Tujuan dari penelitian ini adalah untuk menganalisis perubahan dalam perkembangan gonad kerang Anadara granosa di Lhokseumawe, bagian utara Selat Malaka dalam hubungannya dengan fluktuasi kualitas air harian. Untuk menentukan periode pemijahan populasi kerang, dilakukan analisis indeks kondisi (condition index/CI). Sampel kerang dikumpulkan dari Juli 2009 sampai Mei 2010 dan parameter kualitas air turut diukur secara berkala. Indeks kondisi tertinggi dari populasi kerang diamati pada Oktober 2009 (13.97±3.49), sedangkan indek kondisi terendah ditemukan pada Januari 2010 (6.76±1.13). Periode pemijahan untuk A. granosa diketahui terjadi terus-menerus sepanjang tahun, dengan puncak pemijahan terjadi pada bulan Oktober 2009 sehingga Januari 2010. Suhu air dan salinitas harian di lokasi penelitian berkisar antara 24-34 oC dan 27-33 ppt. Periode pemijahan populasi A. granosa diketahui bertepatan dengan terjadinya fluktuasi secara drastis pada suhu air dan salinitas harian. Analisis kualitatif menunjukkan bahwa suhu dan salinitas adalah modulator utama peristiwa reproduksi. Ketika suhu dan salinitas berfluktuasi, aktifitas pemijahan secara sporadis terdeteksi pada spesies ini. Penelitian ini juga menunjukkan bahwa periode pemijahan yang diikuti oleh proses rekrutmen dalam populasi kerang A. granosa Lhokseumawe sangat tergantung pada kondisi lingkungan kawasan tersebut..
