Abstract

Seagrass is the only flowering plants (Angiospermae) that have the rhizome, leaves and true roots that live submerged in the sea. Seagrass also has an important role as a nursery ground and Spawning ground in the life cycle in the sea. Seagrass beds in the Karimunjawa Islands has broad category of closure medium (33.03 %, BTN Karimunjawa 2005). Increasing community activity and climate change can be devastated to the extreme concern of seagrass Karimunjawa that sustainability should be maintained, it is necessary to do some research and re-checking the condition of seagrass Karimunjawa. Data is collected in October of 2010 in 10 locations including Kampung Ragas, Alang Alang, Merican, Telaga, Legon Bajak, Kapuran, Menjangan Besar Island North and South, Bengkoang Island, and Menjangan Kecil Island. The method used is the quadrant-sized transects (1 x 1 m). The results showed that the Karimunjawa waters has 8 (eight) seagrass species. Seagrass species are often found in the Karimunjawa Islands is the kind of Cymodocea rotundata Karimunjawa and Thalassia hemprichii. Highest percent (%) coverage of seagrass found in the location of Telaga reach 75.9% by Enhalus acoroides. Seagrass beds in the waters Karimunjawa quite good with the percentage Seagrass coverage value of 59.94%.

Abstract

Seagrass ecosystem of high organic productivity, with a high diversity of biota. On these ecosystems, diverse marine life such as fish juvenile, crustaceans, mollusks (Pinna sp, Lambis sp, Strombus sp), echinoderms (Holothuria sp, sp Synapta, Diadema sp, Arcbaster sp, Linckia sp) and worms (Polichaeta) (Bengen, 2001). The research was conducted at 10 stations. Sampling was conducted two times each observation station parallel to the shoreline and perpendicular to the shoreline using a small beam trawl. The results showed that the juvenile was found 27 species from 14 family. abundance average - average is 0.484 ind/m2 juvenile fish and the highest abundance at station 9 with the abundance of juvenile fish reaching ind/m2 1.40 and the lowest abundance found at station 3 and station 10 to the abundance of only 0.04 ind/m2 . The pattern of distribution of juvenile fish species tend to be random this is because in each station has similar characteristics.
