Management of evolving fish stocks
Canadian Journal of Fisheries and Aquatic Sciences, 1998Mortality caused by harvesting can select for life history changes in the harvested stock. Should this possibility be taken into account in the management of renewable resources? I compare the performance of different harvest strategies when evolutionary change is accounted for with the help of an age-structured population dynamics model.

Methods to Describe Fish Stocks
1993The description of the genetic diversity of species is a prerequisite step for both basic (understanding of mechanisms involved in the adaptation and evolution of species) and applied (management of the genetic resources of species) purposes. This description includes two major phases.

Physics World, 2000
Overfishing is a worldwide problem and many of the world's fish stocks are severely depleted. A fundamental question in light of the current state of affairs is whether it is at all possible to manage fishing grounds so that they remain sustainable? If so, how can the sustainability of fish stocks be best achieved and ensured?

Sharing a Migrating Fish Stock
Marine Resource Economics, 2013Abstract The sharing of a migrating fish stock between two players is considered. Data on the Northeast Atlantic mackerel are used to model the fishery. A growth function is estimated, and random fluctuations in growth and recruitment are used to simulate the fishery.

Juridical status of fish stocks.
2010AbstractThis chapter discusses the juridical classification of fish stocks, particularly straddling fish stocks and highly migratory fish stocks, under United Nations Convention on the Law of the Sea (LOSC) and UN Fish Stocks Agreement (UNFSA). The political and legal division of the oceans into various zones of jurisdiction and resulting maritime ...

Spatial-temporal fish stock assessment.
2009This thesis explores an alternative method of assessing the status of commercially exploited fish stocks. Aggregate numerical least-squares regression methods are most often used to estimate fin fish population numbers by age of fish within the stock.
