Shellfish Aquaculture

Daniel Zeichner Excerpts

Wednesday 15th March 2023 Westminster Hall

[Daniel Zeichner (Cambridge) (Lab)]

It is a pleasure to serve under you in the Chair, Ms Elliott. I, too, congratulate the hon. Member for Totnes (Anthony Mangnall) on securing the debate, on his introduction and on his account of the issues facing those working in aquaculture. I suspect I will cover much of the same ground, although possibly in a slightly different order and with a slightly different take on one or two points. I am, as ever, grateful to those working in the industry for their advice. In particular, I thank Mike Cohen of the National Federation of Fishermen’s Organisations and David Jarrad of the Shellfish Association of Great Britain.

I hope the Minister will address four key issues. The first, unsurprisingly perhaps, is water quality and the Government’s continuing failure to clean up our water. I very much enjoyed the observations from my hon. Friend the Member for Huddersfield (Mr Sheerman). The issue, of course, goes way beyond aquaculture. I am sure the Minister will be disappointed to hear that I am not going to re-rehearse all the arguments now; they are, I am sure, very familiar to him and his colleagues. With the recent heavy rainfall, we are once again seeing huge quantities of human effluent being pumped into the seas, including into shellfish areas, which are supposed to have mandatory protection, whether that is under the water framework directive or the legislation that we carry forward. That is unacceptable and it directly impacts fishermen and their livelihoods.

The right hon. Member for Maldon (Sir John Whittingdale) made that point very persuasively, and I heard it directly myself when I went to West Mersea last year. The shellfishermen were clear that it was an all-too-regular occurrence that effluent discharged into the sea and meant they had to stop work. That has a direct cost for them, and it would be an avoidable one if water companies had invested in improvement rather than pouring out money to shareholders.

The point was picked up by Labour’s shadow Chancellor of the Exchequer, my right hon. Friend the Member for Leeds West (Rachel Reeves), when she visited the Fal Oyster Ltd fishery at Mylor in Cornwall last year. She told ITV News at the time:

“We just can’t afford to lose industries like this. It is about the heritage of Cornwall, it’s about what makes this place so special not just to people in Cornwall but to people all around the country. We need to hear and heed the warnings of fishermen here in Cornwall who are worried about water quality, who are worried about the impact that’s having on their ability to sell their produce here and abroad.”

She was absolutely right. I suspect that she is probably quite busy at the moment, but I ask the Minister to tell us what assessment the Government have made of the impact of poor water quality on the aquaculture sector.

If that is a relatively well-rehearsed discussion, the second issue is probably less familiar to those outside this room. It is the Government’s attitude to Pacific oysters. The industry view is pretty clear, and its call that we should “love them” makes a strong case that they are good for farmers, the consumer and the environment. Its case is that, with a low-carbon footprint and with no requirement for external inputs, the cultivation of the Pacific oyster represents a sustainable method of producing high-quality marine protein while providing employment and economic activity in coastal communities.

Of course, not everyone agrees—we have heard observations on this from other communities—because it is not a native species. Natural England and others are concerned about the impact on the marine environment. They say that feral populations of Pacific oysters have become established in Natura 2000 sites, sites of special scientific interest and marine conservation zones. They say that monitoring conducted between 2012 and 2017 in the south-west showed a large increase in Pacific oyster density. There are concerns that colonisation by the species will have a negative effect on the designated intertidal features of these protected areas. They say that that has already contributed to some sites declining into unfavourable condition, because of the alteration of the biotopes and therefore the loss of original biotopes that make up the protected habitat features within marine protected areas. They say that if populations are left unmanaged, the expansion of dense Pacific oyster populations will most likely reduce the extent of habitat features at the sites and could reduce species richness and change community composition, as well as the diversity of biotopes making up the habitat.

Therefore this is not a simple or straightforward issue. The industry argues—again, we have heard these points made—that with warming of the seas, attempts to cull the Pacific oyster are, frankly, unlikely to be successful, so it is better to manage and farm it. Although indigenous to western Pacific coasts, it is nowadays the world’s most globalised shellfish, with cultivation occurring in more than 50 countries. It provides high-value crops in all continents. In Europe, production in France, Ireland and Spain dwarfs that in the UK. As we have heard, production in France is in the region of 100 times that in Britain and attracts significant Government support.

