We have an invasive West Indian species setting up shop here in FL. Called the Manatee. Capt Ron ... Blago, has been writing on the subject for 30 yrs or so. Trust me this dude knows his sheit.

Apologize for the poor quality of the scan. Best I could do with the equipment on hand. To view any of Capt Ron's previous musings please visit WaterLife magazine. His articles are usually 'bout 5 pages in.
