Total Allowable Catches: Fisheries Negotiations

Jim Shannon Excerpts

Wednesday 18th January 2023 Westminster Hall

[George Eustice (Camborne and Redruth) (Con)]

I beg to move, 

That this House has considered the methodologies for setting total allowable catches for data-limited stocks in fisheries negotiations.>

It is a real pleasure to serve under your chairmanship, Mrs Murray. It is very appropriate for you to chair this event since, as every Member present knows, your knowledge and experience of the fishing industry is unrivalled in this House. I am sure that, were you not being impartial in chairing the debate, you would have plenty to say on the matter.

In my time as a Department for Environment, Food and Rural Affairs Minister, I had two key observations. First, every Minister comes in with plans for the environment, and one of the first things they need to learn is that the environment has plans for them, too, and they are not always very pleasant.

The second truth is that every Minister coming into DEFRA says that they will have an evidence-based approach and will follow the science. But when they ask the scientists what should be done, they find that the scientists are not quite sure. They talk about evidence gaps and things that they do not understand, and are reluctant to come up with a clear policy proposal. That means Fisheries Ministers in particular are inevitably left with the thankless task of trying to make policy decisions with imperfect evidence, but making the best use of the evidence that they have. Nowhere is that conundrum more complex than in fisheries.

I recall a fishing representative giving evidence to a Select Committee. As he put it, fisheries is not rocket science; it is way more complicated than that. There are uncertainties in the science and in the way we calculate maximum sustainable yield. There are difficulties, for instance, around assessing the age of a fish. The basic approach to maximum sustainable yield is to allow fish to reproduce for at least one generation, and that stock should be sustainable. Typically, scientists measure the average length of fish when they are landed to try to assess the age of the stock and its reproductive capacity. That is the essence of the calculations that take place.

But there are difficulties all round. First, fish of different ages tend to inhabit different parts of the ocean, and trying to make sense of that can be difficult. It can be a hit and miss science to understand exactly what the average length of a fish is, given that they are very mobile and move around.

[Jim Shannon (Strangford) (DUP)]

I thank the right hon. Gentleman for securing this debate. I am extremely interested in what he has to say, and I spoke to him beforehand. I have one example of the importance of data. We have witnessed a remarkable turnaround with spurdog. In a most important fishery, limited data led to a ban on landing the species. However, the situation has changed dramatically, based on the data for 2023, with a total allowable catch agreed with the European Union for the year ahead based on up-to-date scientific advice. A statutory instrument is to follow, as the Minister knows. That is because of the data-limited status and the evidence that has made the change.

[Mrs Sheryll Murray (in the Chair)]

Order. This is a 30-minute debate. If interventions are to be made, can we make them short and snappy, please?
