From 22 May to 10 June 2011 massive mortality of Prussian carp Carassius gibelio was observed in alluvial Lake Ř ehačka close to the Elbe River in the Czech Republic. More than 1400 kg of dead fish were collected and no other fish species were affected. Further molecular and cytogenetic investigation of fish (n = 232) revealed that the Ř ehačka population of Prussian carp consisted exclusively of gynogenetic triploid females. The causative agent was identified by means of molecular and electron microscopy as a herpesviral hematopoietic necrosis virus (Cyprinid herpes virus 2, CyHV-2). This is the first report of CyHV-2 from the Czech Republic and the second finding worldwide of CyHV-2 causing mass mortality of C. gi be lio. Some other localities in the upper Elbe River basin where C. gibelio was affected are also noted. We assume that the massive wave of deaths of all female gynogenetic Prussian carp can be attributed to limited genetic variation and the favourable conditions for development of viral disease.

“…Recently, along with the application of cytogenetic and molecular bio-techniques, the polyploid gibel carp has been extensively identified and found in many countries of the Eurasian continent, e.g. in Britain [34], Italy [34], Germany [34], Hungary [35], Greece [36], the Czech Republic [37,38], and Kazakhstan [39].…”

A unisexual species is generally associated with polyploidy, and reproduced by a unisexual reproduction mode, such as gynogenesis, hybridogenesis or parthenogenesis. Compared with other unisexual and polyploid species, gibel carp (Carassius auratus gibelio) has a higher ploidy level of hexaploid. It has undergone several successive rounds of genome polyploidy, and experienced an additional, more recent genome duplication event. More significantly, the dual reproduction modes, including gynogenesis and sexual reproduction, have been demonstrated to coexist in the polyploid gibel carp. This article reviews the genetic basis concerning polyploidy origin, clonal diversity and dual reproduction modes, and outlines the progress in new variety breeding and gene identification involved in the reproduction and early development. The data suggests that gibel carp are under an evolutionary trajectory of diploidization. As a novel evolutionary developmental (Evo-Devo) biology model, this work highlights future perspectives about the functional divergence of duplicated genes and the sexual origin of vertebrate animals.

“…auratus gibelio 两个亚种, 两者的分布区域大体上以长城为界 (Chen & Huang, 1982;Ren et al, 2002;Shen et al, 1997) (Chen & Huang, 1982;Ren et al, 2002;Shen et al, 1997) (Chen & Huang, 1982;Ren et al, 2002), 但《中国动物志·硬骨鱼纲·鲤形目·下卷》中记载其鳃耙数为 30~52 (Luo & Yue, 2000)。这可能是排版疏忽造成的, 因为该书的前期工作总结形成的《中国鲤科鱼类志》中记载其鳃耙数为 27~29 (Chen & Huang, 1982)。白鲫 (C. cuveri)分布范围较窄只限于日本列岛的部分水域, 该种鳃耙密而细长, 数目为 92~130, 据此特征可以与鲫属其他种或亚种区分 (Hosoya, 2002)。鲫(C. auratus)在东亚有广泛的地理分布 (Chen & Huang, 1982;Hosoya, 2002;Ren et al, 2002;Shen et al, 1997), 近年来更入侵到中亚和欧洲的部分水体中 (Jakovlić & Gui, 2011;Kalous et al, 2007;Tsoumani et al, 2006;Wheeler, 2000), 其生物学特性复杂，分类也最不完善。 (Gui, 2007;Gui & Zhou 2010), 有学者在研究中习惯将三倍体等同于银鲫 (Gui, 2007;Shen et al, 1997)。近年来日本学者也习惯将日本分布的多倍体鲫归为关东鲫(C. auratus langsdorfii) (Hosoya, 2002;Ohara et al, 1999Ohara et al, , 2000, 但是越来越多的研究发现三倍体鲫在线粒体谱系上更加接近于同域的二倍体 (Apalikova et al, 2008;Brykov et al, 2002;Murakami et al, 2001;Takada et al, 2010 …”

Abstract:The classification of Carassius has not been well established due to its great variability and wide distribution. Usually, Carassius is identified as three species: C. carassius, C. cuvieri and C. auratus, the latter including several subspecies, such as goldfish. Out of these subspecies, C. auratus gibelio have recently been thought of as a valid species of Carassius. In this study we collected the 5′end 651 bp segments of the mitochondrial cytochrome c oxidase I (COI) gene from 128 specimens, including C. carassius, C. cuvieri, C. auratus auratus, C. auratus gibelio and C. auratus langsdorfii. All three species of Carassius (C. carassius, C. cuvieri, C. auratus) were found to be valid, meanwhile genetic differentiation between the Eurasian C. auratus and Japanese C. auratus has reached a high level. However, several haplotypes were shared between C. auratus auratus and C. auratus gibelio. Consequently, C. auratus gibelio should be regarded as a subspecies of C. auratus rather than a valid species. Moreover, because both diploids and triploids exist in C. auratus auratus and C. auratus gibelio, ploidy level should not be used as criteria for the classification of species or subspecies in Carassius.
