摘要
In this study we addressed five questions concerning kin recognition and shoaling in threespine stickleback Gasterosteus aculeatus fry. Our results were: (1) fry distinguished between similar-aged sibs and non-sibs when tested at 18, 30 and 45 days of age, (2) fry reared with maternal half-sibs distinguished sibs from half-sibs; fry reared with paternal half-sibs did not discriminate between paternal half-sibs and either sibs or non-sibs, (3) the ability to discriminate sibs from non-sibs did not require experience, but the strength of the shoaling preference was modified by events early in life, (4) fry spent more time near kin when a predator was present and (5) fry did not distinguish between non-sib conspecifics and heterospecifics.
