【神戸沖メガロベントス調査】

#show(): File not found: "bethos5_500_08.jpg"

わたしたちは、地元の海に「どんな生き物がいるのか
調べて記録を残す」ことをはじめました。
そこに何がいるのか、変化はあるのかという
単純な興味に加え、得られた情報を記録・発信する
ことを通じて「里海」意識の普及も目指しています。

神戸の沖合では「小型底曳網漁」が行われており、
あるとき漁業者の方から「大量にヒトデが発生して困っている」という相談を
持ちかけられました。しかし対策を講じるにも、いったい何ヒトデが、いつ、
どこで、どの位発生しているのかという基本的なことが何もわからない状況でした。

そこでヒトデの挙動とあわせ、海域の底生生物をモニタリングするため「神戸沖
メガロベントス調査」を2012年から始めました。漁協や漁師さんたちの協力で
サンプルを集め、専門家による同定や計測など調査を行い、神戸の海にすむ生物相とその変化を把握する試みです。

1回目(第1回目試験的実施)

日  時: 2012年(平成24年)11月10日(土)13:30~17:00
場  所: 神戸市漁業協同組合ノリ採苗場(垂水区平磯)
参加者数: 22名
協力機関: 須磨海岸生物調査研究所、大阪市立自然史博物館、神戸市漁業協同組合
      大阪湾海岸生物研究会、神戸大学サイエンスショップ、
調査対象: 2012年(平成24年)9月・10月の底曳網漁による8サンプル
調査内容: 冷凍サンプルを解凍後、確認した生物をソーティング(分類)し、
      それぞれ種の同定を行った。計数可能な場合は個体数も記録した。

結果概要: 

  • 須磨沖の数サンプルからヒトデ類のスナヒトデ、モミジガイが多数確認できた。漁協側から指摘されていたヒトデ大発生に関してはまだ何もいえないが、沖合で多数発生するとすれば少なくともこの2種は可能性がある。
  • エビ類では、サルエビ、アカエビが量的に多かった。
  • シロザメ、アカエイの幼魚を確認、周辺で繁殖していることがうかがえる。
  • シロサバフグ、アカタチなどの幼魚が確認された。
  • ヒメコトヒキ、コロダイなど大阪湾では比較的記録が少ない魚種が確認された。
  • ウミエラ、ウミサボテン、ムラサキハナギンチャクなど海底の砂泥中にすむ刺胞動物も採れていた。
  • ユニークな名前のウニ類、ブンブクチャガマ、オカメブンブクがいた。

成果および課題など

  • 図鑑等でもあまり見られないユニークな生物が多く、観察だけで多くの参加者が楽しめた。
  • 海洋生物の専門家が多数参加していたため、種の同定は比較的迅速に行われたが、標本数が多いサンプルもありデータ処理に時間を要した。
  • 8サンプルは4隻の船によるものであったが、サンプルの採り方にはかなりばらつきが見られた。
  • ヒトデ類の挙動などテーマ設定して調査を継続するには、サンプリングの方法や処理・計測方法等について検討が必要。
