Insights
From an aquaculture perspective, the application of Fuel Tech's DGI® technology in shrimp farming represents a significant advancement in aquaculture practices. Traditional aeration techniques can limit production capabilities due to their inability to maintain high dissolved oxygen (DO) levels, which are critical for the health and growth of aquatic species. The DGI® system's ability to maintain DO concentrations at 150% of atmospheric saturation could revolutionize industry standards by enabling higher stocking densities and potentially improving animal health and growth rates.
Higher survival rates and growth yields, as reported, could lead to increased efficiency and profitability for shrimp farmers. This efficiency gain could transform the market dynamics by potentially lowering the cost of production and providing a competitive edge to early adopters of this technology. However, it's crucial to consider the capital and operational costs of implementing such technology and whether the benefits outweigh these expenses in the long term.
From an environmental standpoint, the use of advanced aeration technology such as DGI® in aquaculture has the potential to reduce the environmental footprint of shrimp farming operations. By optimizing oxygen levels, the technology may contribute to better water quality and reduce the need for water exchange, which is a common practice in aquaculture that can lead to environmental concerns such as effluent discharge and the spread of pathogens.
Furthermore, the increased efficiency in resource utilization (feed, energy, water) could lead to more sustainable production practices. It's imperative to analyze the long-term environmental impacts of widespread adoption of such technologies to ensure that they contribute positively to the sustainability goals of the aquaculture industry.
For investors and stakeholders in the aquaculture and aquatech sectors, the successful trial of Fuel Tech's DGI® technology could signal a new growth opportunity. As consumer demand for seafood, particularly shrimp, continues to rise, technologies that can enhance production efficiency and product quality are likely to be in high demand.
Companies that invest in and adopt these technologies may see improved market share and profitability. It's crucial for investors to monitor the adoption rate of DGI® technology and the performance of early adopters to gauge the potential market impact. Additionally, considering the competitive landscape, the presence of alternative technologies and their market penetration should also be evaluated to understand the potential for DGI® to become an industry standard.
Use of DGI® Enhanced Shrimp Production with Likely Health Improvements Results to be Presented at Aquaculture America 2024
The Company believes that this report evidences the multiple potential benefits of its DGI® technology for aquaculture applications, while validating the inherent flexibility of DGI® for a wide range of water and wastewater processes, environmental remediation, and industrial uses.
Shrimp farm technology provider Royal Caridea worked closely with Fuel Tech on a trial to determine the effects of growing Pacific whiteleg shrimp (Litopenaeus Vannamei) in a raceway system using the Company’s patented DGI® gas infusion system.
Shrimp farming is helping to meet growing consumer demand, and higher densities of the crustaceans are possible in the raceway than what occurs in the wild. The comparative trial took place in back-to-back growth cycles on a raceway with high species stocking and low-salinity water at Royal Caridea’s aquaculture farm in
In land-based raceways, a continuous stream of water must provide the required level of water quality for the crustaceans to develop, and aeration is necessary to meet the required parameters.
In the first growth cycle, traditional bubble aeration using the venturi principle was used until the oxygen demand of the water could no longer be met. This required that the shrimp be partially harvested to ensure acceptable dissolved oxygen (DO) concentrations were maintained for those remaining.
In the second growth cycle, Fuel Tech’s DGI® technology was used to provide DO concentrations at
The two, three-month trials are the subject of a new white paper from Fuel Tech, which shows how its DGI® process, originally developed for the water and wastewater treatment market, offers multiple benefits in shrimp production. Fuel Tech is pleased to report that excellent survival and growth was achieved during the DGI® trial.
A mean weight of 42g was reached per shrimp in about 100 days. The growth curves for individual shrimp showed no significant change from the trial when selective early harvesting was necessary to manage the high biomass loading.
The DGI® trial also revealed no evidence of trimethyl amine odor, oxidation, excessively fast metabolism, osmotic shock, or gas bubble disease. This suggests that maintaining DO levels above saturation in low-salinity water, without the presence of bubbles, increases the yield, while minimizing any detrimental effects of high oxygen levels.
In conclusion, the research shows that high post-larval shrimp stocking, combined with reliable DO dosing with DGI®, can dramatically increase total production compared with traditional aeration methods.
The results will be presented by John M. Boyle, PhD, Senior Director of Technology Development at Fuel Tech, at Aquaculture America on February 21, 2024 in
Bill Decker, Vice President of Water and Wastewater Treatment Technologies at Fuel Tech who will also attend Aquaculture America, commented, “We believe that the trials in collaboration with Royal Caridea show huge benefits in deploying DGI® for oxygen injection in aquaculture applications. Demand for shrimp is increasing globally and shrimp farming is an important source to help meet the growing demand and reduce overfishing of the marine environment. By deploying DGI®, producers now have an opportunity to improve stock health and yields, while achieving more efficient operations.”
DGI® uses a patented next generation, pressurized saturator for gas transfer of the oxygen solution to a slipstream of water; and an innovative nozzle delivery system to distribute oxygenated water that virtually eliminates gas loss from a targeted body of water.
The DGI® technology was tested using validation methodologies published by the American Society of Civil Engineers (ASCE) and its Environmental & Waters Research Institute (EWRI), and the results of the tests have been peer-reviewed and endorsed by industry experts. The validation testing white paper showed that DGI delivers greater than
