Penelitian ini bertujuan untuk mengamati kekayaan jenis, keanekaragaman dan kelimpahan gastropoda mangrove di pesisir Desa Kramat, Kabupaten Boalemo, Provinsi Gorontalo. Penelitian dilakukan dengan cara mensurvei populasi gastropoda menggunakan kuadran berukuran 5x5 m yang dibuat pada tiga transek garis (LT) yang berbeda berdasarkan lebar sabuk mangrove. Hasil penelitian menunjukkan bahwa jumlah spesies gastropoda di ekosistem mangrove adalah 14 yang mewakili anggota 8 famili.

Nilai indeks keanekaragaman Shannon-Wiener untuk semua spesies berkisar antara 1,517 hingga 2,177. Nilai indeks dispersi Morisita berkisar antara 0,97–14,00 untuk tingkat spesies dan 0,97–4,67 untuk tingkat famili.

This research aimed to observe species richness, diversity, and the abundance of mangrove gastropods on the coast of Kramat Village, Boalemo Regency, Gorontalo Province. The study was conducted by surveying the gastropod population using a 5x5 m quadrant established on three different line transects (LT) based on the width of the mangrove belt. The study's results showed that the number of gastropod species in the mangrove ecosystem was 14, representing members of 8 families.
