“…While the systemic and mucosal antibody responses of fish appear to occur separately (1, 35-39, 42, 45, 48), the actual mechanisms and sites of cutaneous antibody induction, production, and secretion have yet to be determined (18,36,47). Antibodies detected in the mucus of the plaice (Pleuronectes platessa L.), ayu (Plectoglossus altivelis), sheepshead (Archosargus probatocephalus), and channel catfish are physically and immunologically identical to those isolated from the blood yet do not appear to arise by transduction (19,20,22,26,30,34). For example, experimental evidence from studies with the sheepshead (a common marine fish) showed that antibodies isolated from the blood, subsequently labeled with I 125 , and injected intravenously back into the same fish were not detected in the cutaneous mucus or bile (25).…”

“…The well-documented non-specific defence mechanisms (Fletcher 1982) and specific immune response of the fish host (St. Louis-Cormier et al 1984) could also influence resistance to monogenean invasion. Thus, a number of active non-specific substances such as proteases (Hjelmeland et al 1983), trypsin (Braun et al 1990), lysozyme (Lie et al 1989) and specific antibodies (Fletcher & Grant 1969, Bradshaw et al 1971, Lobb & Clem 1981, St. Louis-Cormier et al 1984 have been detected in fish mucus. As both the resistance of brown trout to ectoparasite invasion and the epidermis change seasonally (Pickering 1977, Pickering & Christie 1980 and the composition of fish mucus varies during a Gyrodactylus sp.…”

The susceptibility of 4 salmonids [rainbow trout Oncorhynchus rnykiss, brown trout Salmo trutta, a Baltic (Iijoki) and an Atlantic (Conon) strain of Salmo salar] to infect~on with a Danish isolate of Gyrodactylus derjavinj was tested in the laboratory (12 to 13°C). Initial parasite attachment numbers did not differ between species, but parasite populations increased significantly faster and to a higher level in rainbow trout compared to the other salmonids, with S. trutta exhibiting an intermediate position. The 2 strains of S. salar became only slightly infected during the following weeks despite a heavy infection pressure. The parasites' selection of microhabitat on the hosts also differed between species and changed over time on the same host species. The tail fin was the preferred site in all salmonids although the pectoral, pelvic and anal fins were important sites in the initial period of the 6 wk investigation. It is notable that the cornea1 surface, especially in the Baltic salmon, became increasingly more heavily infected in the later stages of the infection period. Explanations for the differing degrees of susceptibility are suggested and some of these were investigated. Lysozyme activity in the fin epithelia and the density of mucous cells in the fins from the hosts were compared. Marked lysozyme activity was detected in tail fins from the 4 salmonids, but the activity was not associated with host resistance to infection. In contrast, the density of superficial mucous cells, which showed regional variation on the tail fins, was negatively correlated with susceptibility to infection. Thus, fish with high density of epithelia1 mucous cells showed the lowest susceptibility to infection, and this finding is discussed in relation to host resistance.

“…The continuous flow of water through the opercular chambers which provides an exchange of oxygen probably aggravates the risk of ddditional exposure of the gills to the ambient pollutants. The continuous secretion of slime by the gills and by the inner opercular lining might provide an important safety coating for the gills since slime is known to act as a lubricant and to provide mechanical protection, has an osmoregulatory function, prevents colonization of parasites, f.ungi, and bacteria, and contains various types of compounds that can support several chemical and im~nunological reactions (Van Oosten 1957, Fletcher & Grant 1969, Rosen & Cornford 1971, Cameron & Endean 1973, Pickering 1974). According to Arillo & Melodia (1990), fish mucus constitutes a kind of barrier between a fish and its environment and some mucus components may have a de-toxifying function counteracting ambient toxins.…”

Acute toxicity of 2 g 1.' (LCSO) ammonium sulphate on the outer and inner epithelial linings of the operculum of the air-breathing catfish Heteropneustes fossills (Bloch) at different intervals of exposure was studied using histochemical techniques. The inner and outer ep~thelial linings showed different responses to the corrosive action of the inorganic fertilizer The outer epithelial lining exhibited massive and quicker damage due to necrosls and sloughing of its surface epithelial cells along with degeneration and disappearance of the club cells. Simultaneous regeneration of various cellular elements of the epidermis was also observed There were comparatively very few necrotic changes in the cellular constituents of the inner epithelial lining The alterations observed include hyperplasia of the epithelial cells (which showed accumulation of glycogen granules) and periodic increases followed by decreases in the density and size of the goblet mucous cells.
