okay. i'm not sure but i think i found the link to what was being mentioned about nurse sharks being illegally kept.
http://www.nmfs.noaa.gov/sfa/hms/Compliance_Guide/Rec/Rec_Compliance_Guide_Total.pdf
please let me know if this is right. i think that it is saying that if you are fishing for recreation, that most sharks would have to be thrown back if under the minimum size "MINIMUM SIZES
Most authorized species of sharks that may be kept recreationally have a
minimum size of 54 inches (4.5 feet) fork length, which is the straight-line
distance between the tip of the shark’s nose and the fork of the tail (see image
below). The only exceptions are for Atlantic sharpnose and bonnethead
sharks, which have no size limit. Sharks that are under the minimum size limit
cannot be possessed and must be released using a method that maximizes their
chance of survival, without removing them from the water." it also states that "Recreational fishermen must land sharks with the head, fins, and tail naturally
attached. Sharks may be gutted and bled by making an incision at the base of
the tail as long as the caudal (tail) fin is still naturally attached by at least a
small flap of uncut skin." so according to this, in catching a shark with the intentions of utilizing its body parts, a minimum size limit must be met. please let me know if i'm wrong. its late...i'm tired..and it took me too long to even find this. now i'm extremely curious to know.
