Abstract

fetched live from OpenAlex

Ikan kerapu Epinephelus areolatus adalah salah satu spesies ikan laut dalam genus Epinephelus yang penting secara ekologi, ekonomi, biologi, dan pangan. Genus ini tergolong tinggi tingkat keanekaragamannya. Meskipun demikian, informasi keragaman genetik spesies E. areolatus di bagian selatan bentang laut kepala burung Papua (Bird’s Head Seascape, BHS) masih terbatas. Tujuan penelitian ini adalah menentukan keragaman genetik ikan kerapu E. areolatus baik secara individu, populasi, dan antar populasi di selatan BHS. Untuk mencapai tujuan ini, peneliti telah mengumpulkan sampel ikan dari Fakfak dan Kaimana pada Agustus 2024. Analisis laboratorium dilakukan pada September 2025 menggunakan penanda genetik Cytochrome c oxidase sub unit 1 (COI) DNA mitokondria. Isolasi genom, amplifikasi gen COI, elektroforesis dan sekuensing fragmen gen COI adalah tahapan dalam analisis laboratorium ini. Hasil sekuensing pada 13 individu memperoleh panjang fragmen 665 panjang basa (pb). Hasil blast dan boldsystem terhadap ke-13 sekuens individu memastikan 12 sampel diantaranya adalah E. areolatus. Total teridientifikasi 35 sisi nukleotida yang berbeda antar individu spesies E. areolatus. Total 6 haplotipe yang teridentifikasi pada penelitian ini dengan keragaman haplotipe (Hd) populasi E. areolatus di Kaimana 0,85714 dan keragaman nukleotida (Pi) 0,0193, sedangkan keragaman haplotipe di perairan Fakfak sebesar 0.8333 dan keragaman nukleotida 0,0272. Jarak genetik rata-rata antar individu adalah 0.000 – 0.053. Ikan kerapu Fakfak dan Kaimana memiliki hubungan yang sangat dekat yang ditunjukkan oleh pohon filogenetik dan jaringan haplotipe. Populasi ikan BHS ini juga mengalami pencampuran genetik dengan spesies yang sama asal perairan Pasifik seperti China, Philipina, Canada, dan lainnya.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
