On 4th of march 2018 a seminar presented under the title History of Fish Health by Asst. Prof. Dr. Samir J. Bilal.
Fish is a word we may hear every day and we imagine that is so clear word and has so clear meanings, but what we not know are fishes just like any fish we see in markets or aquariums? No, there are different fish groups, for example, some fishes have lungs and can breathe O2 like man.
The presentation aimed to clarify the different groups of fishes (including living groups and Fossils) on our planet, especially fishes are the larger group of vertebrates now present on earth.
