Verification of the cryptic species Penaeus pulchricaudatus in the commercially important kuruma shrimp P. japonicus (Decapoda : Penaeidae) using molecular taxonomy

Abstract

Abstract. The kuruma shrimp Penaeus japonicus Bate, 1888 (Decapoda : Penaeidae) is economically important in the global shrimp market. It was regarded as the only species in the subgenus Marsupenaeus. However, our previous molecular analyses revealed two cryptic species (Forms I and II) in this species complex. In this study, we confirm the phylogenetic relatedness between the two cryptic species; revise their taxonomic status; and review their range distribution. The name Penaeus pulchricaudatus Stebbing, 1914 (with type-locality off the eastern coast of South Africa), previously considered as a junior synonym of P. japonicus, is fixed for Form II through a neotype selection. P. japonicus (Form I) is only confined to the East China Sea (including Japan, its type-locality) and the northern South China Sea. P. pulchricaudatus is widely distributed in the South China Sea, Australia, the Red Sea, the Mediterranean, and the western Indian Ocean. Phylogenetic analysis shows that P. japonicus is genetically homogeneous yet P. pulchricaudatus exhibits a strong phylogeographical structure. The Mediterranean stock of P. pulchricaudatus originated from the Red Sea population, supporting the Lessepsian migration hypothesis. The presence of two closely related cryptic species in the P. japonicus species complex provides important insights into fishery management and aquaculture development.

Air Exposure Affects Physiological Responses, Innate Immunity, Apoptosis and DNA Methylation of Kuruma Shrimp, Marsupenaeus japonicus

“…The Kuruma shrimp, Marsupenaeus japonicus, is an important commercial species that is widely distributed in the Indo-Western Pacific (Tsoi et al, 2014). Compared to other shrimps, M. japonicus have numerous advantages, such as fast growth rates, good reproductive capability, and survival during waterless transportation (Duan et al, 2016a).…”

Fine-Scale Population Genetic Structure and Parapatric Cryptic Species of Kuruma Shrimp (Marsupenaeus japonicus), Along the Northwestern Pacific Coast of China

“…We found that the sympatric areas range from Huilai (Guangdong) to Beihai (Guangxi) with a tendency change to some extent. In previous studies by Tsoi et al (2014), M. japonicus (var. I) was found to be confined to the East China Sea (including Japan) and the northern South China Sea.…”

“…The kuruma shrimp (Marsupenaeus japonicus), a commercially important crustacean, is widely distributed in the East and South China Sea, the region off Australia and the western Indian Ocean (Tsoi et al, 2014). Traditionally, M. japonicus was regarded as the only species of Marsupenaeus (Tirmizi, 1971;Lavery et al, 2004).…”

Comparative Study of the Gut Contents of Penaeus japonicus Bate 1888 (Decapoda: Penaeidae) In Semi-Intensive Culture and In Brackish Water Wild Environment

“…Both names are still used by various organizations and databases, eg. WoRMS (World Register Marine Species), FAO, DAISIE (Delivering Alien Invasive Species Inventories for Europe);however, in this study we will follow the most updated results Tsoi et al [1] for the definition of Penaeus and hence we will use the current name Penaeus japonicus Bate 1888.…”

“…Penaeus japonicus Bate 1888, the "Kuruma shrimp", whose taxonomical identity is still debated Tsoi et al [1], is an ideal species for aquaculture purposes, due to its adaptability to different environmental conditions Lumare [2]. The species is still indicated by means od two scientific names, i.e., P. japonicus and Marsupenaeus japonicus, due to a controversy in the status of the genus Penaeus Fabricius, 1798 (see, for example, Pérez Farfante & Kensley Ma et al [3,4].…”
