This study aims to determine the physiological effects of sub-lethal concentrations of nitrite in the olfactory function of goldfish ( Carassius auratus ). Thus, goldfish were exposed to 6 different NO 2 concentrations (1000 mM, 500 mM, 300 mM, 100 mM, 10 mM and 0 mM.) for 72 h. At ...
Abrupt pH changes from hatchery to pond water may affect survival of Goldfish Carassius auratus fry after stocking. A total of 12 triplicate pH treatments ranging from 3.57 to 11.50 were used to assess a gradient of abrupt pH changes on survival of 3-d posthatch (dph) Goldfish fry in ...
a year. The goldfish and related species have evolved to thrive in productive waters where visibility is poor. Reproduction is highly seasonal withoocytegrowth andvitellogenesis(yolk deposition) occurring in the winter after which females undergo final maturation (resumption of meiosis) and then ovulate...
We investigated the effects of blue light spectra on stress in the retinas of goldfish, using a blue (460nm) light-emitting diode (LED) at three intensities (0.5, 1.0, and 1.5W/m 2 ). The experiment was conducted for 4weeks, and sampling was performed at intervals of 1week. We ...
The female then chooses a male with which to spawn; it is likely that this choice is made at least in part on the smell of his urine, including the perceived concentration of pheromone. After spawning, the female picks up the fertilized eggs in her mouth and moves away (often actively ...
After 18 hours of oocyte storage, the fertilization rates totally lost and no viable embryos were detected. Relative abundance of mRNAs during in vitro oocyte ageing. The mRNA abundance of 13 specific transcripts were determined and compared in different aged oocytes, usibg b-actin as the ...
Effects of waterborne selenium exposure on the antioxidant and immunological activity in the goldfish (Carassius auratus). Mol. Cell. Toxicol. 9, 365-373.Choi YJ, Kim NN, Shin HS, Park MS, Kil G-S, Choi CY. 2013. Effects of waterborne selenium exposure on the antioxidant and immunological...
The Effect of Caffeine on Goldfish Metabolism Introduction Metabolism is the sum of all anabolic and catabolic reactions within a living organism. The energy required to perform these reactions is provided by oxygen in the form of ATP, therefore the oxygen consumption rate can be measured to determ...
Hormone changes during ovulation and effects of steroid hormones on plasma gonadotropin levels and ovulation in goldfish. General and Comparative Endocrinology 67: 24–32.Kobayashi, M., Aida, K., Hanyu, I., 1987. Hormone changes during ovulation and effects of steroid hormones on plasma ...
The expression and activity of the antioxidant enzymes and levels of H 2 O 2 , LPO, AspAT/AlaAT, and melatonin were significantly higher after the fish were exposed to low-/high-water temperature environments. Furthermore, in green and blue lights, the expression of antioxidant enzymes and ...
