Vargas, López, Salas, and Thinus-Blanc showed that goldfish (Carassius auratus) can use both geometric and featural cues in relocating a target corner in a rectangular enclosure. When featural cues (arrangement of striped walls) were put in conflict with geometric cues, results differed according to target location during training. Vargas, López, et al. explained the results of their cue confli...

Length-weight relationships (L-WRs) and condition factors were estimated for eight exotic fish species, including Oreochromis niloticus, Coptodon zillii, Carassius auratus, C. gibelio, Pseudorasbora parva, Gambusia holbrooki, Lepomis gibbosus, Oncorhynchus mykiss from 10 basins of Turkish inland waters. A total 1958 specimens sampled in the years 2014, 2017, 2018, 2019 29 populations their LWRs...

Mycobacteriosis is a chronic disease of freshwater and marine fish. In the present study, Mycobacterium fortuitum from a diseased gold fish, Carassius auratus was isolated and identified by biochemical and molecular (PCR) method. The isolate was found to be resistant to rifampicin, isoniazid, pyrazinamide and ethambutol and myoconda® a nanodrug combination of rifampicin, clarithromycin and clof...

To estimate the dietary iron requirement of common goldfish, Carassius auratus (Linnaeus, 1758), eight isoproteinous diets containing graded levels of dietary iron (FeSO4.7H2O) ranging 34.27-537.14 mg/kg were fed to triplicate groups of C. auratus fry in glass tanks. The rearing medium was groundwater passed through a reverse osmosis water treatment unit. Fish were fed 3% of their body weight p...

This study aimed to investigate the morphology and reconstruct the phylogenetic relationships of Centrocestus formosanus originating from 5 species of freshwater fish, i.e., Esomus metallicus, Puntius brevis, Anabas testudineus, Parambassis siamensis, and Carassius auratus, in Chiang Mai province, Thailand. Sequence-related amplified polymorphism (SRAP) and phylogeny based on internal transcrib...

The effects of concentration (5, 50, and 500 microg/L) and duration (24, 48 h) of exposure to carbofuran, a carbamate insecticide, were assessed on brain catecholamine (norepinephrine [NE] and dopamine), plasma glucose, and hepatic glycogen contents and behavioral activities of goldfish (Carassius auratus). After 24 h of exposure to 50 and 500 microg/L, the level of NE was increased in the olfa...
