“…The result showed a total of 896 gastropod snails belonging to 6 species. 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.…”

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.

Fresh water snails in Jakara dam were investigated for different types of cercariae. Snails were collected from different parts of the dam in Minjibir, Ugoggo and Gezawa local government area between October 2016 and January 2017 by hand picking only and placed separately in compartmented petridishes for cercarial shedding. Result showed that twenty one snail species from two families comprising Lymnaeidae and Planorbidae were encountered. Bulinus species collected are B. globosus morelet, B. reticulatus, B. truncatus rohlfsi, B truncatus truncatus Egypt, B jousseammei, B. succinoides and B. camerunensis. Fourteen species of Lymnea were encountered from different parts of the dam. Lymnea species encountered are Peplimnea affinus ((Küster,1862), Lymnea (Pseudosuccina) columella, L. natalensis, Lymnaea ollula, L. tormentosa, L.auricularis rubiginosa with one of them shedding more than a hundred cercariae. Most of these lymnea species cannot be identified or named. Twelve different types of cercaria were discovered but only nine of them were presumably identified as Virgulate, Ubiquita, Gymnocephalus, Amphistome, Echinostome, Armatae cercaria, Parapleurolophocercous cercariae, Ornatae and Fucocercus cercaria (videos of swimming available), three of them cannot be identified. Lymnea species from Bangare showed the most infection with one of them shedding more than a hundred cercariae. There was no schistosome cercariae. This is the first time more than three types of cercariae were observed in Jakara dam. Data analysis was done descriptively. The presence of these new types of cercariae may not be unconnected with the presence of different species of Lymnea encountered in the water body and may mean a new trend in trematode infection.
