[Lord Forsyth of Drumlean (Con)]

My Lords, it is a pleasure to move this very modest and uncontroversial amendment, which would place a duty on the Crown Estate, in carrying out its functions under the Bill, to assess the environmental impact and animal welfare standards of salmon farms on the Crown Estate. If an assessment determines that a salmon farm is causing environmental damage or significant animal welfare issues, it must revoke the licence for the farm in question. If assessments of the potential environmental impact and animal welfare standards of applications for salmon farms on the Crown Estate determine that they may cause environmental damage or raise significant animal welfare issues of concern, the Crown Estate must refuse these applications. Who could be against that, except people running salmon farms that do not meet those conditions?

I should begin by declaring an interest. I am a fisherman and my family own one week on the River Tay. I confess that I am absolutely bewitched by the glory of Atlantic salmon, which are now considered an endangered species alongside mountain gorillas and Siberian tigers. This is a really serious issue.

The Crown Estate commissioners on both sides of the border—I regret that the Bill does not cover the commissioners’ activities north of the border because of devolution, but I am sure that if England sets the standard then others will follow—have a responsibility to protect the seabed, which was owned by the Crown and has been vested in the Crown commissioners for centuries. The monarch is not involved, but the commissioners should have a clear duty to protect the environment and nurture the ocean’s wildlife, particularly given the commitment to those ideals of members of the Royal Family, in whose name they act.

I shall concentrate on the impact of farming Atlantic salmon, which has to be licensed by the Crown Estate. There are farming interests that have very high standards, but a wide variation of standards has been applied to salmon farming across the globe. All over the world, salmon farming has resulted in environmental damage to wild fish populations and threatened other species as a result of varying practices.

Salmon are often concentrated in large numbers in open-net cages and flushed with chemicals and antibiotics to combat disease and lice—lice that literally eat the fish alive if not treated. The death rate in the cages is appalling and would never be allowed for conventional farming. Some 20 to 40% of those salmon die and are dumped. Imagine what people would say if they were going past fields of cows or sheep and finding those sorts of casualty levels—there would be an outcry. But of course all this is unseen because it is below the surface of the water.

The list of various toxic chemicals that have been used to tackle lice includes organophosphates, which are highly dangerous, as we were often reminded by a former Member of this House. Other chemicals work by dissolving the bodies of the lice on the salmon, which are crustaceans. That results in the chemicals leaching into the sea and may very well explain why fishermen then start catching lobsters and crabs with half their shells dissolved. I urge anyone listening to this debate to look on YouTube at the horrific condition of salmon in some of these cages as a result of uncontrolled sea life predation. It is a horror movie that is widely available and very easily seen.

The feed that these salmon are given is fishmeal pellets, to which further chemicals are added, including in some cases dioxins and PCBs. These are all controlled, but to present this as a sustainable environmentally-friendly product stretches credibility. Other chemicals are included in the feed in order to change the colour of the flesh. If you are a supermarket, rather like when you want to paint your house, you can get a colour code and choose in which shade of orange or red you would like the fish on your shelves to appear—perhaps, as a result, misleading the customers as to what it is they are buying.

The importance of ensuring effective regulation and best practice hardly needs emphasising. The supply of pellets demands catching gargantuan quantities of small fish. Estimates vary, but those that I have seen are that between 3 and 5 kilograms of anchovies, sardines and other small pelagic fish are needed to produce just 1 kilogram of farmed salmon. That is a ratio, if you are being kind, of 3:1. To describe this as a sustainable business beggars belief. The scale is such that whole fishing communities have lost their livelihoods in west Africa, where the fish are taken by large vessels and turned into fishmeal, creating a lack of employment for local fishermen and a collapse in local economies.

There is also irreversible damage being done to the seabed as fish faeces, chemicals and uneaten food fall through the cages. All that lands on the seabed, creating a disgusting, vile brew on an industrial scale. There are vast numbers of fish. Even in a small tank there will be 20,000 salmon, with up to 90,000 in the larger cages.

