Study on biometrics and biology of Rohu, Labeo rohita from Harike wetland - Ramsar site

Armaandeep Kaur, Surjya Narayan Datta and Grishma Tewari

Present study was carried out in Harike wetland, an internationally recognized Ramsar site (31°08′N to 31°23′N) to evaluate the biometric parameters and biology of one of the economically important fish Rohu, Labeo rohita for a period of September 2016 – February 2017. Average length was recorded 58.2 cm, whereas, average weight recorded 2600.0 g. Negative algometric growth was observed with ‘b’ value ranged from 1.455 to 2.761 and condition factor (K) 1.06. Gonadosomatic Index (%) in male and female was recorded highest in the month of September and lowest in the month of October. Hepatosomatic Index (%) was recorded highest in the month of October and lowest in the month of September. Gastrosomatic index (%) in male and female recorded highest in the month of September (1.56 and 1.81) whereas, it was lowest in the month of January (0.34 and 0.86). Stomach content and relative length of gut (RLG) of L. rohita indicating fish is herbivore in feeding habit. Based on biometrics and biology study it can be concluded that a sufficient number of mature and healthy stock of L. rohita are available in Harike wetland to sustain the stock in future.
