Trawlers could damage MPAs

skateThe life history characteristics of  bottom feeding fish make them particularly vulnerable to fishing mortality.

This was highlighted again in a recent study into the impact on elasmobranchs  which found that Marine Protected Areas (MPAs) are only likely to be effective only if commercial fishing effort is kept within a level which is consistent with the size and purpose of a MPA.

Quite simply put – excessive trawling / dredging will defeat the purpose of setting up an MPA aimed at regenerating the stocks of any bottom feeding fish.

The study used the example of the Celtic Sea to model elasmobranch biomass – it may be downloaded here.
