    Default Kelp Harvesting

    A firm call Bio Polymers wants to start mechanical kelp dredging at, at least 12 sites round the Scottish west coast and islands, they say that this environmentally sustainable, at 30,000 tons per year, so what will this do to inshore feeding grounds particularly for young sea trout, so much for the wild fish protection bill, easker1

    It's a very old practice, the problem might be one of scale. I wonder what they plan to use the kelp for?.
    Jersey Royal potato's got, and in some case still do, their flavour from the dried seaweed used as a fertilizer, I think the Jersey name for it is Vraick. Might be misspelt.

    Oh no it's not ,maybe the clue is in the name of the firm? it was taken by hand years back I did it with a sickle in the 70's this is mechanically dredged kelp, up to 30,000 tons/yr.the old folk took it for fertilizer for all crops it was known as Wrack, but a lot of it was taken from the shore after a gale, not done with Machines, easker1

    It is harvest by machine in many parts of the world, notably in the America's.

    Being done by machine isn’t intrinsically bad. But the ability of machines can lead to a hell of a profit and that’s so tempting in the short term. We love to hate ‘ red tape’ but it can be the difference between optimising a resource and wrecking it.

    Oh well then we should just let them get on with it and count the cost later?,especially to our inshore fish stocks,sea trout feed inshore when the first get to sea,where do juvenile Bass feed? and all the other species?Scotland has tried to introduce a wild fish protection bill but this will snooker that in more ways than one

    That’s certainly not what I implied. You have to accept peeps will follow efficiencies but with that has to be some measure of overall control. It’s what governments/governance is all about surely?

    The point is no one knows conclusively how it will effect the marine environment which is where licencing and monitoring comes in. However, given the Scottish governments record with salmon farming you are probably right to raise concerns. It's the fact that they can state 30,000 tons is sustainable without any independent scientific evidence to support such a claim that raises the biggest concern, it is that and not harvesting of kelp per se that needs addressing.

    They say.....

    ''Our future seaweed harvesting methodology, which has been developed in close co-operation and consultation with heritage and other environmental bodies, as well as with experts linked to Queen’s University Belfast ensures that no harvesting area will be visited too often, that varying and appropriate methods are used for each seaweed species to promote good recovery, and that sensitive fauna regions are avoided altogether''

    But of course we have heard this stuff before.
