“…Gambusia detected in this study was Gambusia affinis. Gambusia affinis originates from the southeastern coastal region of the United States and has been widely introduced to the world for mosquito control (Chabet et al 2022). According to Wahyudewantoro and Rachmatika (2016), Gambusia affinis is relatively small, approximately 4 cm long, with a slightly curved back.…”

Abstract. Rahmi KA, Adharini RI, Sari DWK, Satriyo TB. 2023. Detection of the presence and distribution of invasive fish in the Progo River, Yogyakarta, Indonesia using the environmental DNA method. Biodiversitas 24: 276-281. Invasive species are alien species that enter the ecosystem and can adapt to the ecosystem quickly. So, the presence of invasive fish can threaten endemic diversity in these ecosystems. This study aims to detect the presence and distribution of invasive fish in the Progo River, Yogyakarta, Indonesia, through the environmental DNA (eDNA) method. Water samples were taken at three observation points in the upstream area of the river (site 1), the middle of the river (site 2), and downstream of the river (site 3). The water samples were filtered using 0.45 µm MF-Milipore installed on the filtration pump and extracted using the ZymoBIOMICS DNA Miniprep Kit. Sequencing used nanopore sequencing. The primers used were FishF2 and FishR2. The sequencing results were analyzed using the mBRAVE software, which was then classified as an invasive species based on government regulations and journals. The results showed that 188 OTUs were detected in the upstream area (site 1), 227 OTUs in the middle area (site 2) and 154 OTUs downstream. Lagocephalus and Sciaenops were found in the upstream area (site 1). In the middle area of the river (site 2), Gambusia and Lepomis were found, while in the lower reaches of the river (site 3), Gambusia and Sciaenops were found. With the detection of these invasive species, appropriate management and conservation efforts must be carried out immediately to protect endemic species in the Progo River.

“…A survey conducted at Algerian freshwater sites between 2007 and 2010 collected G. a nis at 7.7% abundance in rivers and lakes (23 out of 39 sites) (Chaibi, et al, 2012), although locations are not speci ed. In 2016, established G. a nis populations were studied in Oubeira lake (Chabet Dis, et al, 2022). Established G. a nis have been con rmed by sampling of multiple specimens at the Gazelle fountain dam in Biskra in 2007, Timimoune's foggara between 2010-11, wadi Sebaine in Tiaret between 2017-2018, and at a small dam in Bechar in 2018 (Sellaoui and Bounaceur, 2020).…”

Background. This review compiles and synthesises the existing information concerning non-native poecillid introductions to Africa. The recent upsurge in research on invasive poeciliids has revealed their widespread occurrence in Africa. Results. Within the 87 relevant articles, 74% reported on the presence Gambusia spp., 33% on P. reticulata, 19% on X. hellerii, 11% on X. maculatus, and 5% on other ornamental poeciliids. Overall, poeciliids have been introduced to 25 different countries in Africa, with Gambusia spp. being introduced to 16 countries and P. reticulata to 19 countries. Our results are representative of the current state of research on invasive poecilids in Africa. In particular there was a concentration of studies in South Africa, with limited research elsewhere. Current distribution data is relatively patchy, although widespread surveys of multiple river systems in Morocco and South Africa, confirmed widespread and abundant established poeciliid populations. The ecological impacts of invasive poeciliids in Africa remain understudied but evidence indicates deleterious effects on native fish, invertebrates, and amphibians, many of which are critically endangered or endemic species. Conclusion. An increased effort to monitor species composition in vulnerable waterbodies, especially in the many African countries where invasive poeciliids are reported should be completed and to reveal further established populations. Future research should prioritise quantifying the ecological impacts of invasive poeciliids in the field and identifying both vulnerable and resistant native ecosystems to guide future management decisions.

This research aims to analyze condition of the aquatic environment from the physical and chemical aspects of the waters and analyze the health of fish in supporting the sustainability of fish resources in the upper part of the Asahan River. Sampling was carried out by purposive sampling method at nine stations obtained in situ and secondary data. The results showed that in general the quality of the waters upstream of the Asahan River was below the second class of river water quality standard. However, it is necessary to monitor regularly the parameters of ammonia and oil content in the waters of the Asahan River so as not to exceed the second class of river water quality standard, because this had implications for the development of the parasite population of Alitropus sp. In addition, the emergence of a population of fish lice (Alitropus sp.) has also caused many fish that used to inhabit the upper reaches of the Asahan River, there is only one species, namely Asa Fish (Osteochillus vittatus) and freshwater lobster (Cherax quadricarinatus). Several physical and chemical parameters of the waters have a positive effect on the development of the Alitropus typus parasite, including temperature, brightness, ammonia and pH.
