Yes, it is a sort carp, in dutch called: blankvoorn. englisch called roach or minnow (wikipedia). The most fish are all set back to water after catching. They taste like sh*t
But all the polish people how work here, catch them and eat them. At the moment there are so many polish people fishing in the dutch waters, that soms fish getting very rare!
There sure swims a lot of pike in the dutch waters. And they could get about 1.40! the largest I ever catcht was about 1.15. The beast cut trough my metal underline after getting it on shore!
The last 10 years i did not fish on pike anymore
bu with my new boat i sure will try it soon!
