Red tilapia strains

Origin:   Introduced into Thailand in the seventies and kept at the National Inland Fisheries Institute (NIFI)

Shaped:   Short and round with big girth.

Fillet yield:   Not known.

Colour: Was originally pale, but is now close to the red colour of the Taiwanese red. Very few black spots, but red and white colouration is still a little patchy.

Age at maturity: 6 months.

Egg yield: High

Survival: Low compared to Nile tilapia in sex reversal, but otherwise good.

Origin:   Acquired from a local mixed sex hatchery who imported a few fish from Taiwan in 1997. Was previously interbred with Nile tilapia and colour was very poor. Nam Sai spent 4 years improving the colour of this strain before introducing it to the Thai market in 2001.

Growth:   Grows very similar to the Thai red. In 6 months (from 0.2g) attains 700g in fed ponds or cages (not reared in fertilized ponds),

Shape:   Longer, not quite as fat, but still round like the Thai red.

Fillet yield:   Not known.

Colour:   Vivid red with very few black spots. Colouration is still a little uneven due to varying shades of red and white.

Age at maturity:   6 months.

Egg yield:   High

Survival:   Low compared to Nile tilapia in sex reversal, but otherwise good.
