Now, increased demand for traditional fishmeal – which is made from small species caught in the open ocean – has sent the industry scrambling for alternatives.
The stuff being used to make fish feed is a byproduct of the poultry industry – it’s what is left over after the parts of the chicken consumed by humans and the remains used for cat and dog food have been removed.
Seriously it’s in the body of text in the post. Leftovers of the chickens that cannt be used for humans dogs and cats get used for the fish.
This is like people arguing against leather at this point when millions of animals are being slaughtered and their hides are being thrown into landfills because demand is so low. If they are already slaughtering the animals, use the parts. As demand for cows/chickens comes down find alternatives, but throwing away parts of a slaughtered animal is worse to me.
