Bottom Soil Quality in Ponds for Culture of Catfish, Freshwater Prawn, and Carp in Thailand

Wudtisin, Idsariya (2006-05-15)

Bottom soil samples were collected from 42 catfish (Clarias hybrid) ponds, 40 freshwater prawn (Macrobrachium rosenbergii) ponds, and 18 carp (Puntius spp.) ponds in Thailand. The ponds ranged from 1 to 30 years in age. ...

Consequences of Decreased Water Temperature Caused by Aerator-Induced Evaporation on Growth of Pacific White Shrimp Litopenaeus vannamei in Ponds

Abdelrahman, Hisham A. (2016-07-25)

Two studies were performed related to water temperature in aquaculture ponds. The first study evaluated the influence of aeration on evaporation and water temperature in ponds, and compared the effects of daytime and ...

Effect of Ammonia Nitrogen on Production and Haemolymph of Pacific White Shrimp (Litopenaeus vannamei) Cultured in Low Salinity Ponds in Greene County, Alabama

Pratipasen, Piyajit (2014-07-24)

Water temperature, pH, and concentration of total ammonia nitrogen were measured on 12 sampling date in summer 2013 in eight shrimp ponds on an inland, low-salinity shrimp farm in Alabama. Shrimp haemolymph samples also ...

Effect of Sodium Nitrate Treatment on Water and Sediment Quality in Laboratory and Pond Studies

Chainark, Suwanit (2008-12-15)

Sodium nitrate (NaNO3) has been widely used in shrimp aquaculture ponds as a fertilizer, a water quality enhancer and a bottom soil oxidant. This study was conducted to determine whether or not treatment with sodium nitrate ...

Effects on Water Quality of Additional Mechanical Aeration in the Waste-Treatment Cells in Split-Pond Aquaculture Systems for Hybrid Catfish Production

Jescovitch, Lauren (2017-04-20)

Split-pond aquaculture is a new, innovative system for intensification of pond aquaculture in the southeastern USA. Split ponds have a fish cell and a waste cell, approximately 20% water surface area and 80% water surface ...

Effluent Water Characterization of Intensive Tilapia Culture Units and its Application in an Integrated Lettuce Aquaponic Production Facility

Abdul Rahman, Sami (2010-10-29)

In an intensive aquaculture project, effluent water characterization from three systems were evaluated (biofloc, polygyser and opposing flows). There were no differences in the mineral additions to the water per unit of ...

Effluents from an Aquaculture Research Station and Stream Water Quality

Soongsawang, Suthira (2010-01-07)

Lower Station of the E. W. Shell Fisheries Center discharges into Saugahatchee Creek. Ponds of the Fish Genetics Research Unit and the Aquaculture Production Research Unit are the main sources of anthropogenic pollution ...

Equilibrium Concentrations of Major Cations and Total Alkalinity in Laboratory Soil-Water Systems

Li, Li (2010-11-05)

Three kinds of soils and four kinds of water were used to prepare laboratory soil-water mesocosms. Soil-water mesocosms were prepared containing 5-cm deep layers of soil and 21 L of water from each of the four sources. ...

Erosion Control and Removal of Suspended Soil Particles in Ponds: Evaluation of Geofabric Liners and Chemical Coagulants

Saengrungruang, Puttitorn (2012-07-17)

In an experiment conducted at the E. W. Shell Fisheries Center, Auburn, Alabama, three ponds each were lined with a permeable geotextile with 0.090-mm opening sizes, a permeable geotextile with 0.355-mm opening sizes, or ...

Evaluation Of Flavor Of Pacific White Shrimp Penaeus Vannamei Cultured In Low Salinity Water

Le, Phuong Thuy (2011-08-15)

Water quality variables and phytoplankton were monitored in five ponds with low-salinity water (2-3 ppt) for culture of Pacific white shrimp (Pennaeus vannamei) at a farm in West Alabama from August to October. Shrimps ...

An Evaluation of Nursery Techniques and Feed Management During Culture of Marine Shrimp Litopenaeus vannamei

Zelaya, Oscar (2005-12-15)

The use of indoor shrimp nurseries is often encouraged, especially prior to intensive and super-intensive shrimp culture. Potential benefits in subsequent grow out include; better control of stock inventory, better ...

Fate, Transport, and Environmental Availability of Cu(II) Applied in Catfish Aquaculture Ponds and Enhanced Immobilization of Soil-bound Lead Using a New Class of Stabilized Iron Phosphate Nanoparticles

Liu, Ruiqiang (2007-05-15)

Copper sulfate has been the most commonly used algaecide for about a century in the U.S. to control the off-flavor problem caused by blue-green algae in channel catfish (Ictalurus punctatus) ponds. In 2001, the ~80,000 ...
