Female blue crabs getting tagged in Gulf migration study

blue crab tagged1024x1024Their scientific name – Callinectes sapidus – means “beautiful swimmer.” But just where, when and how far do blue crabs – specifically, the Gulf of Mexico’s adult female blue crabs – beautifully swim? A just-started, Gulf Coast-wide research project involving affixing tags on as many as 30,000 adult female blue crabs aims to try answering those questions. Insights garnered through reporting of the recovery of those marked crustaceans should help fisheries scientists better understand the population dynamics of this key coastal marine species and translate that knowledge into sound, science-based management decisions. Those management decisions will be crucial to maintaining a healthy population of blue crabs, the Gulf Coast’s most abundant large crab – a vital prey/predator component of the marine ecosystem and an economically and socially important piece of the recreational and commercial fishery. There is a lot to learn about blue crabs. Read the rest here 22:45

To save their depleted species, female blue crabs go the extra mile to spawn in the bay

Deep under the cold, dark waters of the Chesapeake Bay, the answer to whether the decimated blue crab population can survive lies buried in mud. Tens of millions of female crabs are scattered across the floor of the lower bay in southern Virginia, where the estuary pours into the Atlantic Ocean, waiting out winter for one of the most important events in their short lives. When spring comes, they will inch closer to the ocean with billions of eggs. Read the rest here 11:21
