Non-SPF shrimp breeding in Ecuador
This article reports on a breeding program focused only on the improvement of growth rates at associate farms in Ecuador. By applying a localized breeding strategy, the program has yielded an average 7.8 percent annual phenotypic gain for commercial growth rates, while survival has remained fairly constant.

SPF shrimp breeding in Brazil
Through a genetic selection program started in 2006, significant advances have been achieved in the development of a specific pathogen-free L. vannamei line in Brazil.

Tank effects impact selection responses in shrimp breeding
Separate family rearing can lead to tank-derived environmental effects that are statistically confounded with full-sib family genetic effects in shrimp breeding.
