Much of the information on UV-B-affected fish has come from laboratory studies. For example, Lahontan cutthroat trout (Oncorhynchus clarki henshawi)... 

Figure 6. (A) Skin of cuttroat trout Oncorhynchus clarki henshawi) not exposed to UV. Mucous cells (open arrows) are scattered throughout the epidermis. Melanocytes (filled arrows) are seen on either side of the stratum compactum. Bar equals 50 /um. (B) Skin after 72 h of UV exposure. Note epidermis is lifted off the basement membrane, and the area between the dermis and epidermis is filled with necrotic cells, inflammatory cells, and exudates. A few sunburn cells (arrows) with glassy, pyknotic nuclei and perinuclear halos can be seen. Bar equals 19 fxm. [From Blazer et al. 15.]...

With terrestrial animals, vaccination is regarded as the primary means of disease control where application is often by injection and protection reflects antibody levels, but the numbers of individuals needed to be vaccinated is comparatively low compared with the populations in intensive aquaculture facilities. The flrst bacterial fish vaccine was described by Duff (1942), who used chloroform-inactivated cells of Aeromonas salmonicida to protect cutthroat trout Salmo clarki) against furunculosis. There is evidence that interest in vaccines declined with the availability and effectiveness of antibiotics, but the subsequent development and spread of antibiotic-resistance rekindled research in vaccinology. Nevertheless despite the increasing number of serious fish pathogens, only a comparatively few commercial products have entered the market place. Moreover, interest has focused on less than half of aU the bacteria taxa described as fish pathogens.
