Characterisation of wild and cultured Oreochromis shiranus in Malawi
Abstract

Oreochromis shiranus is a Malawi indigenous tilapia fish species.
The aim of the study is to characterise the species phenotypically
and genotypically within and between wild strains, unimproved
and improved cultured strains. Phenotypic characterisation
studies will be carried out using whole fish specimens while
genotypic variation analysis will be done through DNA
extraction, PCR and electrophoresis processes using fin-clips/
body tissue preserved in absolute alcohol with the help of gene
markers. It is hoped that the results will be incorporated in a
breeding programme to improve stunted and slow growth
presently reported in many culture practices of O. shiranus in
Malawi.
