I'm a native of Grand Bahama and I too found the regs confusing, but as of January, still legal
to take 6. See letter below dated January of this year:
I refer to your e-mail of 26th January, 2013 on the above subject matter.
Please be advised that all foreign owned vessels engaging in any fishing
in The Bahamas
must first obtain a sportfishing permit
from a Bahamian border official at a Bahamian port of entry.
Your allowable quota for conch is six (6) conch per vessel at any one time. You may export the allowable quota on your vessel.
All harvested conch must have a well formed flaring lip indicating adult sizes. The undersized conch must not be harvested in The Bahamas
