Description of the Area Surrounding the Biotope: Laguna de Sayula (“Sayula Lake”) is a lake located in the southern area of Jalisco, about 60 km from Guadalajara. It is located in the municipalities of Sayula, Zacoalco de Torres, Amacueca, Teocuitatlán de Corona, Atoyac and Techaluta de Montenegro.
生物群落周边区域描述：萨尤拉湖（Laguna de Sayula）位于哈利斯科州南部，距瓜达拉哈拉约 60 公里。该湖横跨萨尤拉、萨科阿尔科德托雷斯、阿马库埃卡、特奥库伊塔特兰德科罗纳、阿托亚克以及特查卢塔德蒙特内格罗等市镇。
The lake level has gradually been lowering since 1993 but it still supports a large variety of wildlife
自 1993 年以来，湖泊水位逐渐下降，但仍支撑着丰富的野生动植物多样性。
Laguna de Sayula is a wetland with Ramsar (an important place for bird conservation), the wetlands are ecosystems where water is the main factor controlling the environment, vegetable life and animals associated with it. The lakes of the closed Sayula-Atotonilco basin form part of the endorheic lakes of the neo-volcanic axis. But Laguna de Sayula is especially important because of its relation to the migratory habitats of the North American birds.
萨尤拉湖是一处拉姆萨尔湿地（鸟类保护的重要场所）。湿地是以水为主要环境控制因子，并孕育相应植被与动物群落的生态系统。封闭的萨尤拉 – 阿托托尼尔科流域中的湖泊属于新火山轴的内流湖群。而萨尤拉湖尤为重要，因其与北美候鸟的迁徙栖息地密切相关。
The described biotpe in this location refers on a Species of fish named Skiffia Francesae.
本地点所描述的生物群落涉及一种名为 Skiffia francesae 的鱼类。

* The following presentation,refers on the period tha Skiffia Francesae existed in their natural habitat. Skiffia francesae is not existing in Laguna dE SAyula anymore (see Threats for the ecology ) *
* 以下介绍涉及 Skiffia francesae 在其自然栖息地存在的时期。Skiffia francesae 已不再存在于 Laguna de Sayula（参见生态威胁部分）。*

The Golden Skiffia is endemic to the Mexican federal state of Jalisco. It was historically only known from the Río Teuchitlán in the Río Ameca headwaters and from the Río Ameca itself about 12km E of the town of Ameca. Individuals collected in 2007 from the El Molino pond in the endorheic Laguna de Sayula basin also belong to this species, and those from the Presa La Ciénaga (Presa Buenavista), upper Río Ameca drainage, should be Golden Skiffia as well due to the drainage (determined as Skiffia multipunctata in 1963, so before Skiffia francesae was described)
金斯基菲亚鱼（Golden Skiffia）为墨西哥哈利斯科州特有物种。历史上，该物种仅见于阿梅卡河（Río Ameca）上游的特乌奇特兰河（Río Teuchitlán），以及阿梅卡镇以东约 12 公里处的阿梅卡河干流。2007 年从封闭性流域萨尤拉湖（Laguna de Sayula）盆地内的埃尔莫利诺池塘（El Molino pond）采集的个体也属于该物种；此外，来自阿梅卡河上游流域的普雷萨拉西埃纳加水库（Presa La Ciénaga，又称普雷萨布埃纳维斯塔水库 Presa Buenavista）的种群，基于其流域归属，亦应归为金斯基菲亚鱼（该种群于 1963 年被鉴定为多斑斯基菲亚鱼 Skiffia multipunctata，当时金斯基菲亚鱼尚未被描述）。
However, this species disappeared from all of these habitats and only persists in aquariums. Two subpopulations are recognized: The Upper Río Ameca subpopulation (type subpopulation) and the Laguna de Sayula subpopulation. Both are regarded Extinct in the Wild
然而，该物种已从上述所有栖息地消失，目前仅存于水族箱中。现已确认两个亚种群：阿梅卡河上游亚种群（模式亚种群）和萨尤拉湖亚种群。两者均被评估为“野外灭绝”。

Description of the Underwater Landscape of the Biotope: The former habitat in was a quiet, thermal and clear to murky water with only a slight current. Substrate was deep mud with a few rocks, silt and sand. Few species of aquatic plants were only present, such as Ceratophyllum ,Lemna sp, Potamogeton etc
生物群落水下景观描述：该地曾经的栖息地是一片静谧的水域，水温偏暖，水质从清澈到浑浊不等，水流微弱。底质为深厚的淤泥，夹杂少量岩石、粉砂和沙子。水生植物种类稀少，仅见有金鱼藻（Ceratophyllum）、浮萍属（Lemna sp.）、眼子菜属（Potamogeton）等。

Description of the Habitat Parameters: Temp 18-26c
栖息地参数描述：水温 18–26°C

Threats to the Ecology of the Biotope: As already mention Skiffia francesae are extinct from their natural habitat
该生物栖息地生态面临的威胁：正如前文所述，Skiffia francesae 已在其自然栖息地中灭绝。
[…] Two subpopulations are recognized: The Upper Río Ameca subpopulation (type subpopulation) and the Laguna de Sayula subpopulation. Both are regarded Extinct in the Wild.
[…] 已确认存在两个亚种群：上阿梅卡河（Río Ameca）亚种群（模式亚种群）和萨尤拉湖（Laguna de Sayula）亚种群。两者均被认定为“野外灭绝”。
[…]Extinct in the Wild/no records since 2008: „This species had long been thought to be endemic to the Teuchitlán Springs in the upper Ameca River basin and was already believed extinct in the wild when it was first formally described as a species in 1978 (Kingston, 1978; Miller et al., 1989). Fortunately, captive populations exist in North America and Europe, although many of these are inbred (Domínguez-Domínguez et al., 2005). In 2007, Omar Domínguez-Domínguez discovered a new population of Skiffia that suggested that S. francesae might still persist in wild. These fish were found at the El Molino spring pond near the town of Cuyucapán in the endorheic Lake Sayula basin, which is located ca. 80 km south of the Teuchitlán Springs.
[…] 野外灭绝/自 2008 年以来无记录：“长期以来，人们认为该物种是阿梅卡河上游特乌奇特兰泉（Teuchitlán Springs）的特有种，并且在 1978 年首次被正式描述为独立物种时，就被认为已在野外灭绝（Kingston, 1978; Miller et al., 1989）。幸运的是，北美和欧洲尚存人工饲养种群，尽管其中许多存在近亲繁殖问题（Domínguez-Domínguez et al., 2005）。2007 年，Omar Domínguez-Domínguez 发现了一个新的 Skiffia 种群，表明 S. francesae 可能仍在野外存续。这些鱼类发现于萨尤拉内流湖盆地库尤卡潘镇附近的埃尔莫利诺（El Molino）泉池，该地点位于特乌奇特兰泉以南约 80 公里处。
Unfortunately, the El Molino population was eliminated when the pond dried completed during a drought in 2010. Thus, both types are extinct in the wild. Moderate numbers of captive populations of Skifia exist in Mexico, the United States, and Europe
不幸的是，2010 年干旱期间池塘完全干涸，导致埃尔莫利诺（El Molino）种群灭绝。因此，这两个类型在野外均已灭绝。目前，墨西哥、美国和欧洲仍存有数量适中的斯氏鱼（Skifia）人工饲养种群。
