Invasion of Tropical Fish Could Threaten Native Species


“Last summer, Narragansett Bay could have been a scene from Disney’s
animated film, “Finding Nemo.” An unusual number of tropical species were
found in the bay, including butterflyfish, bluespotted cornetfish,
Portuguese man-of-wars and the first lionfish documented in the bay.
There also were abnormally high numbers of subtropical fish, such as
inshore lizardfish, that are occasional visitors from the south.

Local fisheries managers are keeping an eye on these southern species
because they have the potential to negatively impact native fish
populations of the bay. The watch will be on again this year."
