Abstract
The purpose of this study is to analyze the biological and ecological aspects of Labiobarbus festivus in Barumun river. Research is exploratory by determining the reseach station using the determination method (purposive sampling). Data analysis using Microsoft Excel version 2013. Research has shown that the most biological class size of L. festivus is small. The lenght of L. festivus weight relationship values b > 3 or is positive allometric. The highest population of L. festivus is station 3 with 1,9 individuals/m2 and relative weight condition is < 100. The ecological aspect : the fulton condition factor < 1 shows that this fish is thin and the chemical physical factors that have been carried out are temperatures of 26-28 ̊C, water depth from 118-144 cm, current speed is 0,02 – 0,04m/s, water brightness 35-56 cm, total suspended density (TSS) with numbers 20-100 mg/L, water pH is at 7,21 -8,02, dissolved oxygen (DO) at 4.47 -7,25 mg/L, Barumun river COD at 12,44 – 25,16, phosphate at < 0,003 and nitrates 2,28 – 2,74 mg/L. Keywords : Biological aspects, Ecological aspects, Labiobarbus festivus, Barumun river ===================================================== Tujuan penelitian ini menganalisis aspek biologi dan ekologi Labiobarbus festivus di Sungai Barumun. Penelitian bersifat eksploratif dengan penentuan stasiun penelitian menggunakan metode penentuan (purposive sampling). Analisa data menggunakan Microsoft Excel versi 2013. Hasi penelitian menunjukan aspek biologi bahwa kelas ukuran L. festivus paling banyak adalah ukuran kecil. Hubungan panjang berat L. festivus nilai b > 3 atau bersifat allometrik positif. Kepadatan populasi L. festivus tertinggi yaitu Stasiun 3 dengan 1,9 individu/m2 dan faktor kondisi berat relatif < 100 . Aspek ekologi yaitu faktor kondisi fulton L. festivus < 1 menunjukan bahwa ikan kurus dan faktor fisika kimia yang telah dilakukan yaitu suhu 26-28 ̊ C, Kedalaman air dari 118-144 cm, kecepatan arus yaitu 0,02 – 0,04 m/s, Kecerahan air 35-56 cm, total kepadatan tersuspensi (TSS) dengan angka 20-100 mg/L, pH air berada pada angka 7,21-8,02, oksigen terlarut (DO) pada angka 4,47-7,25 mg/L, COD Sungai Barumun dengan angka 12,44- 25,16, fosfat yaitu < 0,003 dan nitrat 2,28-2,74 mg/L.
