Information Pirates or Robin Hood Heroes? Sustainability of Open Access for Public Libraries
No full textFormer URI: http://hdl.handle.net/10125/49521This poster presentation explores the sustainability of open access for public libraries and nonacademics. It presents what is already being done in the open access movement and the challenges of the sustainability of this compared with the current access model. This poster also discusses the importance of open access in public library settings in particular, and how we as professionals can work towards a more sustainable access model
Replacement of Soybean Meal with Rhizoclonium riparium Protein Concentrate in the Diet of Pacific White Shrimp Litopenaeus vannamei Postlarvae
Get PDFThe biological value of incorporating Rhizoclonium riparium var. implexum protein concentrate (RPC) meal in the diet of Pacific white shrimp Litopenaeus vannamei, postlarvae was evaluated for 60 days. Four diets were prepared: no seaweed inclusion (0%, control diet), 5.25% seaweed inclusion, 10.5% seaweed inclusion, and 15.75% seaweed inclusion with equivalent replacement rates of soybean meal at 0, 15%, 30% and 45%. Final average body weight (FABW) and weight gain (WG) of the shrimp were not significantly affected by the RPC supplementation (P>0.05) except those of shrimp fed the highest level of 15.75% RPC, which showed lower values but were statistically similar to those of the 5.25% group. Specific growth rate (SGR) and protein gained (PG) values of shrimp were not affected by the dietary RPC except those of the 15.75% group, which showed significantly lower values. Neither feed conversion efficiency (FCE) nor protein efficiency ratio (PER) showed a clear trend for graded concentration of RPC. Survival of shrimp was relatively good and statistically similar ranging from 76.0%-84.0%. In conclusion, Rhizoclonium protein concentrate can replace 30% soybean meal in the diet of Penaeus vannamei postlarvae or an equivalent of 10.5% inclusion rate without negative effects on the survival, growth, and feed conversion efficiency of white shrimp
Rapid and Sensitive Detection of Vibrio natriegens in Portunus trituberculatus with the Loop-Mediated Isothermal Amplification Test
Get PDFIn order to detect Vibrio natriegens in Portunus trituberculatus, a loop-mediated isothermal amplification (LAMP) method was developed and evaluated. In this study LAMP primers were designed to correspond to the gyrB gene sequences. With Bst DNA polymerase, the LAMP assay was completed within 100 min at 65 C in a water bath. Amplification products were observed directly with agar gel or with the naked eye after the addition of SYBR Green I. The sensitivity of the LAMP assay for the detection of V. natriegens is about 1.32×10-2 fg/mL DNA template, whereas using duplex PCR the detection of V. natriegens was possible up to 13.2 pg/mL DNA template. There were no cross-reactions with other Vibrio strains indicating a high specificity of the LAMP. The novel LAMP assay in this study can be used as a valuable, rapid, and sensitive detection tool for the detection of V. natriegens both in the laboratory and for use in commercial aquacultur
Polyculture of Sea Cucumber Holothuria scabra with Pacific White Shrimp Litopenaeus vannamei
Get PDFAn experimental study of polyculture of sea cucumber Holothuria scabra with Pacific white shrimp Litopenaeus vannamei was carried out in the laboratory. Results indicated that nutrient structure of the culture system was influenced significantly by the sea cucumber: the phosphate and nitrate concentrations were enhanced more obviously in the polyculture system (PS) than in the monoculture system (MS), but by contrast, the ammonium concentration remained low in the PS. The sulfide contents of the sediment were reduced in the PS to 10.32±1.85mg/kg, accounting for about 2/5 of that in the MS. The PS of sea cucumbers had positive effects on the growth and survival of shrimp, the specific growth rate of weight of shrimp in the PS was 2.89±0.63%/day and significantly higher than that of the MS (average 2.05±0.57%/d). Survival rate of the shrimp in PS was 79.3±22.9%, dramatically higher than that of the MS (average 64.0±17.5%). In the PS, the shrimp had no negative effect on the sea cucumbers who ingested and assimilated food residue in the sediment of the culture system with an assimilation efficiency of 42.06±10.62% for organic matter. PS of sea cucumber Holothuria scabra in the shrimp culture system had both environmental and economic benefits. This PS method could contribute to sustainable development of aquaculture in Chin
