Nile tilapia strains
GIFT
Big Nin
Mag Nin
Prominent point
Presently the most widely cultured strain of Nile tilapia in Thailand.
A faster growing strain of Nile tilapia.
A fast-growing strain with a short & thick body shape.
Origin
Produced by the International Centre for Living Aquatic Resources Management (ICLARM, based in Philippines) from a wide genetic base of wild and farmed strains.
Reported to be developed from the GIFT strain and acquired by Nam Sai from a hatchery in the Philippines.
It is created by crossing a developed line of GIFT improved for growth (high disease-resistance) and an improved Big Nin line (grows fast to a large size).
Growth
400 g in 6 months (from 0.2 g) in fertilized ponds and 740 g in fed ponds or cages.
450 g in 6 months (from 0.2 g) in fertilized ponds and 800 g in fed ponds or cages.

Red tilapia strains
Thai Red
Taiwanese Red
R2 Red
Prominent point
Fat and round body, fast growing
Vivid red and relatively disease resistant
Fast growing, nice body shape, big girth, vivid red and relatively disease resistant. Used for all of Nam Sai’s red tilapia monosex production.
Origin
Introduced into Thailand in the seventies and came to Nam Sai from the Thai National Aquatic Genetics Research Institute (NAGRI) in 2000.
Acquired from a local hatchery who imported a few fish from Taiwan in 1997. Nam Sai spent 4 years improving the colour of this strain before introducing it to the Thai market in 2001.
This is an F1 hybrid which created by crossing two lines. One line is a developed strain based on the Thai red and the second line is based on a developed Taiwanese red resulting in some hybrid vigour.
Growth
(Not reared in fertilized ponds in Thailand)
730 g in 6 months (from 0.2 g) in fed ponds or cages.
700 g in 6 months (from 0.2 g) in fed ponds or cages.
