Washington State size limits cover 3 areas. Puget Sound, (Marine areas 5-13) minimum size 6 1/4 inches. Columbia River, 5 3/4 inches. Pacific Ocean, (Marine areas 1-3) 6 inches. :? And this is for just Dungeness crab. Red Rock crab is minimum 5 inches in all areas. That's easy. But then there is the sex and hardshell condition!!
Crab pots have different escape rings size for the Columbia River. Minimum 4 inches there, other areas, 4 1/4 inches.
If I were looking to buy pots at the SBS, I would take my state regs and a tape measure to make sure the pot that is being sold is legal in your state, and the area of the state you are going to crab.
There are some nice pots for sale at the show. My favorites are the collapsible ones that Popeye Marine from Everett sells. He gets them out of Canada and usually sells out during the show. The large one is 16 by 32 inches and sells for $79.95. His main market is to kayakers, but they work great for cruising on a C-Dory. Robbi
