Pengambilan data dilakukan pada bulan November-Desember 2021 pada 3 stasiun.

Indeks keanekaragaman Stasiun 1 dan 3 dikategorikan keanekaragaman sedang, keanekaragaman di Stasiun 2 kategori keanekaragaman rendah. Indeks keseragaman pada ketiga stasiun dikategorikan rendah. Stasiun 2 terdapat dominasi sedangkan Stasiun 1 dan 3 tidak terdapat dominasi.

The data taken in the form of samples and water parameters (temperature, salinity, pH, substrate). Samples were taken using a 10m x 10m transect with 5 1m x 1m sub plots placed diagonally. The results showed that 11 species from 5 families were found, namely the family Potamididae 5 species, Ellobiidae 2 species, Neritidae 2 species, Helicarionidae 1 species and Littorinidae 1 species.
