Fresh fish is the most important
Do you know where the oldest fish farm in Continental Europe is? It's in Poland, near Częstochowa, on the edge of Jura Krakowsko-Częstochowska in Złoty Potok. Here the crystal clear water of Elżbieta and Zygmunt sources have for decades flooded the ponds of Pstrągarnia. In the middle of the XIX century, count Edward Raczyński decided to build a fish farm at the source of the Wiercica River.
