In-Pond Raceways
In general, water cannot be economically pumped through raceways; it must flow through them by gravity. The need for large volumes of good quality water is the principal reason raceways have been limited to sites with large springs. Most raceway culture in the U.S. is with coldwater species such as trout and is based around locations with high volume, cold springs, or creeks. A few raceway syst...
متن کاملHeavy metals contaminant evaluation in sediments of Khour-e-Musa creeks, northwest of Persian Gulf
Surface sediments contamination to heavy metals was evaluated in eight creeks of Mahshahr coastal waters (north-west of the Persian Gulf) from October. 2005 to November 2006. Sediments were collected seasonally by Peterson grab and the concentrations of heavy metals were measured using voltammetry and polarography methods. The range and the mean concentrations obtained in mg/kg were 15.03-35.16...
متن کاملEffect of solar light on the decrease of microbial contamination in facultative stabilization pond
One of the indexes of stabilization pond is the presence of coliform bacteria in water and wastewater. This study aimed to determine the effect of solar light on coliform variations in stabilization pond. In this experimental study, the effect of light, pH (<7, 7.1–8, 8.1–9), and temperature (10 ºC and 30 ºC) on facultative stabilization pond was studied for six months. The sampling was accompl...
متن کاملImpact of population and latrines on fecal contamination of ponds in rural Bangladesh.
A majority of households in Bangladesh rely on pond water for hygiene. Exposure to pond water fecal contamination could therefore still contribute to diarrheal disease despite the installation of numerous tubewells for drinking. The objectives of this study are to determine the predominant sources (human or livestock) of fecal pollution in ponds and examine the association between local populat...
متن کاملField-testing Enterococcus Faecalis for Bacterial Source Tracking
A waste stabilization pond was suspected of causing fecal contamination to Holt Branch, a tributary of Juniper Creek, near Byron, Georgia. We used ribotyping, a genotypic (DNA-based) bacterial source tracking (BST) method, to match Enterococcus faecalis isolates from Holt Branch and the waste stabilization pond. Fecal enterococci in the effluent from the waste stabilization pond averaged 13,863...
