Abstract

Pratama et al, 2018. The Effect of Different C/N Ratio in for Biofloc of Formation Culture Media to the Growth and Survival Rate of Juvenile Climbing Perch (Anabas testudineus). JLSO 7(1): Climbing perch fish resources still have a problem due to this fish is still obtained only through capture and also the growth of climbing perch fish is slow. The solutions to increase the growth of the climbing perch fish is by applying biofloc technology for climbing perch fish culture. The purpose of this research was to know the effect of different C/N ratio on the growth of climbing perch fish (Anabas testudineus) juvenille with biofloc farming system. This research used a completely randomized design consist of four treatments and three replications. The treatments were without molase (P0), molase with C/N ratio 15 (P1), C/N 20 (P2) and C/N ratio 25 (P3). The results showed that C / N ratio 20 was the best treatment with absolute length of growth of 1.33 cm, absolute growth of weight 1.92 g, survival rate of 99.17% and feed efficiency 138.06%.

Summary

BAHAN DAN METODE

Penelitian ini dilaksanakan di Laboraturium Budidaya Perairan, Program Studi Budidaya Perairan, Fakultas Pertanian Universitas Sriwijaya. Alat yang digunakan dalm penelitian ini adalah akurium, bak tandon, blower dan instalasi, botol sampel, DO meter, pH meter, scoopnet, mistar, termometer dan timbangan digital. Bahan yang digunakan dalam pelaksanaan penelitian ini adalah benih ikan betok (panjang 4+0,5 cm), probiotik komersil, molase, garam krosok, kapur dolomit dan pakan komersil dengan protein 30%. Perlakuan dengan pemberian molase sebagai sumber karbon dalam penelitian adalah sebagai berikut: P0 = (kontrol) tanpa pemberian molase P1 = Pemberian molase dengan rasio C/N. Persiapan Penelitian Persiapan penelitian meliputi wadah dan persiapan air pemeliharaan. Wadah pemeliharaan yang digunakan sebanyak 12 unit. Persiapan air pemeliharaan sebagai media awal dalam membuat bioflok. Penambahan garam 3 kg/m3, dolomit 100 gram/m3, molase 100 ml/ m3 dan probiotik 10 ml/m3 yang berfungsi sebagai starter (Suprapto dan Samtafsir 2013)
