Everyone,
The question of why do they allow fishes, but not inverts is a good one. I do not have the complete story, but it goes back to yaers ago when regulations began. Not all fishes are allowed, but most reef fishes are. There were two rerasons some fishes were excluded on the import list. 1) a particular group could have a greater destructive capability such as sharks or scorpin fishes, and 2) people at the public meetings during the time of restrictions did not ask for a particular group to be put on the list.
Now, if you simply ask for a permit, you can bring in any of the allowed families. Has this help with people being responsilble. Of course not. There have been many sitings of non native fishes around Hawaii. There are at leats 3 species of fishes (that I know of) that have been intentionally introduced such as (C argus, L. fulvus, and L. kasmira). The reason was people like to fish for them (years ago). Now they are considered trash fish or known for cigratera poisoning. They are also causing havoc on local species such as Opakapaka (pink snapper) and others. There have been sitings of lemonpeel angles, non native damsels, and also another species of angel fish (I can't remember which species) all in the area of Waikiki.
This is just counting the marine species. Hawaii's stream communties are permanently destroyed due to intentional aquarium releases.
Now, should we ignore it because things just happen. Well, I tell you what, if there was something we could do now about the rat or mongoose or cat problems, we sure would do it. So, why don't we take care of the introduced corals (the mushrooms I spoke of earlier) while we still can. It may seem like it is not much, but you have to stop and think about the amount of endemism Hawaii has. And, marine invertebrates play an important role in Hawaii's unique ecosystem.
For anybody interested here in Hawaii, there will be a presntation at the HAwaii Kai public library next Saturday of introduced species in Hawaii. It is very alarming to actually hear how many species have been introduced to our state. E-mail me for details.
Aloha
Tony
