Don't concentrate all your efforts up shallow,most of the larger fish cruise the deeper breaks ,weeds,structure etc. go big with bait,check your terminal tackle often as problems will come up . Always sharpen hooks and have a good pair of jaw spreaders and cutters as it's better for fisherman and fish alike to be fast and efficient with your releases.
Get them back in the drink asap if you are not keeping as the cold temps do a number on gills,eyes,skin.
