The blue crab, Callinectes sapidus Rathbun, is the only important marketable crustacean in Chesapeake Bay. While this body of water may be regarded as a center of its numerical distribution, blue crabs in the United States range from Cape Cod south to Texas. Their economic importance is indicated by records of the Federal Government which report for the four-year period 1936-39, an annual average of over 82 million hard crabs valued at about $526,000 from Virginia and 56 million worth about $382,000 from Maryland. Soft crab catches in the two states during this period were approximately the same, amounting in …

It is a matter of common knowledge among conservationists that the blue crab supply of the Chesapeake is rapidly declining, being reduced from a level of about 17 millions in 1931 to that of about 10 million crabs in 1937. (Md. Rept. 1937). Numerous explanations have been advanced to account for this decline. One outstanding reason is the taking of such large numbers of "sponge" (berried) crabs and mated female crabs, a practice which undoubtedly reduces the potential supply of young crabs for the ensuing year.
Another menace to the survival of the blue crab lies in the way in …

What are the underlying causes of this declining trend? In facing this problem, so broad in its scope and so serious in its effect, the Virginia Fisheries Laboratory has, during the past year, effected an organization for analyzing conditions in our commercial fisheries and for disseminating facts about them and the need for their conservation.
