Scientists question fisheries health test

Summary:
A measure widely advocated as a means of assessing the health of marine ecosystems is an ineffective guide to trends in biodiversity, and more direct monitoring is needed, a new study has found.

Global fisheries are at a crucial turning point, with high fishing pressure being offset in some regions by rebuilding efforts.

The findings – published this week in Nature – followed an examination of whether changes in fishery catches reflect changes in the structure of marine food webs, and therefore are a suitable guide to assess the impacts of fishing on marine ecosystem health.
