Introduction
In the case of high head migration barriers, and especially where there are a series of barriers after each other, catch and transportation of fish on tank lorries has been used. The method can be used for up and down migration and has been used for eel, glass eel and salmon smolt. In Norway, this has been used to release adult salmon and sea trout above artificial and natural barriers, to ensure or increase fish production. The method relies on good catch efficiency and requires relatively large effort. It is basically very selective and requires repetitions in the long term but can still contribute to the occurrence or fish production of a species when other durable solutions are not realizable. Capture and transport can also be used as a temporary solution until a lasting solution is in place. The solution is used in special cases and is not recommended as a best practice.
Methods, tools, and devices
During planning
Planning of truck transport of fish must discover the relevant road system and parking places for loading and emptying the tank truck. In particular, a system for collecting fish and filling the truck must be planned, including a lifting or pumping system. A counting system for fish should be considered
During implementation
The implementation requires road and construction works and mechanical installations for a filling and counting station system downstream or next to a powerplant and a parking place for emptying the truck.
During operation
The maintenance is connected to the truck itself and any other pumping or monitoring systems.
