|Pacific white shrimp
have been reported as escaping shrimp farms along the Texas Gulf Coast since
1989. The greatest risk these escapees pose is the introduction of diseases.
In 1995, the Taura virus from South America appeared at a hatchery in Texas
where mortality was 80-90%. At the same time 2 other diseases appeared also.
It is not known how the diseases got to Texas, but shipments of stock shrimp
are moved globally. Another species the giant tiger shrimp (Penaeus monodon)
native to SE Asia have escaped mariculture facilities in South Carolina where
they were quickly collected later that same year 500 km offshore and as far
south as Florida.
