Pengambilan sampel sebanyak 30 individu dilakukan pada bulan Mei-Oktober tahun 2012 dengan interval waktu 2 minggu sekali. Pengamatan dilakukan secara langsung meliputi morfometri panjang tubuh dan berat tubuh Lorjuk serta diameter oositnya. Tingkat Kematangan Gonad dilakukan dengan pengamatan histologi gonad dan mengelompokkan TKG berdasarkan ilustrasi photomicrograph skala gametogenik pada Ensis arcuatus. Hubungan antara Tingkat Kematangan Gonad dengan diameter oosit Lorjuk mengikuti persamaan TKG=0.522 + 0.528 diameter oosit dengan korelasi sebesar 79.2.
