Isolation of microsatellites in the bighead catfish, Clarias macrocephalus and cross-amplification in selected Clarias species.

The present study documents the isolation of eight polymorphic microsatellite markers from the bighead catfish, Clarias macrocephalus and cross-amplification in two other catfish species. The number of alleles per locus in C. macrocephalus ranged from 2 to 21.
