Abstract

The catch trends of the windowpane oyster at Yetimoga landing centre
during 1978-81 are described. The instantaneous rates of mortality of Placenta
placenta are estimated as Z = 4.0, M = 1.3 and F = 2.7. The life-span is 3.4
years. The study on the yield in weight per recruit shows that under the current ftof
0.89 year, the yield increases without reaching a maximum with increased F. It
is also observed that maximum yield can be obtained at tc i= 0.8 which is close
to the current value. It is recommended that the present tic and F can be maintained
with advantage.
