日本秋刀魚捕獲量慘跌:較去年同期銳減73%

Quick Look

日本今年秋刀魚漁獲量嚴重低迷,截至8月底全日本總漁獲量僅約1330噸,較去年同期大減73%。主因漁場遙遠且分散、魚群稀疏,導致捕獲量少且魚體偏小,平均價格更飆漲至去年的1.4倍。

Why It Matters

秋刀魚是日本秋季代表性魚類,今年因漁場環境與資源量問題導致產量銳減。

日本秋天最具代表性的秋刀魚,不過今年卻大缺貨。根據日本漁業資訊中心統計,到8月底為止,全日本秋刀魚總漁獲量只有約1330噸,比去年同期大減73%,產量最多的北海道根室市花咲港,也只捕了約1100噸,剩下去年同期的四分之一。

各漁港狀況都很差,花咲港年減75%以上,厚岸港約70噸、年減78%。只有釧路港逆勢成長,捕了約110噸,比去年增加63%,但整體來說還是非常低迷。原因出在漁場太遠又太分散,現在主要漁場距離花咲港約1000公里,而且魚群很稀疏,船開很遠也捕不到什麼。

不只量少,魚也偏小。今年捕到的秋刀魚,9成都是1尾80到140公克的小魚,過去那種油脂飽滿的大尺寸秋刀魚很少見。也因為缺貨,平均價格飆漲,1公斤均價932日圓,是去年的1.4倍,等於越小尾還越貴。

漁業資訊中心的渡邊一功部長表示,目前看起來秋刀魚的資源量本身就少,加上漁場遠、魚群薄,導致漁獲量起不來,只能期待接下來海水溫度下降後,魚群會比較集中,漁況才有機會好轉。今年日本民眾想吃便宜又大尾的秋刀魚,恐怕沒那麼容易了。
