Abstract/Description: | At Waltair, the average size of Tachymrus tenMbpinis during 1973-76 was 17.5, 23.7, 29.5, 35.5^aiid 39.5 om at the end of 1.0, 1.5, 2.0, 2.5 and 3.0 years respectively. The back-calculated lengths of fish at the time of formation of rings in tile opercular bone were 11.16, 18.74, 24.64, 30.03, 35.70. 40.09 and 44.01 cm at tlie end of 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 and 3.5 years respectively. The mean lengths of fish with II to VII rings in the otolith were 17.9, 25.2, 30.4, 35.4, 39.7 and 42.6 om lespectively. There was, thus, a close agreement in the lengths derived fnom all the three methods at diffeiient ages. The growth rings in the opeircular ibones and otoliths are formed twice a year in June and December and poor feeding is probably the causative factor for the formation of rings, von JBeirtalinffy growth data obtained from the present studies and the calculated values were in close agreement with tho^e observed. |
