Juvenile abundance is largely driven by environmental factors, such as currents, temperature, and winds, therefore year-to-year variability is expected.Īlthough juvenile abundance this year is below the long-term average of 254 million, it remains an improvement from the 2018 recruitment and well above the low of 105 million reported in 1992. ![]() The number of juvenile crabs declined in 2020 to 185 million, from last year’s total of 323 million. The total abundance of blue crab in the Chesapeake Bay in 2020 was 405 million crabs, a near-average abundance for the 30 years of survey results. This year’s survey estimates 141 million adult female crabs were conserved, which is above the long-term average of 126 million.Īdditionally, the results showed there were 79 million adult male crabs, just above the long-term average of 77 million and similar to the estimate from 2019. Maryland, Virginia, and the Potomac River Fisheries Commission strive to conserve more than 70 million adult female crabs annually to ensure enough young crabs can be produced to sustain the population, which has now been achieved for the sixth consecutive year. The 2020 results showed that the Chesapeake Bay blue crab population maintains a healthy number of spawning-age female crabs.
