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.

Instructions for including new fishing sites:

  1. Make sure you have your coordinates in decimal degrees. For example, latitude: -0.4429, longitude: -76.51793. If they are still in geographic coordinates (degrees, minutes, and seconds), please convert them to decimal degrees. Between four and five decimal places is considered ideal precision.
  2. Each site must have a unique name, following the nomenclature name of the site-area or main basin-name of the water body. For example: Iquitos-Amazon Basin-Nanay River.
  3. If it is a market or port, specify in the name. For example: “Iquitos: Mercado de Belén”.
  4. Put the name and coordinates of the new fishing site on this spreadsheet (VProximo Sites Update sheet). Make sure you fill in columns A, B and C.
  5. If you want to remove sites, use columns F and G. If you want to change coordinates (move a site), use columns I-M). If you want to change the name of a site, use the O-S columns.
