Comparison of Automated versus Manual Monitoring of Levels of Dissolved Oxygen in Aquaculture Ponds
Automated water quality monitoring systems can be used to help maintain optimal levels of dissolved oxygen (DO) in aquaculture systems by continuously monitoring oxygen concentrations and immediately turning on aerators to supplement oxygen if a critical limit is reached. This study compares differences in water quality maintenance under operation schemes using manual and automated water qualit...
متن کاملMeasuring Dissolved Oxygen Concentration in Aquaculture
(DO) is considered the most important water quality variable in fish culture. In the broadest sense, however, dissolved oxygen concentration is no more important than other environmental variables because any factor that is outside the range tolerated by fish can cause stress or death. What makes dissolved oxygen concentration so important in intensive fish culture is the speed with which it ca...
متن کاملmathematical modeling of dissolved oxygen in fish ponds
a mathematical model was developed to predict the effects of wind speed, light, ph, temperature, dissolved carbon dioxide and chemical oxygen demand (cod) on dissolved oxygen (do) in fish ponds. the effects of organic feeds, aeration and fish activity were added to the model developed by kayombo et al. for waste stabilization ponds (ecological modeling 127(2000): 21-31) to reflect the situat...
متن کاملBlue Crab Aquaculture in Ponds
North Carolina’s Blue Crab Fishery As North Carolina’s number one fishery, blue crabs, Callinectes sapidus, are part of an important industry for numerous coastal communities. The fishery supports commercial fishermen, dealers, gear providers and processors throughout the year. Fluctuations in landings have led to concerns over crab populations and the livelihood of the commercial crabbers they...
متن کاملThe Effects of Dissolved Oxygen on Fish Growth in Aquaculture
Commercial aquaculture is growing worldwide except in Africa where production is still low. With fisheries reaching a stagnating phase, the world and more so Africa will have to look to aquaculture in the future to provide fish products that will likely be needed. In view of this, a study on water quality management was done which specifically looked at the effects of dissolved oxygen saturatio...
