“…Similarly, Duwa [22] recorded 14 species of freshwater snails in three parts of Jakara Dam, Kano State, Nigeria. Priawandiputra et al [23] noted that precipitation during the rainy season influenced the population abundance and composition of 14 freshwater gastropod species recorded in the Gede system. Olorunniyi and Olofintoye [24] reported the coexistence of freshwater snail species namely P. moerchi, and Lanites libycus, and B. globosus, in six streams and a total of 4 snail species namely P. moerchi, Lanites libycus, B. globosus, and Bellamyia unicolar from their study of the occurrence and distribution of freshwater snails in three communities of Ekiti State, Nigeria.…”

Rapid diversification is a way of responding to environmental change for freshwater organisms. This work examined the physicochemical changes and abundance of freshwater snails in Anambra River (Nigeria) during the rainy season. Field studies were conducted fortnightly from June to August 2019 at three stations of the river namely: Otuocha (station I), Otunsugbe (station II), and Ukwubili (station III) about 8.35 kilometers apart from each other. A scoop net of 2 cm mesh size and handpicking was used to sample freshwater snails randomly and water samples were taken to the laboratory for physicochemical analysis. A total of 896 freshwater snails belonging to 6 species (Afropomus balanoidea, Pomacea maculata, Lymnea stagnalis, Lanistes ovum, Pila wernei, and Saulea vitrea) were collected. Pomacea maculata was the most dominant species with a relative abundance of 45.87 %, while Saulea vitrea was the least dominant species with a relative abundance of 2.34 %. There was a significant negative correlation between dissolved oxygen and Pomacea maculate (r = –0.877, p = 0.002) and a positive correlation between dissolved oxygen and Stagnalis lymnea (r = 0.840, p = 0.005). The diversity of species was highest at Otuocha (1.171) followed by Ukwubili (1.133) and Otunsugbe (0.856) with average mean temperatures of (23.1 ±0.1) °C, (27.30 ±0.00) °C, and (26.80 ±0.03) °C respectively. The distribution of freshwater snails was influenced by the physicochemical variability of Anambra River during the rainy season. Therefore, further studies for a longer time and different seasons to examine the impact of physicochemical changes on the snail distribution are encouraged.

“…Jenis-jenis gastropoda yang asalnya dari Pulau Jawa dapat menyebar melalui produk pertanian kemudian berkembang di wilayah baru. Jenis yang ditemukan di dalam penelitian ini lebih sedikit dibandingkan dengan temuan sebelumnya pada situ di daerah Bogor yang berkisar dari 12-14 jenis gastropoda (Marwoto dan Isnaningsih (2014); Priawandiputra et al (2017); Mujiono et al (2019). Jenis Filopaludina javanica sebelumnya teramati di Sungai Ciliwung (Marwoto dan Isnaningsih 2014;Mujiono et al 2019) dan di beberapa situ di Jawa Barat (Priawandiputra 2020).…”

Despite being part of food web and bioindicator in freshwater ecosystems, gastropods are globally jeopardized. Therefore, the occurence of freshwater gastropods need to be assessed. This research aimed to examine diversity and distribution of freshwater gastropods along the Ciapus River in Bogor, West Java, Indonesia. The research was conducted from February to May 2020. Sampling was carried out within limited 15 minutes time period using five 1 × 1 m plots established at each of four survey stations. Gastropods were collected from the bottom of river, rock surface and riverbanks within 15-100 cm of water depth. Environmental parameters were recorded. Data was analyzed using biodiversity index parameters and diversity t-test. The survey collected a total 587 individuals from 7 species of freshwater gastropods. The abundance, species richness and diversity of gastropods in the Ciapus river were different between upstream and downstream, location with high altitude tend to have low number of species. Glyptophysa stagnalis became the only species recorded from upstream area. Meanwhile, there were 4 species, which were collected in other three stations and 2 species that recorded from two stations. In three stations, Tarebia granifera was the most dominant species.

“…Except for N. porcata, the other 2 species appeared to be higher during dry season. Accordingly, the abundance of gastropods could be attributed to the high rates of biological activities during dry season and high precipitation rate during the wet season (Ndifon and Ukoli, 1989;Priawandiputra et al, 2017). to the ponds with a coal shale bottom (Strzelec et al, 2014).…”

Bigaan river is around 19 kilometers (km) from Gango, Libona, Bukidnon down to Cagayan de Oro City (Philippines) and ends up in the Macajalar Bay. This study investigated species composition and abundance of gastropods along the river's stretch during wet and dry seasons. Sampling areas differ in elevation. Three species were found to be relatively abundant: N. porcata>M. tuberculata>P. canaliculata. Two sepcies -P. canaliculata and M. tuberculata were considered to be site-specific while N. porcata was present in all sampling areas.Abundance differs between seasons. Except for N. porcata, the 2 other species have small, medium and large sizes. With various kinds of pollutants discharged to Bigaan river, abundance of species faces huge threat. Therefore, measures in implementing programs for environmental protection need urgent and serious attention.
