Summary The present study provides the length–weight relationships ( LWR s) for four pelagic fish species belonging to three families sampled with the longline gear from the tropical Northwest Pacific Ocean. The sampling was conducted by the Chinese longline observers from June 2011 to September 2012 and the fishes were captured by commercial pelagic longline fleets. The circular size 4.0 sun‐C‐37 Japanese tuna hook design was used for this fishing operation. Length–weight relationship for one of these species is unknown to Fish Base. Additionally, a new maximum length of one fish species is identified in the study.
