Charlie C got some clunkers offshore when we went to Portland (well I think they were). And that was late in to the season.
Myself, I will only take male fish and for those that are not aware, they tend to have a blue flash across the head. Females tend to be brownish, so on my boat, anything inbetween goes back too.
Minimum legal landing size is 23cm according to the Southern Sea Fisheries website: http://www.southern-ifca.gov.uk/byelaws
Seems a little small, think I would raise that myself.
