<p>Disinfection and nutrient enrichment prior stocking of  post larvae in the pond will be affected on the growth and composition of microbe.  Attention should be taken to some factors related to deterministic and stochastic factors of aquaculture environment  in order to develop microbe community.  This study was performed to determine effect of sucrose and probiotic supplementation to shrimp culture pond on water quality profile and population dynamic on shrimp culture media.  The treatments were supplementation of sucrose as carbon source, probiotic, and sucrose + probiotic into 25 L culture medium containing white shrimp, <em>Litopenaeus vannamei</em>.  Shrimp were fed commercial diet containing 30% protein by 5% body weight every day.  The result of study showed that bacterial population was increased by increasing time of shrimp rearing.  Increased of bacterial population was contrary to DO value.   Bacteria grew was heterotrop and vibrio that its intensity varied during experiment.  Supplementation of sucrose supported proliferation of bacteria including heterotrop, probiotik and vibrio groups.  Specifically, interaction between probiotic bacteria and vibrio was also found.  The presence of probiotic bacteria showed a negative impact on vibrio population.  Further, development of bacteria in general was also implicated to fluctuation of ammonia concentration in pond.</p> <p>Keywords: carbon, sucrose, probiotic, white shrimp, <em>Litopenaeus vannamei</em></p> <p> </p> <p>ABSTRAK</p> <p>Kegiatan disinfeksi dan pengkayaan nutrien sebelum penebaran PL akan mempengaruhi pola pertumbuhan dan komposisi mikroba di tambak. Hal-hal yang perlu diperhatikan dalam pengembangan komunitas mikroba adalah faktor-faktor <em>deterministic</em> dan <em>sthocastic</em> masing-masing lingkungan budidaya. Penelitian ini dilakukan untuk mengetahui pengaruh pemberian bahan berkarbon (sukrosa) dan probiotik di tambak terhadap profil kualitas air serta dinamika populasi pada perairan budidaya. Pada penelitian ini dilakukan penambahan sumber karbon (sukrosa), penambahan probiotik dan penambahan sukrosa + probiotik pada masing-masing wadah yang berisi 25 liter air dan udang Vanamei, <em>Litopenaeus vannamei</em>. Pakan yang diberikan berupa pellet komersial dengan kadar protein 30% setiap hari sebanyak 5% dari biomassa awal. Dari hasil penelitian ini diketahui bahwa populasi bakteri pada media budidaya meningkat seiring dengan bertambahnya waktu pemeliharaan. Peningkatan jumlah populasi bakteri ini diikuti oleh semakin menurunnya nilai DO secara umum. Selain bakteri heterohof, tumbuh juga bakteri golongan <em>Vibrio</em> dengan persentase kemunculan yang berbeda pada setiap perlakuan. Penambahan sukrosa dalam media budidaya mendukung proliferasi bakteri secara umum, heterotrof, probiotik dan golongan <em>Vibrio</em>. Secara spesifik, timbul juga interaksi antara bakteri probiotik dengan bakteri <em>Vibrio</em>. Tumbuhnya bakteri probiotik berimplikasi negatif terhadap populasi <em>V</em><em>i</em><em>brio</em>. Selain itu pertumbuhan bakteri secara umum juga berimplikasi terhadap fluktuasi kadar amonia perairan.</p> <p>Kata kunci : karbon, sukrosa, probiotik, udang vaname, <em>Litopenaeus vannamei</em></p>

The efficacy of povidone iodine as a surface disinfectant was assessed in white shrimp (Litopenaeus vannamei) eggs and larvae. Eggs and nauplii were exposed to povidone iodine 20 ppm for 20 seconds. Culture-based method and Terminal Restriction Fragment Length Polymorphism (T-RFLP) were used to monitor the total number of bacteria and diversity of the bacterial community associated with shrimp eggs and larva at each developmental stage. Povidone iodine reduced the total culturable bacteria, especially Vibrio, on eggs and nauplii, as well as the total bacteria in the whole community as estimated by T-RFLP results. Povidone iodine also reduced the diversity of bacterial community and altered the evenness of phylotypes distribution suggesting that the use of povidone iodine as a surface disinfectant in shrimp aquaculture should be reconsidered.

Sediment oxygen consumption level is an indicator of mineralization procces intensity and indicator of microorganism activity in the substrate, and also a description of dissolved oxygen consumption or utilization in a water body. This study aimed to evaluate factors of sediment quality which influenced sediment oxygen consumption level. The study was conducted at the experimental pond installation of Research Institute for Coastal Aquaculture (RICA), in Punaga, Takalar Regency, South Sulawesi, using two units of 4000m2 intensive ponds with density of 50ind./m2. Rearing period was approxi-mately in 4months. Pond management was carried out in accordance with standard operating pro-cedures. Homogeneity between experimental units was approached by the uniformity of pond management including pond preparation, shrimp seed management, feed management,and water management. Sediment quality variables measured were redox potential, pH, total organic matter, sediment oxygen consumption, total bacteria, and production aspect. The results showed that the factors which have close relationship with the sediment oxygen consumption were redox potential, organic matter, and total bacteria. The model could be used to predict the sediment oxygen con-sumption on white shrimp pond with the following regression equation Y=  0.0000496 + 0.00025 organic matter + 0.00037 total bacteria - 0.00000948 potential redox with R2 = 0.847.Keywords: sediment oxygen consumption, sediment quality, pond, Litopenaeus vannamei
