Catch IslandYour own island where the fish you caught swim
Catch Island is an aquarium you fill with photos of fish you caught yourself. Add a photo, we identify the species, and your fish swims in 3D around your island, in the sea or in freshwater. Nothing to install: it runs in your browser.

How it works
1. Add a photo
Add a photo of your catch and we suggest the species. Shoot it on a measuring board and we read the length too.
2. Watch it swim
Your fish swims around your island, in the sea or in freshwater, sized to its real length.
3. Decorate and show off
Collect shells to decorate your island, visit friends' islands and climb the rankings.
