Performance of genetically improved farmed tilapia (GIFT)under mono and mixed cui ture with silver barb (Barbodesgonionotus) in south-west Bangladesh
2008
A participatory on-farm trial was carried out to evaluate the production performance of
GIFT (genetically improved farmed tilapia) strain of Oreochmis sp., either alone or
with silver barb (Barbodes gonionotus), in six rain-fed freshwater ponds of coastal area.
There vvere two treatments; (i) GIFT alone at a stocking density of 24,700/ha (T1) and
(ii) 1:1 combination of GIFT and silver barb (T1). Each of the treatments had three
replications. A significantly (pmonoculture, compared to the total production of 3480.38 kg/ha of GIFT
and silver barb. In the 1:1 combination treatment, the production of GIFT (2036.06
kg/ha) was also higher than that of silver barb (1444.32 kg/ha). The results reveal that
GIFT monoculture can performe better in rain-fed seasonal freshwater ponds of southwest
coastal areas.
