Abstract

Eel (Anguilla bicolor) in the grow-out culture requires good fingerling seeds. Increasing the eel productivity can be done by increasing the stocking density, that should be balanced with good environmental and feed management. This study aimed to analyze the production and business performance of fingerlings in a recirculation system to increase the eel survival and growth rate. The study used a completely randomized design with three different stocking densities, namely 4 g/L (A), 5 g/L (B), and 6 g/L (C). The average weight of each fingerling was 20 ± 4.09 g, that was kept in a 1.5-m3 pond with a recirculation system. Feeding was performed two times a day using commercial feed with probiotic supplementation. The results showed that different stocking densities significantly affected feed conversion ratio, total biomass weight, and coefficient of variance. However, different stocking densities had no significant effect on survival rate, absolute weight growth rate, specific weight growth rate, and condition factor. The C treatment obtained the highest profit with an R/C ratio of 1.20 ± 0.03. The best production and cultivation performance of eel fingerling in a recirculation system with different stocking densities is found in treatment C (6 g/L). Keywords: Anguilla bicolor, business performance, production performance, recirculation system, stocking density ABSTRAK Budidaya ikan sidat (Anguilla bicolor) pada segmen pembesaran memerlukan benih yang baik khususnya untuk benih fingerling. Upaya peningkatan produksi benih ikan sidat dapat dilakukan dengan peningkatan padat tebar yang diiringi dengan manajemen lingkungan dan pakan yang baik. Tujuan penelitian ini menganalisis kinerja produksi dan kinerja usaha pada pemeliharaan fingerling dalam sistem resirkulasi sehingga meningkatkan kelangsungan hidup dan pertumbuhan. Penelitian menggunakan rancangan acak lengkap yang terdiri atas 3 perlakuan padat tebar dengan tiga ulangan, yaitu padat tebar 4 g/L (A), 5 g/L (B), dan 6 g/L (C). Fingerling ikan sidat yang digunakan berbobot awal 20 ± 4,09 g/ekor, yang dipelihara dalam bak 1,5 m3 dengan sistem resirkulasi. Pakan diberikan dua kali sehari berupa pakan buatan komersial yang diberi probiotik. Hasil penelitian menunjukkan bahwa padat tebar berpengaruh nyata terhadap parameter rasio konversi pakan, laju pertumbuhan mutlak biomassa, dan koefisien keragaman bobot tetapi tidak berpengaruh nyata terhadap tingkat kelangsungan hidup, laju pertumbuhan mutlak bobot, laju pertumbuhan spesifik bobot, dan faktor kondisi. Hasil analisis kinerja usaha budidaya fingerling dengan padat tebar berbeda menunjukkan berbeda nyata dan sebanding dengan kinerja produksi. Perlakuan C memberikan keuntungan tertinggi dengan rasio R/C sebesar 1,20 ± 0,03. Kinerja produksi dan kinerja usaha budidaya fingerling ikan sidat (Anguilla bicolor) dalam sistem resirkulasi dengan padat tebar berbeda terbaik terdapat pada perlakuan C (6 g/L). Kata kunci: Anguilla bicolor, kinerja produksi, kinerja usaha, padat tebar, sistem resirkulasi

Abstract

Increasing of the fisheries problems, especially the decline of fisheries resources stock, made the sustainable issues become intense discussed in fisheries. The importance of the system indicator for fisheries sustainable development are widely known and have been done in several countries through tremendous effort in their fisheries development. In Indonesia, the assessment of fisheries sustainability has been carried out with various approaches to sustainability assessment, mostly on management status. This study aims to assess the rate of sustainable development and management of the reef fisheries in Indonesia using the integrated index approach of sustainability aspect using the multi-dimensional scaling procedures with a case study of reef fisheries at Ternate Island. The result shows that the sustainable development index of reef fisheries at the coastal area of Ternate Island tends to move toward sustainable development within integrated management from all sustainable dimensions. Dimensionally, economic and social dimensions show a positive trend on sustainable development, while ecological and technological dimensions tend to show the inverse direction. The relationship between economic and social benefits obtained from reef fisheries to improving the community well-being will provide a positive trend for the sustainability of reef fisheries. However, on the other hand, the increase in production can lead to overfishing for the reef fisheries resources. Management policy that integrated every indicator of sustainable fisheries dimension may extend the chance to develop reef fisheries at the coastal area of Ternate Island within the sustainability of the resources and ecosystems management.Keywords: Sustainable development, integrated management, fisheries management, sustainability index, coral reef

