Sammanfattning
Five introduced strains of Nile tilapia (Oreochromis niloticus) were tested for growth performance both in fresh- and brackish-water (2 salinity units) environments for 56 days. The BIG NIN, GIFT, Chitralada, "Ruvu Farm" and Silver YY strains with initial mean average weight (+/- standard error) of 96.4 +/- 6.90 g, 104.1 +/- 7.19 g, 137.2 +/- 7.21 g, 53.2 +/- 6.98 g and 95.3 +/- 7.11 g, respectively were used. Individuals were tagged and pooled in hapas (12 mx8.5 mx2 m each), aligned into different ponds (20 mx20 m each). Stocking density of 5 fish/m(2) and 350 g/kg crude protein diet were used. Overall, the average weight gain for GIFT strain was 7.5%, 32%, 45% and 86.5% higher than BIG NIN, Chitralada, "Ruvu Farm" and Silver YY strains, respectively, across both environments. All strains performed significantly better (p
