Abstract

Rasbora spilotaenia merupakan salah satu ikan endemik Pulau Sumatera. Habitat alami ditemukan di Aek Kanan dan masuk wilayah administratif Kabupaten Padang Lawas Utara. Hingga saat ini belum ada data dan informasi terkait aspek bioekologi Rasbora spilotaenia yang dilaporkan dari wilayah Kabupaten Padang Lawas Utara. Tujuan penelitian adalah untuk mengetahui aspek bioekologi Rasbora spilotaenia dan status konservasi di IUCN. Penelitian yang dilakukan bersifat eksploratif dengan penentuan titik stasiun pengamatan secara purposive sampling. Ikan ditangkap menggunakan 2 mata jaring (mesh size) berbeda, yakni ukuran ⅟₂ dan ¼ inci. Sampel ikan yang tertangkap diukur panjang total dan berat, serta dihitung jumlah jantan dan betina. Analisis data menggunakan statistik deskriptif. Berdasarkan data distribusi frekuensi kelas ukuran panjang paling banyak ditemukan 6,5 - 7,8 cm (8 individu), dan paling sedikit 5,1 - 6,4 cm (0), nisbah kelamin antara jantan dan betina (1:2), kepadatan populasi tertinggi pada stasiun 2 (0,91 individu/100m2 ), terendah pada stasiun 1 (0,06 indvidu/100 m2 ), hubungan panjang berat dengan nilai R2 (0,9562), dan parameter suhu rata-rata (27oC), kecerahan (111,33 cm), kedalaman (1,01 m), arus (0,46 m/detik), pH (5,67), dan DO (6,6 mg/L). Disimpulkan bahwa aspek bioekologi Rasbora spilotaenia di Aek Kanan masih stabil terhadap kondisi populasi, serta habitat alami masih mendukung kehidupan ikan, namun untuk status konservasi perlu sedikit diperhatikan. Kata Kunci: Bioekologi, Ikan Endemik Sumatera, Rasbora Spilotaenia. ===================================================================================================== Rasbora spilotaenia is one of the endemic fishes of Sumatra Island. Its natural habitat is found in Aek Kanan and is included in the administrative area of North Padang Lawas Regency. Until now there has been no data and information related to the bioecological aspects of R. spilotaenia reported from the North Padang Lawas Regency area. The aim of the study was to determine the bioecological aspects of R. spilotaenia and its conservation status in IUCN. The research conducted was exploratory with the determination of the observation station point by purposive sampling. Fish were caught using 2 different mesh sizes, namely sizes, ⅟₂ and ¼ inch. Samples of fish caught were measured in total length and weight, and the number of males and females were counted. Data were analysed using descriptive statistics. Based on the frequency distribution data, the most length class was found to be 6.5-7.8 cm (8 individuals) and the least was 5.1 -6.4 cm (0), the sex ratio between males and females (1:2), the highest population density at Station 2 (0. 91 individuals/100 m2) and lowest at Station 1 (0.06 individuals/100 m2), length weight relationship with R2 value (0.9562), and parameters of mean temperature (27oC), brightness (111.33 cm), depth (1.01 m), current (0.46 m/s), pH (5.67), and DO (6.6 mg/L). It was concluded that the bioecological aspects of R. spilotaenia in Aek Kanan are still stable towards Keywords: Bioecology, Fish Endemic to Sumatera, Rasbora spilotaenia.
