Fishing crayfish- an old tradition i Sweden.
It´s mostly done under a full moon in August, with a lot of strong liquids inside to "keep the warm".. but this event is done for families living a special block of flats and therefor under sunlight, and with served hotdogs and potatoe-sallad on the other side of the small river...
One can´t be sure to get any crayfishes...

What we eat of the crayfish?
The meat in the claws.. and in the "tail".. just like a hobster or a shrimp...
