An Inactive Thyroid Gland in Carassius auratus [PDF]
Nature, 1956 Carassius auratus has been subjected to prolonged artificial selection which has established several unusual features. Among these is the inactivity of the thyroid gland. This gland consists of follicles scattered along the anterior region of the ventral aorta; the follicles are typically inactive, with squamous epithelium and abundant colloid.

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

Gill Sphaerosporosis in Goldfish (Carassius auratus) [PDF]
Journal of Wildlife Diseases, 1990 Infections caused by a Sphaerospora sp. resembling S. chinensis are reported for the first time in goldfish (Carassius auratus) from North America. The myxosporean was found in the respiratory epithelium of the gill of pond-reared fish. Spores from stained tissue sections were spherical with an equal mean length and width of 6.3 microns.

Isolation of Shewanella putrefaciens from Goldfish (Carassius auratus auratus) [PDF]
Israeli Journal of Aquaculture - Bamidgeh, 2014 In the present study, the etiological agent that caused mortality in goldfish at an aquarium company located in Bursa in northwestern Turkey was identified. Diseased fish were lethargic, displaying a loss of appetite, ascites, and exophthalmia. Internal examination revealed that the kidney was surrounded by exudate and that the spleen and liver were ...

Distance estimation in the Goldfish (Carassius auratus)
Proceedings of the Royal Society B: Biological Sciences, 2022 AbstractNeurophysiological advances have given us exciting insights into the systems responsible for spatial mapping in mammals. However, we are still lacking information on the evolution of these systems and whether the underlying mechanisms identified are universal across phyla, or specific to the species studied.

PCR survey of hox genes in the goldfish Carassius auratus auratus [PDF]
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2006 AbstractA tetraploidization event took place in the cyprinid lineage leading to goldfishes about 15 million years ago. A PCR survey for Hox genes in the goldfish Carassius auratus auratus (Actinopterygii: Cyprinidae) was performed to assess the consequences of this genome duplication.
