The research involved patents deposited/provided between 1999 and 2019, with the search in the system occurring through the descriptors: fi sh(s), mollusk(s), crustacean(s), and algae(s). A total of 363 records were found, where the group of fi sh presented the highest representation (40%), followed by algae (35%), crustaceans (14%), and mollusks (10%). The apex of 34 patent applications was found in the year 2011. Moreover, the results showed that the inventions registered are directed mainly to food, drugs, biocides, cosmetics, cultivation, processing and benefi ciation, water treatment, patents for sustainable technologies (green patents), and biotechnology. Brazil holds most patent applications, followed by the United States of America (USA), which focuses its patent applications mainly on algae and fi sh. Considering the Brazilian biodiversity and the country's technological development in recent years, Brazil needs to expand its technological autonomy and competitive capacity in the aquaculture and fi sheries sector, mainly through the strengthening of R&D and innovation activities.
