“…It was previously believed that the puerulus stage is a non-feeding stage, relying on energy reserves from the previous stage known as phyllosoma [19,20]. However, recent findings using eDNA metabarcoding techniques have detected the DNA of zooplanktonic crustaceans in the stomach content of pueruli, questioning the previous hypothesis [21]. Drawing upon these findings, we suggest that the decreased survival rate observed during the transition period from the puerulus to the post-puerulus stage may be attributed to inadequate nutrient storage, especially lipid, in terms of quantity and quality.…”

The study aimed to assess lobster fry adaptation to a formulated diet over 1-3 days while evaluating the recirculating system's performance. 1,500 pueruli lobsters (average weight: 0.31 ± 0.01 g) were placed in 30 round 80 L tanks for 30 days. Lobsters underwent various feeding strategies: formulated diet only (FD), adjusting 10% fresh diet per day (D1), every 2 days (D2), every 3 days (D3), and fresh diet only (Fr). Each treatment had five replicates. Results showed feeding strategies influenced lobster growth, with survival rates between 23%-29%. The recommended strategy was adjusting 10% fresh diet every three days, yielding the best performance in final weight (0.93 g), weight gain (187%), and specific growth rate (3.5% per day). Initial weeks saw high mortality and moulting during the puerulus to post-puerulus transition. Water quality analysis indicated the phytobiological filter had lower total ammonia nitrogen (TAN), nitrite-N, nitrate-N, and higher pH compared to other filters in use.

Abstract. Masithah ED, Fadhilah MG, Amin M, Nur KU, Musdalifah L, Samara SH, Cahyoko Y, Alimuddin, Alim S, Setyono BDH. 2023. Diversity and abundance of plankton community in Prigi and Tawang Bays, natural settlement habitats of Spiny Lobster larvae in East Java, Indonesia. Biodiversitas 24: 1642-1649. Prigi and Tawang Bays have been well-known as settlement areas for spiny lobster larvae, Panulirus spp., in East Java, Indonesia. These locations may suggest suitable environments including diet availability for lobster larvae. Therefore, the present study aimed to investigate the type and abundance of plankton in both locations to discover potential live diets for lobster larvae. This study also explored plankton’s diversity, uniformity, and dominance indices in both locations. Plankton samples in each location were collected using a plankton net at four depths: 0.3 m, 2.5 m, 5 m, and 20 m with three replicates. The results revealed that 17 plankton species were identified from 0.30 m depth, 13 at 2.5 m, 11 at 5 m, and 13 at 20 m depth at Prigi Bay. In addition, 17 plankton species were discovered at 0.3 m depth, 11 at 2.5 m, 12 at 5 m, and 12 at 20 m at Tawang Bay. Among the most abundant species were Acartia sp., Calanus sp., Paracyclopina sp., and Oithona sp. The diversity indices observed in Karanggongso of Prigi Bay and Tawang Bay ranged from 2.02-2.49 and 2.17-2.65, respectively, within the moderate range. Similarly, the uniformity indices observed at both locations were moderate, ranging from 0.38-0.45 at Prigi Bay and 0.41-0.46 at Tawang Bay. There were no dominant species at both locations, as the dominance index values ranged from 0.13-0.30. Among the identified plankton species, Oithona sp., Calanus sp., Paracyclopina sp., and Acartia sp. are considered potential live feed for lobster larvae, and thus should be further studied.

“…Kajian ini mengambil gap research tersebut dengan objek penelitian biota laut khususnya benih bening lobster. Ditambahkan juga bahwa kajian mengenai bening lobster banyak membahas di ranah ilmu alam (Amin et al, 2022;Diatin et al, 2022;Priyambodo et al, 2020). Maka tulisan ini mengisi kekosongan pengetahuan lokal dalam perlindungan bening lobster dengan pandangan ilmu politik.…”

Tulisan ini bertujuan untuk mengetahui pengetahuan lokal yang dimiliki masyarakat nelayan dalam menjaga keamanan lingkungan khususnya populasi lobster. Dalam tulisan ini difokuskan dengan memotret praktik-praktik yang dilakukan oleh masyarakat nelayan dalam melindungi keberadaan benih bening lobster (puerulus). Argumen utama dalam penelitian ini adalah dengan pengetahuan lokal yang dimiliki oleh masyarakat nelayan menciptakan ekosistem bening lobster yang berkelanjutan. Penelitian ini merupakan kajian kualitatif dengan menggunakan teori Ekologi Budaya dari Julian H. Steward. Teori ini menjelaskan bahwa interaksi manusia dengan lingkungan menciptakan pengetahuan lokal sehingga menjalin hubungan mutualisme diantara keduanya. Data penelitian terdiri dari data primer yang dikumpulkan melalui wawancara mendalam dengan pemerintah, lembaga adat, nelayan, dan pelaku usaha lobster sedangkan data sekunder dikumpulkan melalui jurnal ilmiah dan media massa online. Hasil penelitian menemukan bahwa ada beberapa praktik pengetahuan lokal yang berdampak dalam pelestarian bening lobster yaitu penangkapan bening lobster merupakan kegiatan degradasi progresif terhadap lobster, penjualan bening lobster tidak memiliki nilai instrinsik, pertumbuhan bening lobster lebih baik di alam daripada dipenangkaran, dan penggunaan alat tangkap tradisional dalam menangkap lobster.
