Obligate and opportunistic parasites play a critical role in determining the productivity, sustainability and economic viability of global finfish aquaculture enterprises. Without stringent and appropriate control measures, the impacts of these pathogens can often be significant.
Estimating the true impacts of each parasite event, however, is complicated, as costs can be affected by a diverse assortment of environmental and management factors. The factors can range from direct losses in production to the more indirect costs of longer-term control and management of infections and the wider, downstream socioeconomic impacts on livelihoods and satellite industries associated with the primary producer.
Certain parasite infections may be predictable, as they occur regularly, while others are unpredictable because they arise sporadically. In each case, there can be costs for treating and managing infections once they are established, but for predictable infections, there also are costs associated with prophylactic treatment and management. This article provides an overview of issues and estimates of economic impacts drawn from a larger study.
