Pesisir Desa Kramat merupakan bagian dari sebaran mangrove di kawasan Teluk Tomini. Tekanan lingkungan akibat aktivitas masyarakat seperti alih fungsi kawasan dan sampah pesisir ditengarai telah merusak kawasan mangrove di Desa Kramat. Kondisi tersebut dikhawatirkan berdampak pada gastropoda sebagai komponen esensial ekosistem mangrove. Penelitian ini bertujuan untuk mengamati kekayaan jenis, keanekaragaman dan kelimpahan gastropoda mangrove di pesisir Desa Kramat, Kabupaten Boalemo, Provinsi Gorontalo. Penelitian dilakukan dengan cara mensurvei populasi gastropoda menggunakan kuadran berukuran 5x5 m yang dibuat pada tiga transek garis (LT) yang berbeda berdasarkan lebar sabuk mangrove. Hasil penelitian menunjukkan bahwa jumlah spesies gastropoda di ekosistem mangrove adalah 14 yang mewakili anggota 8 famili. Kelimpahan tertinggi terdapat di LT-1 dengan lebar sabuk mangrove terkecil, yaitu Terebralia sulcata (14.800 ind/ha) untuk tingkat spesies dan Potamididae (20.600 ind/ha) untuk tingkat famili. Nilai indeks keanekaragaman Shannon-Wiener untuk semua spesies berkisar antara 1,517 hingga 2,177. Nilai indeks dispersi Morisita berkisar antara 0,97–14,00 untuk tingkat spesies dan 0,97–4,67 untuk tingkat famili. Meskipun jumlah spesies gastropoda cukup besar, nilai indeks keanekaragamannya tergolong sedang, dengan sebaran mengelompok. Kajian ini menunjukkan peran ekologis kawasan mangrove Desa Kramat sebagai penunjang keanekaragaman hayati dan habitat gastropoda yang diperlukan untuk pengelolaan kawasan pesisir di Teluk Tomini. The coast of Kramat Village is part of the mangrove distribution area in the Tomini Bay area. Environmental pressures due to community activities such as area conversion and coastal waste are suspected of degrading the mangrove area in Kramat Village. The condition is feared to impact gastropods as an essential component of the mangrove ecosystem. This research aimed to observe species richness, diversity, and the abundance of mangrove gastropods on the coast of Kramat Village, Boalemo Regency, Gorontalo Province. The study was conducted by surveying the gastropod population using a 5x5 m quadrant established on three different line transects (LT) based on the width of the mangrove belt. The study's results showed that the number of gastropod species in the mangrove ecosystem was 14, representing members of 8 families. The highest abundance was found in LT-1 with the smallest mangrove belt width, namely Terebralia sulcata (14,800 ind.ha-1) for species level and Potamididae (20,600 ind.ha-1) for family level. The Shannon-Wiener diversity index values for all species ranged from 1.517 to 2.177. Morisita's dispersion index values ranged from 0.97-14.00 for the species level and 0.97-4.67 for the family level. Although the number of gastropod species is quite large, the diversity index value is categorized as a medium, with distribution clumped. This study shows the ecological role of the mangrove area of Kramat Village to support biodiversity and as a habitat for gastropods needed for the management of coastal areas in Tomini Bay.

Highlight ResearchThe fishing area of S. leptolepis in this study was confirmed to be located in Tomini BayThe fish samples were gathered randomly from fishers' catch using purse seinesThe growth curve for the male and female fish data were both plotted following the trend of the Von Bertalanffy equationThis study estimates the growth parameters, mortality, and exploitation rates of the male and female fish separately.AbstractComprehensive data is required for implementing sustainable fisheries management. Population dynamic and stock assessment aspects of Selaroides leptolepis species in Tomini Bay have not been entirely reported. This study aimed to determine the fishing mortality rate and exploitation status of S. leptolepis in Tomini Bay by calculating Von Bertalanffy growth model parameters (Lâˆž, K, t0) then plotting them into Pauly's empirical equation. The sampling was conducted monthly from April to September 2020 at Gorontalo City Fishing Port. Samples were collected randomly from five commercial fishing vessels shortly after the fishermen landed their catch at the fishing port. All fish samples were confirmed to be obtained by the fishermen from Tomini waters. The growth parameters of the samples were analyzed using FiSAT II based on Von Bertalanffy mathematical model. While the mortality and exploitation values were calculated manually using Pauly's equation. The study showed that the growth parameter values of S. leptolepis in Tomini Bay were 245.47 mm, 0.49/year, and -3.04/year for males, while 227.80 mm, 0.63/year, and -2.72/year for females separately for Lâˆž, K, and t0. The total, natural, and fishing mortality rates were 3.06/year, 0.61/year, and 2.45/year for males and 0.99/year, 0.74/year, and 0.25/year for females. The analysis results showed that the female's natural mortality (M) was higher than the male. In contrast, the fishing mortality (F) and total mortality (Z) of male fish exceed the female. The exploitation value of males (E=0.80) was greater than that of females (E=0.26).

