The Brondong Fishing Port is the largest in East Java. The catches landed in the Brondong fishing port increase, but they are insufficient to meet the raw material necessity of the existing processing industry. The study aims at estimating fish availability and the necessity of raw materials for the fish processing industry in the Brondong fishing port. This research was conducted from January to March 2022 by using a descriptive method. Data were collected through interviews and a literature study. The results revealed that the installed capacity for eight fish processing industries in the Brondong fishing port counted as 123,300 tons/year. Starry triggerfish, Lizard fishes, Streaked spine foot, freckled goatfish, squid, croaker, red snapper, spotted sil, grouper, threadfin breams, hardtail, big eyes, and yellow pike conger were all necessary for the processing industry. In contrast, the estimation of fish availability for the fish processing industry at Brondong fishing port counted as 45,086 tons/year. It indicated a gap between fish availability and the demand from the fish processing industry in the Brondong fishing port. This may impact the fish processing industry's development in the Brondong fishing port. Keywords: Raw material necessity, fish availability, fish processing industry

Understanding the mechanisms that determine the critical habitat of commercial species is one of the significant challenges in marine science, particularly for species that inhabit the vast ocean worldwide. Previous investigations primarily focused on determining skipjack habitats without considering the feasible size for sustainable fisheries. To define habitat hotspots and movement patterns for decently sized skipjack tuna (≥50 cm) in Indonesia Fisheries Management Area (IFMA) 713, Indonesia, we examined the remote sensing of synoptic sea surface temperature (SST) and chlorophyll-a concentration (Chl-a) measurements with catch data from 2007 to 2016. A new skipjack tuna habitat model was developed based on the link between the key satellite-based environmental data and the best tuna fishery performance using a combination of generalized additive models (GAMs) and kernel density estimates. The findings reveal that feasible skipjack catch sizes were found in approximately 27% of total fishing grounds and were significantly captured in areas with a Chl-a of 0.15–0.28 mg m−3 and an SST of 29.5–31.0 °C, corresponding with an elevated skipjack habitat index (SHI). The habitat hotspots for the commercial skipjack were particularly produced by favorable Chl-a and SST, in association with Chl-a front and anticyclonic and cyclonic eddies, especially in October, which coincided with the highest skipjack catch per unit effort (CPUE). Skipjack distributions were mostly found within 10 km of favorable feeding habitats. They used the hotspot area as an indicator of their dynamics and movement pattern in the environment. The observed CPUEs cross-validated the predicted SHI values, suggesting that the model provided a reliable proxy for defining the potential habitats and the spatial movement of mature skipjack schools. Our findings have global significance for locating ecological hotspots, monitoring sustainable skipjack fisheries, and tracking skipjack migration, especially within the western tropical Pacific.

Arad has been prohibited because of its damages to the environment. However, fishers in Muarareja continue to operate the gear even though environmentally friendly fishing gear (traps) have been granted as a substitution. The reason behind the rejection of substitute fishing gear is interesting to be investigated. Therefore, the study aim to 1) analyze fishers' perceptions of arad prohibition, traps, and environmentally friendly fishing gear program; 2) evaluate fishers' perception on policies concerning arad prohibition and fishing gear substitution; and 3) formulate the recommendations. This study involved 35 arad fishers in Muarareja Village who has been granted with traps as substitute fishing gear. Variables in this study are fishers' perceptions on arad and trap, the policy of arad prohibition, and fishers' perception on the environmentally friendly fishing gear program. Data were collected through interviews and questionnaires. Data were analyzed by scoring respondents' answers based on provided statements. The results showed that fishers did not agree that arad is not environmentally friendly, while the trap is. Fishers are also against arad prohibition and refuse to use traps as a replacement. Furthermore, fishers who received traps are still very dependent on arad and use traps only for alternative fishing gear. Recommendations for the policy of arad prohibition are arad should be allowed with special regulation, and further education is required for fishers to understand the correlation between unselective fishing gear and environmental damages. Recommendations for the environmentally friendly fishing gear program are that the provision of traps should be continued with several adjustments following fishermen's preferences. Keywords: Prohibition of arad, environmentally-friendly fishing gear, traps.

