          <datacite:description descriptionType="Abstract">世界的な人口増加にともない食料の需要が増大し、水産資源の安定的な供給が求められている。天然魚に次ぐ供給源である養殖魚に期待が集まっているが、周辺環境におよぼす影響や持続的な餌資源の開拓など、解決すべき問題を多く抱えている。本研究では、生態学的特徴から飼育環境と餌の問題を解決しうる魚種としてピラルクー Arapaima gigas に着目し、将来的な持続型養殖魚としての可能性を検討した。まず、閉鎖型飼育設備での成長率と飼料変換効率を調べたところ、短期間で高い成長率と飼料変換効率が得られた。つぎに、従来の魚粉依存型飼料の代替として植物性タンパク質を含有した餌での成長率を測定したところ、高い成長率を得た。以上の結果から、ピラルクーは閉鎖型循環設備において、魚粉に依存しない餌により飼育することができ、持続型養殖魚種として将来的に人類の動物性タンパク源となりうると考えられた。Aquaculture has attracted a great deal of attention due to ongoing decline in natural fish stocks. However, aquaculture has problems that need to be resolved, such as the impacts of the culture system on the environment, sources and methods of obtaining feed and so on. It said that pirarucu (Arapaima gigas) grow up much faster than other fishes. Therefore, this study investigated the potential of pirarucu as a fish culture species. First, experimental fish were cultured in an enclosed culture system using a commercial feed. Second, fish were cultured using a feed that contained plant protein. The growth rate and feed conversion efficiency of pirarucu were high in an enclosed system. The fish also had an adequate growth rate with the plant protein feed. Pirarucu is a suitable fish species for aquaculture.</datacite:description>
