Information: |
Inhabits lakes, swamps
and rivers. Widespread in both shallow and deep water. Probably
associated with rocky bottoms/coarse substrates. Mostly active during
the night and the twilight hours. Juveniles may frequent exposed
rocky shores. Feeds on insects, crustaceans, mollusks and fish.
Some debris and vegetable matter may also be ingested. Moderately
important as a food species in Lake Victoria, but becoming rare
with the appearance of Nile perch. Catches decreased strongly in
Lake Victoria after the lates upsurge. Predation by lates
and competition with lates (for haplochromines) may have
played a role in the decline. A notably recovery in waters between
3m and 6m depth in Lake Victoria has been reported. Second most
important food species in Lake Edward, Congo |
