STATUS INTRODUKSI IKAN DAN STRATEGI PELAKSANAAN SECARA BERKELANJUTAN DI PERAIRAN UMUM DARATAN DI INDONESIA

Abstract

Masuknya jenis ikan asing berpotensi merubah keseimbangan pada perairan umum daratan, dan di Indonesia gejala ini sudah mulai terlihat. Makalah ini bertujuan untuk membahas lebih lanjut tentang perkembangan introduksi ikan asing, strategi pelaksanaan intoduksi dan berbagai dampaknya terhadap komunitas ikan asli perairan di Indonesia. Penelitian dilakukan melalui penelusuran dan studi pustaka tentang: sejarah kegiatan introduksi ikan yang dilakukan ke Indonesia, jenis-ikan introduksi ikan di Indonesia dan kegiatan introduksi ikan yang telah dan dilakukan di Indonesia beserta dampaknya. Verifikasi lapangan dilakukan pada tahun 2011 di beberapa danau dan waduk antara lain Danau Sentani, Danau Kerinci, Danau Matano dan Waduk Riam Kanan. Data yang terkumpul ditabulasi dan dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa introduksi ikan asing dilakukan di Indonesia sebelum tahun 1900. Introduksi ikan yang telah dilakukan selama ini, lebih banyak dilakukan tanpa melalui kajian ilmiah yang mendalam dan telah terbukti mengakibatkan hilang atau berkurangnya populasi ikan asli atau endemik serta menjadi agen pembawa penyakit.
