Abstract

Pengelolaan perikanan merupakan komponen penting dari pengelolaan sumber daya perairan (stok spesies, dan lingkungannya). Sumber daya perikanan memiliki definisi yang komprehensif dan, secara umum, merujuk pada semua hewan yang sebagian besar menghuni habitat perairan dan ditangkap oleh manusia. Berkurangnya  stok disebabkan tingginya produktifitas penangkapan, yang dipenggaruhi penggunaan armada alat tangkap. Armada alat tangkap harus dapat memperhitungkan setidaknya tiga dampak utama, yaitu: (1) dampak lingkungan, (2) dampak terhadap kelimpahan sumber daya dan (3) dampak pada target stok sumberdaya ikan. Penelitian ini dilakukan bulan Maret – Juni 2023 di Pelabuhan Brondrong. Metode yang digunakan pada penelitian ini adalah metode deskriptif dengan cara wawancara, observasi, dokumentasi Tujuan Penelitian ini mengetahu informasi nelayan sebagai pengguna langsung terhadap  keberadaan sumberadaya  ikan tentang  Penangkapan ikan dengan dampak rendah dan hemat bahan bakar (LIFE (Low impact and Fuel Efficient) FISHING. Berdasarkan  hasil penelitian Low Impact (Dampak Rendah), alat tangkap yang memiliki kontribusi paling besar terhadap lingkungan perairan yaitu cantrang dengan nilai 34%, alat tangkap payang sebesar 41%, pancing ulur 65%, dan rawai sebesar 64%. Jadi, alat tangkap yang memiliki kontribusi paling rendah adalah rawai dan pancing ulur, kemudian payang dan cantrang. Berdasarkan fuel efficient (efisiensi bahan bakar), alat tangkap yang memiliki tingkat efesiensi bahan bakar paling baik yaitu alat tangkap rawai dan pancing ulur dengan nilai 67%, kemudian payang dengan nilai 59%, dan cantrang dengan nilai 42%. Hal tersebut dikarenakan pengaruh ukuran kapal, jarak trip, dan lama trip kapal rawai dan pancing ulur dan rawai lebih sedikit dari alat tangkap payang dan cantrang  . Hasil penelitian ini merekomidasi penggunaan alat tangkap rawai dan pancing dikarenakan ramah lingkungan dan efeisiensi bahan bahar.Fisheries management is essential to aquatic resource management (species stocks and their environment). Fisheries resources have a comprehensive definition and generally refer to all animals that predominantly inhabit aquatic habitats and are caught by humans. Stock depletion is caused by high fishing productivity, which is influenced by the use of fishing gear fleets. Fishing gear fleets must be able to take into account at least three main impacts, namely: (1) environmental impacts, (2) impacts on resource abundance, and (3) impacts on target stocks of fish resources. This research was conducted from March to June 2023 at Brondrong Harbor. The research methodology employed in this study is descriptive, utilizing interviews, observations, and documentation. The purpose of this study is to determine the information of fishermen as direct users of the existence of fish resources about Fishing with low impact and fuel-efficient LIFE (Low impact and Fuel Efficient) FISHING. Based on the Low Impact study results, the fishing gear with the most significant contribution to the aquatic environment is cantrang with a value of 34%, payang gear with 41%, handline with 65%, and longline with 64%. So, the fishing gear with the lowest contribution is longline and handline, then payang and cantrang. Based on fuel efficiency, the fishing gear with the best fuel efficiency is longline and hand line fishing gear with a value of 67%, then payang with a value of 59%, and cantrang with a value of 42%. This refers to the influence of vessel size, trip distance, and trip length of longline and handline and longline vessels which are less than payang and cantrang fishing gear. The study suggests using longline and fishing gear due to their environmental friendliness and material efficiency.

