''Arripis'' is a genus of marine fishes from Australia and New Zealand, known as Australian salmon, kahawai and Australian herring. They are the only members of the family Arripidae. Despite the common name, Australian salmon are not related to the salmon family Salmonidae of the Northern Hemisphere, just as Australian herring are not related to herring of the Northern Hemisphere, but belong to the order Perciformes of perch-like fishes. Australian salmon were named so by early European settlers after their superficial resemblance to the salmoniform fishes. Relatively long-lived fish, Australian salmon are a favoured target of recreational fishers, and both commercial and traditional Māori fisheries. They are also common bycatch of the Australasian snapper (''Pagrus auratus''), mullet (Mugilidae), white trevally (''Pseudocaranx dentex''), and mackerel (Scombridae) fisheries. These species are all taken in great numbers by way of purse seine nets and trawling. They are also caught by skilled fishermen along the southern coastline of Australia by beach seining. Due to declining numbers and ever-increasing annual catch sizes, the future viability of the Australian salmon stock has been put into question. == Species and range == There are currently four recognised species in this genus. The ranges of the species may overlap to some extent, but can be described as: * ''Arripis georgianus'' (Valenciennes, 1831) (ruff, tommy ruff, Australian ruff, Australian herring): Gippsland Lakes, Victoria to Shark Bay, Western Australia * ''Arripis trutta'' (J. R. Forster, 1801) (Australian salmon, eastern Australian salmon, ''kahawai''): From western Victoria to New Zealand, including the islands of Tasmania, Lord Howe, and Norfolk * ''Arripis truttaceus'' (G. Cuvier, 1829) (western Australian salmon): Western Australia to Victoria and Tasmania * ''Arripis xylabion'' Paulin, 1993 (northern kahawai, ''kermadec kahawai''): New Zealand, west to Lord Howe, Norfolk and Kermadec Islands 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Arripis」の詳細全文を読む スポンサード リンク
