Qualitative observation of substrate cover made by visual observation with tow manta taw method of habitat profile. As for quantitative observations
made with the method of Line Intercept Transect LIT with some modifications COREMAP CRITIC-LIPI 2004. Transects carried out by pulling the ribbon
roller meters along the 70 m parallel to the coastline and the beach is the position of the left divers. Then UL set on the line transect with three replications namely:
0-10 m, 30-40 m and 60-70 m. All the biota and substrates that offensive line transect was noted with accuracy approaching centimeters, divided by transect
length Figure 4.

3.4.1.1. Water Quality
Coral reef ha e significant value not only of social and economic side but also from the biological, chemical and physical functions that can determine the
sustainability of life coral reef ecosystems in coastal areas. To determine the condition of waters in coastal areas of the island Liwitongkidi, Siompu and
Kadatua necessary measurements to parameters associated with the research. More details can be seen in Table 4.

Coral Fish Community
Collecting data on reef fish communities in research sites using Line Intercept Transect survey method LIT. Transects carried out by pulling the roller
meter of length 70 m transects placed parallel to the coastline and 2.5 m wide either side of the transect line so that the broad field of visualization of fish per
transect is 350 square meters at depths of 30-10 m. Data collection was done on coral reef fish on the east side, west, north and south island to island Kadatau
Liwutongkidi while on the south side and north of the siompu island in Figure 5.
Figure 5. Technique data collecting fish with underwater visual census UVC Fish species in the data location of the study and classified into 3 groups based,
English at al. 1977, namely: 1. Target Fish. Fish which is a target for cacth or more known as an important
economic fish or fish consumtion i.e; family Serranidae grouper, Lethrinidae, Nemimpteridae, Lutjanidae snapper, Scaridae, Acanthuridae, Mulidae,
Siganidae, and Haemulidae sweetlips.
2. Fish Indicators. As a determinant of fish to coral reefs because the fish is close to do with the fertility of coral reef fish from the family of Chaetodontidae
3. Other fish Major Family. These fish are generally in the number of lots and lots of sea water as the ornamental fish Pomacentridae, Caesionidae, Scaridae,
Pomacanthidae, Labridae , Apogonidae cardinal fishes and others
