Human activities related to aquaculture and professional fishing in the Park's wetlands are both allowed and encouraged as they are very important from the economic and employment points of view and in some cases they also have a strong historic, folklore and cultural value.
The Delta area features different types of waters: The "Valli" (valleys) are the inland freshwater, brackish or saltwater basins whose communication with the external waters (rivers or sea) is obtained artificially via gates and/or water pumps. The most iconic examples of this are the "Valli di Comacchio" and the Campotto Expansion Tanks and Valle Mandriole.


The lagoons are freshwater, brackish or saltwater basins that communicate with the sea via large openings that allow the tides to ebb and flow, for example in the Sacca di Goro. Lastly there are some inland valleys that are nonetheless free to communicate with the sea: these basins are influenced by the tide influx via the channels (Valle Fattibello, the "Piallasse" (flat valleys) in Baiona and Piombone).
The broad concept of fishing, including any action focused on capturing fishes, comprises several different types of activities: professional fishing, which includes molluscs collection, and sports fishing.
Sports fishing is normally allowed inside the Park or Pre-Park areas except for "A" areas and particular areas identified by the Territorial Plan and specified in the Regulations; in these areas the environmental conditions, the presence of species whose preservation is particularly important or the fact that these areas host delicate stages of the fishes' life cycle make temporary or permanent bans on fishing necessary.
However, even where fishing is allowed, it must be carefully monitored and regulated by the Managing Authority for the purpose of guaranteeing preservation of the fish fauna in the Protected Area, especially for what concerns species that are more relevant from a wildlife preservation point of view.
The Po Delta Park also hosts aquaculture, which is different from normal fishing (which is just collection of a natural resource). Valliculture is a type of traditional and extensive fish farming that has been carried out for centuries in the Po Delta Valleys. Fishes are captured using their mass migration flows, namely their leaving the inland basins for the sea. Fish catching is made by means of a peculiar device called "lavoriero" (fish trap) in the areas close to the farming basins.
In compliance with Chapter X of the Regional Law no. 3/99 of January 1, 2000, the Emilia Romagna coastal provinces have been delegated to carry out administrative functions of concession, payment of contributions and control on funds allocation describer in Regional Law no.3/79 (purchase of boats and boat equipment, processing systems, marketing and storage of fish products, means of transportation and so on).
