor of Puntius sarana showed variation from 1.07±0.04 to 1.9±0.05 and it was increased in the month of March while decreased in the month of November. The condition factor of Labeo boggut was varied from 1.01±0.13 to 1.87±0.09 and it was highest in the month of April and lowest in the month of December. It was observed that condition factor (K) was higher when fish entered into the maturity period during the month of March and April while in the other months K showed slightly lower values. The gastrosomatic index and hepatosomatic index, both indices were minimum in the months of June and July and maximum in the months of December and January due to availability of good food items.
