Aquaculture

AQUACULTURE IN TODAY'S WORLD

The emerging aquaculture industry is one of the fastest growing food source industries worldwide. As consumers demand higher quality food products, producers and distributors are looking for sustainable technologies to meet those demands. Aquaculture farmers face many challenges including an increasingly competitive global marketplace, strict environmental regulations, rising energy and production costs. Farmers must always be on the lookout for newer, more efficient and cost effective technologies to allow them to meet those challenges while maintaining profitability.

CWSI's patent-pending Add-o-mizer technology can assist in promoting both clean water and suitable oxygenation of the water in various aquaculture environmnents including tanks, ponds and tidal basins, while reducing energy costs. In addition, this technology can be used to clean the water in tanks or ponds, without the use of chemicals, once the fish have reached maturity and have been harvested. Moreover, the concern related to biological contamination from the waste products from the aquaculture and uneaten food can be addressed and remedied with use of this technology.

Another feature of our Add-o-mizer technology is significant energy savings. Traditional oxygenation technologies typically use large horsepower pumps to move the water for aeration. CWSI's technology utilizes high-pressure, low horsepower pumps to move the same volume of water through our system. Our technology can achieve sustained dissolved oxygen (DO) levels far superior to traditional methods using a fraction of the energy required in traditional systems. Energy reductions can be substantial.

The Add-o-mizer is an oxygenator that produces a water to sustain the aquaculture in a way that efficiently utilizes the food they are eating, thereby attaining marketable weight of the aquaculture in a shorter time, using less feed. Traditional methods for diffusing oxygen into water presents a challenge in preventing oxygen bubbles from escaping the water into the atmosphere. The Add-o-mizer technology has addressed and remedied these occurrences, thereby creating an oxygen-rich aquaculture environment allowing for increased metabolism while reducing the biological contaminants in the water.

TIDAL BASINS

Tidal basin aeration presents a unique set of challenges, including maintaining sufficient oxygen levels in the fish cages. Typically, the fish cages are highly concentrated with fish, thus substantial quantities of oxygen are consumed in the cage creating a need to supply oxygen to the water within the cage. This problem is compounded in tidal water due to the movement of the tide back and forth across the fish cage, making it difficult to supply adequate oxygen to the confines of the cage. Even if oxygen is dispersed in the cage, the tide moving through the cage tends to sweep the oxygen from the cage.

CWSI's "O₂ at Sea" system utilizes the Add-o-mizer technology for dispersing oxygen into a submerged fish cage in tidal water. The tidal movement of the water is taken into account while oxygen, or air containing oxygen, is strategically dispersed in the fish cage such that the tidal movement of water through the fish cage tends to efficiently distribute the oxygen for use by fish within the cage. The system is provided with an oxygen injector control system that controls the delivery of oxygen to the fish cage with relation to the tidal flow.
