However, intensive culture system of white shrimp could increase the risk of disease outbreak. The application of sinbiotic may provide solution to the problem. This study was aimed to evaluate the effectiveness of the use of technical sinbiotic on the survival and growth of white shrimp in ponds. This study consisted of four treatments; treatment K (control), treatment A (probiotic 0.5% and prebiotic 1%), treatment B (probiotic 1% and prebiotic 2%), and treatment C (probiotic 2% and prebiotic 4%). The results showed that administration of sinbiotic had no significant differences on survival rate, growth rate, feed conversion ratio, size, and biomass of shrimp (P&gt;0.05). However, based on analysis of business, sinbiotic A provided higher profits to the farmer (Rp10.230) compared to other symbiotic treatments and control.</p><p class="BasicParagraph"> </p><p class="BasicParagraph">Keywords: <em>Litopenaeus vannamei</em>, sinbiotic, technical media</p><p class="BasicParagraph"><strong> </strong></p><p class="BasicParagraph"><strong><br /></strong></p><p class="BasicParagraph" align="center"><strong>ABSTRAK</strong></p><p class="BasicParagraph"><strong> </strong></p><p class="BasicParagraph">Permintaan terhadap udang vaname <em>Litopenaeus vannamei</em> yang semakin meningkat membuat sistem budidaya udang sebaiknya menggunakan sistem budidaya intensif.

ABSTRACTThis study was conducted to evaluate the digestibility of biofloc meal collected from catfish culture as a feed raw material for Pacific white shrimp Litopenaeus vannamei diet. A basal feed with 43% crude protein content was used as a control diet and mixed with 2% of binders and 0.5 % of Cr2O3 as a marker for digestibility. The experimental diets were made by mixing 67.5% of the basal diet with 30% of biofloc meal, 2% of binders and 0.5 % of Cr2O3. Nine units of glass tanks (90 cm ×40 cm× 35 cm) filled with 100 L seawater were used as the experimental culture units. White shrimp with an average body weight of 5.61 ± 0.09 g was randomly distributed to each experimental tank at a density of 20 shrimp/tank. The feed was offered at a level of 5% shrimp biomass per day at a frequency of four times a day. The results showed that the dry matter digestibility of feed with 30% biofloc meal in shrimp were similar to that of the reference diet. However, protein and fat digestibility of feed containing biofloc meal were considerably higher than those of the reference diet. Feeding shrimp with 30% biofloc meal diet resulted in higher survival and specific growth rate and lower feed conversion ratio than those of the control. The digestibility of bioflocs dry matter, protein and lipid in Pacific white shrimp obtained in this study were 54.9%, 76.3% and 79.3%, respectively.Keywords: biofloc, digestibility, catfish, shrimp  ABSTRAKPenelitian ini dilakukan untuk mengevaluasi kecernaan tepung bioflok yang diambil dari media pemeliharaan ikan lele sebagai bahan pakan udang vaname Litopenaeus vannamei. Pakan yang mengandung kadar protein 43% digunakan sebagai pakan control dan dicampur dengan 2% binder dan 0.5% Cr2O3 sebagai marker untuk kecernaan. Pakan perlakuan dibuat dengan mencampurkan 67.5% pakan control dengan 30% tepung bioflok, 2% binder dan 0.5% Cr2O3. Penelitian menggunakan sembilan unit akuarium (90 cm ×40 cm ×35 cm) yang diisi 100 L air laut. Udang vaname dengan bobot rata-rata 5.61 ± 0.09 g ditebar secara acak pada setiap akuarium perlakuan pada kepadatan 20 ekor/akuarium. Pakan diberikan dengan tingkat pemberian pakan 5% biomassa per hari sebanyak empat kali sehari. Hasil penelitian ini menunjukkan bahwa kecernaan pakan dengan 30% tepung bioflok tidak berbeda nyata dengan pakan acuan. Namun kecernaan protein dan lemak pakan yang mengandung tepung bioflok terlihat lebih tinggi daripada pakan kontrol. Pemberian pakan dengan tepung bioflok sebanyak 30% juga menghasilkan tingkat kelangsungan hidup, laju pertumbuhan spesifik udang dan rasio konversi pakan yang lebih baik daripada udang yang diberi pakan kontrol. Kecernaan bahan, protein dan lemak tepung bioflok pada udang yang didapat dalam penelitian masing-masing adalah 54.9%, 76.3% dan 79.3%.Kata-kata kunci: bioflok, ikan lele, kecernaan, udang

