bingo.  just like Liver, Fish is a life-hack superfood.  and also like Liver it can taste bad, but doesn't have to.  

for fish the key is to not let it start going rancid, which causes the fishy taste.  for liver the key is to source it from young and healthy organic fed animals not from old diseased GMO fed animals ...

also with both liver and fish you will reach a point where your body will say i had enough and it will then taste revolting after that.

without fish, on other hand, it is virtually impossible to achieve proper Omega 3 to Omega 6 balance and eating fresh fish is superior to using Omega 3 supplements because those are usually made out of the lowest quality fish ... 

 I just had delivered 24 jars of Riga Gold (Latvian) Baltic sardines, and some Russian (yum!) mustard (not Ukrainian, yuck!)  ;-) 

 those smoked sardines in oil are delicious - i loved them since childhood in Kiev, and in Russian NYC neighborhoods you can just buy them at a grocery store.

however i must warn you that when fish is canned in oil the Omega 6 from the oil can dominate the Omega 3 in fish by a ratio of up to 10 to 1 depending on the type of oil used.

so i only have those smoked sardines in oil as delicacy on holidays, like candy.  for nutrition i use frozen wild caught salmon.  

for salmon i have to add oil and spices to make it not taste like cardboard but the crucial difference is i control which oil i use ( i typically use Coconut oil as it's the cheapest harmless organic oil and tastes good, but there are other good options too ).

industrial Omega-6 seed oils is the number one thing that changed in human diet as we went from being thin to being obese.  while only some of those oils are outright toxic the sheer AMOUNT of these oils in modern diet is a major issue. 

could say more but gotta run to gym ... 

 Most fish don't have strong flavor when fresh, you are correct, but can develop stronger flavors if they aren't fresh.

I think sardines (and other oily fish) taste fishy. But in a wonderful sardine fishy way.

Salmon tastes wonderful, always, just like salmon. Not the same kind of fishiness at all. I can't remember ever having salmon that didn't taste good. I would eat it every day if it didn't cost a mint.
