Example text

Friedman et al. (2008a) present a simple approach for managers to assess the health of sea cucumber fisheries and recommendations for management actions and regulations in cases where stocks are either depleted or still healthy. It is a quick “startup” guide to decision-making and introduces the key concepts for implementing many of the common tools for managing sea cucumber fisheries. This paper provides a more comprehensive appraisal of the full range of tools available in the manager’s toolbox.

For export controls of “premium” species groups, shipments will be made and checked in 10 kilogram packages of beche-de-mer. Each package must only include beche-de-mer from a single “species group” and be labelled so as to be easily identified for inspections by the checking authority (for weight and counts). 0 150 Sandfish Golden sandfish Max. number per 10 kg package The 10 kilogram packages allow agents to include product with a small weight variation around the specifications for individual dried sea cucumbers, as long as the 10 kilogram package as a whole complies with the maximum number of sea cucumbers allowed.

In the long term, this objective aligns with a key purpose of the ecosystem approach to fisheries (EAF); to ensure that future generations have access to the full benefit of today’s fisheries (FAO, 2003). Managers should also set an objective to regulate fishing in order to prevent the need to close the fishery by moratoria (or “bans”) because stocks have been overexploited. Other social interests should be addressed, such as those of tourist operators, naturalists, conservation groups and the general public.
