| Abstract: | Budidaya menghasilkan sejumlah besar limbah, terdiri dari metabolisme oleh-produk, makanan sisa, materi feses dan residu dari masukan profilaksis dan terapeutik, mengarah pada penurunan kualitas air dan wabah penyakit. Bioremediasi, aplikasi mikroba / enzim untuk tambak, adalah metode yang sedang digunakan untuk meningkatkan kualitas air dan menjaga kesehatan dan stabilitas sistem akuakultur. Bioremediasi melibatkan mineralisasi bahan organik menjadi karbon dioksida, memaksimalkan produktivitas primer yang merangsang produksi udang, nitrifikasi dan denitrifikasi untuk (1) menghilangkan kelebihan nitrogen dari tambak dan (2) mempertahankan beragam dan stabil masyarakat kolam dimana patogen dikeluarkan dari sistem dan spesies diinginkan mendapatkan didirikan. Selain dari bahan organik merendahkan (detritivorous) bakteri heterotrofik, nitrifikasi, bakteri denitrifikasi dan fotosintesis umumnya digunakan dalam bioremediasi. |

| Abstract: | Aquaculture farms, particularly in Southeast Asia are facing severe crisis due to increasing incidences of White Spot Syndrome Virus (WSSV). Actinomycetes have provided many important bioactive compounds of high prophylactic and therapeutic value and are continually being screened for new compounds. In this communication, the results of a study made to determine the effectiveness of marine actinomycetes against the white spot disease in penaeid shrimps are presented. Twenty-five isolates of actinomycetes were tested for their ability to reduce infection due to WSSV among cultured shrimps. When these actinomycetes were made available as feed additives to the post-larvae of the black tiger shrimp Penaeus monodon for two weeks and challenged with WSSV, the post challenge survival showed variations from 11 to 83%. However, six isolates have shown to be the most potential candidates for further study. |
