Tujuan penelitian ini adalah untuk mengetahui variasi ukuran lebar karapas dan berat tubuh, rasio jenis kelamin, dan tingkat kematangan gonad dari rajungan ( Portunus pelagicus ) di Perairan Desa Danasari Pemalang dan sekitarnya. Penelitian ini mempergunakan metoda deskriptif kuantitatif untuk mengetahui tingkat kematangan gonad rajungan dan metode purposive sampling untuk menentukan titik pengambilan sampel.

Sampel rajungan yang telah dikumpulkan berjumlah 1283 ekor (759 ekor rajungan jantan dan 524 ekor rajungan betina). Hasil dari penelitian ini menunjukkan rajungan yang paling banyak ditemukan memiliki ukuran lebar karapas yang berkisar antara 107-115 milimeter dan berat tubuh 73-93 gram dengan persamaan hubungan lebar karapas dan berat tubuh sebesar 0,0003L 2,6983 untuk rajungan betina dan 0,0002L 2,7431 untuk rajungan jantan. Rajungan yang ditemukan lebih banyak berkelamin jantan dibandingkan betina. Rajungan betina yang ditemukan sudah dalam usia dewasa dengan TKG kategori 2 ( Matured ). Hasil tersebut menunjukkan kondisi rajungan ( Portunus pelagicus ) di Perairan Desa Danasari Pemalang memiliki komposisi berdasarkan ukuran, dan tingkat kematangan gonad yang cukup ideal, namun untuk rasio jenis kelamin didapatkan tidak ideal karena menunjukkan hasil perbandingan rajungan jantan dengan rajungan betina tidak seimbang.

These results indicate that the condition of the blue swimming crab (Portunus pelagicus) in the waters of Danasari Pemalang Village has a composition based on size, and the level of gonadal maturity is quite ideal, but the sex ratio is not ideal because it shows the results of the comparison between male and female crabs are not balanced. }, issn = {2407-7690}, pages = {73--82} doi = {10.14710/jmr.v13i1.37986}, url = {https://ejournal3.undip.ac.id/index.php/jmr/article/view/37986} }
