Última Potential economic impacts of achieving good environmental status in Black Sea fisheries Ecology and Society Goulding, Ian C; Megapesca Lda, Portugal; ian@megapesca.com; Stobberup, Kim A; Megapesca Lda, Portugal; megapesca@mail.telepac.pt. The Marine Strategy Framework Directive (MSFD) mandates that European Union (EU) member states achieve Good Environmental Status (GEnS) based on an ecosystem-based approach to management. For commercial fisheries, the primary target under the MSFD is one of maximum sustainable yield. Of Black Sea riparian nations, only Romania and Bulgaria are EU member states. Focusing at the supranational level, we review institutions and instruments relevant to management of the Black Sea. The economic values of current fish catches are assessed, and the results of a recent analytical assessment of fish stocks are used to estimate potential future values based on maximum sustainable yields. In the Black Sea region, despite long-standing attempts to improve fisheries...

Ano: 2014 Emergence of a new predator in the North Sea: evaluation of potential trophic impacts focused on hake, saithe, and Norway pout ArchiMer Cormon, Xochitl; Kempf, Alexander; Vermard, Youen; Vinther, Morten; Marchal, Paul. During the last 15 years, northern European hake (Merluccius merluccius) has increased in abundance, and its spatial distribution has expanded in the North Sea region in correlation with temperature. In a context of global warming, this spatial shift could impact local trophic interactions: direct impacts may affect forage fish through modified predator–prey interactions, and indirect impacts may materialize through competition with other resident predators. For instance, North Sea saithe (Pollachius virens) spatial overlap with hake has increased while saithe spawning-stock biomass has decreased recently notwithstanding a sustainable exploitation. In this context, we investigated the range of potential impacts resulting from most recent hake emergence in...

In Europe, implementation of sustainable fisheries management has been reinforced in the latest common fisheries policy, and presently marine fish stocks are mostly managed through assessment of their exploitation and ecological status compared to reference points such as Maximum Sustainable Yield (MSY). However, MSY and its associated fishing mortality rate FMSY are sensitive to both stock characteristics and environment conditions. In parallel, climate change impacts are increasingly affecting fish stocks directly and indirectly but might also change the exploitation reference points and the associated level of catch. Here we explored the variability of MSY reference points under climate change by using a multi-species model applied to the Eastern...

Ano: 2020 URL: https://archimer.ifremer.fr/doc/00657/76939/78140.pdf An Economic Analysis to Sustainable Fisheries Management OceanDocs Lokina, R.B.. The coastal zone is a dynamic area surrounding the interface between land and sea. The coastal area and its resources offer great benefits and opportunities for human use. Most coastal activities in Tanzania rely on the natural resources that the coast offers (fishing, forestry, agriculture, tourism, mining, salt production mariculture etc). Therefore the condition of the coastal ecosystem and social well being are closely linked. The challenge is to maintain and improve the resources base on which those activities are dependent, while developing new economic opportunities in a way that benefits the people of the coast and the nation as a whole. A major constraint is the inadequate institution and legal framework for coastal management. Economics is about...
