The Bohai Sea is one of the most important fisheries resources in China. Fisheries and mariculture are the main industries offering important food security by exploitation of migrating and stationary resources based on the same ecosystem in Bohai Sea. Understanding the potential bioeconomic interactions between fisheries and mariculture will provide the basis for fisheries and mariculture manag...

Mean trophic level (MTL) of landings and primary production required (PPR) by fisheries are increasingly used in the assessment of sustainability in fisheries. However, in their present form, MTL and PPR are prone to misinterpretation. We show that it is important to account for actual catch data, define an appropriate historical and spatial domain, and carefully consider the effects of fisheri...

Sustainably managing ecosystems is challenging, especially for complex systems such as coral reefs. This study develops critical reference points for sustainable management by using a large empirical dataset on the coral reefs of the western Indian Ocean to investigate associations between levels of target fish biomass (as an indicator of fishing intensity) and eight metrics of ecosystem state....

The fisheries sector in sub-Saharan Africa has benefitted from high and increasing amounts of foreign aid for over four decades. In the 1990s when evidence emerged that most stocks were overcapitalized and overfished, the effectiveness of fisheries development aid, particularly those directed at fishing capacity enhancement, came into question. This report examined the relationship between deve...

Many fisheries are potentially very valuable. According to a recent report by the World Bank and the FAO (2008), global fisheries rents could be as high as US$ 40-60 billion annually on a sustainable basis. However, according to the report, due to the “common property problem”, most fisheries of the world are severely overexploited and generate no economic rents. The Lake Victoria Nile perch fi...

The reported annual yield from inland capture fisheries in 2008 was over 10 million tonnes, although real catches are probably considerably higher than this. Inland fisheries are extremely complex, and in many cases poorly understood. The numerous water bodies and small rivers are inhabited by a wide range of species and several types of fisher community with diversified livelihood strategies f...
