Management Procedure

From EverybodyWiki Bios & Wiki




The term management procedure (MP[1]), when used in the context of fisheries management, refers to a defined method by which management measures are recommended. The MP is agreed upon prior to the management recommendation being required, in this way ensuring a transparent decision making process. Each MP is designed specifically for the fishery being managed, tailored to make use of the available data and to provide recommendations that are required by managers. A feature of the MP design process is that it attempts to ensure that the behavior of the MP are understood before it is implemented[2]. This typically involves computer simulation of its likely performance, allowing it to be evaluated by decision makers prior to adoption.

Genesis

Although similar ideas already existed in other fisheries[3], MPs in their current form were first developed by the International Whaling Commission (IWC)[4], beginning in the 1970's. Simulation testing was seen as a central part of the development process and became a defining feature of an MP. Parallel developments by CSIRO similarly advocated a simulation-based approach for the selection of what were termed, Management Strategies (MS). The simulation testing and evaluation of a MS was referred to as Management Strategy Evaluation (MSE)[5][6]. Although this process was implicit in MP design from the outset, this terminology has since been transferred and the evaluation used for selection of an MP has become known as Management Procedure Evaluation (MPE)[7].

Definition

A management "procedure" (MP) is a form of management "strategy" (MS), with the latter term able to encompass a wider range of methods by which management measures can be recommended. The terms MP and MS both refer to a decision making process, but an MP always contains the following components:

  1. Observed data;
  2. Estimation of a status indicator from the data;
  3. Harvest control rule (HCR) that converts the status indicator into a management recommendation.

The HCR allows an MP to respond to current conditions: so-called feedback control, and it is this feature in particular that distinguishes MPs as a specific and well-defined type of MS.
