Top Fish Seafood pand Top Fish Seafood is synonymous with top quality, guaranteed by the Gnodde family. Father Douwe is a former fisherman who founded Top Fish in 1992. He buys only the best quality fish at the fish auction in Urk, which is literally around the corner. Flat Fish is most commonly available there, such as plaice, sole and turbot, but he also buys fish via other channels, inlcuding cod, whiting, pike, pike-perch etc. Douwe Gnodde has spent all his life around fish, and the quality aspect certainly holds no secrets for him.
