dc.description.abstract | Research of The Diversity And Distibution of Fishes And Connection With Water
Quality of Siais Lake In The South Tapanuli Resindence conducted in November
2010- March 2011. Samples taken from five observation stations, where at each
station conducted thirty replication of sampling. The Method used in samples with
Purposive Random Sampling. Samples were taken by using fishing net then identified
that was done in Laboratory of Natural Resources and Environment Processing,
Biology Department, Mathematic and Science Faculty, North Sumatera University.
From the result showed the diversity of fishes consists of 5 orders, 8 families, 12
genera and 12 species. Fishes diversity index ranged from 2.04 to 2.27, the overall
Diversity of fishes is low. The calculation of Morisita Distribution Indeks showed
that prawn distributed in group. The analysis Pearson correlation, penetration of
light, DO, BOD5, fosfate TDS, TSS has the positive correlated to the diversity of
fishes, while pH, COD, organic substrate, temperature, nitrat E. Coli has the
negative correlated to the diversity of fishes. From the physical of chemical and
biolgical, have not been polluted waters of Lake Siais and still within the normal
range according to the quality standard of water quality class I by PP 82 of 2001
and the method Storet. | en_US |
dc.description.abstract | Penelitian tentang Keanekaragaman dan Distribusi Ikan Serta Hubungannya Dengan
Kualitas Air Danau Siais Kabupaten Tapanuli Selatan dilakukan pada bulan
Nopember 2010 - Maret 2011. Sampel diambil dari lima stasiun pengamatan, pada
setiap stasiun dilakukan tiga puluh kali ulangan pengambilan sampel. Metode yang
digunakan dalam pengambilan sampel adalah dengan Purposive Random Sampling.
Sampel ikan diambil dengan menggunakan jala tebar kemudian dilakukan
identifikasi di Laboratorium Pengelolaan Sumber Daya Alam dan Lingkungan
Departemen Biologi, Fakultas Matematika dan Ilmu Pengetahuan Alam Universitas
Sumatera Utara. Dari hasil penelitian menujukkan keanekaragaman ikan terdiri dari
5 ordo, 8 famili, 12 genus dan 12 species. Indeks Keanekaragaman ikan berkisar
antara 2,04-2,27, secara keseluruhan keanekaragaman ikan pada perairan Danau
Siais adalah rendah dan Indeks Distribusi Morisita menunjukkan bahwa ikan
berdistribusi secara berkelompok. Dari hasil analisis korelasi Pearson menunjukkan
bahwa intensitas cahaya, DO, BOD5, PO4, TDS, TSS, berkolerasi positif (searah)
terhadap keanekaragaman ikan sedangkan pH, COD, substrat, suhu NO3, E.coli dan
penetrasi cahaya berkolerasi negatif terhadap keanekaragaman ikan. Dari sifat fisik
kimia dan biologi yang didapat, perairan Danau Siais belum tercemar dan masih
berada dalam kisaran normal yang sesuai dengan baku mutu kualitas air kelas I
berdasarkan PP 82 Tahun 2001 dan Metode Storet. | en_US |
