Summary
Berdasarkan tabel 1 di atas tahapan kegiatan usaha pembesaran ikan gabus haruan dalam karamba jaring tancap dari persiapan sampai panen dijelaskan sebagai berikut: 1. Persiapan Persiapan yang dilakukan pembudidaya ikan gabus haruan di Desa Bangkau yaitu dengan melakukan pengecekan kelengkapan karamba jaring tancap dan memperbaiki karamba jaring tancap jika ada yang rusak, membersihkan lokasi penempatan karamba jaring tancap, setelah pengecekan dan perbaikan selesai dilakukan baru kemudian karamba jaring tancap diturunkan ke sungai atau perairan rawa sekitar rumah. 4. Pemeliharaan Pemeliharaan meliputi dua tahap, yaitu pada tahap pertama benih yang berukuran kecil dipelihara selama 3 bulan sampai ukuran fingerling pada net tancap yang diletakkan di bawah rumah yang terhindar dari sinar matahari dan air hujan langsung untuk menghindari perubahan kualitas air yang ekstrim yang dapat menyebabkan kematian pada ikan. Tahap pemeliharaan selanjutnya ikan uang sudah mulai besar yang berumur 3 bulanan dipindahkan ke tempat yang terbuka, dan net tancap dibuat dua lapis supaya lebih kuat, kemudian seluruh permukaan net tancap diberikan tanaman eceng gondok untuk mengurangi panas yang terlalu tinggi dan air hujan tidak langsung mengenai permukaan air, juga dimaksudkan untuk menambah pasokan oksigen dalam media pemeliharaan sehingga mengurangi dampak yang ekstrim akibat perubahan kualitas air, hal ini juga diyakini pembudidaya dapat mengurangi penyakit korengan yang seringkali menyerang ikan peliharaan. Eceng gondok juga termasuk tumbuhan air yang bersifat phytoremediasi, yaitu jenis tumbuhan air yang dapat melakukan remediasi, menyerap dan atau mengubah jenis-jenis polutan tertentu yang bersifat racun dan mencemari sehingga dengan adanya tumbuhan eceng gondok ini kondisi kualitas air di perairan menjadi lebih baik
