200L Biotope Aquascape Profundulus oaxacae habitat

Víctor Manuel Ortiz Cruz · Mexico

Biotope description: This 缸体 has been designed based on the recently discovered population of the killifish Profundulus oaxacae, a species about which very little is known and which is on the border of extinction due to the destruction and contamination of the watershed in which it was abundant until several decades ago (the river Atoyac in the state of Oaxaca, Mexico) The habitat in which the 2nd confirmed existing population of this species was found is a micro watershed. More specifically it is the source of a stream which finds its way through a ravine surrounded by oak trees that constantly shed their leaves in the stream, and forming different small pools. Note that this population is isolated from the last of the species considered. The stream finds its way through whitish rocks and the border is littered with small wooden trunks and roots, both covered in mosses with a large quantity of ferns, followed in abundance by Eleocharis parvula (there are other species of the same genus but this is the species that is in direct contact with the water). In the pools a native water lily (Heteranthera reniformis) can be found, as well as Ludwigia peploides, Bacopa monnieri, the macro algae Chara sp. At the bottom of the stream a small rosette type plant is found which has not been identified up to now. The bottom of the stream is mostly sandy covered with organic matter due to the decomposition of the oak leaves. Profundulus oaxacae cohabiting in the last pools of the creek where he found with Poecilia sphenops, although the prevalence is higher killifish, being in the lowest part of the stream populations Profundulus disappear and is greater P . sphenops with other 鱼类 of the family Poecilidae. It is worthwhile mentioning that the area of the recently discovered population of the Oaxacan killifish, is seriously threatened due to the advancing limits of the urban population. For this reason, the local municipal authority, together with a collective of environmentalists and the expertise of an aquatic biologist, that discovered the population, tries to protect this area and the Profundulus oaxacae. Through the participation in this contest we try to generate interest in and awareness about these efforts in order to obtain support of those interested.
