[Coral-List] Lionfish in the Atlantic-Snappers in the Pacific

The introduced snappers did in fact island hop northwest, and southeast, throughout the archipelago. The only island where ta`ape were released was O`ahu, and they dispersed from there.  Most of this was likely larval dispersal, given the distances and depths between islands and atolls, and the rate at which notable populations became established.  Based on records kept by the State of Hawai`i and published reports, a more or less stepping stone pattern of dipersal looks to have taken place. The average rate of advance was about 60km per year, and the snappers are now found essentially throughout the archipelago.
