By only awarding use rights to local fishers, the
extractive reserve will limit the number of fishers, but the
reduced number may still represent a very large fishing
effort for the size of the Lagoon and its stocks. One way to
solve this problem is by further limiting the number of
fishers through a licensing system specific to the SLER. In
the proposed SLER licensing system any fisher must buy a
SLER fishing license to fish in the Lagoon. That is, holding
a right of use is necessary but not sufficient to permit
someone to fish in the Lagoon; local fishers with use rights
must still buy a license to legally fish in the Lagoon, but
under their use rights designation they will be guaranteed a
license (provided they pay for it). License prices and
purchase eligibility criteria can restrict the number of
fishers using the Lagoon, and license prices can fluctuate
annually according to resource conditions and environmental
and market uncertainties.