Abstract

Jatigede Reservoir receives water masses and materials from the Cimanuk River, such as nutrients, sediments, and waste, including microplastics. This study aims to analyze the presence of microplastics in the digestive tract of caught fish in Jatigede Reservoir. Fish samples were obtained from fishermen, fish collectors, and fish farmers. Microplastic observations were carried out in the stomach and intestines of fish through the stages of observing fish eating habits, extraction, followed by FTIR analysis to determine the presence, abundance, and type of polymer. Carnivorous fish have the highest amount of microplastics. There is a marked difference between the amount of microplastics and the origin of fish intake. The shorter the fish's gut, the greater the amount of microplastics found. Based on their shape, the type of microplastic is dominated by fibers with a blue color. The most common polymer found is nylon. The digestive tract of fish in Jatigede Reservoir already contains microplastics of various types and colors, with varying amounts, according to the nature of eating fish.

Abstract

Information abundance and distribution of fish larvae in coastal waters of East Lampung currently very limited. The research aimed to improve the knowledge of the early life of organisms, in order to manag biodiversity and biological resources in the waters. Research station representing the several water sectors: in-shore, near-shore, and off-shore. The research was a representation of eastern monsoon (June) and transition monsoon (September) in 2017. Fish larvae was harvested using bonggo-net tool while its identification to family level using portable Dino-lite. Based on the result the Abundance of fish larvae in eastern monsoon was higher than transition monsoon. This research found 81 families of fish larvae. There were 10 dominant families, that are Gobiidae, Pegasidae, Mullidae, Pomacentridae, Sillaginiidae, Bleniidae, Bythitidae, Carangidae, Pseudochromidae and Bothidae. The distribution of fish larvae in the lower in-shore was higher than near-shore and off-shore, while east and transitional seasons have not much different larval catches.  Temperature, salinity and pH parameters indicated optimal range state for survival and growth of fish larvae, brightness and turbidity in accordance with water quality standards, currents velocity on eastern monsoon is very fast while transition monsoon is fast to very fast. Phytoplankton and zooplankton showed sufficient natural food availability for the life of fish larvae. Result Canonnical Corespondence Analysis (CCA) analysis to connectivity of abundance and larvae distribution showed that the brightness parameter forming a point projection while other water environment condition parameters form a vector projection in both period of monsoon. The abundance and fish larvae distribution in coastal waters of East Lampung in all three sectors of the waters had proportionality to the parameters of environmental conditions, especially the current parameters and the difference of the monsoon period.

Abstract

Mangrove ecosystems are crucial for sustaining tropical coastal environments and play a vital role in climate change mitigation through their capacity to sequester and store blue carbon in both vegetation and sediment. Despite their ecological value, mangroves in Jakarta Bay are under increasing pressure from coastal development, land conversion, pollution, and unsustainable exploitation. These anthropogenic threats reduce mangrove cover and diminish their ability to function as carbon sinks. This study examined mangrove carbon stocks at four locations Muara Village, Kapuk Muara, Marunda, and Muara Jaya Village through vegetation surveys, biomass measurement, and the calculation of the Important Value Index (IVI) to analyze species composition and dominance. The results demonstrated considerable variation in biomass and carbon reserves across sites. Muara Village recorded the highest biomass (558.72 tons ha⁻¹) and carbon stock (262.59 tons ha⁻¹), followed by Kapuk Muara (411.18 tons ha⁻¹), Muara Jaya (365.39 tons ha⁻¹), and Marunda, which had the lowest values (208.9 tons ha⁻¹). Dominant species included Rhizophora mucronata and Avicennia marina, reflecting their ecological adaptability and contribution to blue carbon storage. The findings emphasize that mangrove areas with higher biomass and carbon reserves are critical for maintaining ecosystem resilience in Jakarta Bay. Conservation and restoration should therefore prioritize sites with strong carbon storage potential, while degraded areas require rehabilitation to enhance ecological services. Strengthening mangrove management will not only support biodiversity and coastal protection but also contribute significantly to regional climate change mitigation strategies through the preservation of blue carbon.

