The paper emphasizes on the several
attempts made to raise the brackish water tilapia
species, Tilapia guineensis both on an experimental
and production basis by researchers and fish farmers
in Nigeria. Besides, the aquaculture potentials of
Tilapia guineensis have been reported by several
authors. However, problems exist which are not found
with the culture of other tilapia species. Even under
most favourable conditions (e.g. the monosex culture
of Tilapia guineensis), a poor growth rate and a
mediocre feed conversion do not presage profitable
aquaculture exploitation. The present review therefore
throws light on areas of further research to enhance
the growth performance of Tilapia guineensis with
emphasis on fish larvae nutrition and first feeding
(development of bio-encapsulated feed for larval fish
based on nutritionally enriched nematodes and Calanoid
copepods), digestibibilty of the feed ingredients,
elucidation of the dietary protein requirements,
improved culture technique through the use of the
Recirculating Aquaculture Systems and the adoption
of the most recent technology (The YY Male
technology) that produces Genetically Male Tilapia
through genetic manipulation. Specific recommended
areas for further research are also proffered. |
