A net of one millimeter mesh was used to sample larval crabs in the surf. Poor catches of juvenile blue crabs by otter trawl in the first part of the 1963 study period were probably due to an unsuccessful spawn reported in 1962. Indications were that mating occurred from April through July, and during October, 1963. A successful spawn occurred in late fall of 1963, as evidenced by an increase of larvae in beach samples in November, and by the prevalence of small juvenile crabs in the bay in November and early December.en-USblue crabsUpper Laguna Madrestock assessmentTechnical Report
