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...
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...
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...
There is growing realization of the potential for games and experiments as powerful tools for education, outreach and research in many fields of science. Particularly in fisheries management we face a growing demand for stakeholder involvement, which requires new ways in reaching informed decision making. Games and experiments can be...
Fishery scientists distinguish between recruitment overfishing (i.e. suboptimally low reproduction because the spawning stock is fished down) and growth overfishing (i.e. catching fish at an inefficiently young age). We use an age-structured bio-economic model to study how important the (endogenous) recruitment is compared to the growth of individual fish under...
