This paper reviews the conceptual background and application of technical reference points in fishery management. Despite considerable investment in stock assessment methodology and expertise, fisheries worldwide are overexploited. This appears to be due to a mismatch between the precision of assessment and the precision of management. Two types of reference points are recognized: target reference points (TRPs) and limit reference points (LRPs). The use of MSY as a target reference point is considered in the light of past performance of fishery management, and it is suggested that MSY and other reference points formerly used as targets, may be more appropriately applied as LRPs. The recent trend towards the quantification of uncertainty and estimation of risk in the provision of advice is considered to be good, but the cost and availability of information and expertise required may preclude the use of these techniques for many small or low value stocks and for most stocks in developing countries. The recent trend towards inclusion of ecosystem concepts in setting fishery management objectives is also seen as good, and overdue. Although still in their formative stages, ecosystem concepts can still provide LRPs. Effective management will require a set of rules comprising both TRPs and LRPs. In most national and international fishery management situations, the current institutional structure will probably require some modification in order to successfully apply these sets of rules. Fisheries management organizations will continue to assess and manage fisheries routinely, but management may need to develop an independent review which comes into play when resource production limits are approached. The action to be taken at such limits should be discussed and agreed in advance.

The paper briefly summarizes the resent development and use of reference points for fisheries management and how they are currrently being used to contribute to precautionary fisheries management. A short review of reference points of actual or potential value will mainly look at those that could be of particular use for developing countries' fisheries and shellfish resources, or oceanic resources such as tuna, where lack of data on age structure and recruitment make application of some of the conventional appraoches used in north-boreal shelf fisheries uncertain. One suggestion that will be made is to consider how multiple reference points might be used based on different criteria.

Two informal Working Groups worked through the document presented as an annex to this report, making a paragraph by paragraph commentary and critique, respectively from the perspective of the fisheries managers, and from that of the technical staff responsible for implementing management guideliens. A new structure was proposed for the document, as well as a list of new topics to be addressed, and a strategy for tackling this task.

Fisheries Economics has always been an interdisciplinary field of study with economic analysis based on stock population dynamics, but many published works have focused mainly on theoretical economic issues without much focus on biological details. For the most part, age structured models have been ignored. Bioeconomics of Fisheries Management is a valuable reference text that presents the economic aspects of fisheries management in a broad bioeconomic framework. The book is broken into two parts. Part I covers the traditional areas of fisheries economics, covering topics such as open access, optimal and managed fisheries utilization that is analyzed through a traditional one stock/one fleet model. It also presents the basic results in terms of an age structured model. Part II covers material related to more recent work on bioeconomic models when more rigorous biological components became more prevalent, and views fisheries management with an ecosystems-based approach. Accompanying the book is a user-friendly CD with exercises and examples that aids the reader in applying theoretical principles of population dynamics and fisheries management and regulation. Bioeconomics of Fisheries Management will be a valuable text for researchers, fisheries economists, professionals, and students alike.
