Welcome to the forum. Please perform your swordfish longlining 'research' operations outside of the area in which swordfish longlining previously destroyed the swordfish population to the point that it took decades to rebuild to where it could sustain viable recreational and buoy gear fisheries again.
No matter what conclusions you derive from your results, suffice it to say we alraedy know what happens when longliners enter the Florida Straits closed zone - a handful of individuals profit, and the entire remaining South Florida fishing community loses an entire fishery.
Couldn't be more black and white. Longliners belong elsewhere.
Everyone (save a handful of short-sighted profiteers) would be better off if you focused your scientific talents elsewhere.
