Fisheries Bill [HL]

Lord Krebs Excerpts

Committee stage & Committee: 3rd sitting (Hansard - continued) & Committee: 3rd sitting (Hansard - continued): House of Lords
Monday 9th March 2020 Lords Chamber

In order to be effective, this must also be underpinned and supported by properly resourced and effective monitoring, control and enforcement. We are looking for the Minister to give a legal commitment on the face of the Bill not to fish above sustainable levels. I believe that the maintenance of sustainable fish stocks is the golden thread which runs through this Bill, so they must be protected. I beg to move.

[Lord Krebs (CB)]

My Lords, I rise to speak briefly in support of the amendment because it provides me with an opportunity to give part two of my lecture on maximum sustainable yields, although I detect that the undergraduate audience is less than enthusiastic about hearing it. However, I want to ask the Minister the following question. The classic textbook on maximum sustainable yield was written by William Ricker in 1975. In it he defined it as

“The largest average catch or yield that can continuously be taken from a stock under existing environmental conditions.”




The three key elements of that definition are “average”, “continuously” and “existing environmental conditions”. I hope the Minister will tell us whether, given that the Government are set on harvesting at MSY—which, as I explained earlier, I think is a mistake—there is a definition in their mind of “average”. To give three possibilities, is it the arithmetic mean, the geometric mean or the harmonic mean?

There must also be something in the Government’s mind about “existing environmental conditions”, which the noble Baroness, Lady Bakewell, already referred to. What does “existing environmental conditions” mean and how will the change in MSY be linked to changing environmental conditions? The Government must also have in their mind a definition of the word “continuously”. Perhaps the Minister could clarify those points for me.

[Baroness Worthington]

My Lords, I cannot say much more than the noble Baroness has already said, very eloquently. I lend my support to this amendment because it addresses a fundamental question about Clause 23.

In the next group we will discuss some of these issues in relation to Clause 25 in great detail. For now, I fully support the idea that we should be putting these conditions into this agreement. It is similar to my Amendment 103, so I do not want to rehearse it, but I was struck by the noble Baroness’s comments about the fact that we should be managing this stock for future generations and not simply for the short-term economic needs of those who are benefiting from the status quo.

Not to trivialise the debate, but my children are engaged in the marine environment for a number of reasons, not least through watching the wonderful BBC series “Octonauts”. The Octonauts’ phrase is that we should explore, rescue and protect. I hope that the Bill can be transformed into one which enables us to explore the fishing industry with data, rescue those stocks that are in need of respite and their levels to be restored, and protect the socioeconomic conditions of the whole fishing industry, not just a subset.
