Title Age and growth of the juveniles of Koth
Otolithoides brunneus (Day) in Bombay waters
 
Creator Jayaprakash, A A
 
Subject Sciaenids
 
Description 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.
