Abstract

The length compositions of Stolephorus heterolobus, Stolephorus insularis and Stolephorus  pseudoheterolobus  were observed. S. heterolobus ranged from 25 to 71 mm., S. insularis from 27 to 75 mm and S. pseudoheterolobus from 27 to 67 mm standard length. The  ages  of these  three  species  were estimated. The  asymptotic  length  of S. heterolobus was 97 mm attained at the age of 26 months, S. insularis 86 mm at 26 months and S. pseudohetorolobus 88 mm at 20 months. The highest growth rate of S. heterolobus was at the size group 30 - 80 mm standard length, that of S. insularis was at 30-50  mm, and that of S. insularis was observed to be the lowest. The stomach contents of S. heterolobus and S. pseudoheterolobus   were studied tand were found that the food  of these two  species  was  more or  less the  same. They fed mainly on zooplankton consisting of copepods and other crustaceans.

Abstract

Monthly collections of fishes in a seagrass community on the west of Burung Island, Pari Islands, were made from May 1975 to February 1976. Seventy-eight species of fishes were collected. Number of specimens, size range, and modal size are given for each month for each species. Number of species and specimens were found highest in July. Relative and total abundances of the more numerous species are summarized. Apogon margaritophorus was the predominant species in the fish community of the area. Notes on the spawning of Siganus canaliculatus are presented, since this species attracts the attention of many mariculturists. The separation of these fishes into four groups is also discussed.

ABSTRACTIndication on seagrass decline  has been observed in many places including Barranglompo Island of Makassar. Condition of damaged seagrass has significant impacts to the roles of seagrass as habitat, spawning ground, and feeding ground for various marine organisms and also role of seagrass as carbon absorbent and stocks.  In order to provide a reference for appropriate seagrass management and conservation, it is required data on seagrass habitat.  A research was done in Barranglompo Island, Makassar from December 2010 to November 2011.  Seagrass condition was observed based on McKenzie et al. (2001) and Balestri et al. (2003).  This research showed that large seagrass coverage was dispersed in southern, western and northern sides of the island. Meanwhile, seagrass spesies with wider distribution were E. acoroides, T. hemprichii and C.rotundata.Keywords : seagrass, Barranglompo Island, habitat characteristics ABSTRAKIndikasi adanya penurunan kondisi lamun ditemukan di beberapa tempat termasuk di Pulau Barranglompo Makassar. Kondisi lamun yang rusak berimplikasi terhadap peranan lamun sebagai habitat, tempat memijah dan tempat mencari makan berbagai organisme serta peran lamun sebagai penyerap dan penyimpan karbon.  Sebagai dasar untuk melakukan pengelolaan dan konservasi lamun yang tepat diperlukan data kondisi dan habitat lamun.  Penelitian dilakukan di Pulau Barranglompo Makassar dari bulan Desember 2010 sampai November 2011.  Kondisi lamun diamati berdasarkan McKenzie et al. (2001) dan Balestri et al. (2003).  Penelitian menunjukkan bahwa distribusi lamun yang luas ditemukan pada sisi selatan, barat dan utara pulau.  Jenis lamun yang mempunyai sebaran yang luas adalah E. acoroides, T. hemprichii dan C. rotundata.Kata kunci : lamun, pulau Barranglompo, karakteristik habitat

Abstract

 Lamun merupakan tumbuhan tingkat tinggi yang hidup di laut dangkal. Sebagai tumbuhan, lamun berperansebagai produser primer yang memberikan kontribusi bagi biota laut maupun ekosistem lainnya. Hasil produksiprimer dari lamun akan masuk ke beberapa kompartemen. Namun berapa besar aliran produksi tersebut ke tiapkompartemen masih menjadi pertanyaan. Penelitian bertujuan untuk melihat berapa besar hasil produksi daunlamun yang dialirkan ke kompartemen lain. Penelitian dilakukan di Pulau Barranglompo Makassar selama 4periode yang mewaikili musim hujan, peralihan I, musim kemarau dan peralihan II. Penelitian dilakukanmelalui beberapa tahap, yaitu (1) mengestimasi produktivitas daun lamun, (2) mengestimasi stok karbon daunlamun, (3) mengestimasi besarnya grazing daun lamun oleh bulu babi dan herbivora lain, (4) mengestimasibesarnya produksi serasah daun lamun, baik yang tenggelam di dasar maupun yang terbawa keluar dariekosistem lamun. Hasil penelitian menujukkan total karbon yang dialirkan ke kompartemen lain mencapai2,20% dari stok karbon daun atau setara 81,8% dari produktivitas daun. Aliran produksi melalui serasah yangmelayang sebesar 0,59% dari stok karbon (setara 22,0% dari produktivitas daun), serasah tenggelam 1,36% daristok karbon (setara 50,6% dari produktivitas daun), grazing bulu babi 0,04% dari stok karbon (setara 1,4% dariproduktivitas daun) dan grazing oleh herbivora lain 0,21% dari stok karbon (setara 7,9% dari produktivitasdaun). Dalam konteks aliran produksi, hasil produksi primer lamun paling banyak berkontribusi dalam ekosistemlamun sendiri sebagai serasah, bisa dimanfaatkan oleh detritivore sebagai makanan, terdekomposisi sebagaiunsur hara, atau terkubur sebagai cadangan karbon. Hanya sebagian kecil produksi primer dimanfaatkan secaralangsung oleh herbivora.Kata kunci : produktivitas daun lamun, aliran produksi daun lamun, grazing lamun, serasah lamun
