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.

Excerpt from The Life-History and Growth of the Pismo Clam, Vol. 7: Tivela Stultorum Mawe On the coast of California are found six or eight species of mollusks which are commercially important. Of these, the amounts marketed are shown in the following table, and to this considerable total must be added those used locally, regarding which no data are available, although the number, in some localities, is known to be large. These animals thus represent a valuable economic asset and there is good reason to believe that their importance can be materially increased. Yet of their life histories - the rate of growth, the age reached, the age of spawning, the productivity and many related problems - we know next to nothing. The introduced soft-shell (Mya) and the eastern oyster have been studied on the Atlantic coast; the native oyster is being investigated (Scofield, 1921: Stafford, 1913, 1918), but for the other native species there exists no body of known facts and only a few scattered observations. While making a survey of the edible bivalves of the State (Weymouth, 1921) this lack was so strikingly apparent that it was thought profitable to work out the life history of at least one important and representative species. The species chosen was the Pismo clam (Tivela stultorum). Commercially the Pismo clam ranks first in importance in California among the clams and third among all the mollusks, being exceeded only by the oyster and the abalone.
