Which fish species was the first to be aquacultured?

The common carp is recognized as the first fish species to be aquacultured, with evidence of its domestication and cultivation in China dating back to around 2500 years ago. This long history illustrates the carp's suitability for aquaculture due to its adaptability to various environmental conditions, dietary flexibility, and ability to thrive in different aquatic settings.

Additionally, the common carp has been significant in various cultures not only as a food source but also in ornamental practices such as koi breeding. Its extensive use in early aquaculture practices laid the foundation for the development of modern aquaculture techniques and the cultivation of other species.

In contrast, while tilapia and hybrid bass are also popular in aquaculture, they were cultivated later and do not have the same historical significance as the common carp. Shrimp is a farmed species but falls under crustaceans rather than fish, thus making it a different category in aquaculture distinct from the focus on fish species.
