According to This Is Cornwall, groups representing water users argue that marine protection plans "would have severe knock-on effects on those who rely on the south west's coastline for employment and leisure".
Alana Murphy of the Royal Yachting Association said: "A lot of the small inshore areas proposed as conservation zones coincide with estuaries and bays that are used by sailors for mooring, or for laying buoys for racing. We are concerned we could lose important sailing areas."
Companies involved in offshore renewable energy have voiced their concerns on the impact of marine reserved on their development, while the National Federation of Fishermen's Organisations added that the scale of proposed fishing reserves was too great, and could potentially push commercial fishermen "to other areas which will then get overfished".
As previously reported on Afloat.ie, the UK's Wildlife Trusts have expressed dismay that plans to establish Marine Conservation Zones in the Irish Sea and elsewhere have been shelved till at least next year after pressure from fishermen, boaters and other groups.
