Ictio is an application and database on Amazonian migratory fish, built through collaboration between local and indigenous people, individual fishermen, management groups, associations and scientists.

Developed by the Cornell Lab of Ornithology in collaboration with the Wildlife Conservation Society and project partners, the database and free application for mobile devices allow fish observations to be recorded and shared.

We seek to understand how fish migrations work in the Amazon Basin and what environmental factors influence these migrations.

The citizen science approach allows us to address the information gaps in Amazon preservation, drastically reduces the cost of gathering this information and empowers citizens to become guardians of aquatic ecosystems.

Ictio allows you to record:

  • Species
  • Number of individuals
  • Weight (kg) / Total weight
  • Location
  • Selling price
  • Date
  • Photographs


Users can view and share their data, as well as keep a record of the species they catch over time. With all this generated information, we will seek to further our understanding of the migration patterns of priority fish in the Amazon.

  • Ictio app: The application is available for free on Google Play for Android devices (minimum version 5.0) and does not require an Internet connection to work. Users will be able to view and share their data, as well as keep track of the species they catch over time.
  • Data upload: in addition to the Ictio app, data can be uploaded to Ictio.org using the data upload tool available on this website.
  • Access to data: a basic data set will be available quarterly online at ictio.org. Partners will have access to an extended database and observers themselves will have access to their full data. Visit Ictio.org to learn more.
