Strict harvest restrictions designed to protect the bay's crab population have pushed the ratio of females to males, also known as Jimmies, to nearly 3-to-1, said Tuck Hines of the Smithsonian Environmental Research Center. Hines, who plans to study how that may affect the population, was one of a number of scientists who spoke Tuesday in Edgewater at a seminar hosted by the center to announce funding for bay fisheries research.

Maryland and Virginia imposed harvest restrictions in 2008 that focused on protecting female crabs and the once-dwindling population has since rebounded, although females now greatly outnumber males.

"So, there are not very many males around and those males are mating repeatedly," Hines said.

Females mate only once and then can produce six to 10 broods in lifetime, typically four to five in the Chesapeake Bay, while males mate with multiple partners. However, it's not clear how the population is affected when the number of partners increases for male crabs, Hines said.