Fishing activity to catch hampala (Hampala macrolepidota) using gillnet in the Ranau Lake has been quite intensive. However, there is a type of net developed by fishers to catch hampala in the same waters, namely “jaring kekop.” The existence of this net will increase the intensity of fishing in Ranau Lake which is already high, thus affecting the availability of stocks. The purpose of this research is to describe technical and biological characteristic of kekop net and to analyze the sustainability of kekop net fishery to catch hampala in Ranau Lake, South Sumatera. Data was collected by field survey method through direct interviews with fishers, observation and measurement of fishing unit, and participated in the fishing operation trips. The result showed that the jaring kekop used by fishers in Ranau Lake can be classified into the set gillnet with slightly different operation method from the common set gillnet. The SPR (spawning potential ratio) analysis of hampal fish obtained a value of 72% or > 40%, which means that the average fish caught is gonad ripe or fit to catch (SL50 > Lm). The sustainability values of the jaring kekop fishery were 51.4 for technical aspect, 6.5 for biological aspect, and 65.2 for social-economic aspect. From these sustainability values, it can be seen that the jaring kekop fishery in Lake Ranau is sustainable enough. Key words: jaring kekop, hampala fsih, characteristic, sustainability, Ranau Lake

Fishing with purse seine fishing gear has been carried out by many fishermen, which are generally aimed at catching pelagic fish. Jepara District is one of the coastal areas of the North Coast of Java, located in Central Java Province. This condition makes Jepara Regency have a marine-based economic side of life which has the potential of fish resources that have been used by local fishermen for a long time. The current condition has a tendency to decline in production, which is thought to be due to overfishing. This study aims to obtain an overview of the dominant fish caught by the purse seine and to see the productivity of the purse seine. The research method used is a survey method, by conducting interviews with 20 fishermen, the head of the Ujungbatu Fish Auction Place (TPI) and his staff. The data obtained are data on catch production, composition of types of catch and other data. The results are expected to be able to provide an overview of the dominant fish catch and productivity of purse siene in the waters of Jepara District. The conclusion that can be drawn from this research is that there are three types of fish that are dominant catch, namely layang fish, mackerel and squid. During the last five years (from 2015 - 2019), production tends to experience a significant decline. Meanwhile, the productivity has also decreased as well. Based on the calculation of the productivity level according to KEPMEN KP No.61/2014, the productivity level (2019) of purse seines that land their catch at TPI Ujungbatu Jepara is 4.45, meaning that the production produced in 2019 year is 4.45 tons per vessel 1 GT used.

Ketergantungan nelayan terhadap sumberdaya ikan pada umumnya memiliki tingkat ketergantungan yang tinggi. Oleh karena itu, diperlukan adanya diversifikasi pekerjaan sebagai sumber pendapatan alternatif saat ikan susah didapatkan. Namun untuk melakukan diversifikasi pekerjaan tersebut, maka perlu dilihat terlebih dahulu tingkat ketergantungan nelayan terhadap sumberdaya ikan. Tujuan dari penelitian ini yaitu (1) mendeskripsikan perikanan gillnet di PPI Karangsong, (2) menganalisis tingkat ketergantungan nelayan gillnet di PPI Karangsong terhadap sumberdaya ikan. Perhitungan tingkat ketergantungan menggunakan Multi Cryteria Analysis dengan kriteria yang digunakan yaitu jumlah keluarga, alokasi waktu, pendapatan, dan pengeluaran. Perikanan gillnet di PPI Karangsong didominasi oleh kelompok gillnet 0-10 GT. Kapal gillnet < 25 GT masih menggunakan es, sedangkan kapal ≥ 25 GT menggunakan freezer. Tingkat ketergantungan nelayan gillnet 0-20 GT terhadap sumberdaya ikan lebih tinggi dibandingkan dengan nelayan gillnet > 20 GT.

