The Sacca di Goro is one of the top Italian sites for clams farming with over
1/3 of the lagoon surface exploited, an average annual production actually
around 8,000 tons and peaks up to 15,000 tons. In the last 20 years clams
growth and survival has been seriously threatened by the development of large
macroalgal beds (Ulva spp.) and the occurrence of summer dystrophic
events. However farming activity itself has probably caused environmental
disturbance as molluscs respiration rates deplete large amounts of oxygen and
biodeposition enhances benthic microbial activity and nutrient recycling.
We discuss results from a number of experiments focused on the comparison of
benthic metabolism and nutrients recycling in farmed and control areas of the
Sacca di Goro and on the interactions between filter feeders and macroalgae.
