I'm a vegetarian who generally doesn't eat fish, and my motivations include not being super comfortable with being complicit in animal suffering and slaughter. (Also some environmental concerns, as well as the diet just being a pretty good fit to me.)
One exception is that I sometimes take fish oil tablets. Now my f.o.tab-habits are pretty fickle because of my mixed feelings about the matter. Maybe they'd be great for me, but I don't take them regularly enough to know. Maybe a single fish can be made into many pills. Maybe thousands of fish are "concentrated" into a pill. Maybe the oil is somehow derived from fish that are also eaten, making it somewhat less of a moral cost, though still not perfect.
So my basic question is how many fish, and perhaps also how many pounds of fish (are these big or little ones) does it take to make one of these pills. Also are lots of collateral damage fish or other sea animals getting killed in the process of netting the ones needed for the pills?
Bonus points for comments on the level of suffering in modern fishing. Is it mostly nets pulled out of the water (i.e., drowing in the air) like I would guess?
Here's the fish oil I have
in my medicine cabinet right now.
