Only male crabs larger than a minimumsize can be harvested, and only during a defined fishing season.In Oregon, male crabs must have a carapace width of at least6.25 in (159 mm) when measured just anterior to the 10th lateralspine. The Oregon fishing season begins on December 1 andruns through August 14, avoiding the fall period, during whichmost males molt and are in poor market condition. Without anyregulations directly limiting the number of large males that canbe taken each year, there is the possibility that nearly all malecrabs of legal size could be harvested.
Question 7) The season for Dungeness crab starts December 1st according to the 2012 article. Only male crab the size of 6.25(in) or 159(mm) minimum may be harvested during this season and the season ends August 14th. The fall months are avoided because this is when male molting season is. According to the ODFW website, the updated minimum size for harvest is 5.75(in) or 146.05(mm). The updated open season dates start December 1st and end October 15th. In order to go crabbing you must be 12 years or older and have a shellfish license. When catching the crab you must release any female crab immediately and any male crab must be measured. When measuring you want to use a crab gauge and you measure across their back horizontally, not including their spike on each side. When determining sex, on the underside of the male crab you will see a long skinny triangle and on female it will be more wide and round. over the past years, not much has changed regulation-wise, only a slight change in size and dates. For commercial crabbing the regulations have stayed the same since 2012, minimum size being 6.25(in) or 159(mm) and the season starting December 1st and ending August 14th. Although if you are commercial crabbing, you must have a commercial crabbing license and no more than 15 crab on each vessel.
Question: If crabbing for females was aloud, only for recreational crabbing, and only at females maximum size, would this drop the population of Dungeness crab too much? or would it not affect the population significantly?
