Abstract
Buntbarsch. Männchen in Prachtfärbung beim Bau einer Laichgrube. Balz des Männchens: Schwanzschläge schräg über dem Kopf des Weibchens. Mit zunehmender Laichbereitschaft Beteiligung des Weibchens am Graben, Scheinablaichen.
In this film, the most important mating movements of the female Tilapia nilotica have been caught. There are no lasting conjugal ties between the male and female of this species; they come together only to spawn and separate again thereafter. Certain colourings and movements facilitate, or first make possible, mutual recognition of the sexual partner.