The industry is therefore unhappy that the UK Government seem to stand alone in Europe in acting against the species. David Jarrad, chief executive of the Shellfish Association of Great Britain, writes:

“Do we actually want a UK oyster industry? For too long, the government has been sitting on the fence, and the failure of successive governments to deliver a consistent national approach is leading to poor conservation outcomes, as well as hamstringing our oyster growers…It’s time to get priorities straight, with proper leadership on this issue.”

There is the challenge to the Minister—the call for proper leadership.

The third issue, which returns us to more familiar ground, is the classification of harvesting waters. I was interested in the comments from the hon. Member for Strangford (Jim Shannon), but I promise I am not going to go there. We do things in a different way here —gold-plating, as the industry argues, compared with the way EU members do things, even though we supposedly work under the same legislation.

The Shellfish Association of Great Britain tells me that there is no evidence that our more restrictive system does any better than other countries’ more permissive ones. Our system is based on taking one sample a month from waters that change on an hourly basis because of tidal flows. I am told that it has been shown that one sample is often entirely different from another sample taken from the same place at the same time. The test method has been shown to be more variable and less accurate than other approved test methods. The association argues that the system needs to be changed, to be more in line with other countries, so our industry is not disadvantaged.

I hear those points and have considerable sympathy with them. Again, we heard reference to the work of the Food Standards Agency. I would be grateful if the Minister gave his take on what the FSA has done so far, and what more can be done. Of course, safety always has to be highest priority, but it is fair to ask why our fishermen are being held to higher standards than their competitors. What is stopping him levelling the playing field?

[Mr Sheerman]

I always defer to my hon. Friend as the Member for Cambridge, expecting him always to know everything about everything scientific. Could he tell me whether there is evidence that we are overfishing oysters? Is there a decline in stock? Should we stop? I have given up red meat. Should I also give up oysters?

[Daniel Zeichner]

I am terribly sorry to disappoint my hon. Friend: I do not know everything about everything. I would not pretend to do so, and must go away to seek advice on that question. I suspect that the Pacific oyster is plentiful, and there is plenty of opportunity to make more of it. I do not suggest that he needs to give up.

[Angus Brendan MacNeil]

The long list of companies from my constituency of Na h-Eileanan an Iar that I read out would encourage the hon. Member for Huddersfield (Mr Sheerman) to eat oysters and mussels, as well as a variety of other shellfish. I would also like to mention an advertisement that I missed out, which is that they are operating in class A waters probably all year round.

[Daniel Zeichner]

I am grateful for the intervention. Finally, I return to a familiar theme, which we discussed at length in the Chamber with the previous Secretary of State: trade with the European Union. Since Brexit, we have lost our main market for live bivalves, as it is now much harder to sell them from class B sites. As I recall, it was such a difficulty initially that the Government offered short-term help, while, as we have heard today, blaming it on the European Union.

[Anthony Mangnall]

Will the hon. Gentleman give way?

[Daniel Zeichner]

I thought the hon. Gentleman might not be able to resist the temptation.

[Anthony Mangnall]

I am sorry, but I will be brief. It is worth being clear on this, because there is not a broad amount of disagreement in this debate. We have not lost that market. Current export figures are going in the right direction. It is a case of our saying that more work needs to be done. Exports are reaching that market; it is not “lost”, as the hon. Gentleman termed it.

[Daniel Zeichner]

Well, it seems to me that there were some who lost their businesses at that time. I do not think we should shy away from that. I would like to hear from the Minister what has happened over the past couple of years, and what is being done to secure a negotiated solution, to reinstate that trade, which had been possible over many years.

In conclusion, the aquaculture sector is one with considerable potential. Labour will sell, make and buy more food here. That is good for food security, for jobs and, I would argue, for the local environment. More will be produced locally, and we will expect the public sector to source at least 50% of food locally.

It is hard to disagree that the fishing sector more widely felt let down after the many promises that were made to them about Brexit. The reality was much more bureaucracy, much more cost and, in some cases, the end of business. One of my first visits as a shadow Minister was to King’s Lynn, where I met a processor who told me just how much extra work had to be done, contrasting the single form they used to fill in with the pile of manuals detailing how they need to proceed today. I have to admit that he cheerily told me it would all be worth it. I admired his pluck and optimism, but whatever one’s view on the issue today, I hope the Minister can explain what he and his Department are doing to reduce that bureaucratic burden, so that our fishermen can do what they do best, which is feed people, rather than fill in forms.
