Zoo staff and other scientists collaborate to bring the cucumber smelling smelt back to tidal Thames

摘要

Smelt are small, predatory fish that were once very common, but whose numbers have declined significantly since the early 19th century, disappearing from many UK rivers. The fish has been recognised as a priority for conservation, and ZSL (Zoological Society of London) is helping to conserve the smelt in the Tidal Thames which has a small, but nationally significant population.