Such high concentrations of salmon produce high concentrations of lice. These swarms of lice attach themselves to wild, migrating salmon, with fatal results. Escapees bring diseases to the wild population and whole rivers have been cleaned out of wild fish. Diseases include ISA—infectious salmon anaemia—and bacterial kidney disease. ISA is like AIDS for salmon but without any possible cure. There are many examples of how these viruses have been transmitted. In California, believe it or not, Atlantic salmon were being farmed using eggs transported from Norway. Those eggs contained the virus, which then took out the local population of Pacific salmon.

Some in the industry are in denial. The truth is that, when the salmon farms arrive, it seems that the wild population crashes. Examples include the loss of the sea trout runs on the Scottish west coast and the once-great salmon rivers in Norway. In British Columbia, on the Broughton archipelago, the wild pink salmon population was reduced by 80% by sea lice that came from fish farming. In Chile, ISA—that virus I have just spoken of—resulted in the collapse of the entire industry. Iceland saw huge protests, with about 1% of the population turning up to protest outside the Parliament about the possibility of fish farms being allowed to continue.

Wild fish interbreed, diluting the gene pool and reducing the ability of the progeny to make migratory journeys. This ability has been honed over hundreds of thousands of years by fish that are genetically unique to each river. They are breeding with the salmon from the farms. They are described as “Scottish salmon”. They are no more Scottish salmon than anything else. They are based on Norwegian salmon and are genetically modified to grow quickly. They are a million miles away in terms of their gene pool and structure from the fish that operate in the rivers of Scotland, each of which has a unique genetic identity and as a result is equipped to be able to run the river to spawn and to go out to sea and return after one or three years. If those fish interbreed with this alien species, the result is progeny incapable of making that journey and therefore the destruction of the population in the rivers concerned. And by the way, on the numbers escaping, in Loch Melfort in Scotland 48,000 fish escaped, dwarfing the wild population.

There is a growing realisation around the world of the environmental damage being caused. This is resulting in complete bans on fish farms. Alaska has had a ban since 1990. Argentina has introduced a ban. California has introduced a ban in state waters. In British Columbia, the plan is to phase out open-net farms by 2025 and move to closed systems.

[The Earl of Leicester (Con)]

My Lords, I declare interests as a trustee of the Burnham Overy Harbour Trust and president of the Wells-next-the-Sea RNLI station—I say that only because they both go out to sea. I apologise that I was not here at Second Reading on 2 September; I was in the Netherlands on business also relating to the environment. Like my noble friend Lord Trenchard, I agree that the main purpose of the Bill is to allow the Crown Estate to borrow and leverage against its assets and manage them in a way becoming of the 21st century.

I am astounded that the Crown Estate is not required to undertake the same level of environmental impact assessment that we do on the mainland. Amendment 37F is incredibly straightforward. It seeks to install in law a requirement for the Crown Estate to undertake an EIA, just like any other business on the mainland planning to undertake large-scale engineering works.

In preparation for this amendment, I spoke to a number of people in my local community on the coast of North Norfolk: Andy Frary of the Wells & District Inshore Fishermen’s Association; Bob Smith, the Wells-next-the-Sea harbourmaster; Leo Hambro, founder of Tidal Transit; and Professor Jenny Gill of the School of Biological Sciences at UEA—she is not really in my community any more, because she has just moved to Fife.

As the harbourmaster and I discussed, obviously the Crown Estate wants the rent, but this EIA needs to be rather more rigorous. If we insist that the Crown Estate will be required to undertake detailed environmental impact assessments, who will monitor that? Will it be the MMO? Bob Smith’s view is that the MMO is vastly removed from the coalfaces; it gives out the licences but has inexperienced staff and does not really understand local communities.

The fishermen I spoke to, the harbourmaster and I are very much for wind farms out to sea. We have marine protected areas and, ironically, once a wind farm is established, it becomes a sort of natural marine protected area. Rock armour is placed around the base of the wind turbines to protect them from big tides and scarring, et cetera. It then quickly attracts crustaceans—lobsters and crabs—and fish and there is a 50-metre “no fishing” rule for fishermen, who cannot get close to them. It is almost a sanctuary for all these crustacea. As they develop and thrive, they move out and the fishermen can then catch them.

