- Abstract
The evolution of fishery and land reclamation in Lesina (Italy) and Curonian (Lithuania/Russia) lagoons was analysed as an example of recent trends in European coastal lagoons. Social and political changes were considered, addressing resource exploitation and inherent impacts on ecosystems. In both lagoons, the mismanagement of the fish stock led to the depletion of fish resources and to the decline of commercial fishery. In parallel, vast wetland fringes were reclaimed and turned into intensively managed farmland, with a marked loss of aquatic–terrestrial ecotones. In the last decades, the annual fish yield fell to less than 40 kg ha−1 in the Lesina lagoon, where the fishermen dwindled to 40 units, mostly pensioners rounding off their income. Recently, in the Curonian lagoon, more than 100 small private fishing enterprises were licensed to fish. Overall, the landed catches were difficult to monitor, which resulted in a substantial uncontrolled landing of fish (up to 60% of the fish yield). Under these conditions, the sustainable exploitation of lagoons and their resources can be achieved through an integrated management of watershed and lagoons. The restoration of ecotones, marshes and floodplains and the preservation of semi-natural agricultural ecosystems have to be considered as priorities. Examples of such approach are provided by pilot programs, aiming at the commercial exploitation of the reed belts along the Curonian lagoon fringes. Reed harvesting would increase the acreage of important migration corridors and spawning habitats for fish, also providing an additional income to the local communities.
