Resumo(s)
The Lagoa de Santo Cristo in São Jorge is the
only place in the Azores where the venerid bivalve Tapes decussatus (Linnaeus, 1758) forms a well established and stable population. This is in itself already a remarkable situation, for the geographically nearest populations of this species live, as far as we know, along the Atlantic coasts of
Portugal and Morocco. Thus the Azorean stock is separated from its neighbors by an oceanic gap of more than 1500Km. Another important characteristic of the Azorean Tapes population is the constant human pressure under which it survives. Indeed, Tapes is considered as a popular food item
for human consumption and it has therefore been intensively fished in the Lagoa de Santo Cristo, even though in the last years several measures have been taken to regulate the Tapes fisheries.
