Study identifies how zebrafish regrow their brains

(Medical Xpress)—An international team of scientists has discovered the mechanism by which zebrafish can re-grow brain neurons after they have suffered traumatic brain injury, and that this mechanism is associated with ...

A 'social' gene in fish could contain new clues to autism

Zebrafish are social creatures. When they see another member of their species, they'll orient towards them and swim closer, much like a human at a cocktail party turning to face someone who's telling a joke over a plate of ...

A newly discovered circuit helps fish to prioritize

Being constantly flooded by a mass of stimuli, it is impossible for us to react to all of them. The same holds true for a little fish. Which stimuli should it pay attention to and which not? Scientists at the Max Planck Institute ...

What social distancing does to a brain

Have you recently wondered how social-distancing and self-isolation may be affecting your brain? An international research team led by Erin Schuman from the Max Planck Institute for Brain Research discovered a brain molecule ...

Fish

Tetrapods

A fish is any aquatic vertebrate animal that is typically ectothermic (or cold-blooded), covered with scales, and equipped with two sets of paired fins and several unpaired fins. Fish are abundant in the sea and in fresh water, with species being known from mountain streams (e.g., char and gudgeon) as well as in the deepest depths of the ocean (e.g., gulpers and anglerfish).

Food prepared from fish is also called fish, and it is an important food source for humans. They are harvested either from wild fisheries (see fishing) or farmed in much the same way as cattle or chickens (see aquaculture). They are also exploited by recreational fishers and fishkeepers, and are exhibited in public aquaria. Fish have had a role in many cultures through the ages, ranging from deities and religious symbols to the subjects of books and popular movies.
