3 fish you should avoid eating

Our ocean is now in a state of global crisis, brought about by overfishing. 85% of fishing grounds around the world are already overfished. Hence it is important that we make the right choice when choosing seafood. Some choices can affect the survival of species, the health of the ocean and people’s livelihood.

Here are three species of fish we should avoid consuming, and why.

1. Shark

Sharks are important in the marine ecosystem. As top predators, they help to regulate prey populations. When removed, they affect the balance of the ecosystem.

Unfortunately, one quarter of the world’s sharks and rays are threatened with extinction due to overfishing, habitat loss and ocean pollution. Here’s more:

In case you’ve heard of sustainable shark’s fin, here’s why there is no such thing as sustainable shark’s fin.

2. Stingray


Most stingrays are considered to be from unsustainable, overfished and poorly managed fisheries. Perhaps we should reconsider our choice the next time we crave for barbecued sambal stingray?

3. Tuna (especially blue fin tuna)


Tuna is one of the world’s most widely consumed species of fish, deemed as a seafood delicacy in many cultures. To keep up with this global demand, supply chains are known to use fishing techniques which unfortunately result in overfishing and/or indiscriminate fishing.

Tuna sashimi is a very popular Japanese delicacy around the world.

Tunas are an integral part of the marine food chain. They are among the top predators in the ocean, in particular the Bluefin Tuna which comprises of the Southern, Atlantic and Pacific Bluefin. Overfishing has caused all three species of Bluefin Tuna to be vulnerable to extinction, resulting in an imbalance of the marine eco system.
