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.
As of today in the UK (as an example)
Beef: 9.11 GBP / kg (at ~ 23g protein/100g raw beef) is 3.96 GBP /100g protein.
Tofu: 1.80 GBP/ 450g (at ~ 16g protein/100g tofu) is 2.50 GBP /100 protein.
So how exactly is meat cheaper?