Selar termasuk komoditas ikan laut yang bernilai ekonomis karena permintaan pasar yang tinggi dan didukung oleh ketersediaan populasi di alam sepanjang tahun. Truss morfometrik ikan merupakan salah satu karakter terukur yang umum diterapkan dalam studi morfologi ikan sebagai potensi pembeda seksual ikan pada spesies tertentu. Tujuan penelitian ini adalah menyajikan informasi mengenai morfologi, menentukan rasio truss morfometrik terhadap panjang tubuh total yang dapat dijadikan karakter pembeda seksual, serta membandingkan pola pertumbuhan Selar crumenophthalmus jantan dan betina. Jumlah sampel sebanyak 100 ekor dikumpulkan secara random di Tempat Pendaratan Ikan Tenda Kota Gorontalo selama dua hari penangkapan pada bulan Juni 2022. Hasil pengamatan morfologi menunjukkan bahwa bentuk tubuh S. crumenophthalmus adalah kompres dengan tipe sisik sikloid. Bagian dorsal tubuh berwarna biru gelap kehijauan, bagian ventral berwarna silver cenderung putih, terdapat area tipis berwarna kuning membujur dari batas operkulum sampai batang ekor pada sisi lateral tubuh yang terletak di atas linea lateralis, sirip kaudal berbentuk cagak dan simetris, memiliki rumus sirip DIX, 24-27 dan AIII, 21-23. Terdapat 14 truss morfometrik yang dapat dijadikan sebagai ciri pembeda S. crumenopthalmus jantan dan betina yaitu 1 karakter pada bagian kepala (A4), 6 karakter pada tubuh bagian anterior (B1, B2, B4, B5, B6, B9), 3 karakter pada tubuh bagian posterior (C2, C5, C6), dan 4 karakter pada bagian ekor (D1, D2, D3, D5). Adapun pola pertumbuhan spesies jantan dan betina pada sampel riset ini sama-sama bersifat allometrik positif. Selar is a marine fish commodity that has economic value due to high market demand and is supported by the availability of natural populations throughout the year. Fish morphometric truss is one of the measurable characteristics that is commonly applied in the study of fish morphology as a potential sexual differentiation of fish in certain species. The aim of this research is to present information regarding morphology, determine the ratio of morphometric truss to total body length which can be used as a sexual distinguishing character, and compare the growth patterns of male and female Selar crumenophthalmus. A total of 100 samples were collected randomly at the Gorontalo City Tent Fish Landing Site during two days of fishing in June 2022. The results of morphological observations showed that the body shape of S. crumenophthalmus was compressed with cycloid scale type. The dorsal part of the body is dark greenish blue, the ventral part is silver, and tends to be white, and there is a thin yellow area stretching from the border of the operculum to the caudal peduncle on the lateral side of the body which is located above the linea lateralis, the caudal fin is forked and symmetrical, has the fin formula DIX, 24-27 and AIII, 21-23. There are 14 morphometric trusses that can be used as distinguishing characteristics of male and female S. crumenopthalmus, namely 1 character on the head (A4), 6 characters on the anterior body (B1, B2, B4, B5, B6, B9), 3 characters on the body the posterior (C2, C5, C6), and 4 characters in the tail (D1, D2, D3, D5). The growth patterns of male and female species in this research sample were both positive allometric.

This study presents a comprehensive checklist of sea cucumber species found in Biluhu Timur waters, Tomini Bay, Gorontalo, Indonesia, across the new moon and full moon lunar phases. The survey identified eight species across five genera, including Actinopyga miliaris, A. mauritiana, Holothuria scabra, and H. leucospilota, noting significant distribution patterns influenced by lunar cycles and different biomes at three stations. Actinopyga miliaris and A. mauritiana, both classified as Vulnerable, were more active in the seagrass biome of Station I during the full moon. H. leucospilota, classified as Least Concern, was highly prevalent in the sandy substrate biome of Station II during the new moon, indicating a strong ecological association with that habitat. Stichopus horrens, classified as Data Deficient, showed notable activity in the coral reef biome of Station III. Environmental parameters such as water temperature, salinity, and pH were measured at each station to understand the conditions influencing these species. This study highlights the importance of lunar phases, biomes, and environmental variables on sea cucumber distribution. The findings underscore the need for conservation efforts that consider these factors to protect species vulnerable to overfishing and habitat degradation. Further research should include genetic analysis and expanded temporal and spatial scales to develop effective conservation strategies and sustainable management practices
