Organization and expression analysis of 5S and 45S ribosomal DNA clusters in autotetraploid Carassius auratus

BMC Ecology and Evolution, 2021
Background Autotetraploid Carassius auratus (4n = 200, RRRR) (abbreviated as 4nRR) is derived from whole genome duplication of Carassius auratus red var. (2n = 100, RR) (abbreviated as RCC).

The Effect of Temperature on Trophic Discrimination of Stable Isotopes (13C and 15N) and Biokinetics in Common Carp (Cyprinus carpio, L. 1758)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Stable isotope analysis (SIA) provides essential information toward a better understanding of trophic ecology. However, the interpretation of SIA results relies on assumptions about the trophic discrimination factor (TDF), which aims to improve the accuracy but may lead to bias.

The use of the ethanol pathway in goldfish Carassius auratus (L.) following anoxia [PDF]

, 2001
Goldfish (Carassius auratus) were subjected, for a period of 6 weeks, to 2h progressive hypoxia followed by 6h anoxia in closed respirometers at 15 degree C.

The valvula cerebelli of the spiny eel, Macrognathus aculeatus, receives primary lateral-line afferents from the rostrum of the upper jaw [PDF]

, 1991
In the spiny eel, Macrognathus aculeatus, anterodorsal and (to a lesser degree) anteroventral lateralline nerves project massively to the granular layer of the valvula cerebelli, throughout its rostrocaudal extent.

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state

Journal of Animal Ecology, EarlyView.
The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

Genome Expansion of ZPB1(a) and ZPC1(a) in Basal Species or Liver Expression of ZPB1a and ZPC1aa in Advanced Species, Two Different Strategies to Ensure Sufficient ZP Synthesis in Teleosts

Integrative Zoology, EarlyView.
We found that teleosts employed two different strategies to ensure sufficient ZP (zona pellucida) synthesis: expansion of ZPB1(a) and ZPC1(a) in basal species or liver expression of ZPB1a and ZPC1aa in advanced species. The N‐terminus of expanded ZPB1(a) or ZPC1(a) and liver‐expressed ZPB1a contains repeated units or low‐complexity regions to form ...

Fertilization and growth performance in reciprocal hybrids of Dianchi golden-line barbel (Sinocyclocheilus grahami) and domestic common carp (Cyprinus carpio) and crucian carp (Carassius auratus)

Aquaculture Reports, 2021
Hybridization has been successfully achieved using Dianchi golden-line barbel (Sinocyclocheilus grahami) and barbless carp (Cyprinus pellegrini) as parental species. However, little is known about the crossbreeding feasibility of S.
