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).
