We have constructed the first linkage map for walking catfish, Clarias macrocephalus, using amplified fragment length polymorphism (AFLP) markers. Forty-seven primer combinations were used to amplify DNA samples of a female C. macrocephalus and 79 haploid embryos. The AFLP map consists of 134 loci placed into 31 linkage groups, with 12 loci remaining unlinked. The number of markers per linkage group varies from 3 to 14. The map spans an estimated 2037.4 Kosambi cM, with an average spacing of 17.07 cM. This linkage map will provide the basis for a high-resolution map for walking catfish.
