Lerma River
The Lerma River () is Mexico's second longest river. It is a river in west-central Mexico that begins in Mexican Plateau at an altitude over above sea level, and ends where it empties into Lake Chapala, Mexico's largest lake, near Guadalajara, Jalisco. Lake Chapala is also the starting point of Río Grande de Santiago, which some treat as a continuation of the Lerma River. In combination, the two are often called the Lerma Santiago River (). The Lerma River is notorious for its pollution, but the water quality has demonstrated considerable improvement in recent years due mostly to government environmental programs and through a vast program of upgrading local sanitation infrastructure. Course The Lerma River originates from the Lerma lagoons near Almoloya del Río, on a plateau more than above sea level, and southeast from the city of Toluca. The lagoons receive their water from springs rising from basaltic volcanics that flow down from Monte de Las Cruces. These are locate ...

Ameca River
The Ameca River () is a river of some in length in western Mexico. It originates in the Bosque de la Primavera in Jalisco, 23 km to the west of state capital Guadalajara; flows through the city of Ameca; and then forms the boundary between Jalisco and Nayarit on its way to the Pacific Ocean, where it drains into the Bahía de Banderas at Puerto Vallarta, Jalisco. Its main tributaries are the Ahuacatlán and Amatlán de Cañas. The Ameca has been dammed just north of the town of La Vega, Jalisco, forming a reservoir, the Lago La Vega which extends northward to the town of Teuchitlán. Fish Several species of fish are only found in the Ameca River basin: the butterfly splitfin, Tequila splitfin, finescale splitfin, banded allotoca, golden skiffia, Amatlan chub, Ameca chub and Ameca shiner. All these are highly threatened. The Tequila splitfin, finescale splitfin and golden skiffia are likely already extinct in the wild A species that is extinct in the ...

Ictalurus
''Ictalurus'' is a genus of North American freshwater catfishes. It includes the well-known channel catfish (''Ictalurus punctatus'') and blue catfish (''Ictalurus furcatus''). The catfish genome database (cBARBEL) is a database for the genetics of ''Ictalurus'' species. Distribution Members of this genus are primarily found in the Mississippi River basin & peninsular Florida, and range south to southern Mexico, where several range-restricted species are known. Some species, such as the channel and blue catfish, have been introduced to parts of North America west of the Rocky Mountains and east of the Appalachian Mountains, where they are otherwise not native. However, the fossil species ''Ictalurus countermani'', known from the Miocene of Maryland, suggests that this genus did naturally inhabit the Atlantic-draining rivers east of the Appalachians during the Neogene. Species Currently, 10 species in this genus are recognized: * '' Ictalurus australis'' ( Meek, 1904) (Pan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
