remained relatively stable over the past two decades while fish production through aquaculture has progressivly increased. The Indian fisheries sector has come a long way since independence (Figure 1) and has contributed immensely to the food basket of the country, with annual production levels of over six million tonnes of fish and shellfish from capture fisheries and aquaculture. India is the...

The paper reviews the main findings of rocky shore and subtidal nearshore experimental marine ecology (EME) in cold and temperate marine ecosystems during the past four decades. It analyzes the role of EME in coastal management and conservation. The historical development of strategies for managing single or multispecies fisheries are reviewed. The published results show over-exploitation and d...

This paper is an attempt to synthesis the Danish experiences of devolved decision-making in fisheries, giving particular attention to the role of fishermen’s organisations in fisheries governance. The analysis are focuses on how user participation are institutionalized as comanagement between administrators and user groups. The paper discuss the possibilities and constraints for devolved an reg...

Regional councils manage United States fisheries. Fishermen can participate in fisheries managed by multiple councils, and effort controls in one region could lead to effort leakage into another. Theoretical modeling demonstrates that positive, negative, and no leakage are possible. Using difference-in-differences, we test for leakage across regional boundaries for a catch share program in New ...

Background: Kelp forests are highly productive ecosystem engineers of rocky cold-water marine coastlines, providing shelter, habitat and food for a variety of associated organisms. Several factors have been related with an observed trend of kelp deforestation in some regions of the globe. The effect of this trend on fisheries has been poorly studied. The European directives addressing the conse...

Although fisheries production and seafood trade are global in scope, with billions of dollars in exports, the rebuilding of collapsed fisheries often focus on national fisheries policy and management measures, with little attention to global supply chains and international consumer markets. Even with two moratoria and two decades of policy changes since the Northern Gulf cod fisheries collapsed...

Biological diversity is known to play an important role in generating and maintaining ecosystem productivity and other functions, and has consequently become a central focus of many efforts to preserve ecosystem services. Theoretical parallels suggest the diversity of fishing fleets may have a similarly important role in determining the productivity and ecological impacts of fisheries, but this...
