Lobster batu (Panulirus penicillatus) merupakan salah satu sumberdaya perikanan yang ada di Teluk Palabuhanratu. Informasi mengenai dinamika populasi lobster batu masih minim. Penelitian ini bertujuan menganalisis tingkat pemanfaatan lobster batu (Panulirus penicillatus) di Teluk Palabuhanratu, serta membandingkan ukuran saat pertama kali tertangkap (Lc50) terhadap ukuran lobster batu betina saat pertama kali mengerami telur (Lr50). Penelitian dilaksanakan pada Oktober 2016 hingga Maret 2017. Estimasi parameter populasi menggunakan FiSAT II. Pendugaan Lc50 dan Lr50 menggunakan metode kurva logistik. Lobster yang tertangkap memiliki ukuran 40–102 mm panjang karapas, serta umur maksimum jantan dan betina yaitu 8,0 dan 7,0 tahun. Puncak rekrutmen terjadi pada Agustus hingga September. Laju eksploitasi lebih dari 0,50. Lobster jantan dan betina memiliki Lc50 62,5 mm dan 61,0 mm. Nilai Lr50 betina adalah 65,3 mm. Sumberdaya lobster batu di Teluk Palabuhanratu terindikasi sudah mulai tangkap lebih, dan lobster batu betina sudah tertangkap sebelum mencapai ukuran rata-rata mengerami telur.

Rajungan (Portunus pelagicus) merupakan salah satu sumberdaya perikanan yang memiliki wilayah persebaran yang beragam di Indonesia, salah satunya adalah Laut Jawa. Wilayah persebaran yang beragam menyebabkan kondisi lingkungan yang berbeda, sehingga diduga dapat menimbulkan keragaman morfometrik. Tujuan dari penelitian ini adalah menganalisis keragaman morfometrik P. pelagicus di WPP 712 untuk menggambarkan kondisi unit stok rajungan di wilayah tersebut. Lokasi pengambilan contoh berada di Pulau Lancang, Cirebon, dan Madura. Pengukuran karakter morfometrik rajungan dilakukan dengan metode baku. Hasil yang didapat pada analisis Kruskall-Wallis terdapat 4 karakter pembeda pada metode baku. Analisis kluster memperlihatkan bahwa P. pelagicus di Pulau Lancang dan Cirebon membentuk kelompok yang sama, sedangkan P. pelagicus di Madura membentuk kelompok yang terpisah. Analisis diskriminan menunjukkan terdapat tiga populasi P. pelagicus, yaitu populasi Pulau Lancang, Cirebon, dan Madura. Berdasarkan hasil yang didapat P. pelagicus yang berada di WPP 712 memiliki potensi lebih dari satu unit stok.

Mole crabs live in intertidal areas of sandy beaches. Identification of aquatic species is often due misidentification cause by the cryptic phenomenon, so it is needed identification technique with a molecular approach by DNA barcoding. The study was purposed to validity and analyze kinship of the mole crabs based on 16S rRNA molecular marker from Bantul and Purworejo waters. Commercial kit of Gene Aid was used to isolation and extraction of DNA and was produced three total DNA from each location. DNA total with good quality was continued to amplified process using PCR technique with a primer of 16S rRNA. Sequence products of 16S rRNA gene were aligned with several sequences of species other from genus Emerita, Scylla, and Portunus that was found from GenBank. Species validation was performed using BLASTn. Genetic distance and phylogenetic tree were obtained MEGA 5.0 program. The samples of mole crab from Bantul and Purworejo were insignificantly different and the samples were from the same genetic sources.

The hammerhead shark has high economic value, but its population is highly threatened due to its high exploitation. This study aims to calculate the level of preference of shark fishermen on the value of willingness to pay for the conservation of hammerhead shark resources. This research was conducted from November to December 2020 in Tanjung Luar Village, East Lombok Regency. The method used is observation and in-depth interviews with a sample of 150 shark fishermen. The analysis used is binary logit regression analysis using the R studio 4.1.2 tool. The results of this study indicate that (1) the total price of willingness to pay from all Tanjung Luar shark fishermen is IDR 9,654,000, and the average monthly value is IDR 53,633 per person; (2) factors that are quite influential on respondents' willingness to pay are age, education level, number of family members, and monthly income. The conservation of hammerhead shark resources needs to be considered because it has been included in the CITES Appendix II red list with a critically endangered status towards extinction. Suggestion there is a need for educational steps from various parties to fishermen regarding the importance of the existence of hammerhead sharks in the ecosystem so that they can reduce the high level of fishing activity in nature.

