The yellow shiner (Notropis calientis) is a species of
Rio Grande de Santiago and Rio Pánuco in central Mexico. It forms a species complex within the genus Notropis with the Ameca shiner and the now-extinct Durango shiner.[1]
Description
The yellow Shiner is a small fish with a deep, broad body which is at its deepest just in front of the origin of the
pectoral fins. The body is covered with large scales. These fish grow to a maximum length of 5 centimetres (2.0 in) and the females are larger than the males.[2]
Distribution and habitat
The yellow shiner is endemic to Mexico where it is found on the western Mexican Plateau where it is a widespread species being found on the drainage systems of the Rio Lerma, Rio Grande de Santiago, Rio Pánuco, and Lake Cuitzeo. In this region they occur in springs, spring fed lakes and small mountain streams.[2]
Biology
The behaviour of yellow shiners is almost unknown and more research is required.[2]
Conservation
The yellow shiner has not been evaluated by the
The IUCN Red List of Threatened Species[3] but it should be considered as near threatened as there has been a considerable degradation in habitat quality in the 20th Century and they are preyed upon by a number of species of introduced fish including guppies, tilapia, sunfish and species of black bass.[2] The Durango shiner, a close relative to the yellow shiner with a highly restricted range,[1] is considered to be extinct.[4]
