This case series is appropriate for undergraduate, MBA, executive education, and MBA Exec audiences but is specifically designed for decision analysis, a first-year MBA core course. In the Part I case, Osvaldo Correa, CEO of Salmones Puyuhuapi (SP), must decide how to respond to news that the ISA virus has infected a competitor's salmon farming site. The alternatives include harvesting SP's 900,000 salmon two months early, waiting for the fish to grow and risk losing fish to the virus, and vaccinating the fish. The "harvest now" alternative is evaluated using normally distributed fish weights. It is necessary to account for monthly growth of the fish and mortality to value the ends of the decision tree. Other alternatives, e.g. testing the water, fish, and marine life can be studied with the expected value of perfect information. Vaccination is an example of the value of perfect control.

This case is appropriate for undergraduate, MBA, and MBA Exec audiences but is specifically designed for Decision Analysis and Decision Analysis and Optimization, first-year MBA electives. It is related to but separable from "Salmones Puyuhuapi (A)" (UVA-QA-0749). That A case was about whether to harvest salmon early due to the threat of a virus, and it used a simple approximation for relating the value of a harvested salmon to its live weight. This production planning case addresses in detail how harvested salmon are processed and sold. Here, the plan Elisa Perez develops will determine how much value Salmones Puyuhuapi achieves from a day's harvest of salmon from one of the company's sites in southern Chile.
