“…In total, 22 individuals of Diopatra were examined. The lower number of individuals examined from Jeruklegi (2) was because most of the individuals collected from this village had been used in the study by Wibowo et al (2022). We found that all of these solitary tubeworms were identical to D. claparedii Grube, 1878.…”

Diopatra claparedii Grube, 1878, is a common polychaete species that occurs in Southeast Asian countries, including Malaysia, Singapore, Thailand, and the Philippines. However, the occurrence of this species in Indonesia has never been recorded. In the present study, we identified the presence of D. claparedii in the eastern part of the Segara Anakan Lagoon in Cilacap, Central Java Province. Thespecies is characterized as having distinct pectinate chaetae with funnel-like combs. The worms, like in some other Asian countries, are commercially exploited for use as fishing bait. The distributional map of this species is provided in this article.

“…(present study) also have the potential for use as feed in aquaculture due to their relatively high protein and fat contents. The latter two species, however, are still poorly studied despite an initial research on some biological aspects of Diopatra by Wibowo et al (2022). The identity of these three Javanese species also remains unknown to date that further taxonomic investigations are required; they may represent new records or even new species considering that polychaete taxonomic studies in the southern coast of Java have been limited (Pamungkas and Glasby, 2019).…”

“…Other Asian species include D. aciculata (Knox and Cameron, 1971) and D. sugokai (Izuka, 1907), in Japan, as well as D. claparedii Grube, 1878, in Malaysia. In Cilacap, Central Java Province, Indonesia, Diopatra worms are also used as fishing bait by local anglers (Wibowo et al, 2022) the animals are called 'lur umah' in the local language, which means a worm with housing. The worms were initially identified as D. neapolitana by Purwati et al (2020), but the occurrence of this European species in Indonesian waters is highly unlikely considering the long distance between the two geographic regions.…”

Sexual Maturity and Macronutrient Contents in Diopatra sp. (Onuphidae, Polychaeta) Maintained at Different Salinity Levels

et al. 2023

View full text Add to dashboard Cite

Diopatra sp. (Onuphidae, Polychaeta) is an economically important polychaete species commonly used as a fishing bait by local anglers in Cilacap, Central Java Province. Some biological aspects of this local species, however, have not been studied yet. The aim of this research was to see the effect of salinity levels on the sexual maturity and the macronutrient contents of the animals. Diopatra specimens in the present study were collected from the intertidal mangrove habitats of Jeruklegi Village, Cilacap, in sexually immature condition. The worms were then transported to the laboratory and were maintained in containers with four different salinity levels, i.e. 10, 15, 20 and 25 ppt over the next two months. The sexual maturity of the animals were observed based on the presence or absence of coelomic gametes. Proximate analysis was performed to determine macronutrient contents of the animals. The effect of salinity levels on the animals' sexual maturity and macronutrient contents was analyzed using one-way ANOVA. The results showed that salinity levels did not significantly affect the sexual maturity level of Diopatra worms (p > 0.05). Similarly, they did not affect the protein and fat contents, but impacted the carbohydrate content of the animals (p < 0.05). The protein and the fat contents in Diopatra sp., i.e. 41–43% and 6–9%, respectively, met the amount required to be used as shrimp broodstock and fish feeds. While the species has the potential for use in local aquaculture, the annual reproductive cycle as well as the identity of the species, however, require further research.

Polychaeta Diopatra sp. banyak ditemukan di daerah kawasan mangrove Cilacap dan banyak dimanfaatkan sebagai umpan. Pengambilan polychaeta secara masif dari habitatnya untuk tujuan komersial dianggap tidak berkelanjutan bagi lingkungan, karena berkontribusi pada menipisnya sumber daya alam. Pemanfaatan cacing ini sebagai umpan sudah banyak dilakukan tetapi masih belum banyak informasi tentang kandungan nutrisinya, sehingga perlu dilakukan studi tentang kandungan nutrisi cacing Diopatra sp untuk dimanfaatkan menjadi bahan pakan udang di wilayah ini sebagai informasi usaha pengembangan budidaya. Penelitian ini dilakukan dengan metode survei. Pengambilan sampel dilakukan di daerah mangrove Jeruklegi kabupaten Cilacap dalam empat stasiun dengan tiga titik pengambilan sampel dan pengulangan tiga kali setiap dua minggu sekali. Hasil penelitian menunjukkan bahwa kandungan nutrien cacing Diopatra sp. dari empat stasiun pengambilan tidak berbeda nyata (p>0,05), dengan kandungan protein rata-rata 51,07-53,66%, kandungan lemak rata-rata 6,46-9,52% dan kandungan rata-rata karbohidrat 6,47-7,55%. Kandungan makronutrien Diopatra sp. berpotensi menjadi bahan baku pakan untuk memenuhi kebutuhan protein dan lemak budidaya udang dan ikan. Polychaeta Diopatra sp. is commonly found in the Cilacap mangrove area and widely used as bait. Massive exploitation of polychaeta from their habitat for commercial purposes is considered unsustainable for the environment, as it contributes to the depletion of natural resources. The use of these worms as bait has been widely carried out but there is still not much information about their nutritional content, so it is necessary to study the nutritional content of Diopatra sp. worms to be used as shrimp feed ingredients in this region as information on aquaculture development efforts. This research was conducted by survey method. Sampling was carried out in the Jeruklegi mangrove area, Cilacap district in four stations with three sampling points and repeated three times every two weeks. The results showed that the nutrient content of Diopatra sp. from the four sampling stations was not significantly different (p>0.05), with an average protein content of 51.07-53.66%, an average fat content of 6.46-9.52% and an average carbohydrate content of 6.47-7.55%. Diopatra sp.'s macronutrient content can potentially be a raw material for feed to meet the protein and fat needs of shrimp and fish farming.
