The haplochromine cichlid fishes inhabiting Lake Victoria in East Africa are of great interest to evolutionary biologists. We have isolated and optimized six tetranucleotide and a single dinucleotide locus from a hybrid of the haplochromine cichlid fishes, Pundamilia pundamilia and P. nyererei. Characterization in 18 individuals of P. nyererei from a single wild population revealed between six and 18 alleles per locus, with expected heterozygosity ranging from 0.68 to 0.94. These loci will prove useful for investigations of population structure, and elucidating relationships between closely related species. An additional 26 unoptimized loci have been deposited with GenBank and the MEN database. [ABSTRACT FROM AUTHOR]

The taxonomic status of the Atlantic and Mediterranean poor cod is a controversial issue. Here we present 10 microsatellite loci from poor cod Trisopterus minutus (L), which have been tested across 10 populations of poor cod. Most loci are highly polymorphic with 7-65 alleles, with one exception, the Tmssr two loci. In poor cod it is a compound microsatellite exhibiting extensive allelic variation. These markers have utility for the two subspecies of poor cod and possible utility for the Trisopterus genus. They may also provide a strong tool for detailed population studies in all gadoids.
