The question of whether the bass stock has recovered is central to how the UK and the EU manage the bass fishery in 2026 and beyond — and it directly affects both recreational fishers and commercial fishers.

But it’s a difficult question to answer, for two reasons.

1. Scientific Uncertainty

The scientists can only provide an estimate of the bass stock level, because of various uncertainties.  The June 2025 midpoint estimate was about 25,000 tonnes, but the actual stock level could be considerably higher or lower than that.  The range of possible stock levels is shown by the green shading in the diagram below — from 19,800 tonnes to 31,400 tonnes.

This uncertainty calls for a precautionary approach to management.  If the bass stock were only just above the danger level, then increasing fishing pressure in 2026 would be a grave mistake.

2. What Level of Recovery Should We Aim For?

What should count as a “recovered” stock?

We believe the goal should be abundance — restoring an excellent bass fishery.

For recreational fishers, that would mean fewer blanks and a decent chance of catching a trophy fish.  For small-scale commercial fishers, it would mean higher catches per unit of effort, bigger fish that fetch more per kilo and higher profits.

We’ve seen what abundance looks like — in the 1980s, when the bass fishing was superb.

But the fishery managers are aiming for a much lower stock level called “BMSY” (the biomass level expected to produce the greatest tonnage of bass killed over time).  They want to shrink the bass stock by 8.7% in 2026.

Sea anglers and small-scale fishers on the Bass Management Group told Defra they want to continue rebuilding the bass stock instead, not shrink it. But despite this, Defra went ahead and agreed with the EU increases in catch limits to shrink the bass stock in 2026.
