Solar pond is a device which entraps the impinging solar radiation and stores it as thermal energy in its salty layers. Simple salt gradient solar pond consists of three basic layers: lower convective zone, non-convective zone and last is upper convective zone. In present study a simple working experimental setup of salt gradient solar pond was fabricated equipped with thermo siphon heat exchan...
The Prairie Pothole Region (PPR) is the most important waterfowl production area in North America. However, waterfowl populations there are predicted to decline because of climate-related drying of wetlands. Consequently, changes in the geographic focus of PPR waterfowl conservation have been recommended, which could have long-lasting and costly impacts. We used a 40-year dataset of pond counts...
The study was conducted to evaluate the effect of artificial feed and adding organic manures to the earthen ponds on the growth and body composition of genetically improved farmed tilapia (GIFT). A total of 160 fish were stocked in each of the two ponds for 90 days. Fish in both ponds were fed with supplementary feed containing 30% crude protein at 4% body weight. Pond 1 was fertilized using co...
A pond heat and temperature regulation (PHATR) model was designed to: (1) predict the temperature for earthen outdoor aquaculture ponds and (2) determine the size of energy transfer mechanisms affecting energy gains or losses for these ponds. The model solves a first order, no-linear differential equation using a 4th order Runge-Kutta numerical method and various input data (weather data, pond ...
Leucobacter chironomi strain MM2LB(T) (Halpern et al., Int J Syst Evol Microbiol 59:665-70 2009) is a Gram-positive, rod shaped, non-motile, aerobic, chemoorganotroph bacterium. L. chironomi belongs to the family Microbacteriaceae, a family within the class Actinobacteria. Strain MM2LB(T) was isolated from a chironomid (Diptera; Chironomidae) egg mass that was sampled from a waste stabilization...
The goal of this study was to use environmental sequencing of 16S rRNA and bop genes to compare the diversity of planktonic bacteria and archaea across ponds with increasing salinity in the Exportadora de Sal (ESSA) evaporative saltern in Guerrero Negro, Baja CA S., Mexico. We hypothesized that diverse communities of heterotrophic bacteria and archaea would be found in the ESSA ponds, but that ...
The experiment was conducted in two earthen ponds to investigate the body composition, and fatty acid profile of carps along with growth performance by using rice polish as fish feed with urea and ammonium nitrate fertilization of pond. Silver carp (Hypophthalmichthys molitrix), Rohu (Labeo rohita) and Mori (Cirrhinus mrigala) were stocked in the ratio of 1:2:1 respectively with total number of...
