I've seen old (as late as the 1930s, maybe) photos of fertilizer companies drying fish for processing.

If you check out the ingredients on some plant food, it may list fish.

I don't think you understand. I don't have a problem with the fish as fertilizer. I have a problem with the TOXIN IN THE FISH making it's way into the food supply.

I had that thought as I hit "Post".

I was going to throw in a disclaiming along the lines of "Red Tide"
breaking down. After all, it does "go away" after a while.

I had never thought about it affecting fish, since I used to occasionally
harvest mussels while on vacation, and was cognizant of the blooms.
