The suffering of animals is the main reason to care about animal welfare. In addition, we know that animals breed in conditions in which they can thrive provide the best financial returns. CO2 analysis is highly important for the fish welfare.
High carbon dioxide (CO2) concentrations negatively impact fish, which makes data on its tolerance especially relevant for production systems that can accumulate CO2 such as aquaculture systems. A recent study evaluates the effect of CO2 on the growth performance, welfare, and health.
The high concentration of CO2 is harmful to the fish in aquaculture waters environment. When the concentration of CO2 exceeds the safe level, the amount of oxygen that the blood hemoglobin of fish can carry is reduced significantly and respires distress can occur, even high concentrations of dissolved oxygen in the water.
Fish have a wide range of senses and a relatively large brain. They have a high learning capability and good memory and display advanced individual and social behavior. As such there is strong evidence that fish have a qualitative and conscious experience of being, and that their welfare is worth caring about.
Tunable is working to make a solution that can solve this highly important issue by easy measuring the CO2 level continuously with a low maintenance cost, high precision and cost efficiency.
