Abstract

A wreckfish,Stereolepis doederleiniLindberg et Krasyukova, 1969, inhabits typical cold or temperate waters and was previously known from Great Bay (Sea of Japan), Korea, south to Kyuhu-Palau Ridge of Japan. In the present report, a specimen of this fish was collected from southeastern Taiwan representing the southernmost distribution of the cold-water genusStereolepisin the Northern Hemisphere, with a southward extension into the tropical region. It is also the first record of a member of the family Polyprionidae from Taiwan. Here we document the species found in Taiwan, with a detailed description of the specimen.

Highlights

  • The wreckfish family Polyprionidae is a group of large marine fishes, growing up to 250 cm in length, and attaining high market values by some of its members (Froese and Pauly 2021)

  • Noichi et al (1990) studied the ecology of juveniles of S. doederleini based on 106 individuals collected from Yanagihama beach of Nagasaki Prefecture, Japan

  • Kwun et al (2018) reported juvenile S. doederleini collected from Jeju Island, southern Korea

Summary

Introduction

The wreckfish family Polyprionidae is a group of large marine fishes, growing up to 250 cm in length, and attaining high market values by some of its members (Froese and Pauly 2021). The family comprises 2 genera and 4 species, including Polyprion americanus (Bloch et Schneider, 1801) (nearly circumglobal; absent in Pacific coast of South America and northern Pacific), Polyprion oxygeneios (Schneider et Forster, 1801) (circumglobal in the Southern Ocean), Stereolepis gigas Ayres, 1859 (northern Pacific), and Stereolepis doederleini Lindberg et Krasyukova, 1969 (northwestern Pacific). Of these species, S. doederleini was previously recorded from around Great Bay, Korea to Kyuhu-Palau Ridge of Japan (Sokolovskaâ et al 1998; Choi et al.2003; Nakabo 2013). Kwun et al (2018) reported juvenile S. doederleini collected from Jeju Island, southern Korea. Moon et al (2011) studied the nutrition components of S. doederleini and suggested that it can potentially be a new aquaculture fish species
