Rotifer Brachionus Plicatilis

<p><em>Brachionus</em><em> plicatilis</em> is a widely used as natural feed in hatchery. Characteristics of rotifers as biocapsule can improve the quality of rotifers in a practical way. <em>Bacillus</em><em> </em>sp. is capable of improving the nutrition rotifers to produce vitamins, food detoxication or through enzymatic activity such as protease, lipase, and amylase. This research aimed at observing the influence of the enrichment length of <em>Bacillus </em>sp. on the quality of nutrition and growth of rotifers. The research container was a <em>polyearbonate</em> vessel of one ton volume which contained <em>Nannochloropsis</em> sp. with the density of 10<sup>5</sup> cell/mL, it was then scattered with rotifer with the density of 1,000 ind./mL. The types of bacteria used were <em>Bacillus subtilis</em>, <em>B. pumilus</em> and <em>B. licheformis</em> with the density of 2x10<sup>10</sup> cfu/g. The experiments tried with different enrichment length were A = 0 hour, B = 5 hours, C = 10 hours and D = 10 hours with triplicate. As the comparing data, rotifer culture experiment was carried out with <em>Nannochlorophsis </em>sp.as the control. The number of containers were 24 which consists of 12 for threatment and 12 pieces as control. Variables measured were proximate to each treatment and the growth of rotifers. The result of the research revealed the enrichment length of rotifers with <em>Bacillus</em> sp. has significantly (P<0,05) towards increased protein, crude fiber, ash, BETN, and growth. Optimum enrichment time was obtained at 5 hours.</p> <p>Key words: rotifers, <em>Bacillus</em>, enrichment period, proximate</p> <p> </p> <p>ABSTRAK</p> <p><em>Brachionus plicatilis</em> merupakan pakan alami yang banyak digunakan dalam pembenihan.

Feeding Protocol

The study tested a new feeding protocol to find out the best program using cheap and available products to enhancement the mass culture and the nutritional value of B. plicatilis. The feeding regime was six artificial treatments formulated from dried yeast (Saccharomyces cervisiae) with sucrose sugar and yeast with molasses in different concentrations. Additionally, a live Cyclotella sp. had been applied as supplementary food to each treatment and as independent treatment (control). B. plicatilis was cultured in small scale to find the best food regime and technique to apply it in the large one. B. plicatilis attained its highest density in the small scale culture (370 Ind.ml1 ) with T1 (30 % yeast, 70 % sugar and Cyclotella sp.) at the 12th day, while the highest population growth rate (PGR) (0.65) was calculated at the 9th day. According to the analysis of variance (ANOVA) and PGR, T1 had been applied in the large scale culture. B. plicatilis samples were composed of 51.6% total protein with 16 amino acids and 33.01% total lipid with 19 identified fatty acids. The study concluded that the treatment (T1) is a suitable diet for enrichment the mass culture and the nutritional value of B. plicatilis.

Secondary feeding with commercial lipids enrichments such as the microencapsulated diets Diet A (33.42±3.00%) and Diet B (55.88±3.5%) compared with the marine yeast type product Diet C(8.59±1.0%) as a method of increasing the total lipids and ω-3 PUFA content of rotifers, hence enhancing their nutritional value as live feed prey for fish larvae in hatcheries. The total lipids the rotifers was affected analogous to the levels of these components in the feeds showing its maximum percentage uptake within 4 hours from the enrichment (20.27±3.52, 26.64±3.91, 11.31±2.30 respectively). There was not any significant toxicity to the animals due to the diets during the 16 hours experiment. The DHA/EPA for Diet A(1.31), Diet B(0.42) and Diet C(absent) as well as the DHA/EPA/ARA ratios for Diet A(10.70 ± 1.60 / 8.18 ± 1.10 / 2.08 ± 0.20), Diet B(6.20 ± 2.30 / 14.60 ±1.00 / 1.12 ± 0.40) and Diet C (0 / 5.14 ± 3.40 / 1.30 ± 1.10) indicates that Diet A is closer to the suggested DHA/EPA/ARA optimal value 10/5/1 for marine fish larval growth.
