Douglas Bay Marine Nature Reserve

4.6 km2 MNR on the east coast adjoining Douglas, the island's largest town and port. Protected habitats include rocky reefs, kelp forests and maerl beds. Under the Manx Marine Nature Reserves Byelaws 2018, taking scallops/queen scallops by diving (including while wearing a mask, visor or goggles) is prohibited here (byelaw 10), and byelaw 8 species/habitats are protected. Spiny lobster may be taken here (named exception in byelaw 8(k)). Spearfishing is constrained by these conservation byelaws plus island-wide rules (no salmon/sea-trout retention, minimum landing sizes, bass rod-and-line only).
