p-Nitrophenol (PNP) is one type of environmental pollutant, which is difficult to degrade and soluble in water. To investigate the effects of PNP on economically important marine fish species, we subjected Larimichthys crocea juvenile to five different concentrations of PNP for 96 h, and the semi-lethal concentration (LC50) was 6.218 mg/L.

To investigate how bile salts affect olfactory signal transduction in large yellow croaker (), deep sequencing of olfactory epithelium was conducted to analyse olfactory-related genes in olfactory transduction. Sodium cholates (SAS) have typical bile salt chemical structures, hence we used four different concentrations of SAS to stimulate , and the fish displayed a significant behavioural preference for 0.

Formaldehyde can effectively control ectoparasites in silver pomfret (Pampus argenteus). However, there is limited information on the effects of formaldehyde treatment at a molecular level in fishes. In the present study, transcriptome profiling was conducted to investigate the effects of formaldehyde treatment (80 mg/L, bath for 1 h every day for three consecutive days) on the liver and kidney tissues of silver pomfret.

To determine the optimal anesthetic, we investigated the physiological response of crucian carp (Carassius auratus) treated with three different anti-stress treatments: MS-222, eugenol and percussive stunning. Stress responses were evaluated by analyzing serum cortisol level and gene expression in blood.
