| Presentation | Technical and Economic Analysis the Impacts of Key Factors in Commercial Shrimp Culture |
Abstract
Several factors, such as temperature, water quality (dissolved oxygen, ammonia-N, etc.), genetics and feed quality, are known to affect the growth performance, survival and efficiency of feed utilization of shrimp. Despite the importance of these parameters, there has been surprisingly very little work on assessing and predicting their impact on performances of shrimp reared under commercial conditions.
Starting with work initiated at the University of Guelph, Wittaya Aqua developed models and user-friendly tools enabling the analysis and robust description of the response of the animals reared under variable environmental factors. These tools also enabled the standardization of growth and mortality of animals and development of robust indices reared under a wide variety of production conditions. These were then used to analyze and benchmark performance of 100s of commercial shrimp production lots. They are also used to forecast and/or quantify the impacts of different environmental factors (alone and combination) and benchmarked performance levels on productivity and profitability of commercial shrimp culture operations. Considerable variability in performances was observed across production lots, farms and countries.
This work highlights the potential of models and benchmarking in helping the industry move forward.
