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.

One of the largest shrimp maturation operations in Ecuador is working with five major shrimp producers to improve growth rates.

A study in Brazil found that the growth superiority brought about by within-family selection of tested shrimp transmitted to the next generation of animals.

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.

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

In Brazil, shrimp hybrids – crosses of imported specific pathogen-free lines and a genetically improved and locally adapted line – outperform their parents.

Combined analyses of SPF shrimp from six imported lines and one commercial genetically improved line in Brazil found excellent winter performance.

Breeding efforts at Aquatec Genearch Aquacultura in Brazil have centered on specific pathogen-free white shrimp lines imported from the United States.

Studies show variability for shrimp carcass and meat quality traits, especially fat quality. Selection for growth may lead to increase in yield.
