Vannamei shrimp (Litopenaeus vannamei) production continues to decline due parasitic attacks on ponds in North Gorontalo Regency. Ectoparasites are one of the factors that can cause failure cultivation vannamei shrimp. This study aims determine type ectoparasites, intensity, and prevalence cultured traditional The sampling research was carried out at five stations. this taken random 5 plots tot...

Shrimp farming in Indonesia was initially dominated by Windu Shrimp, but along with the decline tiger shrimp production due to disease, one of things that determines success businesses, both traditional and intensive, is pest disease control. Diseases generally occur parasitic infections cause parts shrimp's body be injured, so other diseases such as fungi, bacteria, viruses will more easily ex...

As the primary consumers in aquatic organisms, zooplankton play an important role ecosystems. It is valuable for management and researchers to have insight into responses of community patterns environmental factors. In this study, RDA variation partitioning analysis were adopted determine factors affecting abundance biomass, as well relative importance different The findings reveal that TN (tot...

Nghiên cứu này kiểm tra hiệu quả của việc sử dụng công nghệ bể phản ứng sinh học dạng mẻ (SBR) trong xử lý nước thải chung cư. Hiệu suất các chỉ tiêu ô nhiễm tương ứng: BOD5 (90 - 95%), COD (93 97%), TSS (83 Amoni (92 98%), Tổng Nito Độ đục (85 màu (62 75%). Hệ vi SBR được quan sát và cho thấy có 09 loại nguyên động vật chiếm ưu thế với tỷ lệ xuất hiện như sau: Vorticella 26%, Aspidisca 22%, Li...

The repertoire of microeukaryotes in the human gut has been poorly explored, mainly in individuals living in northern hemisphere countries. We further explored this repertoire using PCR-sequencing and culture in seven individuals living in four tropical countries. A total of 41 microeukaryotes including 38 different fungal species and three protists were detected. Four fungal species, Davidiell...
