Important Note: If anyone in your picture is under 18 years of age, we must have a photo release signed by a parent/guardian before we can post your picture. By sending any photos or art to the Maryland Department of Natural Resources you are giving DNR permission to use the image(s) online and in print. You are also giving DNR permission to distribute the photo for non-commercial purposes to other media, print, digital and television for their use. You are not giving up your copyright, but are allowing the photo(s) to be used for educational and news purposes. All Photos will be made available on Fisheries Service Flickr Page.

There will be random drawings throughout the year from angler's participating in any of the Volunteer Angler Surveys. We encourage anglers to continue to report snakehead catches through the Inland Freshwater survey in addition to their Angler's Log submission. The information helps our biologists better understand the various species and water systems they utilize.

Maryland Fishing Challenge Logo showing striped bassA new component of the Maryland Fishing Challenge includes invasive species reports submitted to the Angler's Log. Beginning during the 2013/2014 tournament, Angler's Log entries which include Blue Catfish, Northern Snakehead or Flathead Catfish, at any length in size, will be eligible for up to two prizes via a random drawing at the annual Maryland Fishing Challenge Finale. Fish must be kept and a photo showing the kept fish is mandatory. Multiple entries are allowed, but each fish can only be entered once. Remember, all invasive species must be dead to be entered and there is no catch and release category. Visit the Maryland fishing Challenge web site to read the complete set of rules.

Parasitic Worms in Yellow Perch

Type: Tidal
Region: Bay Wide

Q: I had a great day catching some yellow perch after a long day of work. Brought four keepers home. A buddy mentioned something about yellow perch having worms in their meat. Is there truth to this? And if so, are they harmful for consumption? Can they be cooked out? Thanks, any insight is appreciated.

A: I don't know about current conditions, but yellow perch and just about any other species of fish are susceptible to parasitic worms. Usually called "black spot or white spot" disease in fish, the worms are one stage in the life cycle of a parasite group known as digenetic trematodes. This group goes through a complex life cycle involving an invertebrate, a fish and an aquatic bird as hosts. The stage found in fish can be numerous at times and give a an unpleasant appearance. However, they do not pose a risk to humans. We do recommend that anglers avoid eating fish with any lesions. However, some anglers carve out the "spots" or worms from the fillet if there are not too many.

Inquiry on Parasitic Worm in Yellow Perch

Type: Tidal
Location: Tidal and Nontidal Waters

Mike Hohm recently sent in the picture below of some strange red worms he found in a yellow perch he was cleaning. The red worms in the picture are called Philometra worms that are a common parasitic nematode worm in fish. A small larval stage of the worm is released into the water by infected fish and this small larval stage is eaten by tiny copepods (a small invertebrate) which act as an intermediate host. The copepods are then eaten by fish and the larval stage of the worm is released into the digestive system of the fish. Once in the fish the larvae migrate to target organs and molt into adults where they can become encysted in the viscera (guts) or muscle of the fish. They may grow as long as 2 in length and often move out of the cysts when the fish is dead and can be found free in the body cavity or flesh when the fish is being cleaned by a fisherman. The life cycle of these worms is not well documented but they are a common parasite in freshwater and estuarine fish such as striped bass, perch and other species such as minnows. They can not infect humans and as with all parasites cooking kills them.
