متن کاملSmall-Scale Spatial Variation in Population Dynamics and Fishermen Response in a Coastal Marine Fishery
A major challenge for small-scale fisheries management is high spatial variability in the demography and life history characteristics of target species. Implementation of local management actions that can reduce overfishing and maximize yields requires quantifying ecological heterogeneity at small spatial scales and is therefore limited by available resources and data. Collaborative fisheries r...
متن کاملOccurrence of Mislabelling in Prepared Fishery Products in Southern Italy
Fish authentication is a major concern not only for the prevention of commercial fraud, but also for the assessment of safety risks deriving from the undeclared introduction of potentially dangerous toxic or allergenic substances or environmentally damaging fish where endangered species are involved. Moreover, food authentication might affect the diet of certain groups of consumers, such as fol...
متن کاملThe impact of trawl fishery on the epifauna of the southern North Sea
Qualitative historical benthos data (1902–1912) were compared with recent data (1986) to find long-term trends in epifauna species composition in the southern North Sea that may be attributed to fishery-induced changes. In general, the frequency of occurrence of bivalve species declined, whereas scavenger and predator species (crustaceans, gastropods, and sea stars) were observed more frequentl...
