Penelitian ini bertujuan untuk mengetahui variasi lebar karapas, berat tubuh, pola pertumbuhan, rasio jenis kelamin dan persentase tingkat kematangan gonad, hubungan lebar karapas dan berat tubuh dan siklus reproduksi rajungan di Desa Keboromo. Penelitian ini menggunakan metode deskriptif. Hasil dari penelitian ini menunjukkan dari 977 ekor rajungan yang diamati, sebaran ukuran lebar karapas rajungan rajungan jantan dan betina yang tertangkap selama penelitian berkisar antara 50-169 mm dengan nilai total tertinggi berada pada interval 100-109 mm dengan jumlah 358 ekor. Hubungan lebar karapas dan berat rajungan menghasilkan pola pertumbuhan alometrik negatif dengan nilai b sebesar 1,47 pada rajungan jantan dan 1,44 pada rajungan betina.
