Abstract:
Soundproductionhasbeenwidelydescribedforterritoryholdingfish,includingcichlids,
duringreproductiveandagonisticactivities.MalesoftheAfricanmouthbroodingcichlid
Oreochromismossambicusdefendterritorieswheretheydigpitstoattractfemales.Sound
emissions,aseriesofpulses,werestudiedinthisspeciestodeterminetheirassociationwith
agonisticandcourtshipacts.Focalobservationsonvisualandacousticbehaviourwere
carriedoutfor8territorialmalesofvarioussizesbelongingto5mixedsexgroups.The
numberoftimeseachbehaviouralactoccurredwithandwithoutsoundemissionwas
scoredandtestedfordependence.Agonisticandcourtshipepisodeswerealsoquantified
andcorrelatedwithsoundproductionrate.Courtshipepisodeswerecategorisedintolow
(either'tilt'or'lead'occur)andhigh(either'tailwagging'or'quivering'occur)rank
episodes.Soundproductionwassignificantlyassociatedwiththecourtshipacts'tail
wagging'and'quivering'inallfishandwith'pitcircling'and'dig'inlargermales.Courtship
episodeswerepositivelycorrelatedwithsoundemissionrate,thoughonlyforhighrank
episodesinsmallindividuals.Soundproductionwasnotsignificantlyassociatedwith
agonisticbehaviour.
