Composición y distribución de peces continentales en el sur de Quintana Roo, Península de Yucatán, México
Composition and distribution of the continental ichthyofauna were studied in southem Quintana Roo and adyacent areas of Campeche and Belize, southeastern Yucatan Peninsula, Mexico, on the basis of 69 sampled 10ca1ities, as welI as the published information and the fish collection carried out by the Zoology Museum at the Quintana Roo Research Center (MZ-CIQRO P). Fishing gear included 2- and 20-m-Iong seine nets, 1- and 3-m-wide throw nets, hook, spear, hand.nets, and traps; we recorded parameters such as temperature, salinity and conductivity, transparency, depth, dissolved oxygen, bottom type and riparian vegetation. Most of the sites were visited in the rainy and the dry SeasODS. The inventory of continental fishes of Quintana Roo includes 85 species, 55 detected in the southem zone. Twelve are recorded for the first time in continental waters of the state: Anchoa colonensis. A. parva. Rhamdia laticauda, Atherinella sp., Strongylura timucu. Diapterus auratus, Eugerres plumieri. Stegastes leucostictus. Rivulus tenuis .• Phallichthys fairweatheri. Xiphophorus helleri. and Stephanolepis hispidus. Ouster analysis allowed distinction of the following four local ichthyofaunas, sorted by decreasing distance to the coast: (1) Zohlaguna Plateau, sorne 250 masl, with relatively cool waters; (2) Hondo River and bordering water bodies, such as freshwater cenotes, wetlands, pools and creeks; (3) Center-Northeast Zone, including the brackish lalce systerns of Bacalar, Guerrero and Ubero, as well as the wetlands around the Bay of Chetumal and freshwater lakes such as Vallehermoso; and (4) Southem Caribbean coastal lagoons. where salinity varies regularly.
