PROBLEM Comprehensive environmental assessments of coastal engineering projects evaluate beneficial as well as detrimental impacts. In the case of rubble-mound structures e.g., jetties, groins, breakwaters, etc., one beneficial aspect of construction is the creation of artificial reef habitat. This is evidenced by the popularity of coastal rubble-mound structures as recreational fishing spots. Few studies, however, have examined the utilization patterns of these structures as shelter, foraging, spawning, or nursery habitat by fish and invertebrate populations. Consequently, a lack of documentation of beneficial impacts of rubble-mound structures exists. BACKGROUND Construction of rubble-mound jetties at Murrells Inlet, South Carolina was completed in April, 1980 Figure 1. A series of pre-, during, and post-construction field studies have been conducted to determine short and long-term effects of construction on local macrobenthic communities Knott et al. 1984 and colonization of the structures by attached and motile fauna and flora Van Dolah et al. 1984. A third field investigation was conducted between April, 1985 and February, 1986 to supplement the results of the prior studies. Specific objectives were to 1 document fish species composition, abundance, and seasonal occurrence, 2 assess seasonal abudance of commercially and recreationally important crabs, 3 determine if different portions of the jetties supported different fish populations, 4 characterize the food habits of fishes captured on or near the structures, and 5 evaluate the recreational fishery supported by the jetties.
