Kelimpahan fitoplankton menunjukkan tingkat produktivitas perairan. Dalam upaya pemanfaatan sumberdaya hayati estuari Sungai Siak, diperlukan kajian kondisi komunitas dan kelimpahan fitoplankton serta hubungannya dengan kondisi oseanografi yang menggambarkan produktivitas perairannya. Untuk itu, telah dilakukan penelitian mengenai hubungan antara kelimpahan dan sebaran spasial-temporal fitoplankton dengan parameter oseanografi di estuari Sungai Siak. Penelitian ini dilakukan secara in-situ di 16 titik sampling pada April, Mei, Juni, Agustus, September, Oktober dan November 2015. Hasil penelitian menemukan 54 genera dari 3 kelas yaitu Chyanophyceae, Dinophyceae dan Bacilliriophycaea. Kelas Bacilliriophycaea merupakan yang dominan (85%) dengan jenis yang terbanyak dan selalu ditemukan di setiap stasiun adalah Chaetoceros dan Rhizosolenia. Kelimpahan fitoplankton tergolong sedang, dengan kelimpahan tertinggi pada Juni dan Oktober serta terendah April. Indeks keanekaragaman (H?) dan indeks keseragaman (E) tergolong tinggi masing-masing 4,39-5,46 dan 0,83-0,94, sementara indeks dominansi (D) termasuk kategori rendah (0,03-0,16). Indeks komunitas ini menunjukkan fitoplankton di perairan ini keanekaragaman dan kestabilan komunitasnya sedang dan tidak ada spesies yang mendominasi. Uji korelasi menunjukkan terdapat keterkaitan yang erat antara kelimpahan dengan Oksigen (0,667); salinitas (0,663), kecerahan (0,628); pH (0,472); arus (0,283); dan suhu (0,046). Komponen utama oseanografi perairan ini mempengaruhi secara signifikan (75%) dengan selang kepercayaan 95%. Meskipun tingkat kecerahan perairan dan kandungan Oksigen terlarut tergolong rendah, namun parameter oseanografi lainnya seperti suhu, salinitas dan pH masih berada pada kisaran yang masih dapat mendukung kehidupan fitoplankton di estuari Sungai Siak.

The high demand for shrimp commodities will increase catching to spur production so that it will affect the shrimp population. This scientific study will discuss the spawning season of banana shrimp (Penaeus merguiensis), catch size, and environmental conditions of Dumai and surrounding waters. This research was conducted from April to December 2018 using survey methods around the waters of Dumai, Riau. Data collection was carried out monthly on 4,677 banana shrimps assisted by enumerators. The analysis was carried out on the relationship between carapace length and body weight, sex ratio, gonad maturity level, and catch size. The condition of the aquatic environment that influences the process of reproduction becomes a comparison in determining management efforts. Banana shrimp size structure 18-60 mm, dominant at 28 mm and negative allometric growth patterns. The genital ratio shows that female shrimp are more dominant than males and the spawning season lasts throughout the year with peaks in June and December. The length at first capture was 34.5 mm with the length at first maturity was 30.8 mm (Lc> Lm), meaning that it had spawned before being capture. However, the polluted water environment can interfere with the process of growth and population growth even though various environmental parameters are still within normal limits. So the thing to do is to close the shrimp catching area in June and December, not catch in the spawning area, the size of the shrimp that can be caught is 31 mm and protect the aquatic environment from pollution.

