In the entire Hvide Sande and Ringkøbing Fjord area there is an abundance of fish species. That is because the area has both saltwater, freshwater, and brackwater in the fjords, lakes, streams, and rivers.
Ringkøbing Fjord consists of saltwater by the water locks and freshwater in the northern and southern ends, and in Skjern Å, both saltwater-, freshwater-, and brackish-water fish live. For example the, in Denmark, rather rare sea-, river-, and stream lampreys live in this area. Stream lampreys live in freshwater all their life, while the other two kinds of lampreys spawn in freshwater and mature in brackish- and salt-water.
In the river Skjern Å there is a decent population of the famous Skjern Å-salmon, which is the only original species of wild salmon on the European continent. This species of salmon can grow to weigh more than 20 kg.
The great conditions in the river Skjern Å have also benefited the sea lampreys which are an endangered species.
In the North Sea there are also plenty of fish. If you are an angler, you can catch flounder, cod fish, garfish, turbot, mackerel, sea-devil, lang, pollock, porbeagle, and many other species of fish.
