Stress and metabolic monitoring system to improve fish production


Spanish researchers have developed a novel smart system which warns about changes on fish behaviour responding to external factors which are controllable in a fish farm. The system is a small, less invasive and harmless device that allows fish farmers to identify stressed fish and to perform selective breeding in a more efficient manner. Industrial partners dedicated to the manufacture or development of fish farming products are sought to collaborate through a patent license agreement.

Partner sought

Industrial partners dedicated to the manufacture or development of fish farming (vaccines, feed) and/or fish farms monitoring products are being sought to collaborate through a patent licence agreement.


Fish, like many other animals, behave abnormally under stressful situations. Such negative environment is reflected on fish growth, regardless of food availability. This phenomenon causes large economic losses to fish farm producers. Hence, the importance of reaching a health and welfare fish standard. The first step to achieve this desired standard is to implement tools for remote non-invasive monitoring of fish condition. Some of the solutions already available in the market are based on image analysis or acoustic telemetry. However, these systems have fish-size limitations or can only detect individuals close to the water surface. The system offers an alternative system that overcomes some of these monitoring constrains. It is a triaxial accelerometer implanted on the operculum of the fish, allowing the measurement of parameters in the three axes and recording the breathing frequency and acceleration activity. Moreover, this smart electronic system goes beyond data collection, processing the information using a powerful algorithm and providing fish farmers with a reliable stress indicator and a breeding selection tool.

Advantages and innovations

The system is a monitoring system that enables fish farmers to monitor stress indicators and ultimately optimize fish production. - Accessible price and high manoeuvrability. - Reusable module that features a rechargeable battery and an easy removal system. - Minimal invasion and low weight - does not exceed the gram. - Triaxial accelerometer provides unbiased and reliable results when measuring physical activity rather than speed. - Biometric monitoring of several individuals in the same space and in deeper locations far from the water Surface. - Future applications for other farm animals beyond the marine realm.

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
