No pic so can't see what you are referring to as "blackspot" but I am guessing small round black dots on the skin? Never seen it on a trout before, only on perch, northern pike and rock bass. If it is true blackspot it is completely harmless to humans but it's probably best to remove the skin to consume the fish. It is a parasite that only develops into a worm if the fish is consumed by a bird I am told by a biologist friend I shoot skeet with. It is also mostly prevalent in warmer waters and warm water fish species. Funny I have seen lots of the above mentioned species with it and yet walleye, whitefish, herring, burbot, black crappie, sunfish, largemouth and smallmouth bass and musky from the same waters not a single one with it?
