“…The increase in the number of segments and the body weight -both variables had a strong positive correlation (Figure 3) -indicates the animals' growth, and can be affected by several factors such as salinity and feed. A research by Wibowo et al (2019) suggested that the polychaete worms Nereis sp. fed by animal protein had a greater number of segments and weight compared to the worms fed by vegetable protein.…”

Diopatra species are members of the family Onuphidae (Polychaeta, Annelida) that are widely used as fishing bait. These tubicolous worms are common in particular mangrove areas of Cilacap. However, biological aspects of Diopatra sp. inhabiting the areas have not been studied. In the present work, we investigated several biological aspects of the worms, including the segment number, the body weight and the sex ratio, based on Diopatra samples collected from four mangrove habitats of Jeruklegi Village, Cilacap Regency, between June and July 2021. The results show that the average numbers of segments of Diopatra sp. obtained ranged from 195 to 216 segments, whereas the average body weights ranged from 2.03 to 3.12 g, and the average sex ratios ranged from 0.5 to 1.3. In general, the biological aspects of Diopatra sp. between sampling sites were relatively similar; this can be attributed to the similar environmental conditions at all sampling sites, including salinity (25–32 ppt), water temperature (30–32 oC), dissolved oxygen (6.4–8.8 ppm) and pH (7). While Diopatra worm farming is necessary so that local people do not rely on natural catch, a further taxonomic study is required to reveal the identity of this economically important local species.Keywords:Biological aspectDiopatraMangrove habitatPolychaetesTubicolous worms

“…Hasil penelitian menunjukkan bahwa pada salinitas 15 ppt menghasilkan retensi protein yang sama saat diberi pakan berprotein hewani maupun protein nabati, hasil ini menunjukkan bahwa salinitas 15 ppt merupakan salinitas optimum untuk pemeliharaan Nereis sp. hasil ini sesuai dengan penelitian Wibowo et al (2019a) Selama pemeliharaan 2 bulan dengan perlakuan salinitas 5, 15, dan 25 ppt dan pemberian pakan berprotein hewani maupun nabati belum menunjukkan perbedaan dalam perkembangan gonadnya dibandingkan dengan awal perlakuan. Hasil ini menunjukkan Nereis sp.…”

AbstrakPolychaeta Nereis sp. memiliki kandungan asam amino dan asam lemak tak jenuh yang tinggi, sesuai untuk pakan udang dalam meningkatkan pematangan gonad untuk produksi larva udang. Potensi ini mendorong pengembangan usaha budi daya Nereis sp. sebagai pakan induk udang. Usaha ini belum berkembang karena informasi tentang aspek biologi yang mendukung budi daya Nereis sp. masih terbatas. Oleh karena itu, studi tentang aspek biologi Nereis sp. dengan berbagai modifikasi lingkungan dan pakan perlu dilakukan untuk menunjang keberhasilan usaha budi daya Nereis sp. Penelitian ini bertujuan mengetahui pertumbuhan spesifik, retensi protein, dan perkembangan gonad Nereis sp. dari Kawasan Jeruklegi Cilacap dengan salinitas dan pakan yang berbeda. Hasilnya akan digunakan sebagai informasi untuk mendukung budi daya Nereis sp. yang berkelanjutan. Penelitian dilakukan dengan menggunakan Nereis sp. immature dengan dua jenis pakan, pada tiga salinitas yang berbeda (5, 15, dan 25 ppt). Penelitian dilakukan dengan metode rancangan acak kelompok dengan tiga kali ulangan. Hasil penelitian menunjukkan bahwa pertumbuhan spesifik optimum Nereis sp. pada pemeliharaan salinitas 15 ppt dengan jenis pakan berprotein hewani. Salinitas 15 ppt dan pakan berprotein hewani juga menghasilkan retensi protein tetinggi. Salinitas pemeliharaan dan jenis pakan belum mempengaruhi perkembangan gonad secara signifikan. Pemeliharaan Nereis sp. dengan salinitas 15 ppt dan pakan berprotein hewani menunjukkan hasil terbaik.Abstract Polychaeta Nereis sp. has a high content of amino acids and unsaturated fatty acids, suitable for shrimp feed in increasing gonadal maturation for shrimp larvae production. This potential encourages the development of Nereis sp. to meet the needs of raw material for shrimp feed. This business has not developed due to limitations in information about the biological aspects that support the cultivation of Nereis sp. Therefore, some studies about biological aspects of Nereis sp. with various environmental and feed modifications need to be conducted to support the success of its cultivation. This study aims to determine the specific growth, protein retention, and gonad development of Nereis sp. from the Jeruklegi Cilacap area with different salinity and feed. The results will be used as information to support the sustainable cultivation of Nereis sp. Conducted experimentally with a randomized block design method with three replications, the study used immature Nereis sp. with two types of feed that were maintained at three different salinity (5, 15, and 25 ppt). The results showed that the highest specific growth was Nereis sp. in 15 ppt of salinity with animal protein feed. The salinity 15 ppt and animal protein feed also resulted in the highest protein retention. However, the salinity maintenance and type of feed have not significantly affected gonad development. Maintenance of Nereis sp. with 15 ppt salinity and animal protein feed showed the best results.

“…Based on data in 2012 from the Directorate of Aquaculture, the need for frozen Polychaeta imports continues to increase due to undeveloped marine worm cultivation in Indonesia, seen from the total import value of 2,550 tons with a value of US $ 17,973.80 it can be said to be very potential, to be developed in the future (Anonymous, 2012 in Rasidi, 2013). According to Wibowo et al (2019), Nereis sp. Very good for use as broodstock feed for shrimp because there is a high nutrient content and protein source that can improve the quality of gamete cells and the viability of shrimp larvae.…”

“…Previous research has not done much research on marine worms, especially in terms of density in the cultivation of Nereis sp. Some examples of research that have been successfully carried out by Asnawi et al (2018) used a density of 5 individuals / container with a diameter of 50 cm, while research conducted by Wibowo et al (2019) used a density of 10 individuals / container area of 0.06 m 2 or about 167 individuals / m 2 . Therefore, it is important to do research on stocking density because it is closely related to the production and growth rate of cultivated biota, so this research aims to determine the most effective stocking density for survival and increase the biomass of Nereis sp.…”

Nereis sp. including one of the commodities that have high economic value as well as important commodities in the world of aquaculture. The survival rate of organisms affected by good cultivation management include solid spread, feed quality, water quality, parasites or diseases. High spread solids will have an impact on the decrease in growth rate, feed consumption and survival rate. Therefore, the importance of research on solid spread because it is very closely related to the production and growth speed of cultivated biota. This study was conducted to find out the influence of different scatter solids on the growth and life's smoothness Nereis sp. The research was conducted for 35 days of maintenance using marine worm biota or Nereis sp. The method used is an experimental method using a Complete Randomized Design (RAL) with 5 treatments and 3 repeats namely, Treatment 1: solid spread 50 individuals/m2, Treatment 2: solid spread 100 individuals/m2, Treatment 3: solid spread 150 individuals/m2, Treatment 4: solid spread 200 individuals/m2 and Treatment 5: solid spread 250 individuals/m2. Treatment with solid spread 150 individuals / m2 (P3) gives the best influence in improving the growth and survival of Nereis sp. 0.7838 g and 93.33%.
