Conversly, 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. |

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.
