We have come a long way since the first days of Project Permit.
Thanks to this program permit have received improved
protections in Florida. The Florida Keys is now a Special Permit
Zone, where the spawning season is closed to recreational
harvest, recreational harvest limits are now reasonable, and
there is no commercial fishing is allowed.
One of the main goals of Project Permit is to determine whether
the spatial scale of conservation is appropriate for management
of the permit fishery at hand. For example, in Florida, is the
Special Permit Zone appropriate for protecting the flats fishery in
the Keys? Is the Sian Ka’an Biosphere Reserve in Mexico large
enough to protect its famous permit population? Where should
habitat conservation efforts be targeted in Belize?
Since 2010 BTT has been working with fishing guides and
anglers in a tag-recapture approach to estimate the movement of
permit. In Florida more than 1,000 permit have been tagged, but
only 16 have been reported recaptured. The recaptures show
two modes of movement: first, most (13) recaptures occurred
within the same region as tagging. Interestingly a second
observation found that three permit were recaptured more than
20 miles from the tagging location, suggesting permit do indeed
undergo long-distance movements. Were these movements
associated with spawning or just normal movements? The jury is
still out on whether the Special Permit Zone is large enough to
protect the Keys flats fishery.
In Mexico, more than 300 permit have been tagged and six have
been recaptured, all close to the tagging location. But the
studied fishery occurs in a relatively small portion of Ascension
Bay, so the question remains—are permit also traveling longer
distances and just not being caught? Work is ongoing to figure
this out by educating fishermen who fish outside of the protected
zone to report any tagged permit they recapture.
