Title Dynamics of the threadfin bream, Nemipterus
japonicus exploited off Karnataka

Subject Demersal Fisheries
 
Description The growth parameters of Nemipterus japonicus exploited from the Arabian
Sea off Karnataka are estimated as LM = 33.0 cm and K=1.0 yr1. The approach
using data after correction for selection gives better estimates when compared
with the estimates from uncorrected data. The M estimated was 1.87 and the
mean Z value 5.65 with the exploitation rate of 0.68. The virtual population
analysis reveals that the maximum fishing mortality occurs at 25.5 cm. The
Thompson and Bell analysis shows that the present yield of 3,416 t can be
increased to the MSY level of 3, 5011 by increasing the effort by 10 % whereas
the MSE would be at 80 % of the present fishing effort.
