Biodiversity Action Plan fish recorded in Sussex

This includes…

Allis Shad populations have declined significantly throughout Europe, in Sussex they are occasionally caught in estuaries or on the coast, and the near shore waters of Kent and Sussex are thought to be important for this species. They are mostly found in coastal waters and the estuaries of well-oxygenated rivers with good water quality.

Atlantic Salmon populations have declined by more than 80% in the last 30 years, and the UK population makes up a large proportion of European numbers. Eggs are laid in hollows in the beds of clean, well-oxygenated rivers. Following up to seven years in freshwater, they undergo considerable physiological changes that allow them to adapt to life in the sea. They will spend up to three years in the sea before returning to their birthplace to breed.

European Eel numbers have declined by as much as 95% in the last 25 years. They are the only European fish to leave the continent to spawn; migrating to the Sargasso Sea. Upon returning young eels (or elvers) enter rivers and can be found in a range of water bodies where they may spend up to 50 years before migrating to the sea. Some eels will not enter freshwater and instead remain along the European coastline.