Abstract

Viabilitas glass eel menentukan keberhasilan budidaya dan mengatur variabilitas rekrutmen, masing-masing sebagai benih dalam akuakultur dan populasi liarnya. Penelitian ini bertujuan untuk mengkaji kualitas glass eel melalui pengukuran biometrik dipasangkan dengan analisis proksimat. Pengumpulan glass eel dilakukan setiap bulan dengan menggunakan alat tangkap sirib di Muara Cimandiry selama bulan Desember 2020 - April 2021. Aspek biometrik yang diukur adalah panjang, berat, diameter mata, jantung, dan hati, sedangkan proksimat adalah kandungan protein, lemak, karbohidrat, dan abu. Hasil penelitian menunjukkan bahwa panjang dan berat badan terus bertambah setiap bulannya, meskipun faktor kondisi tidak memperlihatkan perbedaan. Diameter mata dan bukaan mulut mengkonfirmasi penglihatan ikan predator diurnal. Jantung dan hati menunjukkan kemampuan metabolisme pada ikan perenang cepat sebagai ikan bermigrasi katadromus. Protein, lemak, karbohidrat, dan abu berfluktuasi antar bulan, meskipun perbandingan antar bulan tidak signifikan. Tidak ada konfirmasi yang jelas dari analisis proksimat pada karakter biometrik. Namun glass eel dengan ukuran terbesar pada Bulan April mungkin yang terbaik untuk benih budidaya.

Abstract

Pesisir Kabupaten Lampung Timur merupakan sentra budidaya udang vaname (Litopenaeus vannamei). Namun, daerah ini mengalami fluktuasi produksi, di mana produksi periode tahun 2019-2021 mengalami penurunan dari 10.504 ton menjadi 5.903 ton. Tujuan penelitian ini untuk mengevaluasi kesesuaian fisik lahan serta kualitas air dan tanah tambak pemeliharaan udang vaname yang diklasifikasikan ke dalam dua tingkat teknologi budidaya: tradisional dan semi-intensif atau intensif. Lokasi penelitian berada di pesisir Kabupaten Lampung Timur. Parameter yang diukur (1) kesesuaian fisik lahan meliputi ketinggian lahan, penggunaan lahan, jarak dari pantai, dan jarak dari sungai; (2) kualitas air terdiri dari suhu, salinitas, pH, oksigen terlarut, alkalinitas, amonia, nitrit, nitrat, serta fosfat; dan (3) kualitas tanah berupa pH dan jenis substrat sedimen. Tingkat kesesuaian fisik lahan dianalisis menggunakan sistem informasi geografis dengan metode tumpang susun (overlay) peta. Kesesuaian kualitas air dan tanah berpedoman pada Peraturan Menteri Kelautan dan Perikanan Nomor 75 Tahun 2016. Hasil evaluasi kesesuaian lahan untuk tambak tradisional menunjukkan 491,45 ha masuk kategori sangat sesuai (S1) dan sesuai (S2) serta 9.662,61 ha sesuai marjinal (S3). Untuk tambak semi-intensif atau intensif seluas 11,61 ha masuk kategori S1 dan S2 serta 10.416,58 ha kategori S3. Nilai hasil uji kualitas air dan tanah bervariasi di tiap titik pengujian, namun umumnya sesuai, hanya salinitas tambak semi-intensif atau intensif tercatat tidak sesuai standar budidaya udang vaname. Hasil penelitian menyimpulkan lokasi tambak di lahan S3 dan ketidaksesuaian salinitas menjadi faktor yang memengaruhi secara langsung keberhasilan budidaya dan stabilitas produksi udang.The coastal area of East Lampung Regency is one of the main centers for whiteleg shrimp (Litopenaeus vannamei) aquaculture in Lampung Province. However, the area’s shrimp production has highly fluctuated. For example, in 2019-2021, the production decreased from 10,504 tons to 5,903 tons. This study aimed to evaluate the land suitability, water and soil quality of shrimp ponds located in the coastal of East Lampung Regency which use two types of farming technology: traditional and semi-intensive or intensive. The measured parameters included: (1) physical suitability parameters: land height from sea level, land use, distance from the beach and river; (2) water quality parameters: temperature, salinity, pH, dissolved oxygen, alkalinity, ammonia, nitrite, nitrate, and phosphate; and (3) soil quality parameters: pH and types of sediment. The level of land suitability was determined using the geographic information system (GIS) approach, in which a weighted overlay method was employed. The suitability classification of water and soil quality was based on the standard in the Decree of the Minister of Marine Affairs and Fisheries Number 75/2016. The results showed that 491.45 ha was categorized as highly suitable (S1) and suitable (S2) and 9,662.61 ha as marginally suitable (S3) for traditional farming. For semi-intensive or intensive farming were located in the S1 and S2 of 11.61 ha and S3 category of 10,416.58 ha. Water and soil quality varied in each research site but generally still met the required standard, only the water salinity of the semi-intensive/intensive did not meet the required standards of whiteleg shrimp farming. The study concludes that the location of the ponds in S3 land and the inappropriate salinity directly affect the success and stable production of shrimp farming in the area.

