The cased fish. The classic British form is a skin mount in a glazed case with a painted backdrop, reeds and a modelled riverbed. The firm most associated with it is John Cooper & Sons of London, founded by John Cooper — a former watchmaker — in the 1830s, continued by his son after 1872 and trading as J. Cooper & Sons from about 1896 when the third generation joined. Their cases are recognised by bow fronts, gold line trim and gilt lettering, and the earliest ones from around 1840 are flat-fronted, with the bow front and wrapped glass coming later. Pike, chub, salmon, trout, tench, roach and rudd are the usual subjects.

Why the colour has to be painted. Fish colour comes from chromatophores — living pigment cells — and from structural reflectors in the skin. Both depend on tissue that is intact and hydrated. Drying destroys them, so every skin mount ever made, then and now, is repainted. The honest description of the craft is that the sculpture is the fish's and the colour is the taxidermist's, which is exactly why the reference photographs matter more than any other single step.

Skin mount versus replica. Modern trophy work is largely fibreglass replicas cast from a mould and painted to measurements and photographs — the fish is released alive. Replicas do not grease, do not shrink and do not attract insects, and for a protected or released fish they are the only lawful option. The skin mount survives where the specimen itself is the point: museum reference material, historical restoration, and cases where the actual animal matters more than the image of it.

Arsenic, and why it is not in this blueprint. Nineteenth-century taxidermy relied on arsenical soap, which is why antique mounts are handled with care in museums to this day. Borax does the same job of drying and deterring insects without the poison. The historical preparation is described in the literature and is deliberately not given here as a recipe.
