Daftar Isi:
- Trematode infection can affect population dynamics of C. mydas in the wild. Diversification and spatio-temporal dynamics of coastal and marine environments in Indonesia can lead to different trematode community compositions among various populations of C. mydas. This study aims to determine the types of trematodes in C. mydas that live in one feeding ground of the Indonesian waters. The research was conducted at the Turtle Conservation and Education Center (TCEC) Serangan, Bali. Nine juveniles C. mydas with the curved carapace lengths between 41 – 66 cm were observed. The turtles are confiscated by the police from a smuggling attempt to Bali, which was previously caught in the waters around Sapeken Island, East Java. Parasite examination was carried out using the Mini-Flotac® coprology technique in combination with Fill-Flotac®. Eggs were identified based on their morphological and morphometric characteristics and the number of eggs per gram (EPG) of feces was calculated according to available technical guidelines. Trematode eggs found were identical to Learedius learedi (Spirirorchiidae), Diaschistorchis pandus (Pronocephalidae), Octangium sagita (Pronocephalidae), and Enodiotrema megachondrus (Plagiorchiidae). The prevalence of L. learedi and D. pandus was 100%, while O. sagita and E. megachondrus were 77.7% and 66.6%. The highest EPG was found in L. learedi (104±57), followed by D. pandus (42±14), O. sagita (32±28), and E. megachondrus (23±19). Statistically, the mean EPG of L. learedi was significantly higher (P<0.05) from the other three types of parasites, while the EPG density of the three types of parasites other than L. learedi was not significantly different (P>0.05). The result provides an up-to-date baseline information on the type and prevalence of trematodes in C. mydas inhabited Sapeken waters of East Java. Similar studies involving turtle populations from other areas are needed to enhance the understanding of the host-parasite dynamics between turtle population stocks from various waters in Indonesia.
- Infeksi trematoda dapat mempengaruhi dinamika populasi C. mydas di alam liar. Diversifikasi dan dinamika spatio-temporal lingkungan pesisir dan laut di Indonesia dapat menyebabkan komposisi komunitas trematoda yang berbeda di antara berbagai populasi C. mydas. Studi ini bertujuan untuk mengetahui jenis-jenis trematoda pada C. mydas yang hidup di salah satu ruaya pakan di Perairan Indonesia. Penelitian dilaksanakan di Turtle Conservation and Education Center (TCEC) Serangan, Bali. Sampel berjumlah sembilan ekor C. mydas remaja dengan panjang lengkung karapas antara 41 – 66 cm. Penyu-penyu tersebut adalah sitaan polisi dari upaya penyelundupan ke Bali, yang sebelumnya ditangkap di sekitar perairan Pulau Sapeken, Jawa Timur. Pemeriksaan parasit dilakukan dengan teknik koprologi Mini-Flotac® yang dikombinasikan dengan Fill-Flotac®. Telur diidentifikasi berdasarkan karakteristik morfologi dan morfometrinya dan jumlah telur per gram (EPG) feses dihitung sesuai dengan petunjuk teknis yang tersedia. Telur-telur trematoda yang ditemukan identik dengan Learedius learedi (Spirirorchiidae), Diaschistorchis pandus (Pronocephalidae), Octangium sagita (Pronocephalidae), serta Enodiotrema megachondrus (Plagiorchiidae). Prevalensi L. learedi dan D. pandus adalah 100%, sementara O. sagita dan E. megachondrus 77,7% dan 66,6%. EPG tertinggi ditemukan pada L. learedi (104±57), diikuti oleh D. pandus (42±14), O. sagita (32±28), dan E. megachondrus (23±19). Secara statistik, rerata EPG L. learedi berbeda nyata (P<0,05) dengan ketiga jenis parasit lainnya, sementara kepadatan EPG ketiga jenis parasit selain L. learedi tidak berbeda nyata (P>0,05). Hasil penelitian ini memberikan informasi dasar terkini tentang jenis dan prevalensi trematoda pada C. mydas yang hidup di Perairan Sapeken, Jawa Timur. Studi serupa yang melibatkan populasi penyu dari wilayah lain diperlukan untuk lebih memahami dinamika hubungan inang-parasit antar stok populasi penyu dari berbagai wilayah perairan di Indonesia.
