Abstract

The Von Bertalanffy growth parameters {orXeiognathus jonesi are estimated as: L~ = 146.617mm and K = 0.917 per year. The coefficient of total mortality (Z), natural mortality (M) andfishing- mortality (F) rates are estimated. The length-weight relationship of the fish isW= 0.000030335 ^^ 2.887. Beverton and Holt yield per recruit analysis shows that an increasein Lc results in better yield per recruit. The estimated average annual stock ranges between8,800-9,100 tonnes and the average standing stock between 1,700-1,900 tonnes.
