UC San Diegoスクリップス海洋学研究所の研究者は、太平洋のサンゴ礁に生息する1,308種の魚の体長と体重の関係をまとめた新しいデータベースを公開した。これにより、魚を捕獲せずに目視調査から個体や群れのバイオマスを推定でき、漁業管理や生態系評価に役立つ。従来データが不足していたラブラ科やアオバス科なども近縁種の情報を加えて体系化され、非侵襲的かつ標準化された評価が可能になった点が大きな進展である。データは過去5年間の文献から集められ、今後も更新される予定で、科学者や保全関係者にとって重要なツールとなる。成果は『Scientific Data』誌に掲載された。

Abstract

Length-weight parameters assist in the estimation of a fish’s biomass based upon assessment of length, providing value to many scientific and management applications. Some fish species have many sets of parameters published, while those less commonly studied may have no available information, making it challenging to decide which values to use. To address this, we present a database of quality-controlled length-weight parameters for 1,308 Pacific coral reef fish species from 87 families. The species included are commonly observed in visual censuses of shallow (10 m depth) forereef habitats of the central Pacific. These data were collated from the literature, and were selected based on study sample size, representation of the species’ total length range, and data confidence. The most speciose families, wrasses (Labridae) and damselfishes (Pomacentridae), were most common in our database, though a large proportion of these species remain data-poor. In total, this database serves as a valuable tool for the academic community as well as for partners and managers desiring to learn more about coral reef fish assemblages.
