Razor clams Ensis minor (Chenu, 1843) and Solen marginatus (Pulteney,
1799) represented in the past an important source for clam fi shery in Italy. Strong
oscillations observed in recruitment as well as in growth rate are currently limiting
the importance of E. minor, whereas S. marginatus (less valuable) seems to be the
most important part in catches, as suggested by the result of surveys carried out in
North-Eastern Italy and by the information collected either from the Maritime District
Authorities where this activity is exerted and from market operators. Hydraulic dredge
exploitation faces a decline but on the other hand the emerging professional diving
fi shery suggests serious problems in managing the resources.
