Bream (Oreochromis mortimeri) is recognized by the olive green blotches and/or bands on its back and side.

Most people tend to think of bream and tilapia as the same fish. Actually, it is a little-known fact that bream and tilapia are two different species.
They are very similar in both appearance and taste, with both species classified under the Cichlids family.
Tilapia fish are plant or sediment feeders whereas bream tend to be more predatory. Bream will eat small fish, prawns, crabs, worms.
The bream found in Lake Kariba is divided into 3 types:
Rainbow Bream are the Sargochromis Carlottae, also known as the Rainbow Happy.

The Pink Bream species name is the Sargochromis giardia – also known as the Pink Happy. This species is famously known as happies or smallmouths – describing their little mouth.
Kariba bream feed on invertebrates, small fish, and plant material. Interestingly they are an effective biological pest control for snails.
These Kariba fish species play a pivotal role in the local people’s diet and are a good source of income for local fishermen.
Their conservation status by the IUCN report is “Not Yet Threatened”.