Tingginya permintaan pasar terhadap udang dogol (Metapenaeus ensis de Haan) telah mengakibatkan tingginya intensitas penangkapan yang jika berlangsung secara terus-menerus akan mengancam kelestariannya. Penelitian tentang status stok merupakan salah satu dasar utama dalam merumuskan pengelolaan menuju pemanfaatannya secara berkelanjutan. Tujuan penelitian ini adalah untuk mengetahui status stok udang dogol di perairan Bombana dan sekitarnya, Sulawesi Tenggara. Penelitian dilakukan dari bulan April sampai dengan Nopember 2021 dengan metode survey. Hasil penelitian menunjukkan bahwa alat tangkap yang digunakan untuk mengusahakan udang dogol adalah pukat dasar (mini trawl) dengan komposisi hasil tangkapannya didominasi udang dogol (M. ensis de Haan) sekitar 26 %. Pola pertumbuhan udang dogol di perairan Bombana dan sekitarnya bersifat allometrik negatif serta perbandingan kelamin jantan dan betina berada dalam keaadan tidak seimbang. Ukuran rata-rata pertama kali tertangkap (Lc) adalah pada panjang karapas 29,8 mm dan ukuran rata-rata pertama kali matang kelamin (Lm) udang dogol adalah pada panjang karapas 31,7 mm. Laju pertumbuhan (K) udang dogol sebagai 1,0 per tahun dan panjang total maksimum (Loo) sebagai 46,2 mm. Laju kematian total (Z) udang dogol sebagai 4,42, per tahun, laju kematian karena penangkapan (F) dan laju kematian alami (M) masing-masing 1.58 per tahun dan 2, 84 per tahun. Tingkat pemanfaatan (E) udang dogol adalah 0,36 (72 %) per tahun, dengan demikian status stok udang dogol belum berada pada penangkapan berlebih (overfishing). Agar sumber daya udang masih tetap terjamin kelestariannya, maka masih bisa dilakukan penambahan upaya sekitar 28 % dari jumlah upaya saat ini.The high market demand for Endeavour shrimp (Metapenaeus ensis de Haan) has resulted in high fishing intensity, which, if it continues, will endanger the species' sustainability. Studies of stock status are important for formulating a management for sustainable utilization. The purpose of this study was to determine the stock status of endeavour shrimp in the Bombana and and its surrounding waters. The study was conducted from April to November 2021 using a survey method. The study results revealed that the endeavor shrmp growth pattern in Bombana watwas negative allometric and that the ratio of males and females was unbalanced. The length at first capture (Lc) was 24,9 mm (carapace length) and the length at first maturity (Lm) was at a total carapace length of 31,7 mm. The growth rate (K) as 1,0 per year and the carapace length maximum (L∞) was 46.a mm. The estimate total mortality rate (Z) was 2.51 per year, the fishing mortality rate (F) and natural mortality rate (M) were 0.91 per year and 1.61 per year, respectively. The exploitation rate (E) was 0.36 (72 %) per year, therefore that the stock status isn’t overfishing. In order to ensure the sustainability of the endeavour shrimp, there are still opportunities for increasing effort about 28 % from the current situation.

DNA extraction is a fundamental initial step in numerous molecular research studies. Different extraction methods are required for different biological samples to obtain high-quality DNA. Therefore, this step is one of the limiting factors for the success of molecular analysis. There has been no research evaluating an appropriate method to extract DNA from ambergris jetsam samples. This study aims to determine an appropriate method for extracting DNA from whale ambergris samples. The ambergris sample was collected from the southern coast of Cilacap. DNA extraction was performed using a commercial DNA isolation kit and the Chelex® 100 method. The extracted DNA was visualized using agarose gel electrophoresis followed by quantification with a UV Nanodrop spectrophotometer. The data were analyzed descriptively to determine the most effective extraction method. The success of the extraction was also assessed by measuring the DNA concentration using the Nanodrop spectrophotometer. The results showed that the commercial isolation kit failed to produce genomic DNA from whale ambergris, as indicated by the absence of stained DNA bands on the agarose gel. In contrast, the Chelex® 100 method successfully produced genomic DNA from ambergris, as evidenced by the presence of stained DNA bands on the agarose gel and a high quantity of genomic DNA after a Nanodrop measurement. It can be concluded that the Chelex® 100 method is more suitable than commercial kits for extracting DNA from ambergris samples. This finding contributes to the development of various scientific fields based on molecular data by providing evidence that each biological sample requires an appropriate method to obtain high-quality DNA.

Pelagic fish are spesies that live in water column at depth of 100 to 200 meters from surface. They migrate as a group looking for nutrient and spawning place. Potential fisheries comodities in Indonesia including pelagic fish have high economic value. Then, stock assessment of pelagic fish measurement is important to researched. The research was conducted in May – June 2016 surrounding South China Sea waters using Madidihang 02 Research Vessel operated by Marine Fisheries Affair (MFA) Republic of Indonesia. To estimate the density of pelagic fish hydro-accoustic equipment and oceanography parameters were used and measured during the campaign. The split beam echosounder was use in aim to obtain precission position and number of fish target. The highest density of fish was found around Tambelan Island and Anambas Island. Statistically pelagic fish density has correlation with chlorophyll-a, salinity, temperature, and sea current velocity. The statistical analysis between pelagic fish density and those oceanography parameters (as statistic variables) yields positive vector correlation.

