Abstract
A crucial aspect in climate change is to understand how an ecosystem
will adapt under different environmental conditions and how it will
influence the ecological resources and the connected human activities.
In this study, a numerical model reproduces the growth dynamics,
dispersion and settlement of clam's larvae in the Venice lagoon. On the
basis of the last IPCC scenarios for the years 2050 and 2100, the model
simulates the changes in larval settlement, showing how the geographical
distribution and, consequently, the nursery area changes over time.
Our results indicate that climate change will modify, not only the
timing of the settlements (from springsummer to winter autumn) and the
spatial distribution of nursery areas (from central to southern lagoon),
but also the absolute quantity of settled larvae in the lagoon. This can
strongly affect aquaculture in terms of availability of seed and farming
practice. Given that these changes are due to the variations in
temperature and circulation, similar processes are likely to happen in
other transitional environments all over the world affecting the global
aquaculture resources. In this regard, the tool we developed could
support local policy-makers in the knowledge-based planning and
sustainable management of clam aquaculture in vulnerable environments.