Unit penangkapan ikan dan pengoperasiannya di Pacitan sangat beragam. Keragamannya menyulitkan pengelolaan perikanan. Memahami dinamika dan karakteristik unit penangkapan ikan, dan pengoperasiannya diperlukan untuk keberhasilan pengelolaan perikanan. Penelitian ini bertujuan untuk menganalisis karakteristik kapal atau perahu penangkap ikan, alat penangkap ikan, nelayan, daerah penangkapan ikan, dinamika pengoperasian alat penangkap ikan, dan menentukan pengelompokkan unit penangkapan ikan.Penelitian ini dilakukan pada bulan Februari, April dan Mei 2013 di Pacitan Kabupaten, Provinsi Jawa Timur. Pengumpulan data dilakukan dengan wawancara pribadi dan observasi. Data dianalisis secara deskriptif dengan tabel, grafik, gambar, dan analisis cluster. Hasil penelitian menunjukkan bahwa kegiatan penangkapan ikan tersebar di sepanjang pesisir Pacitan. Alat penangkap ikan yang dioperasikan adalah kapal motor, perahu motor tempel, dan perahu tanpa mesin. Perahu motor tempel mencapai 84 persen dari populasi perahu di Pacitan. Di sisi lain, alat penangkap ikan yang beroperasi di Pacitan adalah perangkap, pancing, jaring insang, pukat tarik, purse seine, dan jaring angkat. Menggunakan empat parameter (panjang kapal, tenaga mesin, kru, dan alat penangkap ikan) diperoleh setidaknya 6 pola jenis operasi penangkapan ikan. Variasi pola penangkapan ikan disebabkan oleh kemampuan modal dan keterampilan nelayan. Penelitian ini menyimpulkan bahwa unit penangkapan ikan di Pacitan bervariasi dan didominasi oleh perahu motor tempel yang memiliki 6 pola operasi penangkapan ikan

Perikanan karang merupakan salah satu pusat kegiatan penangkapan ikan nelayan kecil di daerah tropis. Seiring dengan perubahan ekonomi dan ekologi, telah mengakibatkan berubahnya pendapatan dan strategi operasi penangkapan ikan. Nelayan telah menggunakan berbagai macam strategi untuk mempertahankan usahanya. Untuk mengkaji hal tersebut, telah dilakukan penelitian di Karimunjawa. Hasil penelitian ini menyebutkan bahwa komposisi ikan hasil tangkapan, produktivitas alat tangkap dan alat tangkap yang digunakan oleh nelayan telah mengalami perubahan dalam periode 2003 – 2005 dan 2009 – 2011. Bila pada periode 2003 – 2005 operasi penangkapan ikan didominasi oleh muroami, maka pada periode 2009 – 2011 trip penangkapan ikan didominasi oleh speargun (panah). Perubahan tersebut, diduga disebabkan oleh berubahnya permintaan pasar khususnya ekor kuning (Caesio sp), biaya operasi penangkapan dan hasil tangkapan baik dalam jumlah maupun komposisi ikan

ABSTRACT The government’s programs on the sustainability of fisheries management had not been fully supported by fishermen. We had conducted a research in Tanjungbalai Asahan, North Sumatra to understand the fishermen’s perception on the criteria’s of environmental friendly fishing gears, perception about the exsistence of fisheries resources, and the compliance to the rule. The results showed that the fishermen who use selective gears (such as: traps and dregdes) had better understanding on the criteria’s of environmentally friendly fishing gears than the fishermen who use unselective gears (such as: trawls and pushnets). The fishermen who use gillnets scored the exsistence of fisheries resources lower than others. The fishermen who use trawls and pushnets had the lowest compliance, while traps had the highest. There was a correlation between fisherman’s perception (about the criteria’s of environmentally friendly fishing gear and about the sustainable fisheries) and the compliance to the rule. Keywords: Code of Conduct for Responsible Fisheries, Compliance, Perception, Sustainable, Tanjungbalai Asahan ABSTRAK Program pemerintah dalam pengelolaan perikanan yang berkelanjutan belum sepenuhnya mendapat respon yang baik dari nelayan. Nelayan banyak yang tidak mematuhi aturan yang berlaku, seperti; penggunaan alat tangkap yang dilarang, tidak memiliki dokumen perizinan, dan tidak melaporkan hasil tangkapan. Penelitian telah dilakukan di Tanjungbalai Asahan, Sumatera Utara yang bertujuan untuk mengetahui persepsi nelayan terhadap kriteria alat penangkap ikan yang ramah lingkungan menurut Code of Conduct for Responsible Fisheries (CCRF), persepsi terhadap keberadaan sumberdaya perikanan, dan kepatuhan terhadap aturan yang berlaku. Hasil penelitian menunjukkan bahwa nelayan yang menggunakan alat tangkap yang lebih selektif (seperti: bubu dan penggaruk) menilai kriteria alat penangkap ikan yang ramah lingkungan lebih baik daripada nelayan yang menggunakan alat tangkap yang kurang selektif (seperti: pukat tarik dan pukat dorong). Nelayan yang menggunakan jaring insang menilai keberadaan sumberdaya perikanan dengan skor yang lebih rendah daripada nelayan lainnya. Nelayan pukat tarik dan pukat dorong memiliki kepatuhan yang paling rendah, sedangkan nelayan bubu memiliki kepatuhan yang paling tinggi. Terdapat korelasi antara persepsi nelayan (persepsi terhadap kriteria alat tangkap ramah lingkungan dan persepsi terhadap keberadaan sumberdaya perikanan) dengan kepatuhan terhadap aturan.

