Descriptive Method

Vannamei shrimp species look for lunch and dinner. These properties need to be known related to the amount of feed and frequency of feeding to be given. Because wasted feed is expensive and can reduce water quality, optimizing feeding practices is an important issue in shrimp culture management. The use of some ANCOs is intended to monitor feed consumption and estimate feed adjustments. So it is necessary to conduct research on the growth and graduation of vannamei shrimp (Litopenaeus Vannamei) with the feeding tray (ANCO) system in Av 8 Lim Shrimp Organization (LSO) in Sumbawa Regency. The method used in this research is descriptive method, namely research based on reality and the facts of the situation as it is. The results showed that the amount of feed every week or sampling is always different, this is because the amount of feed adjusted to the addition of shrimp growth every sampling. Addition and reduction of feeding is adjusted to the results of checking feed consumption on ANCO, adding the amount of feeding is done if when checking ANCO there is no feed left. Reduction in the number of gifts is done if when checking ANCO still left feed. In the 8th sampling the amount of feed decreased to 38 kg, this was due to the first partial harvest. In the 10th sampling is the lowest amount of feeding which is 30 kg, this is due to the second partial harvest, but in the 11th sampling the number of feeding again increased so that the shrimp could grow to its maximum potential during panentotal.

Pada kegiatan ini, empat tambak budidaya digunakan sebagai tempat pembesaran udang vaname (Litopenaeus vannamei). Parameter yang diukur meliputi parameter fisika dan kimia yaitu suhu, kecerahan, pH, oksigen terlarut, salinitas, amonia, dan alkalinitas; sedangkan performa pertumbuhan organisme budidaya dilihat dengan cara menghitung tingkat kelulushidupan (survival rate) udang pada akhir pemeliharaan, efisiensi konsumsi pakan melalui perhitungan FCR, dan laju pertumbuhan spesifik udang (SGR) dengan menghitung ABW (Average Body weight) dan ADG (Average Daily Growth) udang. Hasil penelitian menunjukan bahwa secara keseluruhan kisaran kualitas air yang diperoleh masih dalam keadaan layak untuk kegiatan budidaya dan bahkan Tambak 3 dan 4 menunjukkan kisaran optimum untuk kualitas air budidaya, sedangkan untuk parameter performa pertumbuhan, pada Tambak 3 dan 4 diperoleh nilai SR lebih dari 80 %, dan Tambak 1 dan 2 mempunyai SR di bawah 70 %. Selain itu, nilai FCR berada di bawah 1.7 pada tambak 3 dan 4, sedangkan pada Tambak 1 dan 2 nilainya lebih dari 1.7. Terakhir untuk nilai SGR, Tambak 3 dan 4 juga menunjukkan presentasi yang bagus jika dibandingkan Tambak 1 dan 2. Secara komprehensif, dapat disimpulkan bahwa penerapan sistem pemeliharaan dengan menggunakan sistem flok pada Tambak 3 dan 4 meningkatkan performa kualitas air dan hasil produksi dibandingkan pada Tambak 1 dan 2.                                                                 AbstractThe aim of this study was to monitor water quality in vaname culture pond and compare the application of different rearing culture system and feeding variations. Four ponds culture were used as vaname (Litopenaeus vannamei) growth place. Measured parameters include physical and chemical factors such as temperature,brightness, pH, DO, salinity, ammonia, and alkalinity, while growth shrimp performance showed by SGR, SR and FCR. The research result of the water quality parameters show an adequate range values for all of the ponds and good enough for shrimp growth, and especially an optimum range value presented in pond three and four. Survival rate (SR) both pond 3 and 4 exhibit a good presentation that is more than 80%, whereas pond 1 and 2 were just less than 70% of SR value. The specific growth rate (SGR) presents also a good presentation in Pond 3 and 4 rather than pond 1 and 2. Based on the feed consumption, pond 1 and 2 show high FCR that is more than 1.7 while pond 3 and 4 present smaller FCR value which is less than 1.7. Finally, it could be concluded that application of floc in culture rearing system of pond 3 and 4 increase water quality and production value than pond 1 and 2.

The elevated NH3-N and NO2-N pollution problems in mariculture have raised concerns because they pose threats to animal health and coastal and offshore environments. Supplement of Marichromatium gracile YL28 (YL28) into polluted shrimp rearing water and sediment significantly decreased ammonia and nitrite concentrations, showing that YL28 functioned as a novel safe marine probiotic in the shrimp culture industry. The diversity of aquatic bacteria in the shrimp mariculture ecosystems was studied by sequencing the V4 region of 16S rRNA genes, with respect to additions of YL28 at the low and high concentrations. It was revealed by 16S rRNA sequencing analysis that Proteobacteria, Planctomycete and Bacteroidetes dominated the community (>80% of operational taxonomic units (OTUs)). Up to 41.6% of the predominant bacterial members were placed in the classes Gammaproteobacteria (14%), Deltaproteobacteria (14%), Planctomycetacia (8%) and Alphaproteobacteria (5.6%) while 40% of OTUs belonged to unclassified ones or others, indicating that the considerable bacterial populations were novel in our shrimp mariculture. Bacterial communities were similar between YL28 supplements and control groups (without addition of YL28) revealed by the β-diversity using PCoA, demonstrating that the additions of YL28 did not disturb the microbiota in shrimp mariculture ecosystems. Instead, the addition of YL28 increased the relative abundance of ammonia-oxidizing and denitrifying bacteria. The quantitative PCR analysis further showed that key genes including nifH and amoA involved in nitrification and nitrate or nitrite reduction significantly increased with YL28 supplementation (p < 0.05). The supplement of YL28 decreased the relative abundance of potential pathogen Vibrio. Together, our studies showed that supplement of YL28 improved the water quality by increasing the relative abundance of ammonia-oxidizing and denitrifying bacteria while the microbial community structure persisted in shrimp mariculture ecosystems.
