hehe I had the same problem , I`ve caught a few in Richmond on a rod while was fishing for a white fish , I was surprised to see them at first , so I took a picture , DFO were going on a boat few times a day and checking all shore in Richmond at that time (was about 1.5-2 months ago) . So I asked the guys on a boat about cray fish , they told me the last time they saw one in this area was around 8 years ago , and asked me for a picture , after looking at it they asked to send it to them by email which I did . After few days waiting for the same answer you asked , I went to DFO`s office at Steveston , and ask a guy at reception , he was confused too , but after a few minutes he pointed me to the table(list) of the fish species - at the bottom there is a note , if its not listed here , u can keep 20 a day . Same idea with peamouth chubs and pike minnows
