Abstract: | Laboratory-bred juvenile three-spined sticklebacks from 11 sibshipsdid not
prefer to shoal with their siblings when they were offeredthe choice between
odor from unfamiliar siblings and non-kinin a fluviarium, although the power
for finding a significantpreference was very high (0.99). The test fish
preferred theside where odor from the heavier shoal was supplied; this shows
thatthey could appreciate odor cues from conspecifics in our apparatusand
should have preferred their siblings if such a preferenceexists. Our results
are compatible with theoretical predictionsbut are at variance with previous
findings by other authors.We used independent replicates in a blind protocol
with strictrandomization of fish and procedures. |
