C1q-like is a significant maternal factor of TNF/C1q super-family, and the abundant protein has been observed in both mature eggs of Carassius auratus and Carassius auratus gibelio, but its biological function in early embryo development has remained unclear. In this study, we firstly revealed a high level of maternal C1q-like transcript existence only in mature eggs of Carassius auratus, where...

Carassius auratus var. pingxiangnensis is a natural triploid crucian carp mutant. In order to understand its placement and genetic background at the gene level, the characteristics of mitochondrial DNA sequences and phylogenetic relationship were examined. The results showed that the mitochondrial DNA is a circular double-stranded DNA molecule that is 16,576 bp in length with 13 protein-coding ...

The Carassius auratus complex in natural populations includes diploid triploid and polyploidy individuals. Diploid individuals belong to the species Carassius auratus whereas triploid and polyploidy individuals are from the subspecies Carassius auratus gibelio. Triploid individuals are all female and reproduce clonally by gynogenesis. Therefore the Carassius auratus complex is an ideal system f...

Six commonly freshwater ornamental fish, namely Poecilia rediculata (guppy); Poecilia sphenops (black molly); Cichlosoma sp. (Cichlidae); Xiphophorus maculatus (platy); Carassius auratus (goldfish) and Symphisodon discus (discus) were examined for parasites during a four years study (19982002) in Turkey. The parasites species found included: Ichthyobodo sp., Ichthyophthirius multifiliis, Chilod...

Argulus foliaceus (Crustacea: Branchiura), or the fish louse, is an ectoparasite of the skin or gill of the fresh water fish species. Clinical signs in infected fish include scratching on aquarium walls, erratic swimming, and poor growth. It causes pathological changes due to direct tissue damage and secondary infections. In the present study, lionhead goldfish (Carassius auratus), taken from a...

BACKGROUND Goldfish, Carassius auratus, have experienced strong anthropogenic selection during their evolutionary history, generating a tremendous extent of morphological variation relative to that in native Carassius. To locate the geographic origin of goldfish, we analyzed nucleotide sequences from part of the control region (CR) and the entire cytochrome b (Cytb) mitochondrial DNA genes for ...
