Abstract
94 words
This research determined age and growth of Nile perch (Lates
niloticus) from Lake Victoria commercial catches using
transverse-sectioned sagittal otoliths. Marginal increment
analysis of the otoliths indicated bimodal deposition of annuli
over a 12-month period, with the highest opaque zone deposition
corresponding to the two seasonal peaks of rain (i.e. March to
May and September to November) characteristic of this
equatorial region. A difference in growth rate between male
and female Nile perch was observed with the females having
faster growth rates and reaching a large size at older ages than
their male counterparts.
