Abstract

The genus Crassostrea has an important role for community life in coastal and mangrove ecosystems. In this article, we try to review in detail the ecology, biology, and ecological functions of Crassostrea spp. Furthermore, we also review about 25 species of Crasostrea that exist in the world and also have a high level of adaptation. Based on ecological functional, Crassostrea acts as an efficient engineer of ecosystems, where in forming ecosystems, in nutrient cycling, in reducing anthropogenic eutrophication, shelter area, breeding grounds, and as a link between benthic-pelagic. In addition, high Crassostrea communities can form reefs and serve as ecologically important for diverse species.Keywords:Marine BivalvesCommunity Anthropogenic EcosystemsFunctional

Abstract

Study on the length-weight relationships and condition factors of oyster (Crassostrea gigas) has been done in Tibang and Ulee Lheue estuary areas, Banda Aceh for 4 months starting from July to October 2017. The objective of the study was to observe the condition of oysters in Banda Aceh City. The sampling method used line transect, where each sampling location is divided into 3 stations. Length-weight relationship analysis was performed using Linear Allometric Model (LAM). The result of the analysis of Length-weight relationship in Tibang and Ulee Lheue waters of Banda Aceh City shows the average value of 1.92 and 1.97 (negative allometric). The K value shows at Tibang location (5.07) higher than Ulee Lheue (4.98). Based on the mean value Wr indicates that Ulee Lheue (103.92) has a higher value than Tibang (102.60). The conclusion of K and Wr values shows that the environment in the research location is still stable, so it can be concluded that Tibang and Ulee Lheue waters can still support the life of oysters.Penelitian tentang hubungan panjang berat dan faktor kondisi tiram (Crassostrea gigas) telah dilakukan di kawasan estuari Tibang dan Ulee Lheue, Kota Banda Aceh selama 4 bulan dimulai dari Juli hingga Oktober 2017. Tujuan penelitian adalah untuk melihat kondisi tiram di Kota Banda Aceh. Metode pengambilan sampel dilakukan dengan transek garis, dimana pada setiap lokasi sampling dibagi atas 3 stasiun. Analisis hubungan panjang berat dilakukan menggunakan Linear Allometric Model (LAM). Hasil analisis hubungan panjang berat di perairan Tibang dan Ulee Lheue Kota Banda Aceh menunjukkan nilai b rerata 1,92 dan 1,97 (alometrik negatif). Adapun nilai K menunjukkan rerata pada lokasi Tibang (5,07) lebih tinggi berbanding Ulee Lheue (4,98). Berdasarkan nilai rata-rata Wr menunjukkan bahwa perairan Ulee Lheue (103,92) memiliki nilai lebih tingi bebanding perairan Tibang (102,60). Adapun kesimpulan nilai K dan Wr menunjukkan keadaan lingkungan pada lokasi penelitian masih dalam keadaan stabil, sehingga dapat disimpulkan perairan Tibang dan Ulee Lheue masih dapat mendukung kehidupan tiram.
