Hey Gidge, those bright orange fish are called Sebastes ruberrimus, or Yellow-eye Rockfish. You have to keep every yellow-eye rockfish you catch, since bringing them to the surface kills them. According to the Alaska Department of Fish and Game, certain species of rockfish have a special type of swim bladder with a unique gas-producing and absorbing gland, which allows a fluctuation in the quantity of gas within the swim bladder. This helps the fish maintain boyancy at various depths. When reeled to the surface, the fish is unable to absorb the gas in the swim bladder fast enough; the change in pressure as it nears the surface kills the fish.

Other species, such as dusky and black rockfish don't have this unique gland. They survive the trip to the surface, but ended up on my dinner plate just the same.
