Abstract

 Walaupun wilayah laut dan pesisir sangat penting untuk kehidupan rakyat dan bangsa Indonesia, secara nyata perairan Kendari belum digarap secara optimal, terutama kondisi dan potensi perikanan, khususnya kepadatan dan keanekaragaman krustasea. Penelitian ini bertujuan untuk mengungkapkan dan mengidentifikasi potensi sumber daya laut di pulau-pulau kecil disekitar perairan Kendari. Penelitian dilakukan dengan cara koleksi bebas menyusuri mangrove. Data yang diambil dari penelitian ini adalah data krustacea non ekomomis dan ekonomis serta data pendukung  lingkungan (suhu, pH dan salinitas). Hasil penelitian menunjukkan parameter lingkungan di beberapa lokasi masih relatif baik untuk kehidupan krustasea di daerah mangrove. Diperoleh 377 individu, 15  jenis, 12 famili dan 1 ordo individu krustasea. Kepadatan krustasea di setiap lokasi berbeda-beda. Indeks keanekaragaman (1,121-3,744) dan indeks keseragaman (0.360-0.610) termasuk sedang, yang menggambarkan bahwa penyebaran individu relatif sama serta indeks dominansi pada penelitian ini termasuk tinggi (0,190-0,620). Dengan diperolehnya data keanekaragaman krustasea di perairan Kendari sudah sepatutnya harus lebih dicermati lagi kondisi lingkungan dan keberadaan krustasea secara periodik karena krustasea merupakan salah satu rantai makanan yang juga penting di dalam ekosistem pesisir. Kata kunci: Krustasea, keanekaragaman, mangrove, perairan KendariAlthough the marine and coastal areas are very important for the life of the people and nation of Indonesia, Kendari waters significantly have not worked optimally, especially the condition and potential of fisheries, particularly the density and diversity of crustaceans. This study aims to reveal and identify the potential of marine resources in small islands around the waters of Kendari. Research carried out by way of free collection along the mangrove. Data from this study are from non economical, economical crustaceans and environmental data (temperature, pH and salinity) as well as to supporting the environmental. The results shows several areas of environmental parameters is still relatively good for the life of crustaceans in mangrove areas. Provided 377 individuals, 15 species, 12 families and 1 order of individual krustaseans. Krustasean densities at each location is different. Diversity index (1.121-3.744) and Similarity index (0,360-0,610) catagories in medium grade, which illustrates that the spread of crustacea is relatively the same. Index of dominance in this study was high (0.190-0.620). By obtaining data of  diversity crustaceans in the waters of Kendari, should be more rutiny and  should have been more better protecting the environmental conditions and also the presence of crustaceans periodically because crustaceans are one of the food chain are also important in the coastal ecosystem.Key words: Crustaceans, diversity, mangrove forests, waters Kendari

