Ecology Summary - Oreochromis alcalicus

Langue:

Réf. Princ.	Trewavas, E., 1983
Remarques	This species inhabits waters rich in sodium and chlorides with temperatures 16-40°C (Ref. 11287). Female is a mouth brooder which migrates from nest to nest while the male prepares the nest waiting for the female to deposit her eggs. Males defend the nest from juveniles and other species which feed on the eggs which fall from the female's mouth (Ref. 11288). Being strictly herbivores, the species survives on algae, mainly of the family Cyanophycea. The juveniles are carnivores feeding on invertebrates, eggs and larvae. Maximum feeding activity occurs at night (Ref. 11289). Very little is known about the growth of this fish.