Sea surface temperature (SST) and a-chlorophyll (CHL) were important and they were often used to predict potential fishing ground by using remote sensing. The objectives of the present study were analysis and mapped fishing ground of skipjack in the Banda Sea and its surrounding Moluccas Province according to monsoon. SST and CHL data were taken from satellite citra data analysis, observed by sensor Aqua MODIS level 3 with spatial resolution 4 km and temporal resolution month and monsoon. Citra data were analyzed by using SEADAS 5.2. software. The analysis showed that sea surface temperature (SST) and a-chlorophyll concentration in the Banda Sea and its surrounding fluctuated from month by month. This condition affected seasonal fluctuation of SST and CHL. The average of highest temperature was in West monsoon and first transitional monsoon whereas the lowest was in East monsoon. Otherwise, a-chlorophyll concentration was highest in East monsoon and lowest was in first transitional monsoon. There was a correlation between temperature increasing and a-chlorophyll concentration decreasing. Sea surface temperature has also a negative correlation to CPUE and influenced fishing ground forming. Fishing ground in Banda Sea with highest CPUE during all monsoon was located on Western part of Seram Island: Buano, Kelang and Manipa Islands or situated on 126,70-1280 E and 2,60-3,40 S. The position surrounding Banda Sea lied on 127º-130,3º E and 3,2º-4º S.

ABSTRACT Various policies of fisheries development have been implemented by Indonesian government. However, they have not reached the expected results. Until now the policy/program of empowerment has not been able to significantly increase fishermen income and welfare. Fishermen are still poor and underdeveloped compared to other community groups. Therefore, some corrective measures are needed to improve programs/policies that have been implemented over the years. To get the answer, a study that examines factors affect the success of a fisheries policy is conducted in Indramayu, West Java. By using analysis of Structural Equation Modelling (SEM), the research defines that fisheries institutions factor significantly led to the success of fisheries development. Keywords: fisherman, Indramayu, capture fisheries, SEM ------- ABSTRAK Berbagai upaya pembangunan perikanan tangkap sudah dilakukan pemerintah. Namun demikian, hasil pembangunan perikanan tersebut belum membuahkan hasil seperti yang diharapkan. Sampai saat ini kebijakan/program pemberdayaan belum secara signifikan meningkatkan pendapatan dan kesejahteraan nelayan. Nelayan masih dalam kondisi miskin dan terbelakang dibandingkan kelompok masyarakat lainnya. Oleh sebab itu, diperlukan langkah-langkah untuk memperbaiki program/kebijakan yang telah dilaksanakan selama ini.

Cilacap is the center of the shrimp fishery in Central Java’s south sea. Lately, the shrimp resources in that area have decreased biologically, which is characterized by a decrease in shrimp production trend line. From 2004 to 2008 there was a decrease by 6.3% per year which was caused by large scale utilization in shrimp resources and degradation in carrying capacity. This study aimed to determine influential factors in decreasing shrimp production and to develop strategies for business development in Cilacap’s shrimp fishery. Data were analyzed using the fish-bone diagram and SWOT (Strengths Weakness Opportunities and Threats) analysis. Influential factors in decreasing shrimp production were 1) fishermen; 2) units of fishing; 3) mangrove forests; 4) fishing methods, and 5) shrimp resources stock. Strategies for Cilacap shrimp fishery management were 1) law enforcement in controlling the shrimp capture and mangrove exploitation; 2) the economic development of fishermen and society; 3) integrated shrimp fisheries management; 4) mangrove and aquatic ecosystems rehabilitation; and 5) increase the environmental and shrimp resources carrying capacity.

