All were carefully inspected during good tides (W. It is found in the nearshore subtidal areas in gravel or boulder beaches and live clams are frequently washed ashore on the sandy beaches during large storms.ĭistribution and use-The following localities in Northern California contain beds large and well stocked enough to warrant more than casual digging. Along the coast it occasionally located in beach areas among boulders with mixed gravel and coarse sand associated with headlands and the rocky shore. in accumulated gravel and sand among the rocks in exposed situations. It burrows to a depth of from three to eight inches though occasionally it is found at the surface. It is usually located nearer the entrances of the bays but higher in the tidal zone in saltwater dominated bay, such as Humboldt Bay and Tomales Bay. It is found in much the same areas as the Martha Washington clam and cockles in areas with a substrate composed of firm mud, mixed sand and mud and in mixed gravel with sandy mud and in gravel and rocks mixed with sandy mud. ![]() Littleneck clams are also common to the gravel and cobble substrate associated with rock headlands along the California coast. The presence of the clam is confirmed by inserting a bamboo stick into the show but the clam is often located to one side of the show and is easily missed. The show of littleneck clams is often confused with shows of other clams. #CLAM TO HORSE CLAM TO GEO DUCK PLUS#A ¼ inch plus keyhole shaped show often discloses the presence of the clam 1 to 8 inches under the sand, sandy mud or combination of sand/sandy mud/gravel of the tidal flats in areas of the larger bays exposed during a minus tide. The shell is distinctly longer in proportion to its height, while the smaller Manila clam often colored bluish on one end and appears as wide as it is long. Littleneck clams seldom exceeding three inches in length. My favorite the Littleneck and Manila clams, (Venerupis staminea & Venerupis japonica) are commonly referred to as steamer clams. A resumption of that study in 2008 showed sport clamming effort has decreased to an estimated 1,300 diggers extracting a total of 31,189 clams (Brooke McVeigh, DFG, personal communication). DFG annual creel census surveys conducted from 1975 to 1989 reported annual effort and catch estimates as high as 6,639 diggers extracting 188,000 clams in 1982 (Collier 1992). The bay also supports recreationally important bivalve species, particularly in South Bay, including gaper clams, Washington clams, and littleneck clams. The rock cockle (Paphia) and the gaper (Schizothaerus). Humboldt Bay-Washington clam (Saxidomus) and the soft-shell (Mya). Double click the image of Humboldt to increase the size of the image. Usually make it home to dig clams with my dad no more than once per year. However, there are a few ocean facing beaches where razor clams can sometimes be found. ![]() Mainly I just saw them when digging on the flats for bait. Or at least that is what my dad always called them. The clams are Horsenecks and Martha Washingtons. The survey revealed an important shift in harvested clam species composition, a decrease in harvest level, and methods of harvest apparently unique to Humboldt Bay.Ĭlick on the Humboldt Bay National Wildlife Refuge for additional information about Humboldt BayĬlam digger Bruce wrote: I am from Eureka. Data were collected on clammer effort and catch resulting in bootstrapped estimates of the number of clammer trips (clammer-days) per year, catch per unit effort, total catch by species, and spatial distribution of effort within the bay. Surveys were conducted on low tides in the south arm of Humboldt Bay. ![]() Click on following link to view the CDFW information survey on digging clams in Humboldt Bay.Ī sport clam survey, conducted January through December 2008 in Humboldt Bay, California, was the continuation of a creel-type survey conducted by the California Department of Fish and Game from 1975 through 1989. ![]()
