Summary An investigation of catches of 12 commercial fish species and species groups from the Nigerian inshore trawl fishery between 1971 and 1987, indicated that total catch‐per‐unit effort (CPUE) of all species was less variable among these years than the CPUE of most individual species or species grous Some possible causes for the large fluctuations in the abundances of the single species or groups are Jsiussed.
