Suggestions for ocean sustainability

To help you choose the best fish and seafood in Portugal

Marine ecosystems currently face several threats. Although some of these threats are obvious, such as pollution, others aren’t easily noticed, namely overfishing.

Overfishing means fishing in excess of what would be desirable. Data are alarming: more than 70% of the world’s fish species are affected by overfishing.

The good news is that we can all help counteract the negative effects of this practice!

The Oceanário de Lisboa has created the SOS Ocean Booklet, so that all people living in and visiting Portugal can promote sustainable consumption by choosing the right species of fish and seafood to buy or order. The SOS Ocean Booklet indicates the fish and seafood species that can be consumed without compromising the future of the oceans.

Easy to consult, the SOS Ocean Booklet offers countless suggestions for protecting our oceans.

The SOS Ocean Booklet also includes relevant information to our health, namely lists of species low in cholesterol and species rich in omega-3 fatty acids, magnesium and potassium, as well as fish species in which heavy metals are likely to accumulate.

It is easy to know and respect minimum size limits for every fish species. It is our responsibility to help protect our oceans.

The future of our oceans depends on our choices.

Lista Eco-Atitudes

Think green when you shop
Buy local, seasonal produce whenever possible.

Avoid excessively packaged products
Opt for large packs to minimise paper and plastic waste.

Brilliant ideas
Energy-efficient lightbulbs use 80% less power than traditional lightbulbs. An energy-efficient 11W lightbulb produces the same amount of light as a traditional 60W lightbulb.

Have a shower for a good cause
Did you know that you use 30-80 litres of water every time you have a bath when you could use just 15-35 litres if you chose to have a shower?

Take shelter in the shade
Plant trees that provide shade during the summer. Deciduous trees lose their leaves seasonally, providing shade only in the summer.

The next time you go to the supermarket, take a fabric grocery bag and don’t forget to reuse plastic bags. Using 20 new plastic bags a month increases carbon emissions by about 15kg of CO2/year.

For the sake of the planet
Hand old X-ray plates and expired medicinal products to your pharmacist, so they dispose of them in a suitable manner.

Travel light
Avoid turning your car into a mobile storage unit: your car uses an extra litre of fuel per 100km for every 100kg of cargo. This represents an additional 24kg of CO2 and an additional 180 euros once you’ve travelled 15,000km.

Natural resources: use both sides
Always print on both sides of paper; print e-mails and documents only if necessary.

Start a new cycle at home
Sort and recycle paper, glass, plastic, cork, batteries and cooking oil.

Hooray for hats, gloves and sweaters!
Avoid using air conditioning/heating systems, as you’ll use less energy and help reduce CO2 emissions, in addition to saving money.
