the dolphins in the rio coastal areas
have been threatened by overfishing
-
by way
of being caught in fishing equipment and by overexploitation
of their food sources
-
frequent boat passage and environmental degradation around
the metropolis.
as such, though conservation efforts are
underway, dolphin sightings are an increasingly rare and
valuable treat. reporting these sightings through the
cagarras islands website can help
authorities learn more about dolphin habits and formulate
ways to better protect them.
