Fish is one of natural resources, which is important for food security. Small pelagic fish is one of the sources of food, the most widely consumed by people of Indonesia, given the existence of a fairly abundant species, and are found in almost entire territorial waters of Indonesia, and also has a relatively affordable price. Management of pelagic fishery in the waters of Indonesia, thus becomes important, especially to maintain the sustainable industry. Optimal and sustainable fisheries industry can only be achieved with proper planning through the implementation of appropriate management instruments as well. Fisheries resources accounting is one of the planning instruments, which should be used as a main reference of Fisheries Management Plan. In general, fisheries accounting provide insights for policy makers on how the flow of the stocks of fish and its relation to changes in the dynamic of natural and economic activity of fishing. Small pelagic resource accounting is one of the mandates of agenda 21 UNCED recommendation, as formulated in the System of Integrated Environmental and Economic Accounting (SEEA). Besides, this is also a decree of Indonesian Law No. 32/2009 regarding the Management and Environmental protection. The paper discusses the fisheries account, both physical and monetary, for small pelagic fish. By using resource accounting, we can understand the dynamics of the availability of stocks of small pelagic fisheries in Indonesia for the sake of food security. The methods in use is the standard bio-economic modelling, using fox algorithm for parameter estimation, and resource accounting method of the System of National Accounts of FAO[1], adapted to the data existing condition.  The results of the analysis, include measurement of standing stocks (physical assets account), fishable biomass, depletion, as well as monetary account. Paper also provides suggestion for management, as well as policy recommendation.Keywords: Small pelagic, Resource Accounting, Physical assets account, monetary account, Fisheries Management Plan, Bio-economic modeling, Policy recommendation.

This paper assesses fish consumption behaviour and perception of fish food security of low-income households using three season survey data from 839 interviews in Ghana. The study profiles the types of fish consumed and employs a modified Cobb–Douglas function to examine the determinants of household expenditure on fish consumption, whilst adopting a 1–5 Likert scale to analyze the perception of fish food security. The results confirm that poor households prefer cheaper and small pelagic fish. The mean expenditure on fish consumption per week is estimated to be GHS 31.15 (Euro 4.94 ≅ 0.16). Additionally, it is demonstrated that marital status, religion, occupation, proximity to local market, and city of residence have a positive and significant influence, whilst level of income, seasonality of fish, and the interaction of religion and seasonality of fish demonstrate a negative and significant influence on fish expenditure. Finally, the paper reveals that the majority of households have the perception that fish is readily available and can be obtained throughout the year in good quality. However, households have varied opinions on accessibility of fish. The paper recommends that the government should support and enhance the value chains of small pelagic fish species since they are preferred by poor households.

Sumber daya ikan di perairan Indonesia merupakan salah satu modal menuju kemakmuran bagi bangsa, apabila dikelola secara berkelanjutan.Kajian potensi dan tingkat pemanfaatan tahun 2015, merupakan salah satu dasar utama dalam merumuskan pengelolaan tersebut menuju pemanfaatan sumber daya yang lestari bagi kesejahteraan bangsa. Secara keseluruhan komposisi jenis sumber daya ikan di perairan Indonesia didominasi kelompok ikan pelagis kecil sebesar 36 % dan ikan pelagis besar sebesar 25 %. Potensi sumber daya ikan di perairan Indonesia adalah sebesar 9,931 juta ton per tahun dengan potensi tertinggi terdapat di WPP 718 (Laut Arafura) sebesar 1,992 juta ton/tahun (20%), di WPP 572 (Samudera Hindia sebelah barat Sumatera dan Selat Sunda) sebesar 1,228 juta/tahun (12 %) dan di WPP 711 (Selat Karimata, Laut Natuna dan Laut Cina Selatan) sebesar 1,143 juta ton/tahun (12 %). Tingkat pemanfaatan secara keseluruhan terlihat didominasi kondisi overfishing (indikator warna merah) sekitar 49 %, diikuti kondisi fully-exploited (indkator warna kuning) sekitar 37 % dan kondisi moderat (indikator warna hijau) hanya 14 %. Kelompok ikan yang mengalami kondisi overfishing paling tinggi adalah kelompok udang Penaeid, lobster, kepiting dan rajungan, yang mencapai 63 % dari kondisi overfishing saat ini. Dalam perspektif yang demikian, opsi pengelolaan yang harus segera dilakukan adalah mengurangi jumlah upaya penangkapan pada WPP yang mengalami kondisi overfishing serta meningkatkan upaya pada WPP yang tingkat pemanfaatannya masih moderat dan fully exploited.Fish resources within Indonesian waters (i.e. teritorial and archipelagic waters) including Indonesian Economic Exclusive Zone if under sustainably management it would contribute a significant role as a source of nation welfare. Scientific advice on stock status and its exploitation rate are required as an input to support an apropriate fisheries management. Generally, fish resources in these waters are dominated by two main fish groups such as small pelagic fish by 36 % and large pelagic fish by 25 %. Indonesia fish resource in 2015 was estimated for 9,931 million tons/year with comprises of 1,992 million ton/year (20 %) in fisheries management area (FMA) 718 (Arafura sea), 1,228 million/year (12 %) in FMA 572 (western of Sumatera of Indian ocean and Sunda strait) and 1,143 million tons/year (12 %) in FMA 711 (Karimata strait, Natuna sea, and south China sea). Most of fish resources (49 %) were in the status of overfishing with red indicator, folowed by fully-exploited state(37 %) in yellow indicator and only 14 % in the moderate state (green indicator). Among all nine fish groups, the overfishing state (up to 63%) is recorded from group of shrimps (Penaidae), lobster, and crabs. The management options in these prespective is urgently suggested to reduce fishing effort at the level of f.opt (fishing optimum) for overfishing fish groups. Whilts possibly to increase effort for fish groups with fully and moderate exploited state at the level off opt.