Utilization of fishing area in Banten Bay by various activities may cause multi sectors conflicts related to management of the bay. The integrated zone system in that area has not been established yet; therefore it is needed to be studied. The objectives of this study were to 1) determine fishing season and fishing ground; 2) determine indicators and criteria of fishing zone; 3) establish fishing zone. The study was conducted in four fish landing centers which are located in Karangantu, Terate, Wadas, and Kepuh from January to April 2010. Data were collected by surveying analyzed using the fishing season index analysis, relationship analysis between sea surface temperature, chlorophyll-a and fish abundance, and GIS analysis. Based on the results, it were revealed that 1) peak fishing season of pelagic fish was from November to January and demersal fish was from November to December; 2) the catches from fishing grounds surrounding Panjang island were anchovies, trevallies, squids, Indian mackerels, pony fishes, Fringescale sardinella; surrounding Pamujan besar island were threadfin bream, shrimps; and surrounding Tunda island were eastern little tuna, narrow barred king mackerels, black pomfret, red snapper, great trevally, scads, mullets, squids; 3) development indicators of fishing zone were (i) feasibility of fishing ground, (ii) compatibility of fishing gears with fishing grounds, (iii) possibility of conflicts, (iv) infrastructure, (v) carrying capacity of environment; 4) Banten bay water was divided into three fishing zones, they were (i) passive zone, (ii) passive and outboard motor zone, (iii) active and inboard motor zone.

Sardine oil (Sardinella lemuru Bleeker 1853) is the one of fish target of fishermen from Banyuwangi and Jembrana who fish in Bali strait. An in-depth study on current utilization rates and over 6 year period is required to obtain information on utilization of the sardine oil. . This study can be used as a guideline in formulating a policy in fishery management to promote sustainable sardine oil resources in Bali Strait. The purposes of this research were to calculate catch per unit effort (CPUE) of fishing gears, determine the standard fishing gears, determine of the production function, and determine feeding habits of sardine oil by analysing the stomach contents. Compared to other fishing gears, CPUE of purse seine has the highest average which made up 332.2032 metric ton per unit. Based on the calculation of the production function, the value of Cmsy was 88,358.71 metric ton per years, and the value of Emsy was 414.601 units. The analysis of the stomach contents showed that sardine oil’s food was plankton which consisted of phytoplankton and zooplankton. During the 6 year period, utilization of sardine oil resources was still allowed, because the highest catch did not exceed Cmsy. However, to sustain the resources, management and regulation in the use of fishing gears, especially purse seine was still needed. It can be done by renewing the joint decree between Governor of East Java and Bali in 1992. Key words: resources analysis, sardine oil fisheries, Bali Strait

ABSTRACT Cilacap waters are rich with shrimp resource, particularly from Penaidae spp species, such as shrimp Jerbung (Penaeus merguensis) and shrimp Dogol (Metapenaeus endevouri and Metapenaeus ensis). Statistic data of shrimp in Cilacap showed shrimp production keep on declining, from 1,118,644 kg in 2004 to 818,595 kg in 2008. The declining production is suspected due to the increasing intensity of catching and the damage of ecology in coastal areas, particularly the mangrove. This research is aimed at mapping the mangrove areas, and estimating stock of shrimp resource in Cilacap. Data analysis was conducted by using spatial analysis and analysis of potential resource of fish. Results of the analysis showed that estimated mangrove forest in Cilacap in 2005 was about 14,502.55 ha, reduced to about 9,326.71 ha in 2007 and continue to decline to about 2,618.78 ha in 2009. Estimated score of MSY shrimp is 955,493.34 kg/year, with optimum catch 55,014.68 trips.

One of ways to increase the fishing operation effectiveness is done by using fish aggregating device (FAD) called rumpon. The types of FAD used in Kei Kecil waters made from bamboos or plastic drum material. This research objectives are (1) determining catch composition around FAD, (2) comparing the effectiveness of two types of FAD on fishing operation, and (3) comparing the effectiveness of fishing gears, operated around the FAD. The method that used in this research was doing survey through observing fishing activities around the FAD. Fishing gear and FAD samples were determined through purposive sampling method. These data were collected from August to October 2007 in Kei Kecil Waters of South East Maluku. The kind of fish catch around FAD were scad mackerel, frigate mackerel, and barred spanish mackerel. The most dominant of catch was scad mackerel (80%), whereas percentage e of frigate mackerel and barred spanish mackerel were 19% and 1%. The composition of the length size of scad mackerel, frigate mackerel, and barred spanish mackerel were dominated by the large size. Type of bamboo FAD was more efective compared with the plastic drum FAD type. Purse seine fishing was more efective compared with gillnet and troll line fishing that operated around rumpon.
