A silver impregnation technique to demonstrate muscle-bone-cartilage relationships in fishes

A modification of the Winkelmann and Schmitt (1957) technique originally designed to investigate patterns of peripheral nervous innervation is given for demonstration of developing bone growth centers and associated muscle origins and insertions in larval and small fishes. This technique offers a simpler and faster way of obtaining such ontogenetic information than the standard method of double staining with alizarin red S and Alcian blue followed by clearing with potassium hydroxide. Muscles also stain, facilitating the location of their origins and insertions.
