Nutritional Data at a Glance- Seafood

February 5, 2021

All nutritional data can be found on the United States Department of Agriculture FoodData Search site!

Below you will find data on some of the nutrients available, per 100g, in commonly fed seafood.  For macronutrients (carbs, calories, protein, fat, including energy in kcal, water, fiber & sugar) see the USDA's site (fatty acids are also detailed on their website). 

**µg = microgram**

**for some listings, you may see I included the Vitamin D nutritional info 2x; the 1st line with "IU" is the international measurement (which is sometimes on the label of some supplements), directly below that you may see Vitamin D again, but with "µg" which is just the measurements in micrograms!**

When following a strict BARF or PMR diet, some of the nutrients most commonly lacking are: 
Vitamin E
Vitamin D

If present in any of the seafood shown below (no matter how little), I have gone ahead and highlighted them for you! 


- Wondering which fish are typically safe to feed in a raw diet?
Using the diagram above, it is recommended to feed fish displayed on the upper right hand side of the chart (biomagnification is real y'all). 

- Be careful when considering cod liver oil in a diet that already includes liver (like beef liver for example) because it is very high in Vitamin A! Triple check your math if you're going to be including CLO alongside other secreting organs. 
And remember Vitamin A (Retinol) is a fat-soluble vitamin, meaning excess can be stored in the body, therefore in adult dogs, it can be balanced over time. But you want to be mindful of the amount being fed because you should not be constantly feeding excess amounts well over the recommended allowance.

- All fresh fish must be frozen for a minimum of 3 weeks before raw feedings. 
If you're in the United States and you purchase your raw fish already frozen, from a grocery store (fish meant for human consumption), you typically do not need to freeze for an additional 3 weeks. 

- DO NOT feed cooked fish with bones still intact!

- Remember to ALWAYS cook/steam mussels, oysters, shellfish (like crab or shrimp...), even squid & octopus (though they, along with shellfish like shrimp & crab, are not actually necessary in a raw diet).
The above mentioned foods should always be cooked prior to feeding, in order to avoid the risk of toxoplasma gondii infection
If you're in the United States and purchasing seafood from your local grocery stores (meant for human consumption), frozen mussels sold on the half shell or without the shell are OFTEN already lightly steamed. This would be safe to feed as is. To be sure, the package should indicate this. If you are ever unsure whether or not a package of mussels has been pre-cooked, you can always cook them before serving/meal prepping!
The same can be said of oysters canned in water. Most often, they have already been steamed and if this is the case, they would be safe to feed right away!

- If fresh fish is not available, feeding those canned in WATER with no added salt, oil or other seasoning, could be a great alternative. 
Just remember to look up the nutritional data for the specific brand & type of canned fish being fed, as the data will be completely different from what I have shared below!

- When it comes to feeding raw salmon, it is often recommended to avoid salmon from the Pacific Northwest (including those sourced from Alaska) because they can carry a parasite that causes salmon poisoning. Though it is not extremely common and many people have consumed & fed salmon from the PNW with zero issues, it is still significant enough for you to be aware of, before choosing to feed raw salmon to your pets. 
If the salmon is cooked, then there is no need to worry about where it is sourced from, as exposure to high heat (ie. cooking the fish), would eliminate the risk of the parasite causing salmon poisoning.

- None of the fish I feed/have access to contain thiaminase, but if you want to learn a bit more about thiamine & thiaminase, I already have a post detailing everything you need to know!
