“…Crucian carp ( Carassius auratus ) is a genus of Carassius in the family Cyprinidae ( Xiao et al., 2011 ). More than 1000 years ago, crucian carp was domesticated in China and introduced into Europe and most parts of the world since the 17th century ( Chen, 1956 ; Balon, 2004 ; Gao et al., 2012 ; Podlesnykh et al., 2015 ). It has the advantages of fast growth, short reproductive cycle, tender meat and high nutritional value ( Liao et al., 2013 ).…”

Crucian carp (Carassius auratus) is one of the major freshwater species and is also a common food fish in China. Recently, Carassius auratus herpesvirus (CaHV) could induce fatal viral disease with high mortality of crucian carp, which had caused huge economic losses. In this study, we described a rapid and simple recombinase-aid amplification (RAA) assay coupled with lateral flow dipstick (LFD), which could achieve sensitive diagnosis of tumor necrosis factor receptor (TNFR) of CaHV within 35 min at 40°C. Our RAA-LFD method had a satisfactory detection limit of 100 gene copies per reaction, which was 100-fold more sensitive than traditional PCR. In addition, no cross-reaction was observed with other viral pathogens, including koi herpesvirus (KHV), cyprinid herpesvirus 2 (CyHV-2), infectious hematopoietic necrosis virus (IHNV), spring viremia of carp virus (SVCV) and grass carp reovirus (GCRV). Furthermore, the overall cost of the method was cut in half compared to previous studies. In conclusion, RAA-LFD assay is therefore, a promising alternative for point-of-care testing (POCT) of CaHV, which is feasible and of certain value in application of aquatic disease control.

“…Ornamental fish keeping in its present form was made possible by the beginning of air transport, permitting the utilization of fish in distant parts of the world and their transportation to markets in developed countries nowadays (Malik et al, 2014). So, the fish must not only be attentiongrabbing but also healthy enough to resist long air transportation (Podlesnykh et al, 2015). Import and export of ornamental fish are approximately handling up to one and a half billion fishes.…”

This study observed the captive culture of Carassius auratus and Cyprinus carpio in the Potohar region, Punjab, Pakistan. Captive culturing of both species was conducted up to one-month post hatchlings. The sample size was 180 (90 goldfish and 90 koi carp) and kept in cemented raceways under optimum conditions. The study period was from October 2019 to April 2020. The natural breeding season for Carassius auratus and Cyprinus carpio was from 25th January to 5th February and the end of February to 11th March, respectively. The induced breeding duration for goldfish and koi carp was from 6th to 25th February and for koi carp from 12th to 30th March, respectively. For artificial breeding, the synthetic hormone Ovaprim C was injected intra-peritoneally at 0.5 ml/kg and 0.1 ml/kg body weight of females and males, respectively. Both the species were fed a 30% crude protein diet. Hydrilla plants were used for the adhesion of eggs. The female to male ratio was 2:3. Approximately 4500 to 5000 eggs of goldfish and 17000 to 18000 eggs of koi carp were laid. Fertilization, hatching, and survival rates observed for both were approximately 74%, 57% and 42.5%, respectively.

“…An obvious difference between GF and RCC is that GF has distinct split double tails (twin tail), whereas RCC does not. Although some studies have suggested that GF evolved from crucian carp ( Podlesnykh et al, 2015 ), the direct evidence of its evolutionary pathway is lacking. Hybridization promotes species formation and the adaptive radiation of animals and plants ( Mallet, 2007 ).…”

The Formation of the Goldfish-Like Fish Derived From Hybridization of Female Koi Carp × Male Blunt Snout Bream

et al. 2018

Goldfish (Carassius auratus var., GF; 2n = 100) is the most popular ornamental fish in the world. It is assumed that GF evolved from red crucian carp (C. auratus red var., RCC; 2n = 100). However, this hypothesis lacks direct evidence. Furthermore, our knowledge of the role of hybridization in the formation of new species is sparse. In this study, goldfish-like fish with twin tails (GF-L; 2n = 100) was produced by self-mating red crucian carp-like fish (RCC-L; 2n = 100) derived from the distant crossing of koi carp (Cyprinus carpio haematopterus, KOC; 2n = 100; ♀) with blunt snout bream (Megalobrama amblycephala, BSB; 2n = 48; ♂). The phenotypes and genotypes of GF-L and RCC-L were very similar to those of GF and RCC, respectively. Microsatellite DNA and 5S rDNA analyses revealed that GF-L and RCC-L were closely related to GF and RCC, respectively. The presence of a twin tail of GF-L was related to a base mutation in chordinA from G in RCC-L to T in GF-L, indicating that the lineage of RCC-L and GF-L can be used to study gene variation and function. The sequences of 5S rDNA in GF-L and RCC-L were mapped to the genomes of CC and BSB, which revealed that the average similarities of both GF-L and RCC-L to CC were obviously higher than those to BSB, supporting that the genomes of both RCC-L and GF-L were mainly inherited from KOC. GF-L and RCC-L were homodiploids that were mainly derived from the genome of KOC with some DNA fragments from BSB. The reproductive traits of GF-L and RCC-L were quite different from those of their parents, but were the same as those of GF and RCC. RCC-L easily diversified into GF-L, suggesting that RCC and GF evolved within the same period in their evolutionary pathway. This study provided direct evidence of the KOC–RCC–GF evolutionary pathway that was triggered by distant hybridization, which had important significance in evolutionary biology and genetic breeding.
