These may be go-to choices for a lot of us seafood lovers, but you're actually doing more harm than good by consuming these types of seafood. While eating certain types of seafood are endangering species, others indirectly affect the balance of the entire ecosystem. So in light of the Sustainable Seafood Festival on June 8, be a little more conscious about your next menu decision.

Bluefin tuna

Farmed or wild-caught Bluefin tuna is severely overfished. They also contain a lot of mercury, which is quite harmful to our bodies in the long run.

 Shark

An estimated 80 per cent of shark species that are caught are endangered. It doesn't help that only their fins are cut off and bodies are discarded into the water for a slow and painful death.

Chilean seabass 

Only choose it if it has an MSC-certified label, or if it comes from South Georgia in the UK, Australia or New Zealand. This is because the species is usually caught by longline fishing, which drastically impacts the seabed's ecosystem.

Flower crab

The uncontrolled fishing methods used by small fisheries in the South China Sea are causing the population to deplete rapidly. Perhaps give the soft-shelled crab a miss next time.

Tiger prawns 

To make way for tiger prawn farms in Indonesia and Thailand, mangrove forests are cleared, which in turn affects other species.
