Trophic Impactによれば(米崎ほか 2016)、沖底１そうびきによるモデル機能群への影響は大きくなかった。一方で、大型定置網の漁獲物の平均栄養段階は低下しており、生態系全体への影響が懸念された。小底の漁獲物の平均栄養段階は変動が大きく、長期的には増加しており、生態系全体への影響が懸念された。海底環境への影響については、沖底オッタートロールでは重篤な、小底では一部で悪影響が懸念された。大型定置網は着底漁具ではないが、網を固定するアンカーが多数海底に接触している。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"2.
