      Abstract
      Evaluasi tingkat kematangan gonad ikan nila umumnya dilakukan melalui pengamatan makroskopis dan histologi yang bersifat invasif. Penelitian ini bertujuan untuk mengonfirmasi pemanfaatan radiografi digital kontras dan ultrasonografi (USG) sebagai metode non-invasif untuk mengevaluasi perkembangan ovarium ikan nila (Oreochromis niloticus) betina pada berbagai tingkat kematangan gonad. Penelitian dilakukan pada 20 ekor ikan nila betina dengan berbagai tingkat kematangan gonad. Pengamatan meliputi karakteristik citra radiografi digital kontras dan USG, morfologi makroskopis, histologi, indeks gonadosomatik (GSI), serta diameter oosit. Hasil penelitian menunjukkan bahwa radiografi digital kontras mampu memvisualisasikan bentuk, batas, dan distribusi struktur ovarium, sedangkan USG mampu menunjukkan perubahan ukuran dan pola ekogenisitas ovarium pada berbagai tingkat kematangan gonad. Hasil pengukuran diameter oosit menunjukkan pola perkembangan yang konsisten dengan histologi. Radiografi digital kontras dan USG dapat dimanfaatkan sebagai metode pendukung dalam mengevaluasi perkembangan ovarium ikan nila betina secara non-invasif serta berpotensi mendukung pemantauan reproduksi dan keberlanjutan penggunaan induk bernilai ekonomi dalam kegiatan pembenihan
       
      Evaluation of gonad maturity stages in tilapia is typically conducted through macroscopic and histological observations, which are invasive. This study aimed to validate the use of contrast-enhanced digital radiography and ultrasonography (USG) as non-invasive methods for evaluating ovarian development in female tilapia (Oreochromis niloticus) across various gonad maturity stages. The study involved 20 female tilapia specimens exhibiting different stages of gonad maturity. Observations encompassed the characteristics of contrast-enhanced digital radiographic and USG images, macroscopic morphology, histology, gonadosomatic index (GSI), and oocyte diameter. The results demonstrated that contrast-enhanced digital radiography could visualize the shape, boundaries, and distribution of ovarian structures, while USG revealed changes in ovarian size and echogenicity patterns across the different maturity stages. Oocyte diameter measurements showed a developmental pattern consistent with histological findings. Contrast-enhanced digital radiography and USG can serve as supportive, non-invasive methods for evaluating ovarian development in female tilapia and have the potential to facilitate reproductive monitoring and the sustainable use of economically valuable broodstock in hatchery operations.
