Pages : 688
Book Description
Commercially the Pismo clam (Tivela stultorum)ranks first in importance in California among the clams and third among all the mollusks, being exceeded only by the oyster and the abalone. A second reason for considering this species is that there has been such evidence of depletion as to lead to increasingly more stringent protective laws, all of which have been urged by the residents of the county in which the clam is most abundant. ... An accurate study of the cause and extent of this apparent diminution must await knowledge of at least the fundamental facts of the life history of this clam. ... The more important features are considered to be: the habits, enemies and mortality of the adult; the rate of growth and the factors affecting it; the age at certain significant periods, particularly at sexual maturity and at the time when the legal size is reached; the most common age of clams forming the commercial catch; the season of spawning and the productivity; and the habits, enemies and mortality of the young.

Book Description
In this lively history and celebration of the Pacific razor clam, David Berger shares with us his love affair with the glossy, gold-colored Siliqua patula and gets into the nitty-gritty of how to dig, clean, and cook them using his favorite recipes. In the course of his investigation, Berger brings to light the long history of razor clamming as a subsistence, commercial, and recreational activity, and shows the ways it has helped shape both the identity and the psyche of the Pacific Northwest. Towing his wife along to the Long Beach razor clam festival, Berger quizzes local experts on the pressing question: tube or gun? He illuminates the science behind the perplexing rules and restrictions that seek to keep the razor clam population healthy and the biomechanics that make these delicious bivalves so challenging to catch. And he joyfully takes part in the sometimes freezing cold pursuit that nonetheless attracts tens of thousands of participants each year for an iconic “beach-to-table” experience.
