Abstract

The length-weight relationship and the relative condition in the ribbon fish Trichiurus
lepturus were studied in 185 males in the size range 355-960 mm and 143 females
in the size range 352-1090 mm collected during the period August 1966 to May 1969.
Analysis of covariance of the two regressions showed no significant difference in the
slopes. Apparently the sexual cycle does not seem to affect the relative condition of the
fish, at least directly, while high intensity of feeding influences the K„ There is a sudden
fall in the value of relative condition at 625 mm fish length, and maturity studies indicate
that over 90% of fish attained sexual maturity at this length.
