> However, I recently visited Chesil beach in Dorset and there were loads of cuttlefish bones on the beach. Hopefully that means there are loads of cuttlefish living and dying out at sea and I'll tentatively take that as a positive sign.
I routinely walk along the beach at Hengistbury Head (approx 40 miles further east) and have seen cuttlefish bones there for several years running. So perhaps, yes, there is a healthy population off the coast here.
[Edit] Went down a rabbit hole and found [0]. In summary, in the UK, cuttlefish are classified as shellfish in terms of reporting fisheries catches. Catches of shellfish have increased in absolute terms over the last 80 years, from 32k tonnes to 116k tonnes in 2022, and relative to catches of other fish. This is partly due to diversification of the fishing industry, partly because there may be fewer restrictions on shellfish catches.
The Channel is one of the UK hotspots for shellfish catching.
The Marine Conservation Society [1] states that "There is not enough data about cuttlefish in the English channel, but there are indications that populations are too small and fishing pressure is too high. There are no appropriate management measures for this species, despite high landings and high market value. Most cuttlefish are caught by beam trawling in the English Channel. This has the potential to cause damage to the seabed. Trawls can also have high bycatch, potentially of vulnerable species."

- 8A51C 3y agoConversly, my observations from Cornwall have been the opposite. I haven't seen cuttlefish bones in the numbers I would expect over the last few years. And the ones I have seen have been tiny. That is until this last weekend, when there were a great deal washed up and of a fair size, I too was joyed by this sight drawing the same conclusions as you did, that it was a good sign.
- pvaldes 3y ago> the ones I have seen have been tiny I may help here. As expected, the big ones are from adults in the cuttlefish fished commercially: Sepia officinalis in Europe. Around 1-2Kg or so. But the tiny bones are (most probably) also from adult cuttlefishes. There are several species of cuttlefishes in Europe. Like Sepia elegans that is locally frequent in the Mediterranean or Atlantic but only grows 8 cm in mantle. What you have seen is just a reflect of different phases on the ecosystem, the seasons, or the fishing techniques. After reproductive season or big storms a number of cuttlefish bones will strand all at the same time when the animals will die in mass.
