In the European Union (EU), marine resource management policies and legislation include not only environmental objectives but also a broad range of explicitly stated economic, social and institutional (ESI) goals, objectives and priorities. Although the environmental objectives often guide scientific assessments, the ESI objectives are often the primary drivers of...
The success of fishery management ultimately depends on the approach of implementation. Past fishery management has relied largely on technical regulations. Examples for such command-and-control measures include detailed gear prescriptions, restrictions on the days-at-sea spent fishing and vessel capacity, and minimum landing sizes. Resource economists have argued in favor of...
To achieve sustainable fisheries, ecosystem-based fisheries management
yields increasing attention. However, so far mainly single-species models
are used to develop management advice, not accounting for species
interaction. In particular many traditional fisheries economic models have
been criticized by biologists, especially if results were gained by rather
simple biomass models. Therefore,...
Ecosystem based fishery management has moved beyond rhetorical statements calling for a more holistic approach to resource management, to implementing decisions on resource use that are compatible with goals of maintaining ecosystem health and resilience. Coupled economic-ecological models are a primary tool for informing these decisions. Recognizing the importance of...
Fishermen are often advised to be more patient and limit catches now, in order to increase stock size and catches in the future. Such scientific advice is usually based on the maximum sustainable yield (MSY) objective. This biological criterion is often consistent with economic interests at low discount rates. The...
There is growing realization of the potential for games and experiments as powerful tools not only for research, but also for education and outreach. Experiments are particularly powerful and useful for fisheries economists because (a) they can vividly illustrate some fundamental concepts and (b) are effective at testing the relative...
Economic drivers of change, such as changes in demand and fishing technology, are as important for the future state of fish stocks as factors influencing ecological processes (Quaas et al. 2016) . Fish and seafood (FaS) are among the most globalized commodities, and markets will continue to globalize in the...
This study compares globally available integrated ecological-economic models with focus on use and implementation in scientific and advisory contexts. The Ecosystem based Approach to (Fisheries) Management (EAM) calls for an understanding and management of fisheries and other uses of the marine environment that explicitly take into account ecological, economic and...
