Sulfate-based alginate polysaccharide (SAP) is a novelty marine prebiotic. To investigate the beneficial effects of SAP in Pacific white shrimp (Litopenaeus vannamei) fed low-fishmeal diets, six diets (whole fishmeal group: FM; replacement with cottonseed protein concentrate and supplementary groups: SAP0, SAP1, SAP2, SAP3, SAP4) were formulated for 56 days. The results showed that SAP2 SAP3 gr...
Aquaculture combines techniques for breeding and harvesting aquatic organisms used in shrimp production. It is important as a source of income generating foreign exchange the regions where it practiced. However, timely detection diseases continues to be great challenge aquaculture fisheries In recent years, Enterocytozoon hepatopenaei (EHP) has emerged major pathogen Pacific white Penaeus vanna...
—Dietary supplements have been proposed as a potential remediation strategy to counteract mineral deficiencies in low-salinity well waters (LSWW) used for shrimp culture in Alabama. Existing strategies (i.e., application of fertilizers such as K-mag and muriate of potash) are costly to farmers attempting to raise levels of potassium (Kþ) in their ponds. Previous laboratory studies using dietary...
Over the past 2 decades, shrimp aquaculture in Thailand has been impacted by white spot disease (WSD) caused by white spot syndrome virus (WSSV). Described here are results of a survey of 157 intensive shrimp farms in Chanthaburi province, Thailand, to identify potential farm management and location risk factors associated with the occurrence of WSD outbreaks. Logistic regression analysis of th...
Shrimp white spot disease (WSD), which is caused by white spot syndrome virus (WSSV), is one of the world's most serious shrimp diseases. Our objective in this study was to use an immunomagnetic reduction (IMR) assay to develop a highly sensitive, automatic WSSV detection platform targeted against ICP11 (the most highly expressed WSSV protein). After characterizing the magnetic reagents (Fe3O4 ...
Within the endemic invertebrate faunas of hydrothermal vents, five biogeographic provinces are recognized. Invertebrates at two Indian Ocean vent fields (Kairei and Edmond) belong to a sixth province, despite ecological settings and invertebrate-bacterial symbioses similar to those of both western Pacific and Atlantic vents. Most organisms found at these Indian Ocean vent fields have evolutiona...
White spot syndrome virus (WSSV), the causative virus of disease, is found in most shrimp farming areas in Iran, and it cause large economic losses to the shrimp farming industry. Shrimp aquaculture is an important industry in Iran and plays an important role in aquaculture production. The shrimp production in 2012 was more than 12000 metric tonnes and it is estimated it will reach 20000 tonnes...
The dietary crude protein requirement of penaeid shrimp is an important nutritional consideration because protein is often the major limiting nutrient for growth. In most cases, research has focused on total dietary protein levels rather than a daily requirement for protein. This research utilized three practical diets containing 16%, 32%, and 48% protein and various daily rations to estimate d...
Shrimp aquaculture is one of the growing animal industries. Breeding stocks with high disease-resistance and growth rate are of particular interest to shrimp breeders. Association studies are useful to find genetic markers for marker assisted selection of animals. Using six Litopenaeus vannamei individuals from a sample population, four single nucleotide polymorphisms (SNPs) were found in the 5...
Ž . The use of a co-extruded soybean poultry by-product meal CEPM and flashed dried poultry Ž . by-product meal FD-PBM was evaluated as replacements for fish meal in a practical diet formulated to contain 32% crude protein and 8% lipid. Each meal was substituted for menhaden Ž fish meal on an iso-nitrogenous basis and offered to juvenile Litopenaeus Õannamei mean initial . Ž wt."S.D., 0.37"0.01...
