Caroun croaker (Johnius carouna) is one of demersal fishes which are commonly caught in the south of Java waters. This fish captured by trammel net, gillnet, danish seine and mini trawl. This study aims to determine length and weight relationship, growth parameter, length frequency distribution and condition factors of croaker fish caught in the south of Java waters.   This study was conducted from January-December 2015 at the Cilacap Ocean Fisheries Port, Central Java. Data collected was total length (TL in mm) and weight (W in g) of caroun croacker fish.  A total of 2141 of Caroun croaker was caught by mini trawl during the sampling periods. The result showed that the size of croaker fish caught by mini trawl ranged between 85-225 mm with an average was 143.7 mm. Length and weight relationship expressed by equation of W = 0.0062 TL3.2889 ( R2 = 0.9443). The growth pattern of croaker fish was allometric positive. The Von Bertalanffy growth equation of caroun croacker fish in south of Java waters was Lt =155 (1 - e -0.9(t+0.2127)) with the asymptotic length (L∞) =155  mm, growth coefficient (K) = 0.9 per year and the theoretical age croaker fish that was equal to (t0) = - 0,2127.

Giant catfish (Arius thalassinus) is one of demersal fish that has important economic potential. In the Cilacap waters, this fish caught by gillnet. Study of giant catfish is still limited. The objective of this study was to obtain the growth pattern and factor condition for giant fish in the Cilacap waters. This study was conducted from January to December 2015 in the Ocean Fishing Port of Cilacap, Central Java. A total number of 1126 individual of Arius thalassinus caught by gillnet was observed during the sampling periods. Total length and weight those fishes were analyzed. The result showed that the size ofgiant catfish caught by gillnet ranged between 20.2-62.2 cm FL with an average was 40.2 cm FL and weight between 147-4,205 g with an average was 1,400.7 g. The growth pattern of giant catfish was positive allometric was expressed by equation W=0.0158 × L3.0546, r2 = 0.9775. Condition factor of giant catfish was ranging from 1.8-2.1.

ABSTRAKDalam rangka mendeskripsikan pemanfaatan dan inisiasi pengelolaan perikanan tuna neritik di WPPNRI 573, telah dilakukan penelitian dengan mengambil kasus perikanan tuna neritik berbasis di PPN Prigi-Jawa Timur. Data diperoleh melalui program port sampling pada tahun 2013-2017. Hasil penelitian menunjukkan produksi tuna neritik yaitu tongkol lisong (BLT), tongkol krai (FRI), tongkol komo (KAW), dan tongkol abu-abu (LOT) rata-rata sebesar 8.120 ton per tahun. Dari jumlah tersebut, 99,56% diproduksi melalui perikanan pukat cincin (PS) dan sisanya dari perikanan jaring insang hanyut ( d GN), payang (DS), dan pancing tonda-pancing ulur (TRs HL dan d HL). CPUE nominal PS selama 5 tahun terakhir terus menurun, rata-rata 0,891 ton/hari. Komposisi jenis tangkapan PS meliputi BLT (91,52 %), FRI (6,68 %), KAW (1,78 %) dan LOT (0,01 %). Sebanyak 99% BLT yang tertangkap PS merupakan ikan yuwana, sedangkan FRI, KAW, dan LOT sebagian besar tertangkap pada ukuran dewasa masing sebanyak 73%, 70%, dan 55%. Tuna neritik termasuk spesies peruaya jauh, maka pengelolaannya di WPPNRI 573 harus mengacu pada acuan pengelolaan Indian Ocean Tuna Commission (IOTC). Mengacu hasil Work Party Neritic Tuna (WPNT) IOTC tahun 2016 dan 2018, maka pengelolaan perikanan tuna neritik di WPPNRI 573 berbasis di PPN Prigi adalah sebagai berikut: (1) hingga 2025 jumlah hasil tangkapan BLT dan FRI harus dikendalikan masing-masing pada jumlah 9.818 ton dan 48 ton per tahun; (2) hingga 2023 tangkapan KAW ditetapkan pada jumlah ± 98 ton per tahun (80% jumlah tangkapan tahun 2013); dan (3) hingga tahun 2025 jumlah tangkapan LOT disarankan sama dengan tangkapan 2015 yaitu ± 1.13 ton per tahun. ABSTRACTTo describe the utilization and management initiation of tuna neritic fisheries in the Indonesian FMA-RI 573, a research has been conducted by taking the case at the Prigi Fishing Port, East Java. Data were obtained through the port sampling program in 2013 show that the production of neritic tuna, namely bullet tuna (BLT), frigate tuna (FRI), kawa-kawa (KAW), and longtail tuna (LOT) was 8,120 tons per year on average. 99.56% of the amount were produced by purse seine (PS) fisheries, the rest came from drifting gill nets ( d GN), danish-seine (DS), and the combination of trolling line and surface-deep hand line (TRs HL and d HL) fisheries. The nominal CPUE of PS over the past 5 years has continued to decline, averaging 0.891 tons/day. The composition of PS catches includes BLT (91.52%), FRI (6.68%), KAW (1.78%) and LOT (0.01%). Large numbers (99%) of the BLT caught by PS were juvenile fish, while at the same time FRI, KAW, and LOT were mostly caught at the adult stage. Neritic tuna is a highly migratory species, so its management in the Indonesian FMARI 573 must refer to the Indian Ocean Tuna Commission-DOI: http://dx. WPNT-IOTC in 2016 and2018, the management of neritic tuna fisheries in the Indonesian FMA-RI 573 based at Prigi Fishing Port is as follows: (1) up to 2025, the catches of BLT and FRI must be controlled at 9,818 and 48 tons per year, respecti...

