摘要：
A study on age, growth and stock characteristics of the Indian mackerel Rastrelliger kanagurta (Cuvier) was made from Sohar coast between 2007 and 2009. The length-weight relationship for the species can be expressed by the common formula, W = 0.0035TL(3.3881). The growth parameters of R. kanagurta were L-infinity = 3 4.00 cm, K = 0.86 y(-1) and t(0) = -0.06 y. The total mortality (Z) was 2.84 y(-1), the natural mortality rate (M) and fishing mortality (F) were 1.58 and 1.26 respectively. The exploitation rate (E) was less than 0.5. The estimates of MSY stood at 1512 t by Cadima's formula. The predictive Thompson and Bell analysis indicated scope for marginal increase in Indian mackerel landings and the estimated MSY and corresponding F were 1,576 t and 1.4 respectively.
