Severinsen re-emerges with a disruptive water sensor

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.

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.
