"Download this app and help preserving fish stocks for future generations"

Over 65% of fish stocks in the Mediterranean are considered to be exploited beyond safe biological limits. The overexploitation of our seas presents a serious threat to marine ecosystems and their wonderful biodiversity, endangering rare species which already struggle for survival, including marine mammals and turtles. It also puts small-scale fisheries, the fundamental part of the Greek socioeconomic fabric, at risk. Archipelagos’ research has shown over 50% decline in landings of small-scale fisheries in the eastern Aegean over the last years.

There is a growing concern for oceans and seas, as global fish stocks are predicted to collapse by 2048 if no preemptive measures are taken.

Making responsible decisions regarding what seafood you buy, you can help preserving the life in our seas for present and future generations. It is important to avoid certain types of fish if their populations are rapidly declining due to overfishing, but there are more factors that need to be considered when choosing seafood. Eating fish responsibly also means knowing where it comes from.

This guide will help you make sustainable choices when eating seafood.

The species included in this app have been categorized according to the following information:

  • Even if a species is legally fished, it does not necessarily mean that it is a sustainable choice. Following the available scientific knowledge, we have categorized species according to whether they are considered sustainable.
  • The market is often flooded by illegally caught and undersized species, so we offer a clear guide to identifying these.
  • As a result of increasing marine pollution, some species, both sustainable and not, are considered unhealthy to eat because of their toxicity. This guide will inform you which seafood should be avoided.

It's OK

The consumption of seafood which belongs to the green category is currently considered sustainable. According to recent knowledge its stocks are not overfished or declining. Choosing species in this category is considered to be responsible. Nevertheless, we must always choose sustainable sizes and proper seasons to avoid changing this status.

Population decline

If a species belongs to the yellow category, there is evidence that its consumption may not be sustainable. Populations may show signs of decline or recover from a previous decline. It is important to always choose sustainable sizes and seasons to keep fish populations healthy.


The consumption of species which belong to the red category is considered unsustainable. The species may be endangered, while its stocks can be critically low, poorly managed, and/or overfished. It may also be illegal to catch and consume this fish.

Potential health hazard

This species has been proven to bioaccumulate toxic substances above the limits safe for human consumption. It may be dangerous for human health, especially for high risk groups such as children and pregnant or breastfeeding women, therefore frequent consumption is not advised.

The app was created by researchers of Archipelagos Institute of Marine Conservation and developed by TEDx Thessaloniki in May 2012.
