Penelitian ini berjudul “Keanekaragaman Ikan-Ikan Spesies Asli di Hilir Sungai Serayu, Kecamatan Kebasen, Kabupaten Banyumas, Jawa Tengah”. Keanekaragaman mencakup berbagai macam kehidupan baik manusia, tumbuhan, hewan, serta ekosistem yang membentuk lingkungan hidup. Tujuan penelitian untuk memahami keanekaragaman ikan-ikan spesies asli di hilir Sungai Serayu. Penelitian dilaksanakan pada bulan November dan Desember 2025 di hilir Sungai Serayu dan Laboratorium FPIK Unsoed. Metode penelitian menggunakan survey dan purposive sampling. Analisis data menggunakan kelimpahan relatif, indeks keanekaragaman Shannon-Wiener dan indeks dominansi. Hasil penelitian menunjukkan kelimpahan dari 9 spesies ikan asli pada bulan November dan Desember termasuk kategori melimpah dengan kelimpahan relatif 11-20%. Indeks keanekaragaman ikan spesies asli termasuk dalam kategori sedang dengan H’ (2,192) pada bulan November dan H’ (2,189) pada bulan Desember. Indeks dominansi ikan spesies asli termasuk ke dalam kategori rendah pada bulan November (0,112) dan Desember (0,113). Kesimpulan penelitian menunjukkan bahwa keanekaragaman spesies ikan asli cukup beragam, dengan kelimpahan ikan asli yang melimpah dan tidak terdapat spesies yang mendominasi.

This research is entitled "Diversity of Native Fish Species in the Lower Serayu River, Kebasen District, Banyumas Regency, Central Java". Diversity includes various kinds of life, including humans, plants, animals, and ecosystems that form the living environment. The aim of the research is to understand the diversity of native fish species in the lower reaches of the Serayu River. The research was conducted in November and December 2025 in the downstream of the Serayu River and the FPIK Unsoed Laboratory. The research method uses survey and purposive sampling. Data analysis utilized relative abundance, the Shannon-Wiener diversity index, and the dominance index. The results of the research showed that the abundance of 9 native fish species in November and December was included in the abundant category with a relative abundance of 11-20%. The diversity index of native fish species is included in the moderate category with H’ (2.192) in November and H’ (2.189) in December. The dominance index of native fish species was included in the low category in November (0.112) and December (0.113). The research conclusion shows that the diversity of native fish species is quite diverse, with an abundance of native fish and no dominant species.
