Donít know about reef balls off So. Cal. I have heard that they are moderately productive in some Florida/East Coast sites, but I believe they are typically placed adjacent to an existing, healthy coral reef and serve as additional structure. I have my doubts as to their benefits in local waters. I say this because the Fish & Game concrete fish shelters that Max thoughtfully provided an image of are still kicking around and (having dived them many times) are amazingly unloved by our local fish population. There are a number of them off Sunset and some more - maybe 40 or so - on the Santa Monica Artificial Reef. They are rarely occupied, though other pipe, concrete and rock structure nearby usually holds a good population of calico, sand bass, Sargo, perch and Blacksmith. The so-called fish shelters are similar in structure to the reef balls, and because of that I would question the effectiveness of them. I would also note that you havenít seen them used in any reefing projects since about the 60ís and though not stated anywhere, It seems that F&G came to the same conclusion. I would suggest that since they do not provide any nooks and crannies for inverts and juvenile fish, they are found to be wanting as structure for fish/invert habitation.
