Can you keep carp and trout in the same lake?

No, you should not keep trout and carp in the same lake. Carp are highly adaptable and can tolerate a wide range of environmental conditions, including low dissolved oxygen levels. They can also reproduce quickly, which can overpopulate the lake and compete with trout for food and habitat. Trout, on the other hand, are more sensitive to water quality and require a higher oxygen content to survive. They can also be territorial and may become stressed if they have to compete with carp for food and space.
