Did you know that frog tadpoles can be captured using electrofishing?

Electrofishing is one of the common methods used to sample fish stocks in freshwater environments. Electrofishing can also be used to move fish out of way when, for example, rivers have to be diverted. This is called ‘fish translocation’ and differs from ‘fish salvage’.  Translocation is undertaken before a river is diverted or enclosed and has a higher efficiency.

Electrofishing is also useful however for sampling amphibians such as frogs and newts, and during our electrofishing surveys and translocation work we often encounter frogs in particular. In the photo below we were undertaking brook lamprey translocation work at a stream that was about to be diverted to facilitate construction works. However, we were also able to catch common frog Rana temporaria tadpoles. These were also collected and safely moved out of the way of the works.

ECOFACT staff are expert in aquatic ecological and fisheries consultancy work. We provide a wide range of fisheries surveys and fisheries consultancy services, and are experts in the translocation of fish, lampreys and amphibians from construction areas.
