Number of Dredges

Summary

In some scallop dredge fisheries the number of dredges used is regulated to ensure fishing effort remains within manageable limits.

Size selectivity

This is more to maintain about managing  fishing effort rather than size or species selection. However its effectiveness can be improved by combining it with other selective measures or regulations suitable for dredge fisheries.
