DEPARTMENT OF FISHERIES REGULATIONS

All pleasure boats entering the Bahamas must purchase at their first
Port of Entry a $20 fishing permit per trip.
Non-Bahamians are restricted to hook and line fishing only, with a maximum of six lines in the water.
Become familiar with bag limits:
Vessels with a valid fishing permit are allowed 20 pounds of scale fish, 10 conch, and six crawfish (in season) per person, at any time.
A combined total of six fish per person per vessel of kingfish, dolphin, and wahoo may be taken.
All other migratory fish shall be returned to the sea alive unless it is to be used immediately.
No grouper or rockfish weighing less than three pounds may be taken.
No spear fishing within 200 yards of any island in the Bahamas.
It is illegal to use any type of underwater air supply for spear fishing or collecting of any marine life.
This includes scuba gear as well as air compressors.
Spear fishing is restricted to free divers only and only with the use of a Hawaiian sling.
It is illegal to take coral, tropical fish or sea fans.
It is illegal for a non-Bahamian to use any type of fishing net, except a cast net.
It is illegal for a non-Bahamian to use fish traps or to sell marine products of any type.
Become familiar with the Bahamas National Underwater Parks as nothing may be taken from these areas.
Not sure, check with the Bahamian Government for fishing and diving regulations for more details.
