Abstract

Penelitian dilakukan untuk mengetahui perbedaan morfometrik ikan H. Hoevenii jantan dan betina di Desa Langgam dan Tambak Sungai Kampar menggunakan metode survei dengan jumlah sampel sebanyak 60 ekor ikan jantan dan 60 ekor ikan betina di masing-masing lokasi penelitian. Ikan H. hoevenii jantan di desa Langgam memiliki kisaran panjang total 118-214 mm dan betina 129-223 mm sedangan kisaran H. hoeveniii jantan pada Desa Tambak 140-231 mm dan betina 130-270 mm. Hasil uji t menunjukkan terdapat beberapa perbedaan antar karakter H. hoevenii jantan dan betina di Desa Langgam dan Tambak yaitu karakter panjang standar, panjang predorsalm panjang preanal, panjang prepelvic, panjang prepectoral, panjang sirip adiposa, panjang duri pectoral, jaral setelah adiposa, lebar kepala, kedalaman kepala, dan diameter mata.

Abstract

Tapah fish (Wallago leerii) is a fish with high economic value in Riau Province. Molecular research on W. leerii is very important to do. This study aims to determine the molecular characteristics of W. leerii from Riau Province based on the Cytochrome b gene. The universal primer Cytochrome b is used for the Polymerase Chain Reaction (PCR) process. The PCR result is a partial Cytochrome b gene with a length of 373 bp. Multiple alignments were performed on nucleotide sequences of the Cytochrome b gene of W. leerii from river of Tapung and Indragiri Riau with the cytochrome b gene of other fish from Genbank and analyzed using the MEGA program version 6.0. Phylogenetic construction using the Cytochrome b gene can distinguish W. leerii from river of Tapung and Indragiri Riau, with other species.Keywords:AlignmentsMolecularGenBank

Abstract

Sungai Tangkerang merupakan anak sungai Sail yang rentan terjadi pencemaran, yang disebabkan oleh berbagai aktivitas penduduk di sekitar sungai. Berdasarkan kondisi itu, dilakukan pemantauan kualitas sungai menggunakan plankton yang peka terhadap perubahan lingkungan. Penelitian ini bertujuan untuk mengetahui struktur komunitas plankton sebagai bioindikator kualitas perairan Sungai Tangkerang. Pengambilan sampel plankton menggunakan metode purposive sampling. Sampel diambil di bagian hulu, tengah, dan hilir sungai, lalu dilakukan identifikasi dan analisis data. Hasil penelitian menunjukkan komposisi kelas terbanyak diperoleh kelas Cyanophyceae, Euglenophyceae, dan Chlorophyceae. Spesies dengan kelimpahan tertinggi adalah Oscillatoria sp. Kelimpahan yang didapatkan pada stasiun 1 sebesar 2.133 ind/L, stasiun 2 2.233 ind/L, dan stasiun 3 1.133 ind/L. Kelimpahan plankton di tiga stasiun tergolong dalam perairan oligotrofik hingga mesotrofik. Nilai keanekaragaman tertinggi didapatkan stasiun 1 dengan (1,77), sedangkan yang terendah pada stasiun 2 (0,77). Nilai keanekaragaman yang didapat menunjukkan bahwa Sungai Tangkerang tercemar sedang hingga berat. Nilai dominansi tertinggi terdapat pada stasiun 2 bernilai 0,63, sedangkan yang terendah 0,22 pada stasiun 2. Nilai keseragaman terendah bernilai 0,4 pada stasiun 2 dan yang tertinggi pada stasiun 3 dengan nilai 0,77.

Abstract

The floodplain areas in Sumatra play a crucial ecological and sociological role for aquatic life and surrounding communities. However, this ecosystem faces serious threats from anthropogenic activities such as land conversion into palm oil plantations, infrastructure development (dams), and industrial pollution. This article conducts a literature review regarding the diversity of migratory fish in various floodplain rivers in Sumatra. The review results indicate that the fish community in these areas is dominated by the potamodromous fish group. The Cyprinidae family was found to have the highest number of species. Conservation data show the presence of species with concerning statuses, including an Extinct (EX) status for Chitala lopis and Endangered (EN) for Pangasianodon hypophthalmus, which correlates with massive habitat degradation. This information is expected to support conservation efforts for sensitive species and maintain connectivity between river ecosystems.
