Mucosal organs exhibit distinct response signatures to hydrogen sulphide in Atlantic salmon (Salmo salar)

Mucosal organs exhibit distinct response signatures to hydrogen sulphide in Atlantic salmon (Salmo salar)

Since hydrogen sulfide (H2S) is regarded as an immunotoxicant, fish mucosal barriers may be affected by its presence in the water. The study Mucosal organs exhibit distinct response signatures to hydrogen sulphide in Atlantic salmon (Salmo salar) looked into how prolonged exposure to sub-lethal levels of H2S affected the Atlantic salmon’s (Salmo salar) mucosal defenses. For 12 days, fish were continuously exposed to two H2S concentrations. Fish that were not exposed were used as a control.

The research contributes to a better understanding of the interactions between H2S and Atlantic salmon,particularly at mucosal surfaces. The results of the study can be applied to risk assessment strategies for land-based Atlantic salmon farming.