Distribution Of Fish

Nelayan penangkap ikan yang efektif membutuhkan informasi sumberdaya ikan dan pola penyebarannya. Penelitian ini bertujuan untuk mengetahui pola sebaran sumber daya ikan yang dikaitkan dengan kondisi oseanografi WPP-NRI 715. Analisis dilakukan berdasarkan kombinasi metode hidroakustik dan profiling CTD pada stasiun oseanografi yang dirancang secara parallel pada jarak tertentu di lintasan tersebut. Hasil penelitian menunjukkan, estimasi ukuran ikan pelagis yang terdeteksi didominasi oleh ukuran kecil. Ikan pelagis kecil yang terdeteksi didominasi ukuran ikan antara 12-14 cm dan ikan pelagis besar ukuran ikan 28-31 cm. Kepadatan ikan pelagis kecil cenderung menurun dengan rerata faktor 0,4 dengan bertambahnya kedalaman, sebaliknya meningkat dengan rerata faktor 1,7 untuk ikan pelagis besar. Pada saat observasi, dikawasan perairan Laut Maluku bagian timur diindikasikan terjadinya upwelling ditandai dengan suhu rendah, salinitas tinggi, dan klorofil tinggi. Ikan pelagis besar lebih banyak ditemukan pada lokasi yang memiliki karakteristik suhu dan DO yang relatif lebih tinggi sedangkan salinitas lebih rendah dibandingkan dengan lapisan air yang didominasi ikan pelagis kecil. Informasi pola sebaran ikan pelagis ini diharapkan dapat dijadikan rujukan bagi pelaku perikanan tangkap dan masukan untuk bahan perumusan kebijakan pengelolaan perikanan tangkap yang berkelanjutan.Effective commercial fishers need information on fish resources and their distribution pattern. This study aims to determine distribution of fish resources in Indonesian FMA 715 through tracking hydroacoustic method and CTD profiling at stations within regular distances. The results showed that the estimated size of pelagic fish was dominated by small size fish groups. Small pelagic fish were detected at the size ranged between 12-14 cm and large pelagic fish was dominated by the size of 28-31cm. The density of small pelagic fish decreases with depth with average factor of 0.4, while the large pelagic fish with average factor of 1.7.  An indicated upwelling incidence was likely occurred in the eastern part of Mollucas sea region, which were characterized by the low temperature, high salinity and high chlorophyll concentrations. Large pelagic fish were more occasionally found in locations with relatively higher temperature, DO characteristics and lower salinity compared with small pelagic fish. Information on the distribution pattern of pelagic fish is expected to be used as a reference for capture fishermen and inputs in formulating the policy the sustainable fisheries management.

Mesoscale Structures

This work develops a new method, the box-balance model (BBM), to assess the role of hydrodynamic structures in the survival of fish larvae. The BBM was applied in the northwest Mediterranean to field data, on 2 small pelagic fish species whose larvae coexist in summer: Engraulis encrasicolus, a dominant species, and Sardinella aurita, which is expanding northwards in relation to sea warming. The BBM allows one to quantify the contribution of circulation, with significant mesoscale activity, to the survival of fish larvae, clearly separating the effect of transport from biological factors. It is based on comparing the larval abundances at age found in local target areas, associated with the mesoscale structures (boxes), to those predicted by the overall mortality rate of the population in the region. The application of the BBM reveals that dispersion/retention by hydrodynamic structures favours the survival of E. encrasicolus larvae. In addition, since larval growth and mortality rates of the species are required parameters for application of the BBM, we present their estimates for S. aurita in the region for the first time. Although growth and mortality rates found for S. aurita are both higher than for E. encrasicolus, their combined effect confers a lower survival to S. aurita larvae. Thus, although the warming trend in the region would contribute to the expansion of the fast-growing species S. aurita, we can confirm that E. encrasicolus is well established, with a better adapted survival strategy.

This research was taken in Ambon (Latuhalat and Laha) and in Central Maluku Regency (Waai) in May – July 2018. It was aimed at mapping the value chain of small pelagic fish in Ambon through: 1) mapping of product, financial and information flows and 2). analysis of percentage distribution of small pelagic fish caught. The data used in this study was primary and secondary data, and analyzed by using value chain analysis. The results show that small pelagic fish marketing chain in Ambon consisted of six models with five actors. Each chain is formed due to the conditions and situation of market, resulted by the influencing of catches of fishermen and traders' capital. The broker plays an important role in marketing small pelagic fish in the market and obtaining 10% of the fishermen's catch that can be distributed, both to retailers and cold storage. Fish caught by the fishermen is still fresh in general when arrives in the consumers, because the fishing area is not too far, the market distance with the production centers is also quite close and in general fishermen and traders have understood the importance of maintaining product quality. Even so, the role of the Government in providing marketing facilities and infrastructure is needed so that modern market conditions can be applied in marketing fresh fish in Ambon.
