Choosing the right type of fish can make a big difference to your health, the environment, and even your culinary experience. Two of the most common types of fish available in markets and restaurants are wild caught fish and farm fresh fish. But what’s the difference? Are both types of fish healthy? Which one is better for sustainability? In this blog, we’ll break down the differences between wild caught fish and farm fresh fish, highlighting their unique qualities so you can make an informed decision the next time you head out to buy fresh fish.
What is Wild Caught Fish?
Wild caught fish refers to fish that are caught in their natural environment, typically in oceans, rivers, or lakes. This fish is harvested using various fishing methods, such as trawling or fishing with nets. Wild caught fish are often considered to be more flavourful due to their diet of natural foods, like smaller fish, plankton, and algae.
What is Farm Fresh Fish?
Farm fresh fish is raised in controlled environments like fish farms or aquaculture facilities. These farms are designed to replicate natural habitats, though the fish are usually fed a specific diet that differs from what they would consume in the wild. The most common farmed fish include salmon, trout, and tilapia.
Comparing the Wild Caught Fish vs Farm Fresh Fish: Key Differences
1. Nutrition
The nutritional content of fish depends on what they eat. Wild salmon get their omega-3 fatty acids from plankton, smaller fish, and other seafood. Their pink and orange colour comes from crustaceans like krill. On the other hand, farmed salmon, raised in pens, are fed pellets made from fish meal, fish oil, plant proteins (such as corn and soy), animal proteins, vitamins, minerals, and carotenoid pigments to give their flesh an orange hue.
According to Sanna Delmonico, MS, RDN, CHE, due to differences in diet and their activity levels, which make wild fish leaner, Atlantic farmed salmon contains twice as much total fat as wild Atlantic salmon (13.5 grams per 100g, compared to 6.5g per 100g). It also has significantly more omega-6 fatty acids and three times as much saturated fat. However, farmed fish can sometimes have higher levels of omega-3 fatty acids than wild fish.
2. Contaminants
One of the biggest concerns with wild caught fish is the potential exposure to environmental contaminants. Wild fish can accumulate mercury and other toxins found in the oceans, which can pose health risks when consumed in large quantities. However, certain wild fish, such as those caught in clean, well-regulated areas, tend to have lower levels of these contaminants.
Farmed fish are usually raised in more controlled conditions, which can reduce the risk of exposure to contaminants. However, some fish farms use antibiotics and other chemicals to control disease, which can raise concerns. It’s important to look for sustainably farmed fish, as these are less likely to be exposed to harmful substances.
3. Sustainability
Sustainability is another key difference between wild caught and farm fresh fish. Overfishing is a significant issue with wild caught fish, as many fish populations have been depleted over the years due to unsustainable fishing practices. Choosing wild caught fish from sustainable sources, such as those certified by organisations like the Marine Stewardship Council (MSC) or Aquaculture Stewardship Council (ASC) can help mitigate this issue. You can identify sustainable products by the MSC blue label. Examples of MSC blue label products include Seaco’s Haddock Loin, Salmon Portion, Cod Loin, Alaska Pollock Fillet,
Farmed fish, however, is often seen as a more sustainable choice, as fish farms can produce large quantities of fish without depleting wild fish populations. Yet, fish farming itself poses environmental challenges, such as water pollution and the use of wild-caught fish as feed. Therefore, selecting fish from responsibly managed farms is key to ensuring sustainability.
4. Taste and Texture
Taste and texture are subjective, but many people believe wild caught fish has a more pronounced flavour and firmer texture. This is because of their natural diet and active lifestyle. Farm fresh fish, being raised in more controlled environments, may have a milder taste and softer texture due to their diet and lifestyle.
How to Choose Fresh Fish Fillet
Regardless of whether you opt for wild caught fish or farm fresh fish, it’s important to know how to select the freshest fillets. Look for fish with firm, moist flesh that doesn’t appear dry or slimy. The colour should be vibrant and the smell should be fresh, not overly fishy. If you’re buying fillets, ensure the flesh is free of dark spots or discolouration.
When buying fresh fish, it’s always a good idea to check the source. Opt for fish from reputable suppliers who prioritise quality and sustainability. In some cases, farm fresh fish can be a better choice due to the higher degree of control over quality.
