Atlantic Shrimpers Ltd. was established in Lagos, Nigeria in 1996 and has grown into a successful global business. In 1996 the shrimp fishing fleet consisted of 16 vessels and currently, there are 72 vessels actively fishing for shrimp. In 2016 ASL opened a 160-hectare black tiger shrimp farm in Badagry just outside Lagos. This facility includes its own hatchery and processing plant, to be able to control the quality of the final product through its entire cycle. The total production capacity is 1,200 tons per annum. The farm including the hatchery and processing plant provides work to approximately 300-350 local people.
Atlantic Shrimpers Inc. has chosen to use UV as they are dealing with a large volume of water. In combination with large drum filters, it’s possible to disinfect large quantities of water continuously. The method that was used to disinfect previously was chlorination, but besides the fact that this method is more expensive, it also works in batches, reducing the availability of renewal water for the farm. Another reason to choose UV is that it’s relatively low maintenance and works continuously. As Atlantic Shrimpers Inc. is operating in Africa we don’t want a complicated and labor-intensive process. The last reason is that UV is relatively harmless unless you look directly into the lamp. Another option would be to ozonate the water, but this can create dangerous scenarios when using high dosages.
When operating a shrimp farm, there is a long list of potential shrimp diseases to deal with. The most common one being the White Spot Syndrome Virus (WSSV). It was imminent that a biosecurity update was required and the use of UV in combination with drum filters was the chosen solution. The channel systems are used for treating large volumes of water that are used as renewal water for the shrimp ponds. The closed vessel UV is used specifically at the hatchery as the requirements for hatchery water are even more stringent. All 4 delivered UV disinfection systems are made from polypropylene material, making them the perfect solution for saltwater resistance in warmer climates.

“One of the reasons we chose ULTRAAQUA UV is because we had a pleasant conversation at AquaNor in Trondheim. They are easy to reach in case of questions and the prices were competitive. The required level of biosecurity determines the need for a certain lamp output and ULTRAAQUA UV has done a great job in assisting with this by showing literature that explains the needed dosage to kill a certain disease vector.”
