Abstract


Otolit sagita ikan Selar crumenophthalmus (Bloch, 1793) telah ditelaah untuk menentukan perbedaan stok ikan lewat morfometri dan indeks bentuknya. Sampel otolit bersumber dari sebanyak 280 individu ikan tangkapan di perairan pantai Kema dan di perairan pantai Manado. Otolit sagita pada sisi kiri dan kanan kepala ikan diekstrak dan dibersihkan, kemudian difoto di bawah mikroskop dalam keadaan bersih. Selanjutnya lewat piranti ImageJ ditentukan besaran deskriptor otolit dan indeks bentuknya. Panjang total selar bentong ini (110-235 mm) ditemukan signifikan menentukan deskriptor otolit. Sementara variasi deskriptor otolit, diantaranya luas otolit (8,11-9,81 mm2) tidak menunjukkan perbedaan baik antara otolit kiri dan otolit kanan pada ikan jantan dan betina, tapi berbeda antara ikan selar bentong dari kedua perairan pantai tersebut. Perbedaan signifikan indeks bentuk otolit, juga ditunjukkan dari sampel ikan bentong dari kedua perairan pantai di Sulawesei Utara ini, pada indeks kebundaran otolit kanan dari ikan jantan, dan indeks keliling per luas otolit kanan dari ikan betina
