Shellfish Identification<strong>New</strong> <strong>Hampshire</strong> is fortunate to have a rich variety of molluscan shellfish.Some of the most frequently seen are easy to identify by their shellshape <strong>and</strong> color.Shellfish illustrations: ©Hans Hillewaert CC 2.5: Mahogany Quahog, Razor clam;©Invertzoo GNU Free Documentation License: Surf Clam; ©<strong>Fish</strong>eries <strong>and</strong> Oceans Canada:Waved Whelk; ©NHFG/Victor Young: Ribbed Mussel; ©Pallbo: Blue MusselBlue MusselRibbed MusselSea ScallopOysterSurf ClamSoftshell ClamRazor ClamMahogany QuahogHorse MusselWaved WhelkStimpsons WhelkQuahog(Mercenaria mercenaria)NOTE: SHELLFISH CLOSURES MAY CHANGEMost of <strong>New</strong> <strong>Hampshire</strong>’s coastal waters (up to 3 miles offshore)are open to shellfish harvest, with the exception of surf clams <strong>and</strong>quahogs, which can be harvested for consumption within 500 feetseaward of the low tide line. In addition, several small areas alongthe coast are closed due to pollution concerns. These areas includethe outlets of Parsons Creek <strong>and</strong> Eel Pond in Rye, an unnamedcreek near Bass Beach in Rye, <strong>and</strong> Chapel Brook. All waters within750 feet of each outlet are closed to shellfish harvest. Additionally,all waters within 1,500 feet of Little River (near North HamptonState Beach) are closed to shellfish harvest. Also closed are areasaround the wastewater treatment plant outfalls at Wallis S<strong>and</strong>sState Park, the Town of Seabrook, <strong>and</strong> Star Isl<strong>and</strong> (Isles of Shoals).Other areas may close temporarily at any time. For up-todateinformation, call <strong>Fish</strong> <strong>and</strong> <strong>Game</strong>’s Clam Flat Hotline at1-800-43-CLAMS, check www.<strong>Fish</strong>NH.com (Marine Resources),<strong>and</strong> consult the information <strong>and</strong> maps on DES’s Shellfish Programwebsite: www.des.nh.gov (search “shellfish”).from April to October. If PSP toxins exceed state st<strong>and</strong>ards forconsumption, shellfish harvesting areas are closed <strong>and</strong> publicnotice given via news media <strong>and</strong> the <strong>Fish</strong> <strong>and</strong> <strong>Game</strong> website. Contact<strong>Fish</strong> <strong>and</strong> <strong>Game</strong> Marine <strong>Fish</strong>eries Division at (603) 868-1095or the Department of Environmental Services at (603) 559-1509,weekdays from 8 a.m. to 4 p.m., for updated information. Evenwhen red tide closures are not in effect, some areas may be closedto the taking of shellfish (see Shellfish Closures May Change).RED TIDERed tide is caused by the accumulation of toxins from one-celledorganisms. The toxins may be stored in the bodies of filter-feedingbivalves, such as clams, mussels <strong>and</strong> oysters, which ingest theorganisms. Humans who eat the shellfish may become afflictedwith paralytic shellfish poisoning (PSP), which can cause deaththrough respiratory paralysis. Mussel samples are tested weeklywww.<strong>Fish</strong>NH.com 23
