The National Environmental Policy Act of 1969 requires federal agencies to examine the environmental effects of their proposed actions. On behalf of the Department of Defense, the Department of the Navy is preparing this Draft EIS/OEIS to assess the potential environmental effects associated with the proposed military activities. The Navy is the lead agency for preparation of this Draft EIS/OEIS. The Office of the Secretary of Defense directed the Navy to establish a Joint Guam Program Office that serves as the NEPA proponent of the proposed actions. A number of federal agencies were invited to be cooperating agencies in the preparation of this Draft EIS/OEIS. These agencies have either jurisdiction or technical expertise for certain components of the proposed actions or a potentially affected resource. The agencies that have accepted the invitation to participate as cooperating agencies are United States (U.S.) Fish and Wildlife Service, Department of Transportation Federal Highways Administration, Federal Aviation Administration, U.S. Environmental Protection Agency Region 9, U.S. Office of Insular Affairs, U.S. Department of Agriculture, U.S. Army Corps of Engineers, and U.S. Air Force.

Recent studies have shown that many coral reefs are capable of yielding a total fish catch of 18- 24 T.Km-2 (Hill, 1978; Alcala, 1981; Munro, 1987). There are, however, no estimates for the productivity and yield of fishes associated with coral reefs in French Polynesia. This study was designed to determine the fisheries yield from a part of the fringing reef on the island of Moorea, French Polynesia.

In a typical High Island coral reef complex of French Polynesia (transect of Tiahura, Hoorea Island, Society Archipelago!, 73 species of decapod Reptantia and stomatopod crustaceans were collected. Over 9 stations localised along the transect, 3 different units of hard coral substrate of simi1ar volume (about 17 litres each), were sampled at each station. The results are discussed from two aspects : the first shows that at least 50 carcinologic species occur within the cavitary biotopes ; 16 species (mainly Xanthid crabs), represent more than 90% of all collected individuals. Most of the dominant species are widely distributed along the transect (Chlorodiella barbata, Pilodius pugil, Lipcarpilodes integerrimus, Galathea aculeata), and locally, some others are numerically important (Chlorodiella Laevissima, Globopilumnus globosus, Daira perlata,Phymodius ungulatus, etc.). The second aspect concerns the repartition of species in the different biotopes in relation to their feeding habits. Based on the functional morphology of chelipeds, mouth-parts and gastric sill, and on gut content analysis, the species were placed into 5 MORPHO- LOGIC GROUPS : filter-suspension feeders, omnivores/herbivores, omnivores/carnivores, generalised omnivores and predators. The feeding habits and the distribution pattern of abundant species suggest that trophic and habitat partitioning say exist. The predominant species show either different nutritional modes, or inhabit different areas and/or biotopes. Distribution patterns of the morphologic groups ip the different substrates are proposed, and schemes of interspecific relation; are analysed.
