摘要

The interrelationships among commonly used length and weight metrics aredescribed for swordfish (Xiphias gladius) from the central North Pacific Ocean. Swordfish were sampled by National Marine Fisheries Service (NMFS), Southwest Region (SWR) observers aboard commercial vessels of the Hawaii-based longline fishery during 1994-97 and caught on research cruises of the NOAA ship Townsend Cromwell during 1991-97. The authors' attempt has been to provide complementary data for different users. First and foremost, the described length-weight relationships provide previously unavailable information required for pending stock assessments and life-history studies of swordfish in the North Pacific Ocean. Findings further allow researchers and managers to convert length and weight metrics for comparison with swordfish landings on the U.S. Atlantic seaboard and elsewhere where different metrics are used. Information on monthly fluctuations in condition (weight at length) also should interest Hawaii-based commercial fishermen and buyers.
