Abstract

MSY, gro·wth, selection and mortality parameters of Otolitlwitles hiauritus have been
worked out from data collected by MFV Saraswati of CIFE, and length frequency data from
Ferry Wharf, Sasson dock, and Versova fish landing centres of Bombay. Values of Loc, K,
and to obtained fmm lenght ft·cquency study are 1572mm, 0.2633/yr and 0.0289 yr respectively,
and of weight grmvth parameters are Woc = 10067g, K= 0.03904/yr and to = 0.0137yr.
Selection parameters arc Lr + 150mm, tr + 0.4167 yr lc + 240mm and tc = 0.6367yr. Selection
factor (K) for codend worked out to be 12. Based on Z=0.6486, the MSY of Otolitlwides
biauritus off nOiihl\'est coast of India is assessed as 1,802 tons. which is slightly higher than
the current catch level of 1,634 tons.
