Skin lesions in the tail of the spiny dogfish, Squalus acanthias L

Abstract

There are numerous reports of diseases and lesions of the major organs of a wide spectrum of bony fishes. By contrast, very few cases have been reported from elasmobranchs. This lack of information may reflect the fact that commercial exploitation of elasmobranch populations has been limited, although for several decades there have been fisheries for the spiny dogfish, Squalus acanthias L., in European waters. In both cases, many thousands of spiny dogfish have been sampled for population analysis. Further, the spiny dogfish has been dissected in senior biology courses in the UK for about 30 years and probably 5000 students take these courses annually. It is remarkable, with these numbers dissected, that so few lesions have been recorded. During the summer of 1980, whilst working at the Mount Desert Island Biological Laboratory, Maine, researchers sampled a large spiny dogfish which had a prominently engorged tail with numerous skin lesions. The fish was a mature female 100 cm long, weighing 6.5 kg, which was carrying 16 embryos in their second year of development. The dogfish was also remarkable in that one of the embryos had a marked developmental abnormality, its spinal column being severely twisted. Developmental damage appears to be unusual  More>>
