live in the same cages as salmon where they attack and eat parasitic sea lice. Only small numbers of farmed wrasse have so far been deployed in salmon farms, with the majority coming from the wild.
Sea lice attracted by chemical signals from salmon, study finds. New international research led by Norway's Nofima sheds ...
Many copepod species have independently adapted to a parasitic way of life using a wide range of animals as hosts. How patterns of new host use develop in copepods is largely unknown. We are studying ...
Breathe easy, though—in reality, Cymothoa exigua, the parasitic isopod in question, only targets fish. Commonly known as the tongue-eating louse, it measures only about 0.3-1.1 inches in length ...
