Jayaprakash, A A (1976) Age and growth of the juveniles of Koth Otolithoides brunneus (Day) in Bombay waters. Indian Journal of Fisheries, 23 (1&2). pp. 86-96.
The age and growth of the juveniles of 'Koth', Otolithoides brunneus (Day), were determined by three methods: 1) length-frequency distribution 2) scales 3) otoliths. The length attained at the completion of I to IV years of life as deduced from the length-frequency studies were 40.0, 60.0, 80.0 and 95.0 cm, respectively. The corresponding length calculated from scales for the same ware found to be 40.7, 57.8, 75.6 and 91.3 cm. By the time the scales develop one ring the otoliths showed three 'larval rings'. The period of formation of the first scale ring corresponds to that of the fourth ring in the otoliths. The period of formation of the rings in the scales was found to coincide with the winter months, October to February. The formation of the rings may be due to the low temperature prevailing during this pariod. The value of L oo obtained by using Walford's growth transformation is 198 cm. The K and Loo values estimated by von Bertalanffy equation were 0.14 and 206.4 cm respectively.
