宜春首次發現東方墨頭魚 為中國特有的原生魚

晨報訊(羅昊 記者 李小聰) 近日,記者獲悉,江西省宜春市首次發現中國特有的原生魚——東方墨頭魚。

據了解,這條東方墨頭魚全長15.7厘米,體長13.5厘米,重47.2克。東方墨頭魚是一種小巧而珍稀的淡水魚類,隸屬于鯉形目、鯉科、野鯪亞科、墨頭魚屬。它的體形獨特,呈圓筒形,腹部扁平,尾部側扁,頭寬,吻圓鈍,前端有很多粗糙的角質突起。鼻前深陷,將吻分作兩部,上部為游離的吻突,雄性更為顯著,并具發達珠星,幼魚不明顯。在外貌上,東方墨頭魚的背部呈深黑色,而腹部呈灰白色,它的體側每個鱗片后部都有一塊黑斑,因此,在體兩側形成了6條黑色平行條紋。它們喜歡棲息在江河、山澗溪流的湍流環境中,靜止時,它們會用自己吸盤狀的嘴巴吸附在巖石上,營底棲生活。

據悉,東方墨頭魚對水質要求很高,在贛江下游豐城段內發現“東方墨頭魚”這一物種,既是生態環境優良的體現,也是推進禁退捕工作后物種多樣性恢復的表現。
