Eating fish is good for you and your child because it is a good source of many vitamins and minerals, as well as omega-3 essential fatty acids. 

But you should avoid eating some types of fish and limit the amount you eat from others.

fish to avoid during pregnancy:

If you are pregnant or trying to become pregnant, do not eat:

  1. shark.
  2. Swordfish.
  3. Marlin.
  4. These species of fish contain a high mercury content, which can affect the development of the child's nervous system.  

fish to avoid during pregnancy: (fish to be limited):

Tuna:

If you are pregnant or trying to get pregnant, you should limit the amount of tuna you eat, as it also contains high levels of mercury.

Do not eat more than:

2 tuna fillets per week (each weighing about 140 g if cooked or 170 g if raw).
4 medium cans of tuna per week (about 140 g per can if drained).

Types of oily fish:

Pregnant women should also limit the amount of oily fish they eat, as it contains contaminants such as dioxins and polychlorinated biphenyls (PCBs).

Do not eat more than 2 servings of oily fish per week.

It is not necessary to completely abstain from eating oily fish, as the health benefits outweigh the risks until you eat more than the maximum recommended amount.

Oily fish species include:

  1. Salmon.
  2. Trout.
  3. Herring.
  4. Sardines.
  5. Mackerel.

You should also limit the amount you eat from some other fish that are not considered oily.

Do not eat more than 2 servings per week of:


  1. Dogfish (rocky salmon).
  2. Under.
  3. Sea bream.
  4. Turbot.
  5. Halibut.
  6. Crab.
  7. Studies have shown that these may have similar levels of contaminants to oily fish.

Fish to limited during lactation

During lactation:

  1. Do not eat more than 1 portion of shark, swordfish or marlin per week (this advice is the same for all adults).
  2. Do not eat more than 2 servings per week of oily fish.
  3. There is no need to limit the amount of tuna you eat while breastfeeding.

Types of fish that do not need to be limited during pregnancy and lactation:

Fish is a good source of protein and contains many vitamins and minerals, as well as omega-3 essential fatty acids.

Adults are advised to eat at least 2 servings of fish per week as part of a healthy and balanced diet, of which at least 1 should be oily fish.

The same applies to pregnant women who are trying to get pregnant or breastfeeding.

It is not necessary to limit or avoid other species of white and non-oily fish, such as:

  1. cod.
  2. haddock.
  3. hake.
