The study was conducted in Lasongko Bay, Central Buton from May 2013-March 2014 with the aim of identifying habitat conditions, size distribution, growth pattern, sex ratio, and spawning season of Podophthalmus vigil (Fabricus 1798). Samplings were done monthly on six stations using a crab gillnet. The results of research showed that P.vigil were generally found on the substrate type of sand clay with the average depth range of 4.61-11.63 m and tended to be found in cloudy locations. The ranges of carapace width of male and female P. vigil were 4.13-12.39 cm and 4.75-11.64 cm, respectively. The result of Mann-Whitney test of body size showed that in P. vigil only carapace width that were found significantly different (P<0.05) between males and females, whereas the body weight and carapace length were not significantly different (P>0.05) between male and female. The growth pattern of the width carapace and body weight relationship in male P. vigil was negatively allometric, whereas in females was positively allometric. The growth patterns of the carapace length and body weight relationship in males and females P. vigil were isometric and negatively allometric, respectively. The sex ratio of P. vigil varied spatially-temporally with total sex ratio of 1:0.74. The spawning season of P. vigil did not last all year.

Information regarding the diversity of bycatch from blue swimming crab fishing operations is important in ecosystem-based management and assessment for Marine Stewardship Council (MSC) certification of crab fisheries in Southeast Sulawesi and Indonesia. However, data limitation becomes major challenges. This study aims to specify the types of bycatch caught from blue swimming crab fishing in Lasongko and Kendari Bay Southeast Sulawesi. This research was conducted in March to September 2019. Data was collected from trap and bottom gillnet fishing by using a purposive sampling method on a monthly basis. Bycatch was categorized into two groups, namely economically valuable and discarded, according to the local fishersâ€™ perception. Information was presented both spatially and temporally. The results show that bycatch consists of 66 species including 41 economically valuable and 26 discarded species. Indices of diversity, evenness and dominance of fish were also discussed to describe the ecological conditions. Accordingly, this bycatch composition is able to support the management and assessment of MSC certification of crab fisheries in Southeast Sulawesi. Keywords: bycatch, fish diversity, blue swimming crab fisheries, Southeast Sulawesi.

ABSTRACT Isognomon isognomum is a bivalve species widely harvested as a local food resource, yet its natural populations show signs of decline. This study aimed to estimate the secondary productivity of I. isognomum in the coastal waters of Tapulaga, Southeast Sulawesi. Field sampling was conducted from September 2024 to February 2025, yielding a total of 360 individuals. Shell length and total weight were measured using a caliper and an analytical balance, respectively. Ash-free dry mass (AFDM) was obtained by combusting dried tissues in a muffle furnace at 600°C for four hours. Density, growth, production, and biomass were analyzed using the Mann–Whitney test, ELEFAN (FiSAT II), and standard ecological productivity formulas. Density analysis showed the highest abundance in December (14 ind/m²) and the lowest in January (9.78 ind/m²). The Mann–Whitney test (p < 0.05) indicated significant differences between December and January compared to other sampling months. Growth parameters revealed an asymptotic length (L∞) of 13.80 cm and a growth coefficient (K) of 0.71. The highest production occurred in the 6.9–7.8 cm size class, reaching 1,181.97 g AFDM/m²/year, while peak biomass (10,703.42 g AFDM/m²) was recorded in the 8.9–9.8 cm size class. The mean P/B ratio was 0.12/year, suggesting a low recovery potential for I. isognomum populations. Keywords: Isognomon isognomum, secondary productivity, Tapulaga coast ABSTRAK Isognomon isognomum merupakan bivalvia yang dimanfaatkan masyarakat sebagai sumber pangan dan cenderung populasinya menurun di alam. Studi ini bertujuan untuk mengetahui produktivitas sekunder kerang I. isognomum di perairan Pantai Tapulaga Sulawesi Tenggara. Penelitian ini dilakukan pada bulan September 2024-Februari 2025. Jumlah sampel yang dikumpulkan selama penelitian sebanyak 360 individu. Sampel kerang diukur panjang cangkangnya dan beratnya masing-masing menggunakan jangka sorong, dan timbangan analitik. Massa kering bebas abu (MKBA) didapatkan dengan membakar daging kering menggunakan tanur selama 4 jam pada suhu 600°C. Data kepadatan, pertumbuhan, produksi dan biomassa masing-masing dianalisis menggunakan uji Mann Whitney, ELEFAN (FiSAT II), dan formula yang telah baku. Hasil analisis kepadatan menunjukkan kepadatan kerang I. isognomum tertinggi pada bulan Desember dan terendah pada bulan Januari dengan nilai masing-masing sebesar 14 dan 9,78 ind/m2. Hasil uji Mann Whitney (p<0.05) menunjukkan ada perbedaan signifikan antara bulan Desember dan Januari dari bulan-bulan lainnya. Parameter pertumbuhan (panjang maksimum dan koefisien pertumbuhan) masing-masing sebesar L∞ = 13,80, dan K = 0,71. Produksi kerang tertinggi ditemukan pada ukuran 6,9-7,8 cm dengan nilai 1.181,97g mkba/m2/thn dan biomassa tertinggi ditemukan pada ukuran 8,9-9,8 cm sebesar 10.703,42 g mkba/m². Nilai rata-rata rasio P/B keseluruhan sebesar 0,12/tahun yang berarti bahwa kemampuan pulih kerang I. isognomum berada dalam kategori rendah.

Ekosistem pesisir khususnya vegetasi mangrove merupakan salah satu ekosistem yang rentan mengalami degradasi akibat perkembangan penggunaan ruang diwilayah pesisir. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk melakukan pendidikan lingkungan kepada generasi muda khususnya siswa sekolah, dan sebagai salah satu upaya untuk merestorasi ekosistem mangrove di pesisir Desa Bokori Kecamatan Soropia Kabupaten Konawe. Kegiatan ini dilakukan dalam beberapa tahapan, yakni penyampaian materi tentang pentingnya vegetasi mangrove dalam menopang sistem kehidupan di pesisir, dan praktek pembibitan mangrove dari jenis Rhizophora sp. Media tanam yang digunakan adalah tanah yang berasal dari lokasi pembibitan yang dikemas kedalam kantong polybag tanpa menggunakan tambahan pupuk organik maupun anorganik. Propagul mangrove disemai dengan cara ditancapkan kedalam polybag yang telah berisi media tanah dengan kedalaman ± 15 cm. Seluruh rangkaian kegiatan tersebut dilakukan oleh siswa sekolah yang berjumlah 30 orang. Hasil kegiatan pengabdian ini menujukkan bahwa propagul mangrove yang disemai tumbuh dengan baik. Setelah ± 30 hari setelah penyemaian, propagul yang disemai telah memunculkan dua helai daun muda yang menandakan bahwa sistem perakaran mulai terbentuk. Hal ini menegaskan bahwa pelibatan generasi muda khususnya siwa sekolah cukup efektif dalam upaya rektorasi ekosistem pesisir , khususnya ekosistem mangrove.
