Fish are not silent creatures. Just like the terrestrial world, theres a veritable symphony of sound echoing under the sea.

Due to nitrate accumulation during nitrification and low water-exchange rates in recirculating aquaculture systems (RAS), nitrate levels can build up. Hendrik Monsees has therefore investigated the effect that exposose to high nitrate concentration has on juve…
