Re: NIH-Aplysia Resource Facility

Dear Dr. Rudman,
Your question about the possible accidental release and introduction of A. californica into local waters is a very important and real issue. When we designed and built the Aplysia Facility in Miami it was one of our most important concerns. Daily, all eggs are removed from the brood stock cages to minimize the possibility of larvae escaping in the effluent. In addition, the discharged water is filtered through a 50 micron filter bag and finally discharged down a 75'deep well.

Larval Bursatella competition in shrimp ponds? That's the least of the problem. I'm confident that a LARGE population would change or affect the phytoplankton bloom, hence reduce available food for the larval shrimp. More importantly, a few good size juveniles will crop down the algal mats and macroalgae (primary productivity) that shrimp pond production counts on for a good crop. For reference, Aplysia eat 20-50% of their body weight per day. Thanks for the interest and hope I've helped

Tom,
Thanks for your instant reply. If you ever feel like sending any news from the Aplysiid world it would be very welcome.