Abstract

Badan Sungai Sebangau, Kalimantan Tengah, terbagi atas induk sungai sebagai wilayah umum dan anak sungai sebagai wilayah penangkapan ikan terkontrol melalui pengelolaan berbasis hak. Di sisi lain, sebagian lintasan sungai tersebut merupakan batas terluar kawasan konservasi Taman Nasional Sebangau (TNS). Tujuan penelitian adalah untuk mengidentifikasi kinerja pengelolaan perikanan berbasis hak di Sungai Sebangau tersebut. Penelitian dilakukan pada bulan Oktober hingga Desember 2019 dengan lokasi penelitian yang mencakup kawasan induk sungai dan tiga anak sungainya, yaitu Sungai Bakung, Rasau, dan Bangah. Metode yang digunakan adalah kualitatif deskriptif, didukung oleh data primer yang dikumpulkan melalui observasi, wawancara, dan dokumentasi, dan data sekunder yang diperoleh melalui penelusuran dokumen terkait. Informan utama dalam pengumpulan data primer adalah nelayan sungai. Proses analisis data terdiri atas reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan sebagai berikut. Dari aspek sumber daya, diperoleh bahwa hutan rawa gambut membawa pengaruh langsung pada kondisi sungai, yang ditandai oleh keberadaan delapan famili ikan di sungai tersebut dan warna air sungai yang cenderung kehitaman. Dari aspek sosial kelembagaan diperoleh hasil bahwa: (1) nelayan memanfaatkan keberadaan modal sosial berupa pola kekeluargaan dan kekerabatan yang merupakan pondasi kehidupan bermasyarakat, (2) kegiatan penangkapan menjadi perekonomian utama, namun pendapatan nelayan mempunyai tingkat ketidakpastian tinggi, (3) nelayan didukung oleh damang, tenaga fasilitator dari Balai TNS, dan WWF Kalimantan Tengah sebagai aktor pengelola sungai dan membentuk interaksi asosiatif dan disosiatif. Penelitian memberikan arahan untuk mengukuhkan aturan dalam mempertahankan pengelolaan perikanan perairan darat berbasis hak di Sungai Sebangau.Titlle:  Rights-Based Inland Water Fishery Management In Sebangau River, Sebangau National Park Central KalimantanThe Sebangau River, Central Kalimatan, consists of mainstream as common area and tributaries as controlled area of fishing ground by means of rights-based management. On the other hand, the river constitute outer boundary of the Sebangau National Park (SNP) conservation area in Central Kalimantan. The research objective was to identify the rights-based fisheries management in Sebangau River. This study was conducted in October to December 2019 and was located on the mainstream and three tributaries, they are Bakung, Rasau, and Bangah River. The study used descriptive qualitative method with primary data that were collected from observation, interviews, and documentation, as well as secondary data that were collected from document study. The main informants were fishermen. The process of data analysis involves data reduction, data presentation, and conclusions. The research represented some findings. On resource aspect, it was found that peat swamp forest directly affected the condition of the river. It was indicated by the occurrence of eight fish families and the black colour of river water. On the social institutional aspect, it was found that: (1) Kinship systems were the social capital for the foundation of social life, (2) Fishing is the main economic activity, but it has a high level of income uncertainty for the fishers, (3) The fishers are supported by damang, facilitators from Balai TNS, and WWF Central Kalimantan as river management and building associative and dissociative interactions. This study provides direction for enforcing the rules in maintaining a rights-based inland fisheries management system in Sebangau River.

Abstract

White Spotted Wedgefish (Rhynchobatus australiae) is one of the member Elasmobranch family which is categorized as an endangered species. The R. australiae is the main target by fishers in Tanjung Luar and Maringkik Island. This study was aimed to analyze ecobiological aspect and to estimate economical incentive value of R. australiae fisheries in Tanjung Luar. The Total of 616 samples were collected from Tanjung Luar Fishing Port from 2017-2021, consisting of 64 males and 552 females. Total 150 fisher respondents from Tanjung Luar and Maringkik Island were interviewed. R-Studio software was used to estimate the ecobiological aspects based on life history parameters. Contingent Valuation Method (CVM) and Discrete Choice Experiment (DCE) were used to estimate economical incentive. The result show that the average length of R. australiae was 213,12 ± 2,63 (cmTL) which is accordance with the regulation. However, the sample of R. australiae was dominated by immature size fish. The growth rate of female R. australiae was lower and have a longer lifespan than male. The condition of R. australiae in Tanjung Luar waters was categorized as biological overfishing. The value of Total Willingness to Pay (WTP) for R. australie conservation was Rp11.226.000/month, whereby the value for individual was Rp.62.340/person. Education and income are the most significant variables affecting WTP.
