The Short Answer

Mercury is a substance that does not easily leave living creatures, but instead accumulates. All fish absorb mercury from the environment around them. Larger fish, however, eat a whole lot of smaller fish that have absorbed mercury and thus the larger fish absorbs the mercury from those smaller fish. Also, larger fish live longer, so they have more time to absorb even more mercury than smaller fish. Also, I would imagine that mercury is detrimental to fish too.
