Otolith Morphometry and Fourier Transform Near-Infrared (FT-NIR) Spectroscopy As Tools To Discriminate Archived Otoliths of Newly Detected Cryptic Species, Etelis carbunculus and Etelis Boweni

January 04, 2024

Identification of both E. carbunculus and E. boweni in archived catch from Guam has important implications for fisheries management

Cryptic speciation was recently verified in Etelis carbunculus, an important component of federally managed bottomfish fisheries in the Pacific Territories of the United States. As a result, archived otolith collections used for fishery assessment are now contaminated with newly described E. boweni in areas where these species co-occur.
