Recent indicators show corbina populations are improving, based on juvenile fish sampling.
As for the disappearance of corbina in the winter, they may be seeking warmer water by moving further south or into embayments, or perhaps offshore. Unfortunately, movement patterns of corbina are not well understood. Many rockfish species will not survive if caught in deep water and returned to the ocean. Because of changes in internal pressure after the fish is hooked and retrieved from great depths, there is physical trauma to the gas bladder and other internal organs. I only see small ones being caught.
