Summary in Japanese:
イカは、マグロと並んで毎年、全国の水産物消費量の2位か3位を占めています(トップはサケ)。スルメイカの漁獲量はイカ全体の8割を占め、日本人にもっとも馴染みのあるイカです。その一方、水槽での飼育が難しく、海中での卵塊や幼生の実態も解明されておらず、謎の多い生き物でもあります。

日本海側の主要な水産物だったスルメイカの水揚げに、近年大きな変化が起きています。東北や北海道東部での漁が盛んになり、「本場」函館の漁模様に年による変動が目立ってきました。また、近年のダイオウイカブームに続き、昨年、「イカが空を飛ぶ」というニュースが大きな話題を集めました。

本書の著者、桜井泰憲さんは、30年にわたりイカの生態を研究しつづけるとともに、知床世界自然遺産地域科学委員会の委員長を務めるなど、オホーツク海を中心にした海洋環境についても研究を重ねてきました。また北海道大学水産学部は同氏のもと、イカ研究の最先端を走り、空飛ぶイカの行動も世界で初めて詳しく解明しました。

本書では、基本的な生態のほか、著者の長年の夢を実現した大型水槽での飼育実験の最新成果、漁火に集まる行動の詳しい分析、著者が開発した鮮度保持の秘密兵器「イカ活チャ器」の効果、100年後のイカ漁の予測まで、興味深い話題を豊富に収めています。
