Hmm, okay. I was looking at converting oz to lbs. That would've eliminated 2 sides of the fish, but apparently my estimates are off. That's what you get for math mostly in your head.
Will have to rework this and see where I goofed. I used a rounded 2,000 lbs as a ton too as it was an even number. That's probably part of it too as I am over rounding/simplifying.
