Fish are also seasick

A German scientist insists that fish are also seasick as humans and some animals.

Doctor of zoology Reinhold Hilbig (living in Stutgart, Germany) explores the effects of domestic weightlessness. This is part of the study of the effects people face in space. He dropped 49 fish into a small water tank and put it on the plane. When the plane dives to the bottom, it will create the same weightless condition as in flights into space.

Hilbig found 8 fish swimming in a circle for a long time in the experiment. 'The fish flood completely loses the sense of balance and orientation. They move like people with seasickness and seem to want to vomit food out , ' Hilbig said.

He conducted brain scans of 8 seasick fish to find out why they lost their sense of balance and orientation. 'When the plane dives, the movement of the water is chaotic and the fish cannot observe around. It seems that the situation, along with the shaking of the water, is the main reason why fish lose their sense of direction and balance, ' Hilbig said.