The study explored the possibility of integrating the grey mullet Mugil cephalus (Linnaeus, 1758) along with Pacific white shrimp  Litopenaeus vannamei (Boone, 1931) in floating cage culture in Godavary Estuary, India. Post-larvae (PL 12) of L. vannamei (3 lakhs nos.), were acclimatised and nursed in five hapas for 28 days at a density of 3333 nos. m-2, with survival of 60%. L. vannamei juveniles having mean weight of 0.86 g, stocked at a density of 1060 nos. m-2, were cultured along with and without pre-stocked M. cephalus, in three floating cages each. Six thousand fry of M. cephalus (mean length 4.17 cm; mean weight 1.22 g) were stocked in three cages at uniform density of 23.5 nos. m-3, three months prior to stocking of L. vannamei. Shrimps were fed commercial pellets @ 3-8% of body weight, four times daily and harvested after 68 days. Fishes were fed with pelleted feed and after five months attained mean length of 23.7 cm and mean weight of 274.1 g. Survival was 46.4% and the average production obtained was 250.2 kg. At harvest, L. vannamei in monoculture system attained mean weight of 13.3 g and in the mixed culture system, average weight obtained for the shrimps was 13.5 g. Survival, feed conversion ratio (FCR) and production of L. vannamei from monoculture were 64.7%, 2.0 and 258.9 kg and from mixed culture 76.8%, 1.6 and 311.5 kg respectively. Daily weight increment and specific growth rate (SGR) of L. vannamei was 0.18 g and 4.06 for monoculture and 0.19 g and 4.01 for mixed culture, resepectively. Feed conversion, survival and production of L. vannamei were significantly (p<0.05) better in mixed culture, confirming technical superiority of mixed culture over monoculture.

Functional feed supplemented with alternative-economic nutrient sources (protein, carbohydrates, lipids) and probiotics are being considered in shrimp/fish aquaculture production systems as an option to increase yield and profits and to reduce water pollution. In this study the probiotic potential to formulate functional feeds have been evaluated using four dietary treatments: Treatment 1 (B + Bs); Bacillus subtilis potential probiotic strain was supplemented to a soybeanmeal (SBM)—carbohydrates (CHO) basal feed. Treatment 2 (B + Bm); Bacillus megaterium potential probiotic strain was supplemented to the same SBM-CHO basal feed. In Treatment 3 (B); SBM-CHO basal feed was not supplemented with probiotic strains. Treatment 4 (C); fishmeal commercial feed (FM) was utilized as positive control. Feeding trials evaluated the survival, growth, and food conversion ratio and stress tolerance of juvenile Litopenaeus vannamei (Boone) Pacific white shrimp. Best overall shrimp performance was observed for animals fed with Treatment 1 (B+Bs); additionally, stress tolerance and hemolymph metabolites also showed the best performance in this treatment. SBM-CHO basal feed not supplemented with probiotic strains (B) presented smaller growth and lower feed conversion ratio (FCR). Shrimps fed with the fishmeal commercial feed (C) presented the lowest stress tolerance to high ammonia and low oxygen levels. Specifically selected B. subtilis strains are recommended to formulate functional and economical feeds containing high levels of vegetable; protein and carbohydrates as main dietary sources in L. vannamei cultures.

This research aimed to evaluate the production performance of white shrimp Litopenaeus vannamei with super-intensive culture on different rearing densities. The research was conducted at PT. Dewi Laut Aquaculture, Cikelet, Garut, West Java. As many of 8 ponds were used and divided into 2 groups based on the stock density of shrimp, 550 ind/m2 and 650 ind/m2, and reared for 99 days. The results showed that super-intensive shrimp culture at the density of 550–650 ind/m2 potentially produced shrimp with average body weight ranged from 15.91–19.31 g, survival rate 62.67–87.95%, growth 0.16 to 0.20 g/day, FCR 1.35–1.66, and productivity reach 5.55–9.19 kg/m2. There were no significant differences between the two stocking densities in body weight, growth, and feed conversion performance, while ponds with higher rearing density had better survival and productivity than ponds with lower rearing density. L. vannamei cultured at a density of 650 ind/m2 produces the best performance and most feasible to be applied in super-intensive white shrimp cultivation. Keywords: Litopenaeus vannamei, super-intensive, high-density, production performance   ABSTRAK Penelitian ini bertujuan untuk mengevaluasi kinerja produksi udang vaname pada sistem super- intensif dengan padat penebaran berbeda. Penelitian dilaksanakan di tambak PT. Dewi Laut Aquaculture, Cikelet, Garut, Jawa Barat, menggunakan 8 petak tambak. Tambak dibagi menjadi 2 kelompok, masing-masing 4 petak tambak dengan padat tebar udang 550 ekor/m2 dan 4 petak tambak lainnya dengan padat tebar 650 ekor/m2 dengan masa pemeliharaan 99 hari. Hasil penelitian menunjukkan bahwa budidaya udang vaname pada sistem super-intensif dengan padat tebar 550–650 ekor/m2 dapat menghasilkan udang dengan bobot rata-rata berkisar antara 15.91–19.31 g, sintasan 62.67–87.95%, pertumbuhan 0.16–0.20 g/hari, konversi pakan (FCR) 1.35–1.66, dan produktivitas mencapai 5.55–9.19 kg/m2. Tidak ada perbedaan nyata antara kedua padat penebaran pada kinerja bobot, pertumbuhan harian, dan FCR; sementara tambak dengan kepadatan tinggi memiliki nilai sintasan dan produktivitas yang lebih tinggi dari tambak dengan kepadatan rendah. Padat penebaran 650 ekor/m2 menghasilkan kinerja produksi terbaik dan paling layak untuk diaplikasikan dalam budidaya udang vaname super-intensif.
