Thai Red

Chitralada

Our original and still ever popular strain of Nile tilapia.

Origin:

Introduced into Thailand in 1965 when the Emperor of Japan gave 50 fish to H.M. King Bhumibol. These fish were initially bred at Chitralada Palace, hence the name. Nam Sai acquired the fish in 1994 from the Asian Institute of Technology, Bangkok.
Growth: Very fast grower to 250g, but slows down somewhat over 500g. In 6 months (from 0.2g) attains 400g in fertilized ponds and 750g in fed ponds or cages.
Shape: Wide, long and narrow (looks big when placed side down).
Fillet yield: Found to have highest yield of all strains under high density tank culture in Holland.
Colour:  Natural Nile tilapia colouration, becomes lighter or darker to camouflage the fish against the background.
Maturity: 6 months.
Egg yield: 30-50 eggs/m2/day in spawning hapas
Disease resistance: Moderate

GIFT

Presently the most widely cultured strain of Nile tilapia in Thailand.

Origin: The Genetically Improved Farmed Tilapia or GIFT strain was produced by the International Centre for Living Aquatic Resources Management (ICLARM, based in Philippines) from a wide genetic base of wild and farmed strains. Nam Sai acquired GIFT generation 5 in 1997 and generation 9 in 2000 from the Thai National Aquatic Genetics Research Institute (NAGRI). Nam Sai has now merged both generations into a single strain.
Growth: Similar to Chitralada.
Shape: Short and fat, stocky body (wide girth makes it appealing when sold live).
Fillet yield: Despite being fat, fillet yield is lower than Chitralada possibly due to having a large body cavity.
Colour:  Natural Nile tilapia colouration.
Maturity: 7 months.
Egg yield: 30-50 eggs/m2/day in spawning hapas
Disease resistance: High
Nam Sai Red Hybrid

Big Nin

A new faster growing strain of Nile tilapia.

Origin Reported to be developed from the GIFT strain and acquired by Nam Sai in 2004 from a hatchery in the Philippines.
Growth: In 6 months (from 0.2g) attains 450g in fertilized ponds and 800g in fed ponds or cages.
Shape: Short and fat with a wide girth.
Fillet yield: Similar to GIFT.
Colour:  Natural Nile tilapia colouration.
Maturity: 6 months.
Egg yield: 30-50 eggs/m2/day in spawning hapas
Disease resistance: Moderate and higher than pure strains. Good resistance to Streptococcus agalactiae.
Nam Sai Red Hybrid

Nam Sai 2

An F1 hybrid with plenty of vigour.

Origin This is an F1 hybrid and not a pure strain. It is created by crossing GIFT (high disease-resistance) and Big Nin (grows fast to a large size).
Growth: Very fast all the way. In 6 months (from 0.2g) attains 430g in fertilized ponds and 780g in fed ponds or cages.
Shape: Short and fat with a wide girth.
Fillet yield: Similar to GIFT.
Colour:  Natural Nile tilapia colouration.
Maturity: Not used for breeding.
Egg yield: N/A
Disease resistance: Moderate and high.
