| Abstract: | When presented
with stimulus shoals of siblings and conspecifics in equal number, P. sarana subnasutus were able to discriminate their siblings and
preferred to associate with them. Given a choice between large shoal and a
small shoal consisting of siblings, the juvenile fish preferred to associate
with larger stimulus group to the smaller one. However, juveniles traded off
their preference for sibling shoal with large non-sibling conspecific stimulus
group, regardless of the possible benefits gained from associating with sibling
shoals. The results reveal the ability of fish to discriminate their siblings
during their early developmental stage and the overriding influence shoal size
in the context of shoaling preference in P. sarana subnasutus. |
