land veggies to nourish marine fish

[Charles Silva]

Hello
Can marine fish digest land veggies ("salad") like green cabbage, romaine lettuce...?
I haven't finding any article proving the benefit of using green land veggies for marine herbivore and even the comercial brands they don't include those fiber rich veggies in their recipe.
What are the benefits of offering land veggies ?
The fact of a fish eat a romaine lettuce is equal to digest ? or it only serves like a candy ?

thanks
