The complexity of small-scale fisheries makes it difficult to predict the allocation of fishing effort among alternative target species in mixed fisheries, resulting in limitation for fisheries management. One reason for the difficulty is that fishing effort has been assumed as an aggregate of different components, without consideration of fishers’ decisions. In this paper, we use discrete choi...

Clarias gariepinus is a threatened highly prized species used for some elite ceremonies by the local communities. Artisanal fishers take advantage of this species annual breeding migration from the lower Cross River to the floodplain lakes in Mid-Cross River during the rainy season, and some migrant stocks are not able to spawn. Since there is a lack of information on this species population dy...

To help manage the fluctuations inherent in fish populations scientists have argued for both an ecosystem approach to management and the greater use of marine reserves. Support for reserves includes empirical evidence that they can raise the spawning biomass and mean size of exploited populations, increase the abundance of species and, relative to reference sites, raise population density, biom...

The fisheries crisis of the last decades and the overexploitation of a great number of stocks (FAO 1995) have been due mainly to the inadequacy of scientific knowledge, uncertainties in assessments and/or failures of the management systems. These problems are critical when the management of coastal ecosystems and artisanal fisheries is involved. These systems possess great complexity due to the...

In Japan, fisheries’ product has decreased since the 1980s, and government amended fisheries law in 2020 to shift managed fisheries. However, awareness of seafood sustainability is still low. This study identifies reason for low states necessary actions increase sustainable consumption. The proactive stakeholders supply were surveyed determine current status sales. Marine Stewardship Council-ce...
