Alternative ingredients in practical diets for Pacific white shrimp (Litopenaeus vannamei)

Qiu, Xuan (2017-04-27)

It is a well-known that fish meal supplies will not increase as most fisheries are beyond sustainable limits. If aquaculture and shrimp production in particular is expected to expand, the industry must move away from fish ...

Assessing the Reliability of Water Test Kits for Use in Small-Scale Aquaculture

Naigaga, Shamim (2015-12-11)

Water analysis kits are useful for practical aquaculture only if they give results as accurate as those obtained by standard water analysis methods. This study used weighted Cohen’s Kappa statistic to compare management ...

Chemical composition and pollution potential of fish and shrimp feeds

Chatvijitkul, Sirirat (2015-12-04)

The objectives of this research were to assess the resources use for producing aquaculture feeds and to determine the waste loads of nutrients to the culture system (system loads), along with the solution to reduce nutrient ...

Effectiveness of coated controlled-released sulfate as an algicide for phytoplankton control in ponds

Viriyatum, Rawee (2013-04-23)

Copper sulfate and diuron are the two common treatments for controlling blue-green algae, the cause off-flavor in aquaculture ponds, especially catfish ponds. Copper sulfate has been used most widely because of its lower ...

Evaluating various management strategies of biofloc systems and understanding the physiological basis behind the thermal tolerance of Pacific white shrimp, Litopenaeus vannamei in low salinity waters

Hussain, Aya S. (2023-04-28)

Biofloc technology (BFT), in its various types, has been known to be a realistic solution for efficiently managing water quality with low or no water exchange, enhancing shrimp growth performance and establishing an efficient ...

Evaluation of Bacterial Amendments for Improving Water Quality in Alabama Catfish Ponds

Li, Yilin (2015-07-21)

Four sets of experiments were conducted to evaluate the potential efficacy of bacterial amendments for improving water quality in channel catfish ponds. First, the effects of 12 bacterial amendments from eight companies ...

Geographic Variation in Trace Element Profiles of Shrimp and Viability of Elemental Profiling as a Traceability Tool

Davis, Robert (2021-07-07)

The increased concern about the environmental consequences of shrimp culture in importing markets has led to a greater emphasis on sustainability of the products. Traceability is an important component of making claims ...

Identification of Geographic Origin of Ictalurid Catfish and Penaeid Shrimp by Elemental Profiling

Li, Li (2012-07-18)

Three investigations were performed related to identification of geographic origin of aquatic products by elemental profiling and multivariate statistics. In the first study, fillets of channel catfish Ictalurus punctatus ...

Integrating Effluent from Recirculating Aquaculture Systems with Greenhouse Cucumber and Tomato Production

Pickens, Jeremy (2015-07-28)

Experiments were conducted to evaluate the feasibility of greenhouse vine crop production using aquaculture effluent as a water and nutrient source. In the summer of 2012, cucumbers grown with aquaculture effluent (AE) ...

Investigation of Several Factors Affecting Total Alkalinity Concentration and Its Measurement

Somridhivej, Benjaporn (2015-12-04)

The optimal endpoint pH for total alkalinity titrations decreased from 5.0 at 10 mg/L alkalinity to 4.2 for 300 mg/L alkalinity or more. The appropriate color changes for bromocresol green-methyl red (BG-MR) and methyl ...

Investigations of Ammonia Nitrogen in Aquaculture：the Methodology, Concentrations, Removal, and Pond Fertilization

Zhou, Li (2015-07-29)

Four investigations were performed related to ammonia nitrogen in aquaculture. The first investigation compared the precision and accuracy of (1) Nessler, (2) phenate, (3) salicylate, and (4) ammonia electrode procedures ...

Mobile Phone Use in Ugandan Aquaculture: Farmer Experinces and Aspirations

Matuha, Moureen (2015-07-27)

Aquaculture, being largely non-traditional in Uganda, is challenged by inadequate information and technical assistance to guide farmers. Farmers in Uganda have accumulated enough experience in growing crops and livestock ...

Phosphorus and nitrogen budget for inland, saline water shrimp ponds in Alabama

Sun, Wei (2012-11-08)

Phosphorus and nitrogen budgets were prepared for ponds in an inland low-salinity shrimp farm in the Blackland Prairie region of Alabama. The study was conducted during the first crop in three ponds which were newly ...

Potential Influence of Climate Variations, Water Quality and Soil Quality on Uganda’s Aquaculture

Naigaga, Shamim (2018-09-28)

Fisheries production from lakes and other natural waters in Uganda is declining, and expansion of the aquaculture sector is needed to increase aquatic protein for human consumption. The present study was conducted to improve ...

Towards a better understanding of host-associated genetic markers for identification of fecal pollution sources in environmental waters

Ren, Wenjing (2023-09-06) ETD File Embargoed

Fecal contamination of surface water is a major public health concern and threatens ecosystem health. The water quality of many waterways in the United States has been declining due to pollution from both point and nonpoint ...
