RD428 - The 2015 Virginia Blue Crab Fishery Management Plan
Executive Summary: Results from the 26th Bay-wide Winter Dredge Survey, conducted from December 2014 to March 2015 (Attachment I) by the Virginia Institute of Marine Science and Maryland Department of Natural Resources, indicate the blue crab stock is not depleted and overfishing is not occurring. The 2014-2015 Winter Dredge Survey estimates of abundance of all size classes of crabs was 411 million crabs, and this total abundance represents a 38% increase from the 2013-2014 Bay-wide Winter Dredge Survey but is below the long-term (1989-90 – present) average of 454 million crabs. The most recent abundance of juvenile crabs enumerated from this winter survey was 269 million, and is slightly greater than the long-term survey average of 261 million juvenile crabs. The importance of the juvenile crab surveyed in wintertime is its contribution to the following late summer and fall harvest when it has recruited to harvestable size and its contribution to the subsequent year’s May and July-August spawning periods. The number of overwintering female crabs that could potentially spawn (if not harvested prior to the spawning seasons) in 2015 was 101 million. This was an improvement over the 2013-2014 survey estimate of 68.5 million which was considered a depleted spawning stock. However, 101 million potential spawners is below the long-term average of 115 million potential female spawners. The importance of the mature female crabs is their contribution to the spawning events in late May and July – August of the same year the Baywide Winter Dredge Survey is completed. These crabs also are important to the spring and early summer harvest, as a high proportion of the Virginia commercial and recreational harvests consist of female crabs. |
