23.02.2021 – report confirms functionality according to German standards

A new commissioned report confirms our both pilot plants a “good functionality”, which is the best grade for fish ladders in Germany. For the evaluation the leaflet “Merkblatt DWA M 509“ and the guideline “Methodenstandards BWK (2006)” were used. The evaluation was performed from an independent office.

If you have any question to the evaluation or you are interested in the report, don’t hesitate to contact us!

05.01.2021 – more than a million barriers in Europe’s rivers

In December 2020 the Nature magazine published a very interesting article about a Europe-wide study on barriers in our rivers. Because of around 1.2 million constructions there is in average a barrier every 1.4 km in rivers. Around a third is higher than 2 m. If it is not possible to remove the barriers, our FISHCON-lock can restore the water continuum in a very sustainable way! We look forward to contribute with our technology and enable an environment- and climate-friendly future!

09.12.2020 – online presentation about the FISHCON-lock

Due to the Corona-situation multiple presentation at conferences from FISHCON had to be cancelled. Nevertheless, we could present our FISHCON-lock interested parties at several online-events. One presentation from the CEO Bernhard Mayrhofer, which was made for the swiss organisation “Wasser Agenda 21”, you can find under the following link in German or also translated in French:

Enjoy the presentation! If you have any questions, don’t hesitate to contact the team of FISHCON!

26.08.2020 – The second pilot plant is functional as well!

At our second pilot plant in the river Aschacharm more than 5.000 fishes from over 27 species used the FISHCON-lock for their upstream migration. Among them some fish swarms and weak swimming species. The biggest fish was an eel with around 70 cm. But also, migrations of a pike with around 60 cm and a zander with around 61 cm could be determined. The FISHCON-lock was designed for a fish with a length of 60 cm.

Because of these good results, a positive evaluation according to the Austrian regulation was possible.

 We are satisfied with the results and file at the moment first projects in Austria and Germany. If you are interested in our technology or the results, don’t hesitate to contact us!


15.07.2020 - Big chance for Austrian public contractors!

A few months ago, FISHCON received the certification “IÖB-tauglich”. With this certification FISHCON and its innovative FISHCON-lock is presented on the IÖB-innovation platform ->

This helps FISHCON to attract attention at the public sector, it also allows public contractors and sectoral contractors from Austria to get a grant up to 100 % by using the FISHCON-lock for restoring the water continuum ->

09.06.2020 – development of the turbine moves forward

In end of May the prototype of the turbine was tested at the FISHCON-lock Alm. We could carry out measurements for determining the turbine efficiency and tested the automated concept for grid connection with success. 

We look forward for the first FISHCON-locks with turbines!

24.03.2020 – first fish migrations in spring 2020!

At the pilot plat Aschacharm first fish migrations could be observed before the official start of the monitoring, among others many nases and a pike with a length of 60 cm. This is the length of the main fish, which was basis for designing the FISHCON-Lock at this river.

A few selected fish migrations form March 2020 are shown in the video on the right side. Further videos from the FISHCON-Lock are presented on our YouTube-Channel.

14.01.2020 – The development of the turbine is


Over the Christmas holydays a fist turbine prototype was successfully tested. The efficiency goals could be even exceeded despite of the double-sided flow! Thank you very much to the Technical University Graz for the cooperation in the from Land Upper Austria supported easy2reserach project.

With the turbine an efficient and economical use of the leading waterflow as well of the residual flow for energy provision is possible. So, the technology can contribute to water conservation and climate protection in parallel.

30.12.2019 – Monitoring at the pilot plant Alm is completed - Grade 1.0!!!

fishes in the fishlock

The monitoring at the pilot plant Alm has been completed in autumn and the results evaluated a few days ago. Despite bad fish population at the spot, 683 upstream-migrations and 305 downstream-migrations over the 2-Chamber-Organismbypass from FISHCON could be documented. All present fish species used the innovative fish lock.


Due to the very positive result, the pilot plant has been evaluated as fully functional with the grad 1.0 according to Austrian guidelines!!! For further information don’t hesitate to contact the team of FISHCON!


We wish you a happy New Year and look forward for 2020!

fish lock autumn monitoring

20.11.2019 – over 500 fishes used the FISHCON-lock Aschacharm

The four weeks monitoring in autumn at the river Aschacharm is finished. We could determine an upstream migration of 18 different species, included some ground orientated fishes like gudgeons. In total 532 fishes used the fish lock in the investigation period. Because of the big range of species and the high number of fish migrations we expect even better results in the spawning season in spring 2020.


Thanks to the company Blattfisch for realising the monitoring!

17.08.2019 – Second FISHCON-lock is in operation!

In July the construction of the second pilot plant at the Aschacharm could be finished. Meanwhile the fish lock is running since weeks without troubles. We look forward for the fish monitoring in autumn.

02.06.2019 – First results of the fish-monitoring are encouraging!

The first fish-monitoring results from the pilot plant at the river Alm this spring are promising. It was possible the prove fish migration form all present fish types and the number of migrations is good as well! In the next days we start the construction of the second pilot plant in a Barbel region in order to examine the functionality in this fish region as well.

7.05.2018 – short update

We have a good feedback for our first pilot site and we are preparing a new research project in order to optimize, further develop and examine the 2-chamber-organismbypass under real conditions. At the moment, we are also extending the patent protection and we are negotiating with potential partner companies.

So, there is a lot to do and we look forward to build the first plant soon!

4.02.2018 – FSHCON is checking first possible sites for pilot pants

The interest is big! In the last weeks we could visit over 10 installation spots for pilot plants. Though not all sites are suitable for pilot plants, analyses show that the technology is almost always an advantageous solution in comparison to considered alternatives. Therefore we expect to find suitable sites in the next months and can build our first plants this year. By interest we can check your site too!

24.12.2017 – FISHCON wishes merry Christmas and a Happy New Year

20.10.2017 – FISHCON is looking for pilot plant sites!

The research project from the University of Natural Resources and Life Sciences Vienna is soon completed. Due to the promising results, it is planned to build the first two pilot plants in 2018. Therefore we are looking for installation sites, where the realization is simple and with low costs possible (heads I the beginning from 2 – 4 m).


FISHCON will support the realization! Use your chance!!!
