A Vision of "Compatibility"
Oyster farming in Arcachon, France, where a Herpes virus
outbreak caused 80% of juvenile oysters to die.
High density shellfish farming
is not without risk.
"The Process"
"Pressing the flesh yields instant results over wine and oysters.
Our legislators have a healthy appetite for good oysters
and they want to help us
create more green jobs in rural coastal areas." (ECSGA)

High density shellfish farming of non-native species is not without risks. As any parent of a child in school knows, classrooms are breeding grounds for virus, spreading from one child to the next and home. In a natural environment of native species growing in natural densities, disease resistance has evolved over generations. Shellfish are not competing with each other for resources so are not stressed in their various life stages, continuing to remain healthy and thrive.

Contrast this with the die offs from the Herpes virus in the high density plantings found in France. Contrast this with the die offs of the non-native Pacific oyster larvae in "hatcheries" from deep ocean upwellings in the northwest, which other species of oysters are able to cope with. Contrast this to the "Pacific oyster mortality syndrome" in Australia which overnight decimated the Pacific oyster population. [click here for article]
As with net pen fish farming, and any other highly concentrated population of species, rapid outbreaks and die-offs increase dramatically. "The Vision" does not come without risks. "Pressing the flesh" only risks spreading disease. Are shellfish politics healthy?
