Husband's pee smells like fish & it's cloudy

I looked it up and it says it is most likely a UTI. But he has no other symptoms, no pain or burning..just cloudy fishy smelling urine. He has had this going on for a while and never noticed, but I did. Should he see our family dr about treating this or a urologist?

--thank you everyone & for being so nice with your replies. he's definitely going to be seen. i had just assumed that this was the result of a poor diet or something lol
