When it comes to rockfish size does matter on certain fish, see the link below. I dont think there is a size limit on reds, chuckle heads, barber pole, etc ....
Rockfish

The fishery is open to boat-based anglers from March 1, 2015 through December 31, 2015 (see important NOTE at the end of this section). These species may only be taken or possessed3 in waters less than 360 feet (60 fathoms) deep. The daily bag and possession limit is 10 fish in combination of all species within the RCG Complex (includes all species of Rockfish, Cabezon and Greenlings) per person, with a sub-limit on black rockfish (5 per person) and bocaccio (3 per person), also included in the 10 fish RCG Complex aggregate limit.
