Simsonar UVC and Simsonar FC for monitoring migration of fish

Simsonar is an innovative international venture driven by the passion to provide customers with more information about migration of fish. Simsonar searches actively disruptive opportunities within the area of underwater imaging. The structure and operating principles of Simsonar target to maximized customer satisfaction. We concentrate on our core competences:
  1. Understanding the needs of the users of Simsonar products.
  2. Identifying the technological innovations that can change the established assumptions of underwater imaging.
  3. Utilizing the innovations to disrupt the current business logic and/or value chains.
  4. Understanding the modern global business networks to build relationships to the best performing partners.
Today Simsonar has two products. Simsonar UVC is based on ultrasound and is used with longer distances up to 70 meters. Simsonar FC is based on optical camera and is targeted for shorter distances. Typically it is used in fishways and narrow brook-like rivers. Both products utilize Simsonar software that detects movement, measures moving objects and creates reports automatically. Simsonar is developing a web based service to recognize species.

Supporting your needs

Monitor fish at any distance:
  1. show them as video stream,
  2. count them,
  3. measure them,
  4. report to the user,
  5. automatically.
Combine the latest technology in optoelectronics, ultrasound, electronics, communications and software with the key components developed by ourselves to become number one in the selected business segment.

February 2021

More projects were run with Simsonar FC and Simsonar than ever before. Performance, resolution and specfies recognition were improved and enhanced. We will launch a new web based reporting service in May 2021. If interested please contact Arto at Simsonar to get more information about the service.

January 2020

Another year with multiple projects with Simsonar FC and Simsonar UVC back. Thousands on detections and measurements done to provide our customers more data. Tunnel for FC will be modified for coming season. Longer (over 140 cm) salmons will be totally visible and measurement will be more accurate. Species detection will be improved dramatically. Looking forward to next summer!

December 2018

Simsonar participated Fish Passage 2018 conference in Albury Australia. New contacts were met and new knowledge was gathered. No worries, mate!

May - November 2018

The season was again the most succesful for far. SImsonar Fish Counter was taken in use in multiple sites. Customers were happy to find a reasonably priced counter for fish ways enabling 24/7 recording, automatic fish detection, measurement and counting. SImsonar UVC was once again improved from the presious season. Automatic detection and measurement is now more reliable. Simsonar Tunnel for optical counter optimizes distance to fish and lighting in all environments.

December 2017

The season was the most succesful for far. Simsonar was expecially happy for the four diffrent projects with the newest product SImsonar FC (Fish Counter). We believe the improved pattern recognition algorithm will make fish detection and measurement more accurate and faster.
The first two deliveries to Norway opened a new promising market. Simsonar UVC LR (Long Range) was used for projects requiring very high distances. The maximum can reach almost 100 meters in good conditions altough the realistic distance is 75 meters.

May 2017

Another season starting. The first commercial installation of Simsonar FC was done on May 11th. It is now monitoring a small brook. The first observations were surprising: a brook of fifteen meters wide and 70-80 cm deep contains underwater living more than anybody expected. During the busiest hour more than two thousands fish passed the camera for spawning.

March 2017

Simsonar UVC has been in the market place since 2012. It has been developed continuously and the latest update is the Long Range model. The viewing distance has been extended to 70 meters. The first delivery will be done in June.

February 2017

Development efforts for new Simsonar FC are almost done. First modest marketing efforts result in huge interest. We look forward to new season with two projects!

January 2016

Very busy season is over. Simsonar cameras were researching rivers from Gothenburg and Helsinki up to Utsjoki and Arjeplog. Although our customers take care of analysis more and more also Simsonar was busy in analysing the recorded material and preparing reports. Now we are just weeks away from the first monitoring projects start. Looking forward to new season with improved products!
