In order to evaluate the eco-toxicological effects of Roundup on Carassius auratus (C. auratus), fish were exposed to 32 μg/L Roundup, isopropylamine salt of glyphosate (G.I.S) and polyoxyethylene amine (POEA) over different periods (0.5, 1, 3, 7 and 14 d). Hydroxyl radical (·OH), malondialdehyde (MDA) and acetylcholinesterase (AChE) in liver were detected in this study. Results showed that the...

Edwardsiella tarda is an intracellular pathogen that causes edwardsiellosis in fish. Although cell-mediated immunity and innate immunity play a major role in protection against intracellular bacterial infection in mammals, their importance in protecting fish against E. tarda infection remain unclear. In this study, we examined cell-mediated and humoral immune responses in ginbuna crucian carp (...

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...
