Abstract

ABSTRACT The Flinders Ranges Gudgeon (Mogurnda clivicola) in South Australia, is restricted to permanent spring-fed pools of two creeks in the Northern Flinders Ranges. Consequently, the fish is classified as critically endangered. Regular monitoring of selected water chemistry and fish population characteristics has been conducted since 2018 by a “Friends of Parks” group in an ongoing project contributing to the conservation management for this endangered species. Mogurnda clivicola were abundant and healthy in Weetootla and Nepouie springs, with six or fewer fish displaying any skin lesions on each of the four sampling occasions of May and August 2019 and June and August 2020. Hence the fish populations were not adversely affected by the exceptionally low rainfall years of 2018 and 2019. Fish of less than 2 cm total length were present at each sampling time point, indicating that breeding can occur on an opportunistic basis rather than during a breeding season. Following a substantial flood during February 2020, a substantial breeding event resulted in large numbers of small fish and at Nepouie Spring. For pools that contained fish, the water quality parameters measured and their ranges were: conductivity 1141–13 800 µS/cm; dissolved oxygen concentration 1.9–12.0 mg/L; temperature 11.4–29°C; pH 7.1–8.8; [Ca++] 36–213 mg/L; [NO3-] 0.2–17.7 mg/L.

弗林德斯山脉的水质参数和种群特征
南澳大利亚的弗林德斯山脉古吉翁(Mogurnda clivicola)是位于弗林德斯山脉北部的两条小溪的永久泉水池。因此,这种鱼被列为极度濒危物种。自2018年以来,“公园之友”小组对选定的水化学和鱼类种群特征进行了定期监测,这是一个正在进行的项目,有助于对这种濒危物种的保护管理。在Weetootla和Nepouie泉中,Mogurnda clivicola数量丰富且健康,在2019年5月和8月以及2020年6月和8月的四次采样中,每一次都有6条或更少的鱼出现任何皮肤病变。因此,鱼类种群没有受到2018年和2019年异常低降雨量的不利影响。在每个采样时间点都有总长度小于2厘米的鱼,这表明繁殖可能是机会性的,而不是在繁殖季节。在2020年2月的一场大洪水之后,一场大规模的繁殖活动导致了大量的小鱼和Nepouie Spring。对于有鱼的水池,测量的水质参数及其范围为:电导率1141 ~ 13800µS/cm;溶解氧浓度1.9 ~ 12.0 mg/L;温度11.4 -29°C;pH值7.1 - -8.8;[Ca++] 36-213 mg/L;[NO3-] 0.2 ~ 17.7 mg/L。

期刊介绍: Published since 1880, the Transactions of the Royal Society of South Australia is a multidisciplinary journal that aims to publish high quality, peer-reviewed papers of particular relevance to Australasia. There is a particular focus on natural history topics such as: botany, zoology, geology, geomorphology, palaeontology, meteorology, geophysics, biophysics, soil science and environmental science, and environmental health. However, the journal is not restricted to these fields, with papers concerning epidemiology, ethnology, anthropology, linguistics, and the history of science and exploration also welcomed. Submissions are welcome from all authors, and membership of the Royal Society of South Australia is not required. The following types of manuscripts are welcome: Reviews, Original Research Papers, History of Science and Exploration, Brief Communications, Obituaries.
