Quota Markets and Risk Pools in Multispecies Catch Share Systems

Most catch share systems allow transfers of catch quotas between fishermen.  This allows quota to move to fishermen who can generate more profit from catch. In multispecies catch share systems, quota transferability plays a particularly important role since it is often difficult to control the species composition of catch, and fishermen must often acquire quota to cover unexpected catch.  Quota prices in these fisheries can play an important role in ensuring efficient utilization of the resource. For species that have the potential to constrain harvest of a jointly caught target stock, quota prices should typically increase reducing the profitability of catching that species or potentially creating a penalty for doing so. This should incentivize fishers to change targeting behavior to reduce relative catch rates of “weak” fish stocks for which TACs are relatively more constraining and allow fuller utilization of TACs of species that are more abundant. However, there has been relatively little study of quota markets and it is not clear that quota markets work efficiently and generate prices that reveal the true value of quota, particularly for species taken primarily as incidental catch. I discuss here the function of quota markets in the British Columbia and US Pacific groundfish fisheries. In both of these fisheries fishermen rely on pricing strategies and non-market mechanisms to redistribute quota that do not appear to generate “efficient” quota prices though they may still be effective at moving quota to those who need it.

Global Seafood Markets in 2030: Dominated by Aquaculture, with Wild Fish as Niche Market Products?

Aquaculture has been the world’s fastest growing food production technology in the past three decades, and has during this period profoundly changed the seafood market. There are a number of drivers in this process on the production as well as the market side. Understanding these drivers is important to understand why aquaculture production is set to continue to grow and further transform the seafood market. As aquaculture is a new way of using the environment, the growth in aquaculture production has also raised a number of environmental challenges. These challenges can all be addressed, but it largely depends on the governance system whether they are. Some countries, like the USA, is so risk averse that they do not allow a domestic industry to grow, but rather import from other countries.

A metabolic constraint on marine habitat and its climatic changes
Curtis Deutsch, School of Oceanography

The warming of the world’s oceans and the consequent loss of dissolved O2 are expected to have profound impacts on marine ecosystems, but a quantitative framework for predicting their synergistic effects on species habitat is lacking.  Here we integrate laboratory, demographic, and climate data to map an index of sustained metabolic scope – the ratio of O2 supply to resting metabolic demand – across the geographic range of several diverse species.  Despite large differences in thermal and hypoxic tolerances between species, their contemporary habitats are all bounded at the equatorward edge by a similar metabolic index corresponding to an active metabolic rate roughly twice that at rest.  This ratio is within the range of values estimated for terrestrial organisms, and implies that aerobic metabolism is a fundamental constraint on marine habitat. Based on future climate simulations, warming and deoxygenation together will reduce the metabolic index of the upper ocean by ~20% globally and by ~50% in northern high latitude regions with productive fisheries.  Loss of viable habitat for individual species is predicted to be of similar size.  In contrast to many terrestrial species, these climatic limits and their largest projected changes operate at the warm rather than cold edge of species geographic ranges.

Multiple margins of fishing behavior: Implications for predicting the biological and economic effects of a policy change.

Abstract
The history of fisheries management is full of instances in which regulators have failed to anticipate the behavioral response of fishermen to a policy intervention. Such surprises can largely be ascribed to a poor understanding of the multiple margins across which fishermen can act. Much economic analysis oversimplifies the fishing production process by collapsing margins of fishing behavior—such as the use of fishing gear over space and time—into aggregated and general production and cost functions. Using numerical simulations together with an empirical investigation of the Bering Sea groundfish fishery, our research demonstrates that aggregated models of fishing behavior provide policy makers with inadequate, and possibly misleading, information on which to base predictions regarding the extent and nature of a fishing industry’s response to a policy change. Our research suggests that accurate assessment of the effects of a policy intervention requires a description of the fishing production process that is sufficiently “deep” so as to be invariant to changes in management institutions.

Just tell us what to do

Abstract
“Just tell us what to do,” said a policy-maker seeking scientific advise on how to manage  a protected area in Mozambique. Although a protected area, over 340 thousand people rely on its   coastal and marine ecosystems to support thousands of artisanal fishers, protect communities from   coastal hazards, and retain sediments from nearshore waters. In Africa and elsewhere, governments,   multi-lateral investment banks and corporations are asking increasingly for these types of information   about how nature benefits people. Recent advancements in our understanding of relationships   between ecological processes, economics and human well-being are beginning to provide some of the   answers. Yet, more empirical evidence is needed to test whether ecosystem service science delivers   a useful framework and analytical approaches for informing conservation, resource management and   development decisions. I will talk about several projects my colleagues and I at the Natural Capital   Project are engaged in to tackle these issues, including marine spatial planning in Belize and natural   defenses from coastal hazards in the United States. I will highlight opportunities for advancing the   science and uptake of nature’s benefits to people in decision-making.
