Introduced Species and Bivalve Aquaculture
How is the farming of bivalves related to invasive species?
Aquaculture is a major source of non-native species, and
these same invaders negatively impact aquaculture.
- Aquaculture is one of the fastest growing sectors of food production, but it has historically been he second leading source of introduced marine species.
- Our review of published literature and databases found that there are more than 63 species of bivalves in aquaculture.
- ~24% of bivalve species in aquaculture are grown outside their native range and over half of those have escaped and established wild populations.
- There are more than 39 non-bivalve species unintentionally introduced to new environments by bivalve aquaculture, including many species that have negative impacts on aquaculture itself (e.g., the slipper limpet, Crepidula fornicata, or the oyster drill, Urosalpinx cinera, tunicates, macroalgae).
- Reducing the introduction and spread of nonnative species will benefit the aquaculture industry, managers, protect biodiversity and help conservation efforts.
- Best practices to prevent accidental transfers of species, include selecting sites for aquaculture and methods that will minimize potential fouling, cleaning or cycling of all boats, gear, and equipment that comes in contact with the water, and reporting all suspicious organisms found in an area to allow for early detection.
