aquarium concerns

Thank you for the observations.  Yes, we removed 2 adult Batfish in a
cooperative effort with New England Aquarium and Dynasty Marine in Marathon.
The FKNMS mostly observed the quick capture of the 2 fish.  There was a third
adult Batfish but it escaped capture and remains at Molasses Reef.  Although
these fish had been at Molasses for some time (years) we felt the need to remove
these exotics to Caribbean Reefs.  The two fish are now main attractions in the
main aquarium at the New England Aquarium serving as "poster fish" for the cause
of the woes of "exotic introductions."  It is prohibited to release any exotics
in the waters of the FKNMS and we would like to get the word out that exotics
should not be released in the wild , regardless if it is a Sanctuary or not.

While it may seem like a minor issue compared to everything else that is
affecting the health of coral reef communities, it is one thing we can affect,
hopefully through education.

Thanks for the opportunity to put this work out and thanks to Forrest Young of
Dynasty Marine and Holly Bourbon of the New England Aquarium for their
partnership and initiative on this project.

Cheers, Billy