Abstract

Rajungan merupakan salah satu komoditas unggulan sektor perikanan tangkap di perairan yang ditangkap menggunakan jaring insang dan bubu / bubu lipat. Potensi hilangnya kedua alat tangkap tersebut saat dioperasikan sangat tinggi, baik disebabkan oleh faktor cuaca, kondisi dasar perairan maupun interaksi dengan alat tangkap lain. Tertinggalnya alat tangkap di perairan yang lebih dikenal dengan istilah Abandoned, Lost or Discarded Fishing Gear (ALDFG) memberikan kontribusi signifikan terhadap melimpahnya marine debris (sampah laut) di laut yang memberikan dampak negatif terhadap kelestarian sumberdaya ikan, kualitas perairan dan membahayakan keselamatan pelayaran. Meskipun demikian, belum ada upaya mitigasi dan pengurangan ALDFG di perairan laut. Penelitian ini bertujuan untuk melakukan identifikasi penyebab tertinggalnya alat tangkap pada perikanan rajungan di perairan laut.  Pengumpulan data dilakukan di kabupaten Demak, Jawa Tengah pada bulan Agustus dan September 2023 dengan metode wawancara terhadap responden yang dipilih secara sengaja di sekitar pendaratan nelayan rajungan, yang hasilnya kemudian dianalisis secara deskriptif. Studi ini menemukan bahwa sumber sampah laut yang berasal dari alat tangkap rajungan khususnya adalah disebabkan oleh alat tangkap yang hilang bukan karena sengaja dibuang ke laut. Alat tangkap yang hilang terjadi karena faktor alam (23%) dan atau diterjang oleh pengoperasian alat tangkap jenis lainnya (27%).   Blue swimming crab is one of the leading commodities in the capture fisheries sector in waters which are caught using gill nets and traps/bubu lipat. The potential for loss of these two fishing gears during operation is very high, both due to weather factors, bottom conditions of the waters and interactions with other fishing gears. Leftover fishing gear in the waters known as Abandoned, Lost or Discarded Fishing Gear (ALDFG) contributes significantly to the abundance of marine debris in the sea which has a negative impact on the preservation of fish resources, water quality and endangers shipping safety. Even so, there have been little efforts to mitigate and reduce ALDFG in marine waters. This study conducted at Demak of Central Java from August to September 2023 which aims to identify the causes of fishing gear debris in crab fisheries in marine waters. Data collection was carried out by in-depth interviews with respondents who were deliberately selected around the crab fishermen's landings, the results of which were then analyzed descriptively. This study found that the source of marine debris originating from swimming crab fishing gear was caused by lost fishing gear, not because it was intentionally thrown into the sea. Lost fishing gear occurs due to natural factors and is affected by the operation of other types of fishing gear by 23% and 27% respectively.

Abstract

Fourfinger threadfin Eleutheronema tetradactylum has a local name, namely laosan fish by the coastal community of Lekok Pasuruan District, a type of demersal fish that can swim in brackish waters. This research aimed to determine the biological aspects, namely the relationship of Length to Weight, sex ratio, and to determine the feasibility of catching based on the measurement results of the length of the first caught (Lc) and the length of the gonads first ripened (Lm). This research was conducted based on catches during Januari - March 2020 for total samples of as much as 450 fish, based on the catch of gill nets. The result informed that the length and weight relationship was negative allometric. The sex ratio between male and female was 1.00: 0.00. During the study, no female gonads were found because the fourfinger threadfin had spawned protandrous hermaphrodites. The value of length at first maturity (Lm) and length at first capture (Lc) was 20.99 ± 0.13 cm and 24.66 ± 0.046 cm. Lc > Lm's value proves that the fish caught is dominant gonad ripe fish so that the fish is suitable for catching and the fishing gear used selectively.

Abstract

Shark and ray fishery issues raised in Indonesia as some species have been listed in the IUCN red list. In relation to the conservation of some shark and ray species, critical information is required related to several biological aspects to assure its fishery sustainability. This study was conducted in Brondong Fishing Port in February – March 2020. Length, weight, and maturity level data were collected from 272 shark individuals and 267 ray individuals. Several analyses were performed, such as length-weight relationship analysis, sex ratios, and maturity level analysis. The study found 18 species listed in the IUCN red list were dominantly composed of Carcharias taurus and Dasyatis kuhlii. Both species have negative allometric, while the sex ratios showed that the ratio of the number of male and female individuals for shark and ray are 1:5 and 1:2, respectively. The maturity level of male individuals for Carcharias taurus pointed that 33% full calcification (FC), 17% non-full calcification (NFC), and 50% non-calcification (NC), while for Dasyatis kuhlii resulted that 66% FC, 28% NFC, and 6% NC. It is concluded that the biological aspects of the dominant species indicated that most individuals were in a critical state, thus it is required to monitor and control their fishing pressures.

