well, unlike other types of fish or shark species most swim bladders kill over half the population of fish in the world so that tells you what swim bladders do nothing. And gills are to help the fish breath so we have lungs to breath out of fish have special under water lungs so really fish don't have much to worry about under the ocean other than getting killed.