Abstract

Perairan Kepulauan Matasiri dipengaruhi oleh daratan Pulau Kalimantan (mainland) dan Selat Makassar.Kedua pengaruh  tersebut  menyebabkan  adanya  perbedaan  karakteristik  habitat  yang  diduga  berdampak  pada distribusi spasial krustasea.Metode deskriptif diterapkan pada penelitian ini. Krustasea disampling dengan metode sapuan menggunakan alat tangkap trawl demersal pada 4 stasiun yaitu, Stasiun 1, 2, 3 dan 4. Parameter fisika kimia perairan (meliputi salinitas, suhu, kedalaman, kecerahan, kekeruhan, TSS, oksigen terlarut,  pH,  phospat,  nitrogen,  dan  silikat)  semua  diukur  dengan  menggunakan  alat  CTD (Conductivy Temperature Depth) 911 Plus. Pengukuran pH menggunakan SBE (Sea Bird Electronik) 18 pH, kecerahan dengan alat CStar Transmissometer dan kekeruhan menggunakan OBS3 (Optical Backscatter Sensor).Data dianalisis  menggunakan  metode  statitik  multivariabel  yang  didasarkan  pada  Analisis  Komponen  Utama (Principal Component Analysis, PCA) dan Analisis Korelasi (Corresponden Analysis, CA).Hasil analisis PCA menunjukkan bahwa habitat dapat dikelompokan menjadi tiga karakter, yaitu kelompok habitat dekat estuaria (Stasiun1 dan 4), kelompok habitat sebelah utara Kepulauan Matasiri (Stasiun 2) dan kelompok habitat sebelah selatan Kepulauan Matasiri (Stasiun 3).Kelimpahan krustasea sangat dipengaruhi oleh parameter salinitas, kecerahan, dan kedalaman. Hasil analisis CA menunjukkan bahwa terdapat perbedaan distribusi spasial jenis krustasea.  Beberapa  famili krustasea  seperti  Paguridae  dan  Dromiidae  hanya  ditemukan  di  Stasiun 4, sedangkan famili Alpheidae, Parthenopidae, dan Podophthalmidae hanya dapat ditemukan di Stasiun 3. Hal ini menunjukkan perbedaan karakteristik habitat mempengaruhi kelimpahan jenis krustasea tertentu.  Kata kunci: krustasea, kelimpahan, karakteristik habitat, distribusi spasial The Matasiri Island waters influenced by the mainland island of Borneo and the Makassar Strait. Both impacts cause the differences of habitat characteristics of Matasiri Islands waters, which affects the differences of spatial distribution of crustacean. Descriptive methods applied in this study. Crustaceans sampled with a  sweep method using demersal trawl gear in the four stations are: Station 1, 2, 3 and 4. Aquatic chemical physics parameters (including salinity, temperature, depth, brightness, turbidity, TSS, dissolved oxygen, pH, phosphate, nitrogen, and silicate) were all measured using a CTD (Conductivy Temperature Depth) 911 Plus. Measurement of pH using SBE (Sea Bird Electronic) 18 pH, the brightness using CStar Transmissometer and turbidityusing OBS3 (Optical Backscatter Sensor).Datawere analyzed using multivariable statistic method based on the Main Component Analysis (Principal Component  Analysis, PCA) and Correlation Analysis (Corresponden Analysis,CA). The results of PCA analysis showed that the habitat can be grouped into three characters, namelynear the estuary habitat groups (Stations 1 and 4), the habitat north of Matasiri Islands (station2) and the habitat south of Matasiri Islands (station3). Abundance of crustaceans is strongly influenced by the parameters of salinity, brightness, and depth. CA analysis results indicate that there are differences in the spatial distribution of crustacean species.  Several families of crustaceans such as Paguridae and Dromiidae only found in  the Station 4,while the family Alpheidae, Parthenopidae, and Podophthalmidae only be found at Station 3. This suggests differences in habitat characteristics affect the abundance of certain crustaceans.  Key words: Crustacea, abundance, habitat characteristics, spatial distribution

Abstract

Coral shrimp (Panulirus spp.) or known as lobster is a potential fishery commodity and economic value. The demand for domestic and export market continues to increase both as local consumption and export. Indonesia is the largest lobster fishery producer in almost all Indonesian waters, from the west coast of Sumatra to the east coast Jayapura, one of which is Pameungpeuk beach, South Garut, West Java. As a result of increasing demand, fishermen try to catch as many lobsters and the impact of lobster prices also in creases and whereas fishermen continuously take it from nature. This study was conducted to determine the diversity and potential of lobster species especially living in high wavy waters along the southern coast of Garut (Pamengpeuk), West Java.The results of observation are only three types of crayfish, namely: a. Panulirus homarus (green lobster sand); b. Panulirus longipes (lobster flower/ red lobster) and Panulirus versicolor (green lobster/bamboo); is most commonly found in the area of south Garut, Pameungpeuk beach with high and strong waves. The percentage of female P longipes species (42.88%) was higher compared to male P. homarus (40%) and ovigerous female of P. versicolor (37.14%). While the sexual ratio between P. homarus (1:2.0:2.0); P. longipes (1:1.2:1.0) and P. versicolor: 1:1.2:1.2  which statistically showed significantly different p <0.05.
