Abstract

Ikan hias merupakan salah satu komoditi yang banyak diminati karena mempunyai daya tarik tersendiri baik warna, bentuk  maupun tingkah lakunya yang unik. Komet (Carassius auratus auratus) pertama kali dibudidayakan oleh masyarakat Cina pada tahun 1729. Namun pembudidaya sering menghadapi permasalahan adanya kecendrungan penurunan persentase daya tetas telur, mortalitas larva ikan yang tinggi serta warna ikan. Untuk itu maka harus dilakukan perbaikan genetik pada ikan budidaya dengan berbagai metode. Salah satunya dengan metode manipulasi kromosom, yaitu dengan cara pemberian teknik kejutan suhu panas. Sehingga penelitian ini bertujuan untuk mengetahui berapa kejutan suhu panas yang tepat pada daya tetas telur (hatching rate) dan kelangsungan hidup (survival rate) larva ikan komet( Carrasius auratus auratus ). Penelitrian ini dilaksanakan selama 2 bulan dari bulan Februari – April 2018 yang berlokasi di Balai Benih Ikan Kelobak Kepahiang, dengan alat berupa akuarium heater, blower dan bahan induk ikan komet matang gonad. Menggunakan Rancangan Acak Kelompok (RAK) dengan 4 kelompok dan 4 ulangan. K1 = Suhu 36oC, K2 = Suhu 38oC, K3 = Suhu 40oC, K4 = Suhu 42oC dan dilanjutkan dengan uji BNT. Variabel yang diamati adalah : (1) Waktu penetasan (2) Daya tetas telur (3) Kelangsungan hidup larva dan (4) Kualitas air

Abstract

The biofloc system catfish wastewater is in the form of accumulation of organic residues from feed residues, catfish manure, feed particles and bacteria and algae, because the biofloc catfish cultivation wastewater can be processed into organic fertilizer especially liquid organic fertilizer. The study used a completely randomized single factor treatment with an aerobic (A) fermentation process and Anaerobic fermentation process (B). Each treatment was repeated 8 times to obtain 16 experimental units. Furthermore, the results of the study data were analyzed by variance at the level of 5 percent. The results showed that the growth rate of catfish was very good. Where growth continues to increase the 10th day observation until the end of the study. While the content of N, P and K in the POC produced did not show a significant difference between POC fermented by Aerob and Anaerob. POC content fermented by Aerob; N = 1.645, P = 0.326 and K = 1.143 while Anaerobic fermentation; N = 2.189, P = 0.278 and K = 1.165.

Abstract

Peningkatan padat tebar pada budidaya ikan menyebabkan tingginya pengunaan pakan sehingga daya saing akan pemanfatan oksigen akan meningkat, ikan akan kekurangan oksigen sehingga pertumbuhan menjadi lambat. Daya saing pemanfatan oksigen terjadi karena banyaknya sisa-sisa feses yang menyebabkan terjadinya penumpukan amoiak yang akan diuraikan oleh bakteri dan mikroba lainnya. Dengan adanya sistem resirkulasi budidaya menggunakan kepadatan tinggi dapat dilakukan, ikan akan hidup sesuai dengan kebutuhan oksigen yang berasal dari proses difusi dari pergerakan air dan kotoran pun akan berkurang dengan penggunaan filter. Penelitian bertujuan untuk mengetahui padat tebar ikan nila (Oreochromis niloticus) yang terbaik terhadap pertumbuhan dan kelangsungan hidup ikan nila yang dibudidayakan di dalam kolam terpal dengan sistem Resirkulasi. Penelitian menggunakan Rancangan Acak Lengkap (RAL) yaitu 5 perlakuan dan 3 ulangan sehingga mendapatkan 15 unit percobaan ; P1 Padat tebar = 20 ekor/m2, P2 = 30 ekor/m2,P3 = 40 ekor/m2, P4 = 50 ekor/m2, P5 = 60 ekor/m2 dan dilanjutkan dengan Uji Polinomial Orthogonal. Hasil penelitian menunjukkan bahwa padat tebar yang berbeda berpengaruh sangat nyata (**) terhadap pertumbuhan panjang dan berat serta juga berpengaruh nyata terhadap konversi dan efesiensi pakan tetapi berbeda nyata (ns) terhadap kelangsungan hidup ikan nila (Oreochromis niloticus). Berdasarkan uji lanjut polynomial pada pengamatan berat biomassa ikan maka padat tebar yang terbaik untuk pemeliharaan ikan nila dengan sistem resirkulasi adalah 56 ekor/m2