Lobster adalah komoditas bernilai tinggi yang di perdagangkan hingga ke mancanegara, bahkan dalam kondisi puerulus. Tingginya permintaan ini memacu peningkatan pemanfaatan sehingga diperlukan upaya untuk menjaga kelestarian populasinya. Kajian ini membahas tentang aspek biologi dan status pemanfaatan yang diharapkan menjadi dasar dalam pengelolaan lobster bambu (Panulirus versicolor) sehingga kelestarian dapat berkelanjutan. Pengumpulan data dilakukan Maret sampai dengan Desember 2020, diperoleh sampel sebanyak 2.040 ekor melalui sentra pendaratan ikan di Dobo, Kepulauan Aru. Penghitungan parameter populasi dilakukan melalui analisis secara analitik. Hasil penelitian diperoleh kisaran panjang karapas antara 45-120 mm, sebanyak 40% diantaranya mempunyai ukuran kurang dari 80 mm. Panjang karapas pertama kali lobster tertangkap (CLc) adalah 85,4 mm dengan panjang asimptotiknya (CL∞) adalah 130,85 mm dan laju pertumbuhan (K) = 0,45 per tahun. Tingkat pemanfaatan lobster sudah mencapai E=0,5, artinya sudah dalam status pemanfaatan penuh (fully exploited). Hal ini menyebabkan pemanfaatan lobster harus dilakukan dengan kehati-hatian dan perlu upaya dalam menjaga kelestariannya. Upaya-upaya yang dapat dilakukan mengendalikan penangkapan baik dari segi alat tangkap, waktu dan lokasi penangkapan. Upaya tersebut diharapkan akan memberikan kesempatan bagi lobster untuk mempertahankan kelestarian populasinya. Lobster is a high-value commodity traded to foreign countries, even their puerile. As the high demand for lobsters increases their exploitation, special measures are imperative to preserve their populations. This study discussed the biological aspects and exploitation status, which are expected to be the basis for managing painted spiny lobster (Panulirus versicolor). Data collection was carried out from March to December 2020, which is 2,040 lobsters collected at the landing center at Dobo, Aru Islands. Analytical methods were used to analyze population parameters. The results showed that the carapace length of lobsters landed was between 45–120 mm, where 40% of them were under 80 mm. Their size at first capture (CLc) was 85.4 mmCL, with asymptotic length (CL∞) was 130.85 mmCL and growth rate (K) was 0.45 per year. Their exploitation rate was E was 0.5 (fully exploited exploitation). Therefore, its exploitation has to be carried out with caution, and special measures are required to maintain its sustainability, i.e., by controlling lobster fishing efforts, including fishing gear, time, and location. Such actions are expected to allow lobsters to preserve the sustainability of their populations.

Kepiting bakau merupakan komoditas ekspor yang penangkapannya dilakukan dengan intensif, salah satunya adalah jenis kepiting merah (Scylla olivacea). Pengelolaan dalam pengendalian memerlukan analisa kajian ilmiah tentang ukuran layak tangkap dan spawning potential ratio (SPR) kepiting merah. Kajian ilmiah ini dilakukan terhadap 1.105 ekor kepiting merah di pusat pendaratan kepiting di Desa Silo Baru Kecamatan Silau Laut Kabupaten Asahan, Sumatera Utara selama 28 bulan (April-Oktober 2018, Februari- Desember 2019 dan Maret-Desember 2020). Kepiting yang tertangkap memiliki ukuran 65-170 mm dengan 72,2% sudah dewasa dan telah melakukan pemijahan sebelum tertangkap (CWc< CWm). Hasil penelitian diperoleh bahwa kematian akibat penangkapan (F) lebih tinggi dibandingkan kematian alamiah (M), hal ini menunjukkan tingginya tekanan pemanfaatan (E = 0,54%). Nilai spawning potential ratio (SPR) mengalami peningkatan dari tahun 2018 ke tahun 2020 yaitu 11-17% namun masih dibawah nilai minimal 20%, artinya penambahan individu kepiting merah di perairan Asahan setelah ekspolitasi sudah mengalami penurunan sehingga diperlukan upaya dalam pengelolaan. Upaya yang dapat dilakukan adalah dengan meningkatkan ukuran mesh size jaring dan bubu serta rehabilitasi hutan mangrove.Mud crabs are export commodities that have been harvested intensively; one of which is the red mud crab (Scylla olivacea). Management in controlling its exploitation requires scientific studies on the analysis of the legal size and the potential spawning ratio (SPR) of the crab. In this scientific study, a total of 1,105 red mud crabs were analyzed at the crab landing center in Silo Baru Village, Silau Laut District, Asahan Regency, North Sumatra for 28 months (April–October 2018, February–December 2019, and March–December 2020). The crabs caught were 65–170 mm in size, where 72.2% of which were already adults and had spawned before being caught (CWc < CWm). The results of this study suggested that the fishing mortality (F) was higher than the natural mortality (M), indicating a high exploitation (E = 0.54%). On the other hand, the potential spawning ratio (SPR) from 2018 to 2020 kept increasing, i.e. 11–17% (below the minimum SPR 20%), indicating that the addition of the individual red mud crabs in Asahan waters after exploitation had decreased. Therefore, several efforts are necessary in its management, among others by increasing the mesh size of the nets and the size of the traps as well as rehabilitating mangrove forests.
