Alosa agone is a species of ray-finned fish in the genus Alosa. Alosa agone is an endangered species of the Alosa genus.[2]
Species description
Alosa agone are common in the Mediterranean and the western Balkans.[2] There are also landlocked populations found in Italy.[2] The distribution of reproductive communities and the conservation status of Alosa agone in the central and eastern parts of the Mediterranean areas are poorly known.[2]
Conservation
Alosa agone’s numbers have declined due to barriers such as dams in their local areas. [2] These barriers prevent them from getting upstream to their spawning grounds and reproducing.[2] Improved water quality in some landlocked lakes have increased their numbers in recent years.[2]
Biology
The "twaite shad" are known to be very adaptive and variable as they form landlocked populations in Italy and its neighboring areas, including the western Balkans.[2] They can modify their morphology and biology according to their environment.[2] Therefore, Alosa agone, just like many Alosa species, can be either marine or freshwater fish.
