釣れた魚、先にやるのは血抜き?締め?冷やし?科学的な正解を解説

釣れた魚を美味しく持ち帰るために、最初にやるべきことは何でしょうか? すぐ締める? 血抜きをする? 神経締めをする? それとも、とにかく冷やす? 実は、締め方や血抜きにこだわっていても、「冷やし」が遅れると魚の劣化は進みやすくなります。 今回は、釣れた直後の魚をどう扱うべきかについて、魚のATP、乳酸、体温上昇、血液による酸化、微生物の増殖、潮氷と冷海水の違いなどをもとに、釣り場でできる現実的な処理手順を科学的に整理します。 結論は、 「動きを止める」 「血を抜く」 「すぐ冷やす」 この3つをできるだけ早く行うこと。 そして、その中でも最優先は「すぐ冷やすこと」です。 この動画では、氷だけのクーラーに魚を入れる問題点、常温海水バケツで活かしておくリスク、神経締めの優先度、潮氷で血抜きする意味、フリフリ血抜きのメリット、保存用冷海水を分ける理由まで解説します。 ナレーション by 動画制作会社VIDWEB(https://vidweb.co.jp/) ≪参考文献≫ Ando, M., Banno, A., Haitani, M., Hirai, H., Nakagawa, T., & Makinodan, Y.
