You can't breed cattle successfully on pasture at stocking densities of 3 cows per acre. The thin cows just won't all get pregnant and have successful pregnancies.

Fat, happy animals have lots of offspring.

Ok fair point. If your facts are correct. Certainly fisheries can become so plentiful that culling is important to keep stocks healthy.
