Abstract
We describe a method of preparing pectoral spines from juvenile channel catfish Ictalurus punctatus and other ictalurid species that allows easy sectioning and aging. The method uses marine epoxy poured into molds that enables the encased spine to be held firmly for sectioning with a saw. The technique costs less than US$10 to prepare up to 500 spines and takes only a few hours
