To understand the potential enhancement value of a habitat-loss mitigation reef in Delaware Bay, especially as a source of food for fishery resources, the secondary productivity of the reef epifauna and nearby sand infauna was estimated and compared. The mean production of natural sand infauna was estimated at between 215 and 249 kcal m2 yr−1, while that of the epifauna on the reef surfaces was between 3990 and 9555 kcal m2 yr−1. With the 36 m2 footprint of a reef unit as a basis for comparison, the 407 m2 of reef unit surface covering that footprint produced 1.62–3.89×106 kcal yr−1 of epifauna compared with 7.74–8.96×103 kcal yr−1 per footprint area for the adjacent sand infauna. There was, however, substantial annual variability in the productivity of the epifauna, based on the recruitment success of Mytilus edulis.
