We describe the process used in the fisheries management system of the Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR) to minimise seabird bycatch, and the risk-assessment methodology developed to assist this. We examine the progress of several Regional Fishery Management Organisations in taking steps to address seabird bycatch. CCAMLR has the most advanced system ...

Levels of fishing effort are defined as being excessive where they result in depletion of commercially valuable stocks and so threaten sustainable harvests. In many parts of Southeast Asia, this threat has been realized by the rapid expansion of commercial fisheries and the consequent increase in fishing effort. Southeast Asian fisheries are described as having a dualistic structure with distin...

1. Fisheries bycatch has been implicated in declines of many long-lived marine vertebrate populations, but bycatch impacts on these populations vary according to spatio-temporal overlap in fisheries operations and critical ontogenetic habitat, as well as to characteristics of fishing gear. 2. To provide a framework for comparing the relative impacts of different fisheries on populations of logg...

Fisheries management requires making complex decisions that account for multiple objectives involving many participants in an inherently variable environment. The form and function of management remains a major strategic issue as we approach the next century. Management approaches for the future need to focus on integrating biological, economic, social and political considerations of fisheries ...

In recent years the collection of tropical marine organisms for the aquarium trade has become perceived as an activity with an unsustainable history as well as obvious potential for rehabilitation through resource-based fisheries management and consumer-oriented product certification. In the case of Puerto Rico, collection of ornamentals has existed for decades, though unregulated due to a weak...

This section is an effort to identify the efforts of PICES member countries in moving toward adoption of an EBM approach for fisheries and other sectors. Member countries were asked to confirm their commitments to, or incorporation of ecosystem-based management (EBM) actions or principles, into current fisheries and ocean management. As reported below, there is a wide range of effort in this re...

Exploitation of fish and shellfish stocks by the European Union fishing fleet is managed under the Common Fisheries Policy (CFP), which aims to ensure that fishing and aquaculture are environmentally, economically and socially sustainable and that they provide a source of healthy food for E.U. citizens. A notable feature of the CFP is its legally enshrined requirement for sound scientific advic...

Traditional fisheries management theory supports aggressive exploitation of old and large fish to maximize a stock’s biomass production and yield. Here we present an age-structured fish population model with multidimensional density-dependence to test the hypotheses that protection of large, fecund individuals is beneficial for the population and selected fisheries variables and that effects of...

The Atlantic sea scallop fisheries in the U.S. and Canadian o≠shore waters provide a natural experiment in fisheries management regimes. Starting in 1986, in side by side areas of George’s Bank, Canada adopted a rights-based approach while the U.S. continued with effort controls. Analysis of their experiences shows that the resource has been better maintained in Canada with lower fishing e≠ort,...
