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...

Membrane immunoglobulin (Ig) of splenocytes and thymocytes of the goldfish, Carassius auratus, was demonstrated by indirect fluorescent-antibody techniques. Observations on shedding and resynthesis indicated that the thymocyte Ig was endogenously produced. The lymphocyte surface proteins were radioiodinated using the lactoperoxidase-catalyzed reaction, and the labeled Ig molecules were isolated...

Citrobacter freundii is a zoonotic pathogen that causes skin injuries and high mortality rates in fish. This study aims to determine the presence of C. antibiotic susceptibility 50 goldfish (Carassius auratus) wounds with local bleeding between ages 8–18 months three regions (A, B, C) located West Turkey. (22/50; 44%) strains were isolated from wound swab samples by phenotypic genotypic methods...

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...

Swimbladder of the crucian carp, Carassius auratus, was found to be better as a vegetalizing tissue than other tissues, such as guinea-pig bone marrow, when presumptive ectoderm of Triturus gastrulae was used as reacting tissue. Swimbladder usually induced assemblies of highly organized mesodermal tissues, such as notochord, somites and pronephric tubules, some of which were covered by mesoderm...
