The time used by tuna bait-boats in catching anchovies used as bait in their operations were examined. The duration of baiting time has not significantly increased but the percentage of trip time spent at baiting increased between 1986 and 1992. Over the same period, the catch per unit effort (cpue) of canoes exploiting anchovies have also steadily increased. There does not appear to be any change in the temporal and geographic distribution of anchovies in Ghanaian waters. Therefore it seems that the increasing percentage baiting time may be due to factors other than the availability of anchovy.
