Given that the gill respiratory epithelium is in direct contact with the external environment and physiological stress-inducing factors, and has a large surface area, poor quality of water (Mallatt, 1985; Hinton & Lauren, 1990), irritating toxic agents, infectious agents and the presence of parasites (Pavanelli et al., 2004) lead to functional impairment of the filaments and gill lamellae.
