Rotifer Brachionus Plicatilis

The rotifer Brachionus plicatilis was cultured with powdered dried Chlorella in treatment 1, live or fresh cultured Chlorella in treatment 2, and baker's yeast in treatment 3. All the jars under three treatments were stocked with B. plicatilis at the initial density of 10 individuals per ml. The water temperature, air temperature, pH and dissolved oxygen were within the suitable range for B. plicatilis culture. The highest population densities of B. plicatilis in treatments 1, 2 and 3 were 60000, 50000 and 30000 (individual/L), respectively. The powered dried Chlorella was comparable with live Chlorella and may be used successfully as a feed for B. plicatilis. DOI: 10.3329/bvet.v27i2.7559 Bangl. vet. 2010. Vol. 27, No. 2, 91-98

Randomized Design

One of larvae feed can be used is Brachionus plicatilis but necessary an enrichment for review adding nutritional values of the Brachionus plicatilis. Some phytoplankton frequently used type food by Brachionus plicatilis between lay Tetraselmis sp., Skeletonema costatum, Chlorella sp., Dunaliella salina and Spirulina sp. (Isnansetyo And Kurniastuty, 1995). In this time, many parlors seed microalgae replace with yeast bread, beside that yeast bread serves as a probiotic too (Winasuria, 1993). This study aims to determine the effect feeding review form a combination of yeast bread and Chlorella sp. against population growth and protein content of Brachionus plicatilis. The research method used is an experimental method with completely randomized design as design of Experiments. The treatment used is a combination of yeast and Chlorella sp. with different period, that was treatment A (Chlorella sp. 100%), treatment B (Chlorella sp. 25% and 75% baker's yeast), treatment C (Chlorella sp. 50% and 50 % of baker's yeast), treatment D (Chlorella sp. 75% and 25% baker's yeast), each treatment was repeated 5 times. The main parameter observed is population growth, growth rate and protein content. The supporting parameters observed parameter is water quality. Data analysis using variant analysis (ANOVA) and to review the best treatment, Duncan's Multiple Range Test performed. Results Provision combination of baker's yeast and Chlorella sp. with term certain showed significant differences (p<0,05) against population growth Brachionus plicatilis. The highest population growth are in treatment D  and the lowest are in treatment B. For a review feeding of Brachionus plicatilis preferably using Chlorella sp. with 1,125x106 density cells / ml and 0,0005 grams of baker's yeast.

The Difference

ABSTRAKThis study aims to determine the best dose of bakers yeast in culture Brachionus plicatilis. The research was conducted in July-September 2015 in the Mandiri Laboratory of BTN Puri Meninting West Lombok District. This experiment  uses a completely randomized design ( CRD ), which consists of 6 treatments and repeated 3 times , in order to obtain 18 units of trial that treatment A : without feed , treatment B : feed Nannochloropsis spp., treatment C : 7.5 mg/L, treatment D : 15.0 mg/L , treatment E : 22.5 mg/L , and treatment F : 30.0 mg/L. The results showed that the difference in the level of baker's yeast significantly affect the population growth of Brachionus plicatilis, which obtained the highest population density in the yeast dose of 30.0 mg/L of 90 individuals/mL Key word : bakers yeast, population growth, Brachionus plicatilisABSTRACT Penelitian ini bertujuan untuk mengetahui dosis ragi roti yang terbaik  dalam kultur Brachionus plicatilis. Penelitian dilaksanakan pada bulan Juli - September 2015  di Laboratorium Mandiri BTN Puri Meninting Kabupaten Lombok Barat. Penelitian ini menggunakan  Rancangan Acak Lengkap (RAL) yang terdiri dari 6 perlakuan dan diulang sebanyak 3 kali, sehingga diperoleh 18 unit percobaan yaitu  perlakuan  A : tanpa pakan, perlakuan  B : pakan Nannochloropsis spp.,  perlakuan C : 7,5 mg/L, perlakuan D : 15,0 mg/L, perlakuan  E :  22,5 mg/L,  dan perlakuan  F : 30,0 mg/L. Hasil penelitian menunjukan bahwa perbedaan dosis ragi roti berpengaruh nyata terhadap pertumbuhan populasi Brachionus plicatilis, dimana kepadatan populasi tertinggi diperoleh pada dosis ragi 30,0 mg/L yaitu 90 individu/mL Kata kunci : ragi roti, pertumbuhan populasi,  Brachionus plicatilis,
