Differences in predator-inspection behaviour between gravid and non-gravid female as well as between male and female three-spined sticklebacks Gasterosteus aculeatus were investigated. Gravid females confronted with a live rainbow trout Oncorhynchus mykiss showed bolder inspection behaviour than non-gravid ones. The behaviour of gravid females was comparable with that of males, maybe because both face a high risk of predation. The results indicate that antipredator behaviour in female G. aculeatus is not fixed but adjusted to their reproductive state.
