Selection for IMNV Resistance


In 2004, Queiroz Galvão Alimentos, S.A. (QGA), a 960-hectare shrimp farm, began working with Concepto Azul, a company the specializes in aquaculture biotechnologies, to implement a selective breeding program that addresses the ongoing impacts from the infectious myonecrosis virus (IMNV).  Broodstock were selected for resistance to IMNV, growth and the ability to withstand stress.


When challenge with IMNV for 60 days, mean survival rate in ponds increased from 3.2% in the first generation to 55.3% in seventh generation!


OGS also operates its own processing plant and has a hatchery with a monthly production capacity of 300 million postlarvae.
