Veggie-Fish in a nutshell
BREEDING NUCLEUS

Produced since 1996 in the Breeding Nucleus Rei da Tilápia, located in Mostardas, Rio Grande do Sul. In 2019 we are producing the Generation 28 (G28).

- 24+ years in continuous operation (since 1996);
- Fully documented;
- 50+ families and preparing the 28th. Generation;
- Veggie-Fish is selected in Bioflocs since 2002;
- “It is likely to be the tilapia genetics with the highest penetration in Americas, 5.8% of the world” (Source: Inocap Report/Study - Norway, 2014);
- Main clients: Hatcheries in Latin America, China & Thailand;
- The latest 14 generations (since 2002) were produced in bioflocs (fully controlled environment), as a result, heritability was quadrupled nulling environment effects;
- Several hybrids of four species of Oreochromis are used, not just the Nile Tilapia (= multiplication of gene pool);
- Hatches interval between all families are 3 to 5 weeks, which guarantee better selection results.
SUPER-HYBRID
Veggie-Fish is a hybrid Tilapia line, with the following species:
(1)Oreochromis niloticus (Chitralada + GIFT + GST ) + several African tilapia species:
(2)Oreochromis angolensis,
(3)Oreochromis andersonii, and
(4)Oreochromis mossambicus.

Pedigree of nine generations of Veggiefish produced in Bioflocs, G15 - G24.

Example of the Male 34 (M34) pedigree form Geration 24 (G24) during 2015.
Heritability (h2) for growth in Bioflocs in the 6 last generations of Veggie-Fish:
G22 = 0.56 (2013)
G23 = 0.58 (2014)
G24 = 0.47 (2015)
G25 = 0.52 (2016)
G26 = 0.60 (2017)
G27 = 0.59 (2018)

*The average h2 in the last 15 years was 0.56 ± 0.07, very high especially when compared to 0,12-0,24 typical of other breeding programs also originated from the GIFT material.
The UFMG also reported h2 up to 0.70 en bioflocs (2014).
