Non-SPF Shrimp Breeding In Ecuador:Alternative Approach Successfully Addresses Localized Conditions

摘要

Following its devastation by white spot syndrome in 1999, Ecuador's shrimp aquaculture industry took a unique approach to recovery. When the specific pathogen-free paradigm was standard for global shrimp production and health programs, local programsbegan deliberately breeding from infected white spot survivors. This article reports on a breeding program focused only on the improvement of growth rates at associate farms. By applying a localized breeding strategy, the program has yielded an average 7.8% annual phenotypic gain for commercial growth rates, while survival has remained fairly constant.
