Photography has played an increasingly important role in fish taxonomy, systematic studies, aquarium literature, field guides, and fisheries literature. Images are a particularly important aid in taxonomy for recording pigmentation patterns as well as meristic and morphometric characteristics. Photographs have also been used for estimating fish weights and lengths (Baugh 1982).
Several techniques have been developed for photographing preserved fish specimens (Randall 1961; Emery and Winterbottom 1980; Flescher 1983; Holm 1989). The most popular technique (Emery and Winterbottom 1980) involves the use of an inclined glass plate inside an aquarium to stabilize the specimen and artificial lighting. This setup has two disadvantages; the imaging of specimens is slow, and small fish specimens are sometimes difficult to position between the inclined plate and the aquarium glass.
