A new water sensor that has been designed to measure a range of water quality and fish welfare parameters in aquaculture installations has been launched by a Canadian seafood tech company, Sedna Technologies. The wireless Sensor Globe is a powerful multi-functional sensor concept, which can be equipped with various high-end micro-sensors and used to monitor real time data through an app on a smartphone, tablet or via the internet.

It has adjustable internal ballast so that it can either float like a small iceberg, sink or have neutral buoyancy. It measures only 95mm diameter, weighs 325 grams and is designed to “flow-with-the-fish” through pipes, hoses, fish pumps, lice treatment and other machinery. Measuring both water quality and physical impact on the fish (acceleration and shock), which both are crucial for fish welfare.

“We are now launching the first version which is available with micro-sensors such as optical oxygen, temperature, pH, acceleration and shock. Later this year nitrate, ammonia and salinity micro-sensors will follow, and we will keep adding many new sensors and features going forward to stay leading edge,” said Sedna’s co-founders, Sheamus MacDonald and Aleksandr Stabenow. Sedna Technologies Norway AS in Stavanger will be the hub for commercializing the product throughout Europe, Asia and Africa.The product is in reality a disruptive technology and with a price point that opens up a huge global market”.
