Daftar Isi:
- Aquatic organisms or nekton have an important role in supporting the stability of the aquatic environment and human life. This study aims to determine the nekton type community, ecological index, and their conservation status in the Unda River area and around Jumpai Beach, Klungkung Regency, Bali. The study was conducted in July - August 2020. The study was conducted in 2 communities, namely Macrozoobenthos and Nekton. Macrozoobenthos samples were collected using the quadratic method in the Jumpai Beach area and the direct observation method along the Unda River. Nekton communities are collected through primary data using "survey methods" and secondary data through interviews with fishermen and local communities. The ecological index data were analyzed using the Shannon-Weiner diversity index (H'), dominance index (C), and uniformity index (E), while the data on Nekton type and conservation status were analyzed descriptively. The nekton species community in the waters of the Unda River and Jumpai Beach areas was obtained as many as 26 species in 21 families which were dominated by Kepala Timah (Aplocheilus panchax) and sepat rawa (Trichogaster trichopterus), while Nautica sp for the Macrozoobenthos community. The ecological index of the aquatic community is the Shannon-Weiner Diversity Index (H') value of 2.98 (moderate), the wealth index (R) of 3.95 (moderate), and the evenness index (E) of 1.21. (High). The highest percentage ratio of nekton communities was obtained by the Macrozoobenthos community, namely 53%, while the nekton species was 46%. Conservation status shows that 13 species are included in the LC (Least Concern) category, 12 species are included in the NE (Not Evaluated) category, and 1 species are included in the VU (Vulnerable) category.
- Organisme akuatik atau nekton memiliki peranan yang penting dalam menunjang stabilitas lingkingan perairan dan kehidupan manusia. Penelitian ini bertujuan untuk mengetahui komunitas jenis nekton, indeks ekologi, dan status konservasinya di kawasan Sungai Unda dan sekitar Pantai Jumpai, Kabupaten Klungkung, Bali. Penelitian dilakukan pada Bulan Juli – Agustus 2020. Penelitian dilakukan pada 2 komunitas yaitu Makrozoobentos dan Nekton. Sampel makrozoobenthos dikumpulkan dengan metode kuadrat pada kawasan Pantai Jumpai dan Metode pengamatan langsung di sepanjang Sungai Unda. Komunitas nekton dikumpulkan melalui data primer yaitu menggunakan metode “survey methods” dan data sekunder melalui wawancara dengan nelayan dan masyarakat sekitar. Data indeks ekologi dianalisis menggunakan dengan indeks keragaman Shannon-Weiner (H’), indeks dominansi (C), dan indeks keseragaman (E), sedangkan data jenis nekton dan status konservasi dianalisis secara deskriptif. Komunitas spesies akuatik di perairan kawasan Sungai Unda dan Pantai Jumpai diperoleh sebanyak 26 spesies dalam 21 famili yang didominasi oleh Kepala Timah (Aplocheilus panchax) dan sepat rawa (Trichogaster trichopterus) untuk komunitas nekton, sedangkan Natica sp untuk komunitas Makrozoobenthos. Indeks ekologi pada komunitas akuatik adalah Nilai Indeks Diversitas Shannon-Weiner (H’) sebesar 2,98 (Sedang), Indeks kekayaan (R) sebesar 3,95 (Sedang), dan Indeks Kemerataan (E) sebesar 1,21 (Tinggi). Persentase perbandingan komunitas akuatik tertinggi diperoleh oleh komunitas Makrozoobenthos yaitu sebesar 53% sedangkan spesies nekton yaitu sebesar 46%. Status konservasi menunjukkan sebanyak 13 spesies termasuk dalam kategori LC (Least Concern) sebanyak 12 spesies termasuk kategori NE (Not Evaluated), dan 1 spesies termasuk dalam kategori VU (Vulnerable).
