Shinn A, Pratoomyot J, Bron J, Paladini G, Brooker EE & Brooker A (2015) Economic impacts of aquatic parasites on global finfish production. Global Aquaculture Advocate, September/October 2015, pp. 58-61. http://pdf.gaalliance.org/pdf/GAA-Shinn-Sept15.pdf
Parasites generate costs for managing infections as well as prophylactic treatment in finfish aquaculture. Based on estimated hatchery losses to parasitism of 20%, the authors estimated annual global loss of juvenile fish to parasites at U.S. $107.31 million to $134.14 million. Assuming parasites are responsible for losses of 1% to 10% of harvest-size fish, the value of these fish was estimated at $945.00 million to $9.45 billion. Combining the hatchery and growout figures, the parasites’ annual cost was tentatively estimated at $1.05 billion to $9.58 billion.