There was also concern that giving licences to different companies for different wind farms was rather disjointed; they should be liaising on where their cables can come together out to sea so that they hit the land in one place. That has happened to an extent in North Norfolk, where they come ashore at Weybourne.

Professor Jenny Gill looks at this from an environmental point of view. The location of these wind farms is the most important thing. We need to avoid putting them where birds are—they are easier to monitor than fish and sea mammals. The concern is bird strike out to sea. Organisations such as the BTO and the RSPB have done a lot of work on flight heights of migratory birds and sea birds in relation to rotor speed and on whether bird strike is a big threat. Bob Smith surveys boats going out from Wells-next-the-Sea; maybe they are lucky and the wind farm they have been surveying is in the right place, but they come back and say, “We saw four birds today”. That damage is not happening.

In seeking this EIA, I am encouraging the Government to involve nature conservation organisations at an early stage so that they can be part of the planning process. Professor Gill mentioned that this is getting quite complicated. Beth Scott, professor in marine ecology at Aberdeen University, has worked on how tides work in open sea and form around tidal nodes and on whether putting static turbines on the ground changes the way tides work and the spatial way in which they move.

The big thing is making the planning process more transparent and getting conservation organisations at the table. They do not want to be adversarial; they are all at the green end of the scale and want to see a lot more of this renewable energy.

I had a very interesting conversation with Leo Hambro, of Tidal Transit. He operates crew transfer boats. I talked to him about the construction phase of these wind farms. He said that there have been improvements of late, in the last few years, including air bubble rings that are placed around the piling system which let out bubbles to reduce the sonic boom—which of course carries a long way underwater—therefore, we hope, mitigating damage to mammals. However, that has happened only recently.

When trenching, that is done either through some sort of underground machine that pulls a plough through the sand or, more often, through a large ship pulling a plough which turns over a trench a metre deep, into which the big cable is placed and then sand is placed back over it. If necessary, a few more rocks are placed on top of it. However, there really ought to be an EIA to decide which route these cables take. I suspect they probably take the shortest and cheapest route, but do they avoid mussel lays? They must avoid sunken ships, but off the coast of north Norfolk, in Cromer, we have a very important chalk reef, and it is important that that is protected.

To go back to crew transfer boats, Leo Hambro has seven of them. In fact, there are 200 around the UK and 700 around the world. Some 80% of them are in the UK and Europe because of the large-scale wind farms we have out to sea. To explain, these boats go out every day and take engineers to maintain and man the wind farms. The average stat for the industry is to use 1,500 litres of red diesel a day. In reality, he said they could use 2,500 to 4,000 litres a day, particularly if they are servicing a wind farm which is 45 miles away. He has to service East Anglia ONE from Lowestoft. These boats are going at 20 knots, so they are burning a lot of diesel.

It is not the case that when they get out there they switch their engines off. They have to spend up to two hours pushing against the turbine to make a safe platform for workers, transferring kit on and off the boat, et cetera. When they are then waiting for another three hours or so for the engineers to do their work, they have to stand off, but they do not drop an anchor and switch off; they have to run their engines to maintain generators and such on-board.

Leo Hambro is operating boats out of Wick, Grimsby, Great Yarmouth and Lowestoft. An interesting point to which I hope the Minister pays attention is that one of his boats is being converted to run on pure electric. That is being done in Great Yarmouth and should be ready for May 2025, thanks to DfT UK SHORE funding. It also includes offshore and onshore charging infrastructure, which I will come to in a second. The reason I mention these boats is that, for 200 boats using 2,500 litres of red diesel a day on average, five days a week, 50 days a year, that is 125 million litres of diesel.

That takes me to exhausts. AdBlue is added to the exhaust to reduce toxins, including nitrous oxide and sulphur oxide, and diesel particulates. AdBlue is made of synthetic ammonia—

[Lord Forsyth of Drumlean (Con)]

Watch the time.

[The Earl of Leicester (Con)]

Am I not allowed 15 minutes?

