Fish migration

The removal of migration barriers (such as dams, hydroelectric power stations, pumping stations, locks, etc.), as well as the restoration of habitats, has been identified by water managers as an important measure to achieve healthy fish stocks.

Fish migration

Did you know that; The earliest known fish passages come from local people who helped fish to pass obstructions in French rivers in the 17th century. Branches were bundled which were placed in such a way that fish could defy these barriers. The first patent of a fish passage dates from 1837 and was therefore a French invention.

In the past, it was also known that for healthy fish stocks, it is important that the fish species present should be able to reach a sufficient number of suitable habitats at every stage of life and in every season. In addition, it is important that there is sufficient exchange of genetic material between populations.

A good exchange between populations ensures genetic diversity within the populations, giving them greater resistance to diseases and reducing the occurrence of abnormalities. Research has shown that fish are of vital importance to the human ecosystem.

That is why fish stocks are one of the biological quality parameters within the European Water Framework Directive (WFD). The WFD asks water managers to derive the objectives and measures for fish stocks.

The overcoming of barriers

The removal of migration barriers (such as dams, hydroelectric power stations, pumping stations, locks, etc.), as well as the restoration of habitats, has been identified by water managers as an important measure to achieve healthy fish stocks.

Climate change, rising sea levels, glacier disappearance and subsidence mean that our water managers have to protect us more and more against the coming water. As a result, more and more barriers are created in naturally free fish migration routes. It is best to remove a barrier or obstacle, but in most cases it must be maintained for artificial water and water level management.

The variety of species has decreased enormously and there are already fish species threatened with extinction, which is why people around the world are working on solving the fish migration bottlenecks. Large-scale research has shown that fish passages can be improved and from the point of view of water management, Vislift has received the request to develop the fish passage of the 21th century.

That is why Vislift has developed a fish passage with ecologists and water managers to make fish migration easier, cheaper and much more efficient for all stakeholders. The Smart Fish Lift: a technological fish passage.

Data fish migration

Fish migration, data and research; One of the possibilities with the implemented artificial intelligence, the Smart Fish Lift measures all the main fish migration values, and fish are monitored. Water quality measurements are also carried out, which are related to the migrating fish. Through continuous term measurements we get much more science and data from fish migration, ecology, water quality and sedimentation. Thanks to its artificial intelligence, the Smart Fish Lift will eventually anticipate this and alert the manager in good time in order to improve and monitor the eco and water system.

When several Smart Fish Lifts are placed in a water system, a lot of monitoring data can be collected that can be converted by Vislift into usable standardized and standardized water system values. This enables Vislift to provide the relevant water manager with its mandatory periodic inspection and monitoring reports, which are set within the framework of the Water Framework Directive.

This creates valuable data and science that can be retrieved and used in an area-specific and specific manner. The measurements and grid of the Smart Fish Lifts allow us to learn almost everything about our water world and to use this data for all kinds of purposes. In this way, the water manager can save on research costs. The Smart Fish Lift makes the water world smart and digital.
