Yellow Grub
The yellow grub is a large (3 to 8 mm or 1/8 to 1/4
inch), common parasite in North America (Olsen
1962). Yellow grubs are embedded intermuscularly (in
the muscle) or subcutaneously (under the skin) in fish.
The most common fish-hosts in North America are
yellow perch, bass, and sunfish (Olsen 1962);
however, it is a relatively safe to assume that the
yellow grub is capable of infecting all freshwater fish
species because it has been reported from many fish
species (Hoffman 1999). When present, the parasites
are highly visible to the unaided eye after skinning or
filleting because of their size and color. The yellow
grub is not harmful to humans if removed or cooked;
however, anglers and consumers do not readily accept
infected fish because of their unsightly appearance
(Hoffman 1999). Elliot and Russert (1949) have
reported individual yellow grubs living in fish for
about 4 years
YELLOW, BLACK OR white cysts or "grubs" are often found in fish and frogs. The sunfish family, which includes bluegill, largemouth bass, and green sunfish are all susceptible to infestation by this worm. These fish are sometimes known as perch, brim or goggle eye. Channel catfish are also susceptible to grub infestations that can render this commercial species unmarketable.
Grubs are most often found in or at the base of fins and just below the skin between muscle segments. However, they can be found in almost any part of the fishes body. Yellow grubs range in size from as small as a pin head to as large as a pea. Black grubs are small and resemble black pepper sprinkled on fins or flesh of fish. Grubs are not harmful to humans. Eating fish containing grubs will not cause sickness or parasitic infection. However, most people find it objectionable.