[Lord Forsyth of Drumlean (Con)]

No.

[The Earl of Leicester (Con)]

My apologies—this is it. AdBlue is not made from green ammonia. All these marine exhausts omit their fumes below the water to keep the exhausts cool. AdBlue is depositing heavy metal poisoning into the sea. I will stop there.

[Viscount Thurso (LD)]

My Lords, I will speak to this group of amendments. I was not sure which one most suited the comments I wished to make, but I think it is probably Amendment 37F in the name of the noble Earl, Lord Leicester.

At the heart of all three amendments is a question about the relationship between, on the one hand, the economic activity that we wish to undertake, quite properly, and, on the other, the environmental and natural consequences that may take place. It is about the right balance between what we seek to do economically and what we seek to protect environmentally. I will speak to that general point.

Taking my lead from the noble Lord, Lord Forsyth, I should declare my interests. I too am an angler, although I do not get to spend nearly enough time on the river, and I also happen to own the river, which is rather nice. I am chairman of the Caithness District Salmon Fishery Board, which is currently very involved with Crown Estate Scotland on various issues. I may also be—I hope—the beneficiary of a number of renewable projects. I have every sort of interest that you could possibly have; I think that they are broadly covered by my register, but I thought that I had better spell them out.

As I said, the heart of the three amendments is about seeking to ensure that, when we set out to undertake an economic activity of any kind—and this is absolutely what happens on land—we make a proper and full assessment of what the impact is likely to be on the environment that we are putting that economic activity into. That includes the flora, fauna, fungi and everything else that you might find there.

I want to give one quick example; it is in Scotland but I think it is relevant. We on the north coast have four rivers which are all in very good health. On the Thurso we electrofish every year and for some years now we have known that you cannot get any more juveniles into the river, it is in that good order. So, at a time when most of Scotland has salmon stocks that are endangered, as the noble Lord pointed out in introducing his amendment, we have the one bit of Scotland that actually is in good order and producing good salmon—and long may that last.

The west of Shetland wind farm, which is going to go ahead in the not-too-distant future, and which I support as a piece of offshore energy, may have a problem for us in the fishing world, and that is that we do not know where our smolts go. When the salmon grow in the river, they come to a point where they smoltify and they take to the sea and off they go. They are then called “smolts” or “post-smolts” and we do not actually know where they go. There has been smolt tagging and tracking in the Moray Firth which discovered that the fish that come out of various rivers in the deep south around Inverness and places like that have a tendency not to do what you would expect, which is to scoot up the coast and head past Orkney. For reasons known only to them, they leg it across to Aberdeenshire, which I always thought showed a bit of a lack of taste. The point about that is they do not go through the Beatrice wind farm and that piece of knowledge is vital in being able to look at what you may need to do to mitigate.

Similar studies on the west coast show that Irish and west coast fish tend to go due north, as you would expect, and straight off to Iceland. We just do not know where our smolts are going, so we made contact with Crown Estate Scotland, which I have to say has been incredibly helpful on this, and the chairman put me in touch with various people. As a result, I believe that there will be a smolt-tracking project which will allow us to know where our smolts are going and we will therefore know whether we have a problem, so we can look at what can be done to mitigate it if we have.

That comes back to the point I was making that, without information, you cannot make a decision on the appropriate thing to do. Crown Estate Scotland on this occasion has been extremely helpful, as I said. It wishes to make sure that it does the least harm, which is wonderful, but it seems to me correct that, in forming any legislation, it is appropriate, as we do with the nuclear industry and a whole range of other things, to state what it is that people have to provide by way of information in terms of an economic impact assessment and what they will do to mitigate the inevitable downsides that occur when you have developments of these kinds.

So I am not sure whether I am supporting anybody in particular—noble Lords will have to make up their own minds on that—but I am supporting the principle that we need knowledge and information about what may happen so that we can then make an informed choice on what mitigation is required and how much damage we are prepared to accept for the value brought by the economic activity.

