A fragment of the mitochondrial cyt b gene and one from the nuclear beta-actin gene were sequenced. The results support recognition of 3 ESU’s distributed as follows: 1) Sado River, 2) the Tagus River basin and 3 independent nearby coastal rivers (collectively named ‘‘West’’) and 3) Lagoa de Albufeira, a small coastal lagoon between Tagus and Sado basins.engPhylogeographyPortugalCritically endangered speciesEndemic fishjournal article
