Morphology of the Intestine of the Goldfish (Carassius Auratus) [PDF]

Bijdragen tot de Dierkunde, 1976
A survey of the structures of the intestine of the Goldfish is given. Several morphological techniques have been used. Special attention has been paid to those characteristics of this organ that may be of importance to physiologists working with the same material, with emphasis on cell-to-cell contact in the mucosal epithelium, which appeared to be ...

The First Record of Argulus Foliacesus (Crustacea: Branchiura) Infesta­tion on Lionhead Goldfish (Carassius Auratus) in Iran [PDF]

Iranian Journal of Parasitology, 2010
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.

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).

Kidney activity increases in copper exposed goldfish ( Carassius auratus auratus ) [PDF]

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2016
In the present study, the effect of copper was examined in the common goldfish (Carassius auratus auratus). Fish were fasted and exposed to either a high (0.84μM), a low (0.34μM) or a control copper concentration (0.05μM) for 1 and 7days. Swimming performance was not affected by either fasting or copper exposure. Food deprivation alone had no effect on

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.

Complete Genome and Molecular Characterization of a New Cyprinid Herpesvirus 2 (CyHV-2) SH-01 Strain Isolated from Cultured Crucian Carp

Viruses, 2022
Cyprinid herpesvirus 2 (CyHV-2) is a causative factor of herpesviral hematopoietic necrosis (HVHN) in farmed crucian carp (Carassius carassius) and goldfish (Carassius auratus). In this study, we analyzed the genomic characteristics of a new strain, CyHV-

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.

Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

Journal of Animal Ecology, EarlyView.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

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 ...