Abstract

Penelitian ini bertujuan untuk mengkaji pengaruh muson dan arus laut terhadap distribusi dan komposisi sampah di kawasan Ekowisata Mangrove Wonorejo, Surabaya. Dengan menggunakan metode survei garis pantai di lima lokasi penelitian, data sampah dikumpulkan pada Maret, Mei, dan September 2024. Analisis terfokus pada pengukuran jumlah dan berat sampah terutama plastik, karet, kain, dan bahan lainnya. Hasil menunjukkan bahwa sampah plastik adalah yang paling dominan, mencapai 95,33% dari total berat sampah pada September, sedangkan pada bulan Maret dan Mei, jumlahnya juga sangat tinggi. Lonjakan signifikan dalam sampah karet tercatat pada Mei, kemungkinan disebabkan oleh kegiatan rekreasi yang meningkat selama musim liburan. Pola perubahan sampah menunjukkan bahwa muson barat (Desember-Maret) yang membawa curah hujan tinggi menyebabkan peningkatan akumulasi sampah di pantai, terutama plastik dan karet, karena aliran permukaan yang membawa sampah dari daratan ke pesisir. Sebaliknya, pada muson timur (Juni-September), yang umumnya lebih kering, terjadi penurunan jumlah sampah yang terakumulasi, terutama plastik, karena arus laut yang bergerak menjauh dari pantai mengurangi penumpukan sampah di pesisir. Mangrove berperan penting sebagai filter alami, menangkap dan mengurangi sampah yang masuk ke ekosistem pesisir. Berdasarkan temuan ini, disarankan peningkatan fasilitas pengelolaan sampah dan edukasi publik tentang pengurangan penggunaan plastik sekali pakai untuk mengurangi dampak negatif sampah pada ekosistem mangrove.   This study was conducted to understand the influence of monsoons and ocean currents on the distribution and composition of waste in the Wonorejo Mangrove Ecotourism, Surabaya. Using a shoreline survey method at five locations, waste data was collected in March, May, and September 2024. The analysis focused on measuring the amount and weight of waste, especially plastic, rubber, cloth, and other materials. The results showed that plastic waste was the most dominant, reaching 95.33% of the total weight of waste in September, while in March and May, the amount was also very high. A significant spike in rubber waste was recorded in May, possibly due to increased recreational activities during the holiday season. The pattern of waste changes showed that the west monsoon (December-March) which brought high rainfall caused an increase in the accumulation of waste on the beach, especially plastic and rubber, due to surface flow carrying waste from the mainland to the coast. Conversely, in the east monsoon (June-September), which is generally drier, there was a decrease in the amount of accumulated waste, especially plastic, because the ocean current moving away from the coast reduced the accumulation of waste on the coast. Mangroves play an important role as natural filters, capturing and reducing waste that enters the coastal ecosystem. Based on these findings, it is recommended to improve waste management facilities and public education on reducing the use of single-use plastics to reduce the negative impact of waste on the mangrove ecosystem.

Abstract

Pelabuhan Perikanan Nusantara (PPN) Prigi merupakan salah satu pusat kegiatan perikanan tangkap terbesar di Jawa Timur yang terletak di perairan Samudera Hindia dan masuk dalam Wilayah Pengelolaan Perikanan Negara Republik Indonesia (WPP-NRI 573). Perairan ini didominasi oleh sumberdaya ikan pelagis seperti ikan layang deles (Decapterus macrosoma). Tingginya tingkat pemanfaatan ikan layang di Prigi menunjukkan potensi ekonomi yang besar, namun juga mengindikasikan ancaman terhadap keberlanjutan sumberdaya jika tidak dikelola secara bijak. Penelitian ini perlu dilakukan untuk memberikan pemahaman lebih dalam mengenai aspek biologi ikan layang deles, mengingat tingginya tingkat pemanfaatan yang berpotensi mengancam keberlanjutan sumber daya perikanan jika tidak dikelola dengan baik. Fokus utama penelitian meliputi hubungan panjang-berat, tingkat kematangan gonad (TKG), indeks kematangan gonad (IKG), dan nisbah kelamin ikan layang deles. Penelitian menggunakan metode deskriptif kuantitatif dengan pengambilan sampel secara acak sederhana dari ikan yang didaratkan nelayan menggunakan alat tangkap purse seine. Hasil penelitian menunjukkan pola pertumbuhan ikan layang deles adalah allometrik negatif dengan nilai b sebesar 2,038, yang mengindikasikan pertumbuhan panjang lebih dominan dibandingkan berat. Tingkat kematangan gonad menunjukkan variasi dari TKG I hingga V, dengan nilai indeks kematangan gonad betina lebih tinggi dibandingkan jantan. Analisis nisbah kelamin menunjukkan proporsi ikan jantan dan betina cenderung seimbang dengan hasil uji chi-square yang tidak signifikan. Penelitian ini diharapkan berkontribusi pada pengelolaan perikanan berkelanjutan di WPP-NRI 573.   Prigi Perikanan Nusantara Port (PPN) is one of the largest capture fisheries centres in East Java, located in the waters of the Indian Ocean and included in the State Fisheries Management Area of the Republic of Indonesia (WPP-NRI 573). These waters are dominated by pelagic fish resources such as deles (Decapterus macrosoma). The high level of kite fish utilisation in Prigi indicates great economic potential, but also indicates a threat to the sustainability of the resource if not managed wisely. This research needs to be conducted to provide a deeper understanding of the biological aspects of deles swallow, given the high utilisation rate that could potentially threaten the sustainability of fisheries resources if not managed properly. The main focus of the research included length-weight relationship, gonad maturity level (TKG), gonad maturity index (IKG), and sex ratio of deles flyfish. The study used descriptive quantitative method with simple random sampling of fish landed by fishermen using purse seine gear. The results showed that the growth pattern of Deles flyfish is negative allometric with a b value of 2.038, which indicates that length growth is more dominant than weight. The level of gonad maturity showed variations from TKG I to V, with a higher gonad maturity index value for females than males. Sex ratio analysis showed that the proportion of male and female fish tended to be balanced with non-significant chi-square test results. This research is expected to contribute to sustainable fisheries management in WPP-NRI 573.

