Abstract

Penelitian dilakukan di Pulau Tobea dengan tujuan untuk menganalisis nisbah kelamin dan ukuran pertama matang gonad kerang lumpur. Data dianalisis untuk mengetahui nisbah kelamin dan ukuran pertama matang gonad kerang lumpur Pulau Tobea dengan menggunakan analisis chisquare (χ2) dan Metode Spearmen-Karber (Udupa, 1986). Hasil analisis nisbah kelamin dengan menggunakan chi-square berdasarkan stasiun pengambilan sampel, waktu pengambilan dan tingkat kematangan gonad (TKG) menunjukkan nisbah kelamin jantan kerang lumpur lebih sedikit dibandingkan dengan jenis kelamin betina. Hal ini ditunjukkan dengan nilai chi-square hitung > chi-square tabel baik berdasarkan waktu pengambilan sampel (6,3700>4,3027), berdasarkan stasiun pengamatan (6,6673>4,3027), berdasarkan tingkat kematangan gonad (TKG) (6,6673>4,3027). Ukuran pertama matang gonad kerang lumpur, jenis kelamin jantan mencapai ukuran matang gonad rata-rata panjang cangkang sebesar 39,62 mm, pada kisaran panjang cangkang sebesar 39,20-40,04 mm. Untuk jenis kelamin betina mencapai ukuran pertama matang gonad rata-rata panjang cangkang sebesar 39,58 mm, pada kisaran panjang cangkang sebesar 39,21-39,96 mm. Kerang lumpur di Pulau Tobea, ukuran pertama matang gonad sebenarnya untuk jenis kelamin jantan mencapai ukuran panjang cangkang sebesar 39,7 mm dan jenis kelamin betina mencapai ukuran panjang cangkang sebesar 38,0 mm.
