Aggressive behaviour and energy metabolism in a cichlid fish, Oreochromis mossambicus [PDF]

open access: greenPhysiology & Behavior, 2006
We have investigated the effect of mirror-elicited agonistic behaviour on oxygen consumption in the Mozambique tilapia, Oreochromis mossambicus (Cichlidae). Males exposed to their mirror image showed higher frequencies of both lateral display and tail-beating and escalated aggression more frequently than males exposed to a transparent glass that was ...

Cadmium Induced Adverse Effects on Fry of Oreochromis mossambicus

open access: yesJournal of Tropical Forestry and Environment, 2011
This study investigates the effects of Cadmium (Cd) on fry of the Mozambique Tilapia Oreochromis mossambicus using standard toxicity tests. Fry were repeatedly exposed to five concentrations (0.002 – 2.0 mgl-1) of Cd and survival, growth and swimming ...

Chemical communication in tilapia: A comparison of Oreochromis mossambicus with O. niloticus [PDF]

open access: greenGeneral and Comparative Endocrinology, 2014
In allopatric speciation species differentiation generally results from different selective pressures in different environments, and identifying the traits responsible helps to understand the isolation mechanism(s) involved. Male Mozambique tilapia (Oreochromis mossambicus) use urine to signal dominance; furthermore, 5β-pregnane-3α,17,20β-triol-3α ...
