This article carries out a systematic literature review of the technologies and methods applied in aquaculture rearing processes. It is intended to demonstrate that there are many opportunities for improvement in this sector, given that many of the aquaculture practices are still carried out in a rudimentary way. A review of related articles of techniques applied in aquaculture in different databases was made. Within different categories, the obtaining of beneficial results was evidenced due to the use of innovative technologies or methods. Some of the main results were: reduction in feed cost of up to 21%, increase in the size and weight of aquaculture species of up to 15% and 23% respectively, and energy savings of up to 58%, which demonstrates the obtaining benefits after the implementation of modern procedures.
