What did they eat at the Crannogs in Scotland (UK)?

We have found traces of spelt and emmer wheat on site and barley. Also, a wide range of nuts and berries, including cloud-berry, raspberry, strawberry, brambles, sloes and wild cherries. Hazelnuts are in great abundance. Wild carrots, wild cabbages, wild garlic and thyme, and meat from domestic animals such as sheep and cow. Butter and cheese were found, but So far no fish bones have been found, but we have net weights.
