Abstract: In recent decades, salmon consumption in the world has tripled and Brazil playing an important role in this consumption. The production of wild salmonids has been suffering a decline according to Mordor Intelligence (2024), in 2020 only about 550,000 tons of wild salmonids were caught, while more than 2.6 million tons of farmed salmonids were produced, which represents approximately 74% of the total salmon production in the world. Given the importance of this activity, this article aimed to point out the main environmental impacts of salmonid production in nurseries, as well as its economic importance. The research was carried out using the Google Scholar platform as a source of research data, having as inclusion criterion the relationship between salmon and aquaculture. The optimal for the production of salmolids should be in waters with temperatures preferably between 5oC and 10oC during the period of life in the sea, but in fresh waters the temperature should be and between 10°C and 16°C. Farmed salmon offers reduced costs and constant availability, however it also has environmental impacts that need to be carefully managed in order to mitigate the negative impacts on natural aquatic ecosystems. Among these environmental impacts, we can mention the pollution of the waters with residues and chemicals used in fish farming and the risks of crossing farmed salmon with wild populations, which can lead to alteration of natural genetics and potentially weakening the resistance of wild species. As for the economy, this market was estimated at US$ 33.5 billion in 2024, and is expected to reach US$ 49.39 billion by 2029. Therefore, it is clear that there is a need for strategies to mitigate the negative effects of this sector in order to preserve marine resources for future generations.
