natural (M) and fishing mortality coefficient (F) were estimated as 2.66, 0. 77
and 1.89 respectively for the 1995 to 1997 period. The exploitation rate (U) and
exploitation ratio (E) were estimated as 0.66 and 0.71 respectively, which is
beyond the optimum Thursreduction in the fishing effort for this stock along
