- Abstract:
- ... The aim of this study was to provide a reference value for the safe regulation and control of ammonia nitrogen in the aquaculture of Sepia pharaonis. The effects of acute and chronic toxicity of ammonia on the cuttlefish, S. pharaonis, were tested experimentally using juvenile S. pharaonis. The results showed that the half‐lethal concentration (LC₅₀) values of ammonia nitrogen in juvenile S. phara ...

- Abstract:
- ... The effect of salinity on the embryonic development of Sepia pharaonis eggs was tested experimentally using S. pharaonis embryos at various developmental stages. The hatching rate, incubation period, hatching period, wet weight of hatchling cuttlefish, and yolk utilization efficiency ratio were quantified at salinities of 18, 21, 24, 27, 30, 33, and 36. These variables were significantly affected ...

- Abstract:
- ... To investigate the ammonia detoxification pathways of the cuttlefish, Sepia pharaonis, the effects of environmental ammonia nitrogen exposure (control, 1, 3, and 6 mg/L) on nitrogen metabolism were quantified in the hemolymph, liver, and gills. The levels of glutamine synthetase, glutamate dehydrogenase, and arginase activities and ammonia, glutamine, and urea concentrations in the hemolymph, live ...
