| The Teutonic Knights built two saltworks in Ciechocinek which operated until the end of the 18th century. |
| Most birds only frequent these saltworks when their salinity is low to medium. |
| Two other trials also led to results which allowed the saltworks to operate for more than 60 years. |
| The bay is of economic importance for the sharks and other fishes in its waters and for the saltworks on its shores. |
| The saltworks areas are subject to the same risks as the lagoon and estuary biocenoses, i.e. heavy anthropisation. |
| Another reason why birds prefer saltworks is that hunting prohibition is more effective there than in the rest of the wetlands. |
