What you need to know about wild-caught vs. farm-raised fish

What is farmed fish?  Is one source more sustainable than the other?  Does wild-caught fish mean that it’s healthier ?

We know the benefits of eating fish and now that we know that overfishing is an issue. You might wonder about sustainability and many people seem to be unsure of the differences between wild-caught and farm-raised fish.

Many people actually assume that wild-caught fish must be a lot better for you because it’s more “natural.”

Short Answer: It depends!  There are a lot of factors to consider such as nutrition, sustainability, safety and cost. And the outcome will be different depending on the species of fish, as well as where and how the fish is caught.

Wild-caught: caught by fisherman in their natural environment.

Farm-raised: grown in pens that are often submerged in ponds, lakes and salt water

Sustainability 

It can be a misconception that farmed-fish are more sustainable because they have been promoted by the fishing industry and governments as the solution to declining fish stocks in our ocean. However, fish-farming practices often causes a lot of pollution throughout the water and threaten existing creatures and habitats.

However, traditional fishing isn’t the solution either. Wild fish are harvested in a way that does a lot of collateral damage to the ecosystem and other fish. When fishing boats are sent out into the ocean, this isn’t very carbon-footprint friendly. Additionally, destructive fishing methods such as Super Trawlers are extremely harmful to our oceans.

Health

Besides protein, fish are also the main source of omega-3 and low in saturated fats. The nutritional benefits between the two are not as great as you imagine.

For some species, such as the rainbow trout are almost identical in terms of calories, protein, and most nutrients.

  • Omega 3: In terms of vitamin 3, farmed fish have significantly higher levels.
  • Contaminants: From a widely cited study , they found that the levels of PCBs,  a potentially carcinogenic chemical, to be ten times higher in farmed fish than in wild-caught fish. However later studies  found that these levels are similar between the two.
  • Mercury: Levels in mercury are higher in some species of wild-caught fish such as the Bluefin Tuna.

Sustainable Sushi 101

Every time you enter a sushi restaurant, simple ask: “Do You Serve Sustainable Seafood?”

Yes we agree, ‘sushi is love, sushi is life’ but have you ever thought about how your choice of sushi actually impacts the environment?  Now that we know some of the detrimental effects of overfishing, it’s important to re-think some of our everyday actions, such as seafood choices, in order to save the fish. 

Sustainable sushi is made from farmed or fished sources that can be maintained for future generations without jeopardising ecosystems. Unsustainable sushi can lead to concerns for the environment, economy and health.

Choosing sustainable sushi is one of the ways to stop overfishing, this choice can lead to the emergence of more sustainable sushi restaurants, responsible fisheries and stricter government regulations.

Better Sushi choices include: 

These species are generally resilient to fishing pressure and are caught/farmed using techniques that have low environmental impacts. Some of these species may still have minor conservation concerns, but have been assessed to be a better seafood choice.

Sushi to avoid: 

Wild caught species in this group, whether Australian or imported, may be overfished or their capture heavily threatens our oceans.
