Simpulan
Kegiatan KJA di Waduk Cirata memberikan pengaruh terhadap karakteristik fisika-kimia perairan dan menyebabkan eutrofikasi dengan masalah pertumbuhan makrofita yang berlebih. Tingginya bahan organik karena kegiatan KJA yang didukung dengan curah hujan dan cuaca mendung yang tinggi menyebabkan terbentuknya pola hipoksia yang semakin dangkal.
Saran
Terkait dengan kedalaman DO minimum bagi pertumbuhan ikan maka aktivitas budidaya ikan sebaiknya dilakukan dengan sistem jaring ganda dengan kedalaman 3 m pada jaring pertama dan 7 m pada jaring kedua. Mekanisme pemberian pakan pada aktivitas budidaya dapat dilakukan dengan menggunakan sistem feeding tray, yaitu dengan menebarkan pakan ikan di tempat khusus sehingga menahan dan mengurangi sisa pakan yang terbuang ke lingkungan.
Kegiatan KJA di Waduk Cirata harus dikurangi sesuai dengan daya dukung perairan. Hal ini dibutuhkan ketegasan dari pemerintah setempat dan penawaran alternatif konversi kegiatan KJA bagi petani budidaya. Pengerukan sedimen dapat dilakukan sebagai usaha perbaikan kualitas air untuk jangka pendek dan untuk tujuan jangka panjang diperlukan usaha yang terkait dengan ketegasan pemerintah. Ketegasan pemerintah terkait operasi KJA diantaranya adalah diberlakukannya standar usia operasi KJA dan tidak diikuti dengan perpanjangan ijin operasi, adanya ijin khusus operasi KJA dan adanya kontrol dan patroli secara periodik dari petugas setempat.
