Abstract

Tujuan penelitian ini adalah untuk melihat efek pencemaran perairan terhadap ikan melalui observasi preparat histologis insang ikan nila (Oreochormis niloticus L). Penelitian dilakukan pada Bulan Januari 2017. Jenis penelitian ini adalah penelitian kualitatif menggunakan metode observasi langsung terhadap struktur insang ikan nila. Teknik pengambilan sampel adalah purposive sampling pada 3 lokasi di Danau Maninjau. Pembuatan preparat menggunakan metode paraffin dan pewarnaan Haematoxylin-Eosin di Laboratorium Balai Veteriner, Bukittinggi. Hasil pengamatan struktur histologi insang menunjukkan adanya perubahan struktur histologi berupa hipertropi, fusi lamella, kerusakan struktur lamella hingga hilangnya struktur lamella. Dapat disimpulkan bahwa efek pencemaran perairan dapat mengakibatkan perubahan terhadap struktur histologi insang ikan nila.
