Abstract
In the 1990s, the central Tyrrhenian Sea was regarded as a transit region for
fin whales’ (Balaenoptera physalus) summer migration. In recent years, a much
higher presence of fin whales during the entire summer season was reported in
the region. The hypothesis that the central Tyrrhenian Sea may have become a
summer feeding ground was tested gathering data from summer presence of whales
in the region (40–42.5°N; 9–13°E) and investigating whether it might be related
to sea surface temperature and chlorophyll-a concentration, considered as
proxies of food availability. Results showed that whales always aggregate in
the more productive portions of the investigated area; the general productivity
of the area, however, did not directly influence the frequency of occurrence of
whales. We concluded that the complex dynamics of the balance between feeding
activities and avoiding pressures may have led fin whales to use the region as
an opportunistic
feeding ground.
