Sharks, Clams, Conchs and Oysters

Sharks are managed by the National Marine Fisheries Service (NMFS) and the Atlantic States Marine Fisheries Commission, and the regulations are complex. For more detailed information contact the NMFS or visit State regulations are subject to any changes in federal regulations. Please consult for the latest changes in state regulations. See 2014 Seasons, Size & Creel Limits for more information on shark seasons, sizes, and daily limits.

Common Delaware Sharks

The sand tiger, sandbar, smooth dogfish (or smoothhound) and spiny dogfish are the most commonly caught shark species in Delaware. Sandbar and sand tiger sharks are of special significance to the Delaware Estuary and its anglers. Delaware Bay is an important “pupping area” and nursery for sand tiger sharks, and they are commonly hooked. Due to their low reproductive rate and overfishing, both species are protected and none may be retained. No hook and line fisherman may remove from the water any sandbar shark, or any other prohibited species of shark. In addition, any sandbar shark or other prohibited species of shark must be immediately released in a manner that will ensure the maximum probability of survival.

Clamming Methods of Take and Limits

A fishing license is required to harvest clams in waters of the State of Delaware. See Fishing License Requirements & FIN Number for details.

It is unlawful for any person to attempt to take, catch, kill or reduce to possession any hard clams with a device other than a hand-held rake with a head no wider than fourteen (14) inches measured perpendicular to the tines and a straight handle not in excess of seven (7) feet in length.

It is unlawful to harvest hard clams from one-half hour after sunset through one-half hour before sunrise.

It is unlawful for any resident to harvest more than one hundred (100) clams per day unless otherwise permitted to do so by license or permit.

It is unlawful for any non-resident to harvest more than fifty (50) hard clams per day unless otherwise permitted to do so by license or permit.

No shellfish harvesting (excluding crabs) is allowed in the Prohibited Areas marked on the map on Fishing & Clamming Maps or any tidal river, stream, or impoundment of the state. This includes all non-tidal and impounded water as well. Shellfish harvesting is allowed from December 1 through April 15 in the Seasonally Approved Areas. This is your protection against contracting shellfish-borne diseases. This is also the law. All boundaries may be marked with signs and or buoys saying “No Shellfish Harvesting” or “Prohibited Shellfish Area”. Questions regarding these closures should be directed to the Watershed Assessment Section Shellfish and Recreational Waters Programs 302-739-9939. Clamming is prohibited in eel grass beds marked with white PVC pipes and signs.

Minimum Hard Clam Size

The minimum size for a hard clam is 1 1/2 inches from point A to point B.


1 1/2 INCHES



It is unlawful to recreationally harvest oysters in Delaware. This prohibition protects vulnerable oyster populations and protects you against contracting a shellfish-borne disease.


Conch (channeled and knobbed whelk) may only be taken using conch pots with at least one escape vent measuring at least 5 inches x 10 inches in the top or parlor section. The recreational harvest of conch by any other method is prohibited. Recreational conch potters may not use, place, set or tend more than two conch pots. The person claiming to own the pots must be the one to set and tend them. These pots must be marked with all white buoys with the owner’s full name and permanent mailing address inscribed either on the buoy or on a waterproof tag attached to the buoy. All conch pots must be tended at least once every 72 hours. Conch must measure at least 6 inches along the axis or have a minimum diameter at the whorl of 3.5 (3 1⁄2) inches for knobbed whelk or 3.125 (3 1⁄8) inches for channeled whelk.
