Designing a biosecurity plan for shrimp aquaculture, part 2

The objective of a contingency plan is to quickly recover production through rapid initial response and effective implementation of biosecurity measures. Such plans depend on whether the detected pathogen or disease is exotic or endemic, its potential economic impacts and
