The ichthyology is a discipline that within the zoology deals exclusively with the fish study. Not only will it be in charge of describing and providing fundamental data on the various species that exist and the new ones that are appearing, but it will also delve into issues such as the behavior and biology of fish.
Fish are aquatic animals that since the beginning of the world have stood out as a result of the nutritional contribution that they knew how to contribute to man in his diet.
When man discovered this issue, he obviously dedicated himself to protecting them to ensure their consumption.
In those initiation times of humanity, fish were used especially to be consumed in various foods, while over time their use added new variants such as sport fishing and its breeding, as is done with livestock. in general, for later commercialization.
Then, it follows from the aforementioned that fish are animals that have enormous relevance in people's lives as well as in the balance of the ecosystems of which they are part.
In its formal history, ichthyology has described a phenomenal number of fish species, more than thirty thousand, however, they never cease to bring us news and there are many unknown species that suddenly and after some study come to light and they add to the list.
Now, as a consequence of being such a complex and vast universe of study, ichthyology does not act per se but also uses other fellow sciences to act, such is the case of the Marine biology that studies the species that inhabit the seas and oceans, or the oceanography which deals with addressing all the phenomena and processes that occur in seas and ocean; wave limnology that deals especially with the water ecosystems that inhabit the continental part of the planet.
