So, what’s a fish cast? Fish are particularly difficult creatures to preserve. Fish taxidermy is tricky as even a freshly dead specimen rapidly loses it colour and can quickly start to decay. Fish skin is thin and tears easily and obtaining the work of an experienced fish taxidermist is very expensive while fluid preservation involves the use of chemicals which alter the skin colouration.
Modelling or casting is often chosen as an alternative way to represent the animal rather than using the actual fish skin as taxidermy does. A cast now might be made using a resin but historically plaster has been used. Then comes the clever bit, accurate painting of the cast to appear like the living animal.
