Description Growth studies are important to determine the total recruitment of fish
with respect to time while information on age and length at first maturity
are essential to assess the spawning stock. The present communication
deals with growth, maturity and mortality parameters of Indian oil
sardine Sardinella longiceps from southwest coast of India. Length at
first maturity of oil sardine was found to be 15.7 and 15.2 cm for male
and female, respectively. Comparison of length at first maturity of oil
sardine with earlier studies showed only minor variations. The growth
parameters L∞, K, and age at zero length (t0) were calculated as 19.8 cm,
1.14 yr-1 and -0.0464 respectively. From the VBG equation, the length
attained at the end of I, II and III year is estimated as 13.79, 17.87 and
18.9 cm respectively. Two peaks of recruitment to the fishery were
observed. The values of total mortality (Z), natural mortality (M) and
fishing mortality (F) estimated are 4.33, 2.7 and 1.6 respectively. The
exploitation rate was found to be 0.37.
