Appropriate adoption techniques in aquaculture contribute to food security. The study appraised the functionality of aquacultural Oshimili South Local Government Area Delta State, Nigeria using approaches. objectives were ascertain level management techniques, examine pond types adoption, assess fish farmers’ technological needs and identify constraints affecting adoption. A quota sampling tech...

A biorefinery is ideal because it can combine many processes to produce multiple bio-products from organic solid waste. Moreover, in view of socially rising energy demands and biodiversity conservation, contributed as a sustainable strategic tool for the emerging circular bio-economy. In this research objective was study some techniques increase productivity Lanchester’s freshwater prawn earthe...

This study aimed at assessing the effect of packaging materials and preservatives on nutrient composition fish was carried out using 864 live Clarias gariepinus with an average weight 226g acquired from earthen pond a farm in Omi-Adio, Ibadan, Nigeria. The experiment conducted 4 × 3 11 factorial (4 preservatives, storage periods). protein content decreased consistently 77.538 (0days after smoki...

Earthen waste lagoons are commonly used to store liquid wastes from concentrated animal feeding operations. The fate of ammonium (NH) and nitrate (NO) was studied in the vadose zone below earthen-clay dairy farm waste lagoons using three independent vadose zone monitoring systems. The vadose zone was monitored from 0.5 to 30 m below land surface through direct sampling of the sediment porewater...

An understanding of the changes of the rammed earth temperature of earthen ruins is important for protection of such ruins. To predict the rammed earth temperature pattern using the air temperature pattern of the monitoring data of earthen ruins, a pattern prediction method based on interesting pattern mining and correlation, called PPER, is proposed in this paper. PPER first finds the interest...

Fully polarimetric Synthetic Aperture Radar (polSAR) data analysis has wide applications for terrain and ground cover classification. The dynamics of surface and subsurface water events can lead to slope instability resulting in slough slides on earthen levees. Early detection of these anomalies by a remote sensing approach could save time versus direct assessment. We used L-band Synthetic Aper...

Wastewater from abattoirs in some countries is disposed of into water bodies without adequate removal contaminants. Therefore, the use wastewater fish production could pose a serious risk for humans, and other aquatic organisms due to possible transfer pathogenic bacteria culture environments. The aims present study were assess levels individual microorganisms different tissues common carp dete...

Archaeal 16S rRNA gene compositions and environmental factors of four distinct solfataric acidic hot springs in Kirishima, Japan were compared. The four ponds were selected by differences of temperature and total dissolved elemental concentration as follows: (1) Pond-A: 93°C and 1679 mg L(-1), (2) Pond-B: 66°C and 2248 mg L(-1), (3) Pond-C: 88°C and 198 mg L(-1), and (4) Pond-D: 67°C and 340 mg...
