Pond water aeration systems
, 1997
"... During the past decade, pond aeration systems have been developed which will sustain large quantities of fish and invertebrate biomass. These aeration systems are modifications of standard wastewater aeration equipment. Aeration-performance testing has been important in selecting design features to ..."

to provide cost-effective yet efficient aquaculture pond aerators. Paddlewheel aerators and propeller-aspirator-pumps are probably most widely used. Amounts of aeration vary from as little as 1–2 kW ha−1 in some types of fish culture to as much as 15 or 20 kW ha−1 in intensive culture of marine shrimp
Effect of Aeration on Water Quality, Fish Growth and Survival in Aquaculture Ponds
, 2005
"... Abstract.-Fingerlings of Labeo rohita, Cirrhinus mrigala, Hypophthalmichthys molitrix and Ctenopharyngodon idella (average weight 32.0 gram) were cultured in six brick lined (26'x12'x6') ponds for a period of six months. The stocking ratio was 7:4:4:3, respectively and the stocking d ..."

density of each pond was 2508 fish/acre. Three of the six ponds served as aerated ponds and other three as non-aerated ponds. Aeration was done with the help of 1/3 Hp vertical pump. Fish in each pond were fed with 20% protein diet @ 3% body weight. The ponds were fertilized with cattle manure (@ 500 kg
The Performance of Two Phase Flow Systems in Pond Aeration
"... Abstract: Aeration is the process by which the area of contact between water and air is increased, either by natural methods or by mechanical devices. Proper aeration can make considerable improvements in a pond ecosystem. This paper investigates pond aeration by two phase flow systems such as high ..."

Design and Control Strategy of Diffused Air Aeration System
"... Abstract-During the past decade, pond aeration systems have been developed which will sustain large quantities of fish and invertebrate biomass. Dissolved Oxygen (DO) is considered to be among the most important water quality parameters in fish culture. Fishponds in aquaculture farms are usually loc ..."

Total Carbon Concentrations in Pond Bottom Soils
, 1993
"... Abstract.—Aerated ponds did not accumulate as much carbon in bottom soils as control ponds. Application of urea to manured ponds did not accelerate carbon loss from bottom soils. When ponds were drained for fish harvest, appreciable carbon was eroded from the surface layers of bottom soil. Further d ..."

Effect of oxygen management on culture performance of channel catfish in earthen ponds
- North American Journal of Aquaculture
, 2005
"... Abstract.—Aeration allows for higher feeding rates and increased production of channel catfish Ictalurus punctatus in intensive and semi-intensive aquaculture systems. However, the effect of specific dissolved oxygen (DO) concentrations on various production parameters remains unknown. The purpose o ..."

Evaluation of Canny Edge Detection and Muti-Threshold Segmentation Technique for Precise Mapping and Inventory of Aquaculture Ponds in Coastal Areas
"... The demand for a pond-based aquaculture system has increased over the past years and it resulted into uncontrolled competition of fish farmers and commercial pond owners. This system of fish production has rapidly increase the dynamic changes occurring in our coastal areas. One significant change is ..."

Purification Performance and Production of a Re-circulating Pond Aquaculture System Based on Paddy Field
, 2012
"... Abstract: Developing improved aquaculture systems with a more efficient use of water and less environmental impact is becoming a crying need. A re-circulating aquaculture system consisting of paddy field and fish pond is a new culture mode due to aquaculture combing with agriculture. The present st ..."

Integration of intensive and semi-intensive aquaculture: concept and example
- Thai Fish. Gaz
, 1990
"... An experiment on integrated walking catfish-tilapia culture was conducted for 5 months. The walking catfish were stocked at 400 and 800 fish/cage in two 4-m3 nylon cages, which were suspended in each of two 250-m2 earthen ponds. Sex-reversed male tilapia (Oreochromis niloticus) were reared at 1 fish ..."

in the pond water showed that water quality was suitable for both tilapia and catfish growth. Total catfish and tilapia production was approximately 100 and 140 kg/pond, respectively. The experiment demonstrated that tilapia can efficiently use catfish waste and maintain desirable water quality.
Oxygen transfer in marsh-pond-marsh constructed wetlands treating swine wastewater
"... Oxygen transfer efficiencies of various components of the marsh-pond-marsh (M-P-M) and marsh-floating bed-marsh (M-FB-M) wetlands treating swine wastewater were determined by performing oxygen mass balance around the wetlands. Biological oxygen demand (BOD) and total nitrogen (TN) loading and escapi ..."
Abstract

and escaping rates from each wetland were used to calculate carbonaceous and nitrogenous oxygen demands. Ammonia emissions were measured using a wind tunnel. Oxygen transfer efficiencies of the aerated ponds were estimated by conducting the ASCE standard oxygen transfer test in a tank using the same aeration