People use fish to meet their needs. Fish utilization and economic activities in the neritic tuna’s fishery system at Pasongsongan were an effort to achieve social welfare. However, the uncertainty surrounding economic activities caused a risk to fishermen's income stability. Those are conducted in this research to identify the elements of social-ecological system of neritic tuna fisheries at Pasongsongan and to assess the risk based on the uncertainty of the daily fish prices. Identification of the elements of the social-ecological system followed the framework by Ostrom, while the uncertainty was analyzed by monte carlo simulation using R-Studio. The results showed six elements of Resource System, three elements of Resource Units, one element of the Governance System, and three elements of Resource Actors. The interaction between elements is fishing productivity and information exchange. The montecarlo simulation showed the fish price determination method contains uncertainty with a greater risk in the daily fish price of kawakawa or komo (Euthynnus affinis) compared to frigate tuna (Auxis thazard), with standard deviation values respectively IDR 8.255 and IDR 6.251. Fish measurement cause the uncertainty of daily fish prices without using validated measuring; therefore, fish weight measurement infrastructure needs to increase pricing considerations accuracy objectively.

Ikan tongkol komo (Euthynnus affinis) merupakan salah satu komoditas ekonomis penting yang tertangkap di perairan Laut Jawa sebelah utara Jawa Timur. Tingkat pemanfaatan ikan tongkol komo terus meningkat sehingga perlu dikelola dengan baik untuk keberlanjutannya agar tidak mengalami penurunan stok. Tujuan penelitian ini untuk mengevaluasi status sumberdaya ikan tongkol komo dengan mengestimasi parameter populasi dan rasio potensi pemijahan dengan pendekatan ukuran panjang ikan, digunakan sebagai titik acuan biologis dalam menentukan kondisi stok ikan. Sebanyak 1995 data ukuran panjang ikan yang dikumpulkan secara acak selama bulan Februari hingga Juni 2021 di Pasongsongan, Jawa Timur. Metode ELEFAN digunakan untuk menentukan parameter populasi yaitu pertumbuhan, kematian, dan laju pemanfaatan. Analisis rasio potensi pemijahan dilakukan dengan menggunakan parameter populasi, dan parameter biologi yang didapatkan dari hasil penelitian sebelummnya dengan paket LB-SPR. Hasil analisis pertumbuhan von Bertalanffy ikan tongkol komo dari penelitian ini diperoleh persamaan Lt= 60,9 (1-e-0,41(t-0,19)). Rata-rata tongkol komo yang tertangkap belum matang gonad (Lc<Lm), tekanan penangkapan dalam kategori tinggi dan rekrutmen dalam stok terganggu. Hal ini terlihat bahwa rasio mortalitas penangkapan relatif (F/M) = 2,51, laju eksploitasi (E) = 0,71, dan SPR = 20%. Oleh sebab itu diperlukan penyusunan pengelolaan yang efektif untuk keberlanjutan stok ikan tongkol komo.Kawakawa (Euthynnus affinis) is one of the important economic commodities caught in the sea waters north of East Java. The utilization rate of kawakawa is quite high, so it is necessary to regulate the sustainability of kawakawa stock to maintain it. This study aimed to evaluate the status of kawakawa fish resources by estimating population parameters and spawning potential ratio (SPR) with a fish length approach, used as a biological reference point in determining fish stock conditions. 1995 data on the length of fish were collected randomly from February to June 2021 in Pasongsongan, East Java. The ELEFFAN method was used to determine population parameters: growth, mortality, and utilization rate. SPR analysis was carried out using population and biological parameters obtained from previous studies with the LB-SPR package. The results of von Bertalanffy's growth analysis for kawakawa from this study were written with the equation Lt= 60.9 (1-e-0.41(t-0.19)). The average kawakawa caught was immature gonads (Lc<Lm), fishing pressure was also still high, and recruitment in stock was disrupted. It can be seen that the relative fishing mortality ratio (F/M) = 2.51, exploitation rate (E) = 0.71, and SPR = 20%. Therefore, it is necessary to develop effective management for the sustainability of kawakawa stocks.

The increasing Blue swimming crab/BSC fishing activity is a response to the high demand of the international market. One of the potential coastal waters for BSC capture fisheries is Pati Regency. However, biological information related to BSC resources is still limited in this area. Therefore, the purpose of this study is to analyze the characteristics of BSC fishing and the size structure of the caught BSC. The study was conducted from December 2020 to March 2021. The method of data collection is observation and interview with fishermen, while the analysis is carried out descriptively. The location of BSC fishing is divided into 3 zones. The characteristics of BSC fishing locations include those related to the distance from the coastline, technical aspects and types of fishing gear, as well as the operational system of capture. The distance from the coastline in zone 1 is about 1-2 miles, zone 2 is about 2-3 miles, and zone 3 is more than 3 miles. The types of fishing gear used in zone 1 are bottom gill net, zone 2 and zone 3 are trapnet. The operational system of capture in zone 1 and zone 2 is carried out with daily trips, while in zone 3 it is carried out with weekly trips (babang). The distribution of carapace width sizes in zone 1 ranges from 44.00-139.00 mm (average 104.80±11.00 mm), in zone 2 it ranges from 72.10-138.00 mm (average 107.90±12.30 mm), and in zone 3 it ranges from 101.40-177.60 mm (average 126.50±11.50 mm).