Abstract

The southern waters of Java are suitable to be the largest supplier of Yellowfin tuna exports in Indonesia, but have not efficiently produced the expected yield. This research minimizes these constraints by modeling the yellowfin tuna fishing grounds in the southern waters of Java based on oceanographic factors such as Sea Surface Temperature (SST), chlorophyll-a (CHL_A), Sea Surface Salinity (SSS), Sea Surface Height (SSH) using an integration between remote sensing, Geographic Information Systems (GIS), and the Generalized Additive Model (GAM) statistical method. This study used oceanographic factor data from Aqua MODIS Level-3 and Copernicus, while yellowfin tuna fishery production was obtained from Palabuhanratu Nusantara Fishing Port (NFP), Cilacap Ocean Fishing Port (OFP), and Pondokdadap Coastal Fishing Port (CFP). The modeling process used 80% of the data, while the remaining 20% was used to validate the model results. The order of influence of oceanographic parameters from largest to smallest is SST > SSS > SSH > CHL-A. The best model from the GAM analysis showed that the combination of four oceanographic parameters had the greatest influence on yellowfin tuna CPUE. The catch per unit effort (CPUE) of yellowfin tuna was predicted to be high in May-October and low in November-April. The prediction model had high accuracy because most of the fishing activity was in the HSI 0.4-0.5 range and the RMSEP value was 0.63. Yellowfin tuna were suitable in habitats distributed from inshore to offshore in June and July, but less suitable in December.

Abstract

Penelitian ini bertujuan mengidentifikasi spesies kerapu (Epinephelus spp.) serta mengestimasi volume produksi hasil tangkapan kerapu yang tidak tercatat di Tangkahan Kandangsemangkon, Lamongan. Data primer diperoleh melalui identifikasi spesies hasil tangkapan, dan pencatatan volume produksi di Tangkahan Kandangsemangkon. Data sekunder berupa data produksi resmi di Pelabuhan Perikanan Nusantara (PPN) Brondong. Analisis data menggunakan identifikasi visual spesies, kategorisasi spesies pendukung perikanan kerapu berdasarkan Unit of Assessment (UoA). Hasil penelitian menunjukkan terdapat tiga spesies target utama, yaitu Epinephelus fuscoguttatus, Plectropomus maculatus, dan Epinephelus areolatus. Volume produksi yang tidak tercatat selama periode penelitian mencapai 12,33% dari total produksi kerapu di wilayah tersebut. Spesies pendukung yang teridentifikasi terdiri dari enam spesies primer utama, empat spesies primer minor, satu spesies sekunder utama, dan lima spesies sekunder minor. Hasil ini menunjukkan bahwa keterlibatan aktif nelayan dalam   pengumpulan data spasial serta pencatatan produksi secara partisipatif berperan penting dalam memperbaiki akurasi data perikanan untuk mendukung pengelolaan sumber daya yang berkelanjutan.   This research aims to identify grouper species (Epinephelus spp.) and estimate the volume of unrecorded grouper catch production at Tangkahan Kandangsemangkon, Lamongan. Primary data were obtained through the identification of landed species and the recording of production volume at Tangkahan Kandangsemangkon. Secondary data consisted of official production data from the Brondong Fishing Port. Data analysis involved visual species identification and categorization of supporting species for the grouper fishery based on the Unit of Assessment (UoA). The research results indicate the presence of three main target species: Epinephelus fuscoguttatus, Plectropomus maculatus, and Epinephelus areolatus. The unrecorded production volume during the research period reached 12.33% of the total grouper production in the area. The supporting species identified consisted of six major primary species, four minor primary species, one major secondary species, and five minor secondary species. These findings suggest that the active involvement of fishermen in spatial data collection and participatory production recording plays a crucial role in improving the accuracy of fisheries data to support sustainable resource management.
