PENGGUNAAN BAKTERI PROBIOTIK SEBAGAI KONTROL BIOLOGI DALAM PRODUKSI MASSAL BENIH RAJUNGAN (Portunus pelagicus)

Abstract

ABSTRAKPenelitian dilakukan untuk dapal mengontrol lingkungan secara biologis dalam produksi massal melalui penggunaan bakteri probiotik serta meningt<attan keragaan pertumbuhan larva rajungan (Portunus peragicusr. peneritian menggunakan bai vorurne 4.00b riterdirengkapi dengan srstem aerasi dan suhu terkontror, ditebar zoea-1 dengan kepadatan 50 ind./L, seraira peneriian diberi pakan berupa rotifer' pakan komersiar, dan naufrius artemia. seoagar perrakuan adarah A) probiotik komersial' B) probiotik K 7, dan c) tanpa probiotik. Bakteri probrotrk diinokurasrkan ke dalam media pemeliharaan dengan kepadatan 106 cfu/ml Hasil penelitian menunlukkan bahwa stadia megalopa dapat dicapai sekitar 7-8 hari dengan pemberian bakteri K_7 (B). Femetiharaan larva rajungan pada perlakuan A dan C memerluk"n *"it, g_l O hari. Sintasan megalopa pada perlakuan A, B, dan C berlurulturut sebesar g,37%; 9,2go/a, dan 7 ,gO%. perlakuan B mienunjuikan gerakan megalopa lebih aktif. Populasi yibno spp. pada perlakuan A) mencapar 9 x 10, cfu/mL B) 6 x 10, cfu/ml, dan C) 1 ,0 x 103 cfurmr.. The main constrain ot aquaculture was insufficient of seed suppty and hgh moftalty caused by diseases infection The aim of this tial was to evaluate the effectiveness of prot:iotics to control reaing water media and growth of btue swimming crab (portunus petagicus). Tank with the volume of 4,000 liter used with aeration system aid controlled water temperature regulated by automatic water heater. zoea-1 as test animarwith stocking density of so ind./L vr'ere iared, and fed with natural and anificiarfeed rhe treatment were l, Timmeriiat prottiotic), B (probiotic K-7), and c (without probiotic). The resurt showed megaropa stage treatei with probrctic K-7 (B) was achieved within 7-B days and was achieved within faste; than the A and c treatments which needed 9-10 days. SuNival rate of megalopa stage on A, B and C were s,3t%: g,2g%: and 7'90yo respectively. Population of vibtio sp. on such treatment were A. g x 10, cfu/mL, B. 6 x 10, cfu/ mL, and C: 1.0 x 1d cfu/mL respectively.

PENGARUH PERBEDAAN WAKTU APLIKASI PROBIOTIK TERHADAP KUALITAS AIR DAN SINTASAN PASCA LARVA UDANG WINDU (Penaeus monodon)

“…Penggunaan bakteri probiotik sudah sangat meluas di hampir semua kegiatan budidaya diantaranya, pemeliharaan larva kepiting (Nogami & Maeda, 1992), larva rajungan (Susanto et al, 2005), dan budidaya artemia (Villamil et al, 2003). Pada budidaya ikan, penggunaan probiotik dijumpai pada pemeliharaan rainbow trout (Brunt & Austin, 2005;Brunt et al, 2007), ikan karper (Labeo rohita) (Kumar et al, 2006;Banerjee et al, 2007), pematangan gonad ikan hias (Ghosh et al, 2007), pemeliharaan ikan nila (Tilapia nilotica) (Aly et al, 2008a, Wang et al, 2008, larva ikan sebelah (flatfish) Senegalese sole (Makridis et al, 2008), larva gilthead sea bream (Sparus aurata, L) (Suzer et al, 2008), dan budidaya ikan kakap putih (seabass) (Rengpipat et al 2008).…”

Effect of Different Probiotic Bacteria on Survival Rate, Growth, and Production of Whiteleg Shrimp in Traditional-Plus Technology

“…Probiotic bacteria can be isolated from the sea water, sea sediment, coral, pond sediment, mangrove leaves, and macroalgae (Tjahjadi et al, 1994;Rosa et al, 1997;Haryanti et al, 2000;Muliani et al, 2003;Atmomarsono et al, 2009;Tampangallo et al, 2013). Some benefits of using probiotic bacteria are 1) safer than chemicals; 2) not pathogen to fish and shrimp; 3) unaccumulated in the foodchain; 4) easily reproduced; 5) not making resistant to pathogenic (Nogami & Maeda, 1992), swimming crab larvae (Susanto et al, 2005), brine shrimp (Villamil et al, 2003), and rainbow trout (Brunt & Austin, 2005;Brunt et al, 2007). Probiotic bacteria have also been used for tiger shrimp culture (Meunpol et al, 2003;Gunarto et al, 2006;Atmomarsono, 2008;Atmomarsono et al, 2009).…”
