What Fish is High in Mercury ?

Mercury levels differ from one species of fish to the next. This is due to factors such as the type of fish, size, location, habitat, diet and age. Fish that are predatory (eat other fish) are large and at the top of the food chain, and so tend to contain more mercury.


Fish that contain higher levels of mercury include


- Shark                     - Barramundi

- Ray                         - Southern Blue-fin Tuna

- Swordfish              - Yellow- fin Tuna

- Gemfish                 - Rockling

- Orange roughy

Mollusc Benefits 

Mussels, oysters and scallops are some of the most nutritious foods known to man. Low in calories, they are an excellent source of protein, vitamins and Omega-3 oils that help reduce the risk of heart disease and protect against certain forms of cancer.

Shellfish also contain life-enhancing minerals like copper, iodine, iron, selenium and zinc, which is critical to human libido and male fertility.



Our Mussels 


As one of the cheapest forms of fresh seafood available, you really can't go wrong with mussels. They are high in protein, low in fat and contain lots of healthy omega 3 fatty acids. 

Australian blue mussels (Mytilus galioprovinicalus) are the most popular kind in the world because of their sweet and tender nature. Female meat is orange in colour while males have white or cream flesh.

Portarlington mussels are sustainably farmed - mussel farming is a relatively benign form of aquaculture as mussels don't require active feeding by farmers - they filter phytoplankton from the water, keeping it clean and benefiting the environment. The clean waters of Port Phillip Bay are monitored fortnightly for bacteria and algae to ensure the quality of the mussels.

The mussels are grown on ropes suspended in deep water (hence there's no sand in the shells). The ropes are hoisted up and run through special machines that strip the mussels, which are then cleaned and graded, sorted and boxed on the boat before being sent to their processing plant.

Seafood and Pregnancy 


Unborn babies are at increased risk from mercury. The mercury in fish can lead to raised mercury levels in the mother. This mercury can be passed on through the placenta to her developing baby. 

The fetus appears to be most sensitive to the effects of mercury during the third and fourth months of a pregnancy. The effects on the brain and nervous system may not be noticed until developmental milestones - such as walking and talking - are delayed. Memory, language and attention span may also be affected. 


What's safe to eat?


Eat a variety of seafood that's low in mercury and high in omega-3 fatty acids, such as:


  • Salmon

  • Anchovies

  • Herring

  • Sardines

  • Trout

  • Atlantic and Pacific mackerel


Scallops are low in calories and packed with quality protein, making them a good food to enjoy for weight loss or if you are at risk of cardiovascular disease or type 2 diabetes. Scallops also contain selenium, a mineral with antioxidant properties that can help manage arthritis and maintain healthy skin, and magnesium, a mineral that may aid in blood-pressure control.
