Abstract

A preliminary study on marine snails harvest (Gastropods) has been done in Krakal beach, Yogyakarta, during October to December 2003. Krakal beach has become an underpressure habitat since tourism industry occurred all over Indonesia. Marine snails have been harvested for over two decade but there is no study regarding the effect of this activity. This study aims to elucidate the number of species harvested, the number of each species collected, juvenil and adult, the dominant species, and hypothesize the exploitation status. Fourty species were found, 32 of these population harvested were dominated by the young. Harvest volume was about 3146 per month. These results indicate an overexploitation status.

Abstract

Mungkin terlalu idealis harapan saya agar penyelenggara negara bisa menerapkan anjuran-anjuran yang dituliskan dalam buku ini. Namun seperti banyak harapan lain yang digantungkan pada pemerintahan baru ini, tidak berlebihan kiranya bila setidaknya departemen yang berkepentingan dan yang berkaitan (semua pihak) memiliki pengetahuan dasar yang kuat sebagai landasan fikir bagi pembuatan keputusan strategis yang dibuatnya bagi keberlanjutan negara ini. Dengan kata lain sudah saatnya negara ini mengubah pendekatan pembangunan yang direncanakan. Alangkah bahagianya bila Indonesia memiliki pemimpin-pemimpin yang mau belajar.

Abstract

Nudibranchia is the largest order of Opistobranchia which is known to have about 3,000 species. Nudibranchia is a popular macro photography object among divers. Although Tulamben Waters, Bali is one of popular destination for macrobiota’s habitat, but research on marine biota, especially nudibranchia in these waters is still very rare. This study uses two methods, which is direct observation to reveal diversity and species number, belt transect methods to estimate density or abundance per sampling area using diving techniques . A transect line of 50 m at each point of observation site was used to evaluate abundance. This study wants to see the level of diversity, mapping various species and abundance of nudibranchia. For biodiversity, 31 species from 15 families are found, Chromodoridae, Dorididae, Elysiidae, Facelinidae, Flabellinidae, Goniodorididae, Halgerdidae, Hexabranchidae, Phyllidiidae Polyceridae, Hydatinidae, Costasiellidae, Elysiidae and Limapontiidae. Whereas the transect method found 12 species from 6 families, Chromodoridae, Facelinidae, Phyllidiidae Aglajidae, Costasiellidae, and Elysiidae. With a diversity index of 2.27 and the highest level of abundance found in Pteraeolidia ianthina species with a relative abundance of 0.19%.
