Now we have green mussels in Tampa Bay and the Gulf of Mexico. In the summer of 1999, a power plant in Tampa reported finding them in their intake pipes. Since then they have spread out of Tampa Bay and into the Gulf of Mexico along southwest Florida. It is well established and has survived water temperature much below where it came from. This was probably not an aquaculture introduction but I thought it worth mentioning because of the potential for it to become one now that it’s here.  This species has also invaded Venezuela, Trinidad, and Jamaica in the Caribbean Sea.
