Description Exhippolysmata ensirostris fonned 27% of the non-penaeid prawn landings at Nawabunder, a
major dol net centre in Saurashtra. The peak landing period is from October-December with an annual
landing of 302,2 t during the period 1983-86. The growth parameters are Lα 105.84 mm, t, =
—0.09 month and K = 0.193 on monthly basis. The total mortality coefficient, ‘Z' for the three
year period varied from 8.39 to 11.35. The natural mortality] coefficient, is 3.2. The MSY, calculated
from the yield per recruit analysis is 334.6 t which is close to the present yield and the exploitation
rate is 0.69. In spite of hiigh exploitation rate, the fishery has sustained as the exploited
stock consists of large size adults with size at capture (Ic = 73.0 mm) which is much higher than the
size at 50% maturity (Lt»i 50 = 58 mm).
