Abstract

The scleractinian coral Pocillopora damicornis was abundant in both southern and northern of Panjang Island, Central Java. The aim of this study was to observe the colony distribution and population structure of coral P. damicornis at Panjang Island, Central Java. Quadrates transect (4 x 4 m) were applied in eight census lines perpendicular to the seaward edge of the coral zone. For the study of coral density and colony size-frequency distribution, the quadrates transects also placed parallel with shoreline in northern and southern sites of Panjang Island. The coral was occurred from 0.4 to 5 m water depth and most abundant in the front reef zone of the southern site. The maximum density was occurred in southern site (1.06 colony/m2), with aggregated at the 117-184 m on the census line. Coral size in terms of maximum diameter ranged from 1 to 35 cm with an average 12.76 ± 7.3 cm in southern site and 17.7 ± 10.76 cm in the northern site. The study showed that coral colony size-frequency distribution of P. damicornis was different between southern and northern site.

Abstract

The objectives of the research were to know the production of hatchery, survival rate and growth rate of fry. Floating nets  were made for plastics hapa (2 mm mesh size) with 3 different size (5 m2, 10 m2, and 15 m2). The larvae were stocked in different hapa nursery size ( 1 m3, 2 m3, 3 m3) at the rate of 1000 larvae/m3 of water. The fry produced from the first nursery were subsequently reared in waring (mesh size 0,04 cm) at density of 600 fry/m3 of water. The spawning were conducted for 6 months, while larvae rearing were 2 months for each period respectively. The result showed that the hatchery of 15 m2 scale were technically and biologically feasible. During 6 months period it produced 11,870 fingerling of 40 gram, 3,028 fry of 4 gram and 4,290 of larvae. The survival rate and growth rate of fry water not significantly affected by different hapa size either in the first and second nursery. The survival rate of the first nursery was 64.70-72.63% of 5.0-6.8 cm fry, while the second nursery was 97.29-98.30% of 11.5-12.4 cm fry.
