Female Blue Crab Population Up In Chesapeake Bay, Juvenile Numbers Low
Chesapeake Bay blue crab population appears to have a healthy number of spawning-age female crabs, according to the 2020 Blue Crab Winter Dredge Survey. Maryland, Virginia and the Potomac River Fisheries Commission aims to conserve more than 70 million adult female crabs annually to ensure enough young crabs can be produced to sustain the population, a task that has now been achieved for the sixth consecutive year. This year’s survey estimates 141 million adult female crabs were conserved, which is above the long-term average of 126 million. The total amount of blue crab in the Chesapeake Bay in 2020 was 405 million crabs,,, >click to read< 14:56
Blue crab population declines by almost 18%
The annual Blue Crab Advisory Report by the Chesapeake Bay Program and developed by the Chesapeake Bay Stock Assessment Committee, finds that the overall Chesapeake Bay blue crab population decreased by almost 18 percent from 455 million in 2017 to 372 million in 2018. The report, released last month, provides scientific analysis of the Bay’s blue crab population to help resource managers as they set blue crab fishing regulations.,, According to the report and the scientific reference points that resource managers follow for “target” (healthy) and “threshold” (border between safe and unsafe) levels, the Bay’s blue crab population is currently not depleted, nor is it being overfished. >click to read<20:12
Lost Crab Pots: Not as Bad as We Thought?
Back in 2016, a team of scientists from the Virginia Institute of Marine Science said watermen lost an astounding number—145,000 crab pots, leading to the deaths of millions of dollars’ worth of crabs trapped in those pots. But a different panel of scientists says it’s not as bad as they originally thought. Glenn Davis, who chairs the Chesapeake Bay Stock Assessment Committee, told a winter meeting of fisheries managers that the VIMS numbers are wrong.,,, But once the VIMS study was out there, it was hard to take back. And sure enough, somebody tried to monetize it.>click to read<09:05
A Good News Report: Blue crab numbers rebounding
Blue crab population numbers have grown for the second straight year, especially for female crabs, but their numbers are still below target levels, a Chesapeake Bay Program report released Thursday said. The report also found that crabs were not being overfished, with about 50 million pounds taken last year over 2014’s 35.2 million pounds — the lowest harvest in 25 years. It urged regulators to stay the course and maintain crab management regulations in order to maintain the progress. Female crabs rebounded from a depleted 68 million in 2014 to 194 million at the beginning of the 2016 crabbing season, and juvenile crabs, those that will grow to harvestable size by the fall and grow into large crabs by next season, were also holding steady.

Scientists unable to completely explain the mystery of the missing blue crabs
A year and a half ago, there seemed to be no shortage of good news about blue crabs. The annual winter dredge survey estimated 764 million blue crabs were in the Bay, the most in 19 years and a huge jump from the previous year. The governors of Maryland and Virginia issued a joint news release talking about the “extraordinary explosion in juvenile blue crab abundance.” [email protected] 13:19
