Fish is tasty and healthy, but many species are overfished and in danger of extinction. How do we persuade people to choose the right fish in the right moment?

In persuasive services, David Kjelkerud has created a mobile service just for that. Sending “fisk” + specie to a number you get a sms back with the status (green, yellow or red) and extra information. The service is still in beta version but functional in www.fisk.cc
