Abstract
The main problem in catfish culture is high mortality and high feed conversion ratio (FCR). The aim of this study was to know the application of probiotic in catfish culture. For nursery, catfish juveniles with size of 2-3 cm was cultivated for 40 days while fish with size of 7-9 cm was cultured for 85 days in grow-out tank. All tanks were administered by probiotic during one culture cycle. Probiotic was directly given to the water and administered by feed. The results showed that survival rates of nursery and grow-out tanks were 95% and 95,8%, respectively. The FCR in the grow-out was 0.76. It can concluded that probiotic application was able to improve the survival rate and the feed conversion ratio in catfish culture.

Summary
Number x, 201x JIAT e-ISSN:2477-7951 - p-ISSN:2502-4973 mampu menambah produksi ± 170,3 ton/tahun. Kecamatan Tumpang merupakan salah satu daerah kegiatan pendederan dan pembesaran lele di Kabupaten Malang. Terdapat beberapa masalah yang dihadapi yaitu tingginya mortalitas dan tingginya rasio konversi pakan ikan lele. Salah satu upaya untuk mengatasi masalah tersebut adalah dengan mengaplikasikan probiotik pada sistem budidaya. Probiotik merupakan produk yang mampu mengontrol penyakit, meningkatkan pertumbuhan (Cruz et al 2012) [4], memproduksi enzim ekstraselular (Ray et al 2012) [14], meningkatkan system imun dan memperbaiki kualitas air (Banerjee dan Ray, 2017). Al-Dohail et al (2011) [1] menunjukkan bahwa penggunaan Lactobacillus acidophilus dapat meningkatkan kelulushidupan juvenil C. gariepinus secara signifikan. Ayoola et al (2013) [2] melaporkan bahwa pemberian probiotik Lactobacillus dan Bifidobacterium mampu meningkatkan pertumbuhan C. gariepinus. Tujuan dari studi ini adalah untuk mengetahui pemanfaatan probiotik pada pendederan dan pembesaran lele
