Title Population dynamics of the Bombay duck, Harpodon
sehereus (Ham.), off Saurashtra coast

Subject Population Dynamics
 
Description The growth parameters estimated for H.nehereus are K=0.7618, L =425^ mm and t„=0.00789 yrs. The
total mortality coefficient (Z) varied between 2.331 and 3.168 during 1979-'84. Yield per recruit (Yw/
R) was estimated at 10.819g at F max 1.048. The size at first capture is very low (0.21 year), however,
there is no possibility to fish dose to optimum age at exploitation (ty) in view of low catch registered
in the-higher sized mesh dal net of 30 and 40mm. The estimated maximum sustainable yield (MSY) was
at 44,0661 and the average yield was 44,0641 along the Saurashtra coast. In view of high Z during February
to May and low percentage of commercial sized fish, suitable management strategy to be adopted are
discussed in the paper.
