As part of an overall feasibility study, we will undertake a quantitative and qualitative appraisal of all potential source waters for each potential site. On-site measurement of dissolved oxygen, pH, and temperature will be performed for all potential water sources at high potential sites. A certified US lab will perform a chemical analysis of major and minor elements plus heavy metals for all submitted samples of potential water sources. Depending on the location and land usage patterns found in a particular area, we may recommend a pesticide/herbicide/fungicide screening of the prospective source waters. Water quality results will be compared against optimum criteria for fish farming. A quantitative analysis of seasonally adjusted potential flow rates will also be performed.
Our water quality analysis service is also available to existing aquaculture operations. Let our team water quality experts, led by Dr. Claude Boyd, troubleshoot your water quality issues.
Soil Quality Analysis
Soil quality is important to the prospective farmer that seeks to build a more traditional semi-intensive fish or shrimp farm utilizing earthen ponds. This type of operation relies upon the proper composition of local soils to form stable and watertight earthen ponds. Where land-based aquaculture is concerned, earthen ponds are considered the most cost-effective way to retain water for fish and shrimp farming operations.
Comprehensive soil horizon analysis at multiple sampling locations within each potential site are performed as part of our overall aquaculture feasibility studies whenever soils may be suitable for earthen pond construction. Soil pH testing is done on-site for all boreholes and at multiple soil sampling horizons. General on-site observations on soil type are also be made. A certified United States lab will perform a comprehensive soil texture analysis and soil chemical analysis of all major and minor soil nutrients for multiple samples taken from the most suitable sites. We will then review soil quality test results against optimum criteria for aquaculture.
Soil texture classification is determined by the percentage of sand, silt, and clay in a given sample. From these percentages, soils are then classified by type according to the soil triangle. Soils suitable for earthen pond construction must contain a minimum of 20-30% clay and preferably no more than 30% sand. The best types of soil for aquaculture are classified as clay, silty clay, silty clay loam, and clay loam.
