Abstract
Elongaria.orientalis adalah salah satu kerang air tawar yang terdistribusi di Indonesia.Sungai Barumun, sungai ini mengalir di sepanjang kabupaten Labuhanbatu Selatan. Tujuan penelitian ini untuk mengetahui Bioekologi E. orientalis.Adapun metode yang digunakan dalam penelitian ini yaitu metode purposive sampling.Kelimpahan E. orientalis yang tertinggi terdapat pada stasiun 3 dengan jumlah 26 spesies. Pola pertumbuhan dari tiga stasiun dikategorikan stasiun 1 dan 3 allometrik negatif dengan stasiun 1 nilai stasiun 1 nilai b = 2,961 dengan koefisien determinasi ( R2 ) sebesar R² = 0.942, sedangkan Stasiun 3 nilai b = 2,847 dengan koefisien determinasi (R2 ) sebesar R² = 0,757, sedangkan stasiun 2 allometrik positif nilai b = 3,325, dengan koefisien determinasi (R2 ) sebesar R² = 0.885,. Suhu perairan sungai Barumun terendah terdapat pada stasiun 3 dengan suhu 260C, stasiun 3 juga menjadi sungai terdalam dengan kedalaman 144 cm .Korelasi faktor fisika kimia perairan sungai Barumun yang sangat kuat adalah Kedalaman (0,900), Kekeruhan (0,932), Nitrat (0,997) TSS (0,999), dan Pb(0,999) dikategorikan korelasi kuat. layak untuk pertumbuhan E. orientalis. Kata Kunci: E. orientalis, Sungai Barumun, purposive sampling, Kelimpahan, Pola Pertumbuhan. =================================================================================================== Elongaria.orientalis is one of the freshwater mussels distributed in Indonesia.Barumun River, this river flows along the South Labuhanbatu Regency. The purpose of this study is to determine the Bioecology E. Orientalist.The method used in this research is purposive sampling method. Abundance Of E. the highest Orientalist is located at Station 3 with a total of 26 species. The growth pattern of the three stations categorized as Station 1 and Station 3 allometric negative with Station 1 value Station 1 value b = 2.961 with coefficient of determination ( R2 ) of R2 = 0.942, while Station 3 value b = 2.847 with coefficient of determination (R2) of R2 = 0.757, while Station 2 allometric positive value b = 3.325, with coefficient of determination (R2 ) of R2 = 0.885,. The lowest temperature of the Barumun River is at Station 3 with a temperature of 260C, Station 3 is also the deepest river with a depth of 144 cm . The correlation of physical and chemical factors of Barumun river waters which is very strong is depth (0.900), turbidity (0.932), nitrate (0.997) TSS(0.999), and Pb (0.999) categorized as strong correlation. worthy of growth E. Orientalist. Keywords: E. Orientalist, Barumun River, purposive sampling, abundance, growth patterns.