Digitalization of capture fisheries data becomes inevitable in the present and future time. The use of Information and Communication Technology (ICT) in the fisheries sector is widely applied, creating a bigger and better database. Development of the database offers the utilization of Big Data and Decision Support System (DSS) to provide robust analysis, simulate better scenarios, formulate recommendations, and propose management measures to support successful fisheries management in achieving sustainability and profitability objectives. Bali Strait sardine stock estimation has been conducted several times through several approaches and techniques. This study will combine the available times series catch and effort data from published statistic landing data and publications with real-time data from electronic catch monitoring in Muncar and Pengambengan fishing port. The sardine stock and fishery status estimation were analyzed using a stock-production model incorporating covariates (ASPIC), a Nonequilibrium surplus-production model to data on fish catch and relative abundance. Another purpose of this study is to increase stakeholder participation through a smart dashboard system that enables automatic data analysis, faster recommendations socialization, and engagement. Increased stakeholder participation in fisheries management will be a crucial factor in achieving operational and successful fisheries management.

Illegal, unreported, and unregulated fishing yang disingkat menjadi IUU fishing telah mengakibatkan kerugian global hingga 10-23.5 miliar USD. Penanganan IIU Fishing selama ini lebih fokus pada illegal fishing, padahal dampak dari pelanggaran unreported fishing juga tidak kalah dahsyatnya. Unreported fishing menyebabkan kesalahan data perikanan yang banyak digunakan dalam penentuan kebijakan perikanan. Hasil penelitian menunjukkan bahwa data hasil tangkapan armada pancing tonda pada periode tahun 2012-2022 di PPN Palabuhanratu terindikasi terjadi misreported sebesar 46,52 – 228,02 ton/tahun atau mencapai 11,7 – 28,8% dibawah tangkapan yang sebenarnya. Ketidaksesuaian dan kesalahan pendataan tersebut disebabkan oleh beberapa sebab, diantaranya adalah: penggunaan hasil tangkapan untuk umpan, dikonsumsi di atas kapal, jatah ABK dan upah tenaga kerja pada saat bongkar muatan. Beberapa fakta tersebut mendorong perlunya perbaikan sistem pendataan hasil tangkapan dengan melakukan identifikasi dan kuantifikasi adanya potensi terjadinya misreported data hasil tangkapan sehingga pengelolaan perikanan dapat dilakukan secara tepat dan benar.
