Newfisherman, each area that you are fishing will have different regulations.. these regulations tend to change from year to year... The (regs) regulations can be a little difficult to read and understand at first until you get used to them... and some area's have complete closures and protected areas which never open..
So its very important to figure where exactly these closures are and where your fishing...
The other thing to mention is...
Its a good idea to familirize yourself with the different species of Rock fish, Lingcod, greenlings etc.. each have a specific age at which they reproduce, and sometimes they need to be quite old to become mature enough to spawn...
Also in most cases taking the largest rock fish or Lingcod isnt the best eating, but they have the best reproduction abilities... So taking medium siezed bottom fish isnt a bad idea, rather than the monsters...
This helps to ensure that rockfish and other bottom fish have a chance to flurish and not get depleated in your fishing area...
Lots of info for you in the Saltwater Regs and online as mentioned earlier...
Good luck....