[Lord Forsyth of Drumlean (Con)]

I am most grateful to the noble Viscount for giving way and I am much heartened to hear that his rivers and fish are doing very well. I just wonder what his reaction would be if someone decided they wanted to put a fish farm in the track of his migrating smolts when he knows where they are.

[Viscount Thurso (LD)]

I suspect I would be pretty horrified, given all the information that I know about it, but I have long tried to stick to a principle in your Lordships’ House to speak about what I really know about and avoid the things I do not know too much about, so I hope the noble Lord will forgive me if I do not go down that road.

To come back to my central point on the need to get information, it is about the right duty that we should ask the Crown Estate to have and then the process it should follow to deliver it. So my request to the Minister would be to look at the obvious strength of feeling on all of these points and perhaps the Government should look at what their view would be as to the right process and the right way to put it into the Bill and come back with an amendment that would achieve that and would suit the Government.

[Lord Livermore (Lab)]

I am afraid that is not something I know about, but I am happy to write to the noble Earl.

[Lord Forsyth of Drumlean (Con)]

My Lords, I am grateful to the Minister for that reply, which was clearly written by Treasury officials who do not get out very much. The Minister has been kind enough to say that we should indicate whether we think the existing legislative requirements and regulations are working. We have just had an excellent debate, which has made it absolutely clear that wild salmon are being destroyed, not just in this country, but elsewhere, so the answer is: it is hurting, and it is not working. A very modest requirement on the landlords, the owners of the seabed to—

[Lord Livermore (Lab)]

Just to be clear, I wanted clarification as to whether the existing legislation could work, or, in itself, could not work.

[Lord Forsyth of Drumlean (Con)]

I would be very happy for the Minister to come back with an amendment that would indicate how it could be made to work, because it is not working. It seems to me a very modest measure that would say to the Crown Estate that it has given a licence to these people, so it is therefore under a duty to make sure that they act in accordance with all regulations and in a way which protects the environment for which they have responsibility. I cannot imagine why the Minister would reject that.

In view of the very inadequate response, I am very tempted to test the opinion of the Committee, but I will not because I hope that, perhaps in further discussions with the Minister, we can get an amendment which will actually offer some degree of protection to the hundreds of thousands of fishermen who are concerned about this, to the communities who are concerned about this and to the many, many people on a cross-party basis. I cite the example of the noble Baroness, Lady Jones, and I who are united; we are linked at the hip in our determination to make this happen.

However, I would like to thank everyone who has spoken in the debate in support of not just my amendment but that of my noble friend Lord Douglas-Miller, who made a very fine speech explaining precisely why things are not working. I am grateful to my noble friends Lord Trenchard, Lord Strathclyde, Lord Moynihan and Lord Caithness, the noble Baroness, Lady Jones, of course, and the noble Earl, Lord Kinnoull—it is quite a gathering. The Minister ought to go back and think about this again, and we will table a further amendment on Report.

I am most grateful to my colleague my noble friend Lord Roborough for the support that he gave to this amendment and his careful consideration. I have to say that I am not sure the Minister’s officials have shown the same diligence in looking at what is a major problem which, if not tackled with immediacy, will see the extinction of the wild salmon in this country. That is not something that any Government would want on their record. Given the response, I beg leave to withdraw my amendment.

Amendment 37 withdrawn.

--- Later in debate ---

[Lord Livermore (Lab)]

I am happy to write to the noble Earl on that point. In the meantime, I hope he will feel able to withdraw his amendment.

[Lord Forsyth of Drumlean (Con)]

The Minister has not really addressed the fundamental point made by the noble Earl, Lord Kinnoull: fish and birds do not know where the border is between Scotland and the rest of the United Kingdom, and there are common interests. All he has done is read out a list of regulations and statutes that apply to the two commissions. I think the noble Earl was asking what provisions can be made, so that the two sets of commissioners are able to operate in the interests of the United Kingdom as a whole. As a unionist, he will surely appreciate the importance of that.

[Lord Livermore (Lab)]

What I read out was a response to the amendment tabled, which asked for exactly that; that is why I read it out. The noble Lord raises profound constitutional questions which I may not be the right person to address them to.
