The mucosal surfaces of fish play numerous roles including, but not limited to, protection
against pathogens, nutrient digestion and absorption, excretion of nitrogenous wastes and
osmotic regulation. During infection or disease, these surfaces act as the first line of defense,

mucosal surfaces in yellowtail kingfish displaying signs of gut inflammation, as well as …
