Vietnam’s coastal waters feature high bio-diversity and rich fishery resources. The selected study site, Nha Phu Lagoon is characterized by massive degradation of coastal fishery resources. As a result rural livelihoods in coastal communities are threatened. Since households in these communities not only depend on coastal resources but also have various other forms of income outside the fishery...

The relative roles of density dependence and life history evolution in contributing to rapid fisheries-induced trait changes remain debated. In the 1930s, northeast Arctic cod (Gadus morhua), currently the world's largest cod stock, experienced a shift from a traditional spawning-ground fishery to an industrial trawl fishery with elevated exploitation in the stock's feeding grounds. Since then,...

The oceanographic conditions in the north Pacific have shifted to a colder period, Pacific sardine (Sardinops sagax) biomass has declined precipitously in the California Current, the international sardine fishery is collapsing, and mackerel (Trachurus symmetricus and Scomber japonicus) are thriving. This situation occurred in the mid-1900s, but indices of current oceanographic conditions and th...

Abstract Bottom trawlers are engaged in multi-species fisheries and fish for profit. In quota-regulated fisheries, intra- inter-temporal substitutions of fishing effort is regarded as a key mechanisms that influences the profitability portfolio. The feeding spawning migration patterns available species portfolio alter bio-economic conditions different areas. addition, spatial heterogeneity amon...
