Bioeconomic modeling of an age-structured population typically assumes the value of a fish increases with size; the fish increase in weight as they age, and harvesters may receive an increase in the price per weight. When size selectivity is possible, traditional policy such as individual quotas may still result in...
Economists and biologists have recognized that spatial and temporal area-closures may provide an effective means of managing the impact that fisheries have on one another and upon threatened species. To date, however, little work has been done to estimate the economic impact of protected areas on commercial fishing. One significant...
The Alaska non-pollock multi-species catcher processor trawl fishery, referred to as the Amendment 80 fishery since 2008, is an endlessly fascinating subject from the perspective of an economist. A diverse group of companies and vessels, emphasizing different species mixes from a multi-species ecosystem, targets fish across the Eastern Bering Sea,...
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...
We describe the dynamics by which competing harvesters selectively target prime market-sized fish, without internalizing the externality of increasing targeting costs, as the abundance of prime fish decreases. Due to the increasing targeting costs for prime size, harvesters continually target the next-most-desirable size fish, gradually fishing down the size structure...
Multispecies fisheries add additional complexity for rights-based management implementation. Imperfectly selective fishing gear may make it difficult for fishermen to match their catch composition with the portfolio of total allowable catches chosen by management. If fishermen can perfectly target their catch, the problem of matching catches with quota allocations declines...
This talk will introduce the special session on the Economics of Bycatch. It will provide an overview of the session. It will then discuss in general terms a variety of incentive-based approaches to managing bycatch that give vessels greater flexibility to devise cost-effective solutions of their own making. These include...
Metabolomics is a comprehensive analysis of small molecules, or metabolites, in a system. Metabolomics is a hypothesis-generating experiment and offers an unbiased analysis of cell metabolism that can aid in the understanding of fundamental biological processes. Metabolomics is widely and broadly applicable in the biological sciences and has been used...
This document provides a summary of a Special Session held at the IIFET 2016 Scotland conference in July 2016. The registration number and title of the special session were 5313: Analyzing behavioral responses to regulation – what can be learned for management? The session was organized by Florian K. Diekert,...
