Abstract
    In Peru over the last two decades, the Peruvian bay scallop has become one of the most important mollusc resources in terms of export with volumes greatly fluctuating since the onset of the export business in the early 1980s. In this study, scallop landings trends, export volumes and stock biomass are analysed for the entire Peruvian coastline and the role of El Niño and La Niña events for the productivity of the principal scallop banks is assessed. The study reveals that scallop landings and stock biomasses are well correlated for the principal banks of Independencia Bay, Lobos de Tierra Island and Sechura Bay. The scallop harvest from these banks was analysed taking into consideration the exploitation strategies used during the El Niño events of 1982/83 and 1997/98 and the possible impact of farming activities (“seed collection and scallop fattening”). Changes in the dynamics of the natural scallop banks in the Bay of Independencia and Lobos de Tierra Island during periods of El Niño and La Niña off the Peruvian coast are presented and discussed. Finally, considerations for the elaboration of a management plan for scallop stocks under conditions of climate variability and great spatio-temporal variations in local abundances are presented.
