Avoidance of fenitrothion by goldfish (Carassius auratus)

Bulletin of Environmental Contamination and Toxicology, 1975
Goldfish (Carassius auratus) avoided water containing the pesticide fenitrothion. The response was graded over the tested concentration range of 5 orders of magnitude, with a threshold around 10 mug/1, equivalent to 3.5 times 10-minus 8 M.

The chimeric genes in the hybrid lineage of Carassius auratus cuvieri (♀)×Carassius auratus red var. (♂)

Science China Life Sciences, 2018
Hybridization can combine the genomes of different strains or species, which leads to changes of genotype and phenotype in the hybrids. In this study, we aimed to investigate the genetic variations of hybrids (WR-F1 and WR-F2) derived from the intraspecific hybridization of white crucian carp (Carassius auratus cuvieri, WCC, ♀) and red crucian carp ...

HISTOLOGICAL CHANGES IN EXPERIMENTAL EXOPHTHALMOS OF CARASSIUS AURATUS

Acta Endocrinologica, 1963
ABSTRACT Carassius auratus were injected with pituitary exophthalmos-producing substance and the subsequent histological changes studied. Oedema, infiltration of macrophages in the retrobulbar area, muscle swelling and splitting, and increase of mucinous substance were noted. Since such changes have been reported for exophthalmic human patients

Melatonin signal transduction in the goldfish, Carassius auratus

Neuroscience & Biobehavioral Reviews, 1994
Generation and reception of melatonin signals in the goldfish, Carassius auratus, are reviewed. The photoreceptive pineal gland of the goldfish generates circulating melatonin rhythms according to a given photoperiod under light-dark cycles and in a circadian manner under continuous dark conditions. Melatonin is also produced in the retina in a similar

Serotonin in the brain of the goldfish, Carassius auratus

Cell and Tissue Research, 1983
The distribution of immunoreactive serotonin (5-HT) was investigated in the brain and pituitary gland of the goldfish with the use of indirect immunofluorescence technique. Immunoreactive cerebrospinal fluid-contacting neurons were found in the nucleus recessus lateralis and in the nucleus recessus posterioris of the hypothalamus.

Metabolism of14C-heptachlor in goldfish (Carassius auratus)

Archives of Environmental Contamination and Toxicology, 1979
Goldfish injected with14C-heptachlor (38.2 μg/44 g fish) eliminated about 18% of the dose in 10 days. Analyses of the fish at the end of 10 days revealed the presence of five compounds of which 91.2% was unchanged heptachlor and the remainder was heptachlor epoxide (5.4%), 1-hydroxychlordene (1.0%), 1-hydroxy-2,3-epoxychlordene (1.1%) and a conjugate ...

Ocular Melatonin Rhythms in the Goldfish, Carassius auratus

Journal of Biological Rhythms, 1997
Ocular melatonin rhythms in the goldfish were studied and compared to those in the pineal organ and plasma. Under light:dark (LD) of 12 h light:12 h dark, melatonin contents in the eye as well as the pineal organ and plasma exhibited clear day-night changes with higher levels at mid-dark than at mid-light.

Mitochondria of Goldfish, Carassius auratus

Nature, 1960
THE metabolism of mitochondria of poikilotherms acclimatized at different temperatures has not been studied, though such studies have been made on rats1,2. The mechanisms of adaptation to cold and warm temperatures in a poikilotherm may be different from those of a homoitherm due to the presence of a temperature-regulating centre in the latter.

Leptospira Infection in the Gold Fish (Carassius auratus)

Nature, 1962
THE important role of waterholes, rice fields, swamps, slow-moving streams and sewers in the epidemiology of human and animal leptospirosis has been established1–3. Wild animals and migratory birds, present in surrounding areas, have been found to be infected and have been implicated in the dissemination of the disease4–7.

Genetic Diversity in Crucian Carp (Carassius auratus)

Biochemical Genetics, 1999
A survey of restriction fragment polymorphism in mitochondrial DNA of three subspecies of Carassius auratus throughout four provinces in China was undertaken using 17 restriction enzymes. Two carp, Cyprinus carpio rubbrofuscus and Cyprinus carpio carpio, were included as the outgroup.
