KEANEKARAGAMAN SPESIES DAN KARAKTERISTIK HABITAT KERANG KIMA (Cardiidae: Tridacninae) DI EKOSISTEM INTERTIDAL TANJUNG BILIK TAMAN NASIONAL BALURAN

Abstract

Kima (Giant clam) is a group of sea shells that belongs to the cardiidae family and the Bivalvia class. Kima is one of the international trade commodities with high economic value. This heterogeneous habitat condition is interesting to study, especially in order to understand the habitat characteristics and species diversity of clams in the intertidal zone of the Baluran National Park chambers. To determine the characteristics of the habitat selected by the clam shell population and species diversity, a road sampling method was carried out by 'tracking' the habitat types and the Habitat characteristics analysis using coral reef classification. The most preferred habitat characteristics for clams are RCK (rocks) with a percentage of 64.28% and the lowest is S (sand) with a percentage of 3.57%. The diversity of species of clams in the intertidal zone of Bilik TNB beach is low, numbers 4 species were found, namely Tridacna crocea, T. maxima, T. squamosa and Hippopus hippopus. The evenness value shows a result that is close to zero, which means that there are species that dominate in the clam shell community, namely T. crocea, which number reaches 38 individuals.

Ecological potential of giant clams in Ambon Island waters, Eastern Indonesia

“…The absence of H. Hippopus in Morella waters could be attributed to the substrate in this location which is predominantly by massive coral while in Suli waters predominant substrate is sand where H. Hippopus was found. Previous studies showed that H. Hippopus only found in the sand substrate [16,17]. Species composition and the number of species found in this Ambon Island waters is similar to the giant clams found in Tanjung Bilik, Baluran National Park [17] but lesser than the number of species in Kei Island (5 species) [7] and Kei Kecil waters (6 species) [18].…”

The species absence compared to Kei Island is T. noae while to Kei Kecil are T. derasa and T. gigas.…”

Profil Ekosistem Terumbu Karang di Intertidal Pantai Balekambang, Kabupaten Malang, Jawa Timur

“…Di beberapa frame foto juga ditemukan kima atau Tridacna sp. Keberadaan kima yang terdapat pada Pantai Balekambang merupakan mikroba indikator pencemaran lingkungan, yang menunjukkan bahwa meskipun aktivitas antropogenik cenderung mengganggu keberadaan terumbu karang, tetapi kondisi kejernihan air laut tetap terjaga dan terbebas dari bahan pencemar (polutan) (Setiawan et al, 2022).…”

Hubungan kondisi tutupan terumbu karang dengan kepadatan megabentos di perairan Pulau Talam Kabupaten Tapanuli Tengah Provinsi Sumatera Utara

“…Pulau Talam merupakan pulau yang jauh dari pemukiman sehingga sangat mendukung pernyataan Elfwing et al dalam Setiawan et al (2021) yaitu kima sangat rentan terhadap perubahan lingkungan dan memilih habitat dengan kondisi air laut yang jernih dan bebas dari pencemaran di wilayah intertidal maupun subtidal. Adapula bulu babi merupakan organisme yang dapat hidup berdampingan dengan terumbu karang tanpa menimbulkan kerugian, tetapi dengan meningkatnya populasi bulu babi akan mempengaruhi terumbu karang yang dapat mengakibatkan kematian karang muda (COREMAP LIPI dalam Bangapadang, 2019).…”