The Medan Sea waters are part of the Indonesian Fisheries Management Area (WPPRI 571) and serve as a fishing ground for squid (Uroteuthis spp.) for small-scale fishers based in Belawan, Medan. Information on the condition of the squid fishery in this area is limited, so a scientific study is needed to determine the status of the fishery as a basis for determining the right management approach. This study aims to assess the current condition of the squid fishery in Belawan using the six domains of indicators in the Ecosystem Approach to Fisheries Management (EAFM): fish resources, habitat, and ecosystem, fishing techniques, economic, social, and institutional. Data were collected through various techniques including direct sampling of squid, in-depth interviews, questionnaires, and secondary data collection. The results showed that the highest value was owned by the fishing technique domain at 280 (good category) and the lowest domain fish resource domain with 168 as a poor category. The low score was due to a decrease in catches and a change in the fishing location. Meanwhile, the aggregate calculation results show that all domains of the Belawan-Medan EAFM are 195 (medium category). This means that some tactical decisions are needed in squid fisheries management in this region. Keywords: EAFM, Medan waters, Small scale fishery, Squid, WPP 571.

Lobster batu (Panulirus penicillatus) merupakan salah satu komoditas ekonomis penting yang tertangkap di perairan Kabupaten Kaur Provinsi Bengkulu. Permintaan pasar yang tinggi mengakibatkan aktivitas penangkapan yang terus menerus dapat mengancam kelestarian sumberdaya lobster maka dari itu perlu dikelola dengan baik dalam menjaga keberlanjutan stok Tujuan penelitian ini untuk menganalisis status stok sumberdaya lobster batu dengan mengestimasi parameter populasi dan rasio potensi pemijahan berdasarkan pendekatan ukuran panjang karapas lobster yang kemudian digunakan sebagai titik acuan biologis untuk menentukan kondisi stok lobster. Pengumpulan sebanyak 707 sampel yang diambil secara acak dilakukan sejak bulan November 2022-Februari 2023 di Kecamatan Nasal, Kabupaten Kaur, Bengkulu. Data yang dikumpulkan meliputi panjang karapas dan bobot, parameter populasi, berupa pertumbuhan, kematian, dan laju pemanfaatan dianalisis menggunakan metode ELEFAN dalam bahasa program R. Analisis spawning potential ratio (SPR) dihitung berdasarkan parameter populasi dan parameter biologi paket LB-SPR. Hasil analisis pertumbuhan von Bertalanffy lobster batu diperoleh persamaan Lt = 133,28(1-e-0,53(t-0,23)). Rata-rata lobster batu yang tertangkap belum mengalami fase dewasa kelamin (Lc<Lm), mengartikan bahwa tekanan penangkapan dalam kategori tinggi dan rekrutmen dalam stok terganggu. Hal ini terlihat bahwa rasio mortalitas penangkapan relatif (F/M) adalah 2,79, laju eksploitasi (E) adalah 0,736, dan SPR senilai 9%. Hal ini menunjukkan bahwa status stok lobster sudah berada pada penangkapan berlebih (overexploited). Oleh karena itu perlu adanya pengelolaan yang efektif untuk keberlanjutan stok lobster batu.

Ikan semar (Mene maculata) merupakan ikan demersal yang memiliki nilai ekologi dan ekonomi penting. Tingginya pemanfaatan kantong semar sebagai ikan konsumsi berpotensi mengganggu pola reproduksi, rekrutmen dan ketersediaan stok sumber daya ikan kantong semar, sehingga informasi mengenai biologi reproduksi sangat minim pada musim barat. Penelitian ini bertujuan untuk menganalisis status biologi reproduksi ikan semar di Teluk Palabuhanratu. Penelitian berlangsung pada bulan September 2021 sampai dengan bulan Februari 2022 (mewakili musim barat), dengan sampel sebanyak 522 individu ikan. Sampel ikan diambil dengan menggunakan metode simple random sampling di Pelabuhan Perikanan Nusantara Palabuhanratu. Data tersebut dianalisis untuk memperoleh nisbah kelamin, pola pertumbuhan alometrik, musim pemijahan, potensi reproduksi, dan ukuran dewasa kelamin. Hasil penelitian menunjukkan bahwa rasio kelamin adalah 1:0,76 yang didominasi oleh ikan jantan. Ikan semar memiliki pola pertumbuhan alometrik negatif. Puncak musim pemijahan pada periode penelitian terjadi pada bulan September dan Oktober dengan potensi reproduksi berkisar antara 11.988 hingga 21.164 butir telur. Pola pemijahan ikan semar terindikasi sebagai pemijahan total atau pemijahan yang terjadi secara serentak. Hasil analisis dengan metode Spearman-Karber menunjukkan bahwa ukuran pertama ikan semar betina dan jantan (Lm50) matang kelamin masing-masing adalah dengan panjang total (TL) 143 mm dan 150,5 mm, sehingga ikan betina lebih cepat dahulu matang kelamin dibanding ikan jantan.
