This study aims to analyze the large income disparity in coastal and non-coastal areas in Banten Province and to analyze whether the fisheries sub-sector has become the economic base in Banten Province in 2015 – 2019. January until May 2021. The method is carried out by survey method then analyzed quantitatively and presented descriptively. The data of this study were sourced from secondary data and primary data. Data were obtained from BPS Banten Province, BPS West Java Province, Marine and Fisheries Service Banten Province, Marine and Fisheries Service West Java Province and through questionnaires from coastal and non-coastal communities. Data analysis includes analysis of Williamson index, Gini coefficient and Location Quotient (LQ). based on the results of research conducted, it can be concluded that the income disparity in the coastal areas of Banten Province is greater than in the non-coastal areas. The Gini ratio analysis shows that the value of the Gini ratio has decreased from year to year, which means that income distribution is more evenly distributed until in 2019 it reaches 0. The fisheries sector in Banten Province is included in the non-base sector because it has a value of 0.5671. Production of catch commodities that get superior commodities: small pelagic fish group (mean LQ=1.81) and demersal fish group (mean LQ=0.84).

Fish Harvest

Despite the magnitude of domestic and industrial pollution, fishery yield registered in several landing points at Guanabara Bay, between April 2001 and March 2002 was slightly over 19,000 tons, corresponding to a value of US$ 4.8 million. When considered only the fish directed to the food market, the total catch amounted to about 6,300 tons and a value of US$ 3.7 million. Only a few fish species reached expressive densities compatible with commercial fisheries. Among small pelagic fish, Atlantic anchoveta and Brazilian sardinella were the dominant species, while in terms of demersal fish, croakers, mullets and catfishes comprised the main part of the catch. The absence of landing data previous to the spilling of 1.3 million liters of oil in January 2000 led to claims by fishermen representative organizations of values corresponding to about 50 years of fish harvest in the bay. Possibly, a data collection network could be established in a participative way with the main fishermen local associations. The relatively stabilized fisheries in the bay suggested that reasonable inferences could be made, without, necessarily having a complete coverage of all landing points.

Pelagic Fishing

This study aims to analyze the economic value of small pelagic fishing fisheries in Indramayu Regency, West Java. This research was conducted by a survey method using a questionnaire with a purposive sampling method and the data were analyzed descriptively quantitative and qualitative. The benefits of the results of this study are expected to provide information for decision making for the relevant government in formulating policies on fisheries activities, especially small pelagic fish in Indramayu Regency West Java so that they remain sustainable. Catching small pelagic fish is done by purse seine, mini purse seine, Millenium gill net, fishing line, and nylon net. The majority of the ship size used ships with sizes below 20 Gross Tonnage (GT). The types of small pelagic fish caught are Anchovy, Mackerel, Long Jawed Mackerel, Sardine, Scad, Sand Whiting, Tanjan Fish, Rucah Fish and Japuh Fish. The highest acceptance value of small pelagic fish in 2019 is found in anchovies, which is 8.997 billion. So that the highest profit of the highest small pelagic fish obtained in 2019 is found in Anchovy, amounting to 8,780 billion. The Benefit-Cost Ratio (BCR) calculation shows that the BCR value for catching pelagic fish species above is> 1 so that the fishing activity is feasible and can be continued. 99.7% of small pelagic fishing activities are influenced by the GT of the ship, the number of trips (months), and the fishing gear based on the calculation of multiple linear regression analysis.

Payang merupakan alat tangkap dengan laju tangkap relatif tinggi di Teluk Jakarta, sedangkan bagan tancap dikenal kurang selektif karena hasil tangkapannya didominasi oleh ikan berukuran kecil baik jenis pelagis maupun demersal. Penelitian ini dilaksanakan dengan metode fishing experiment pada payang dan bagan tancap. Hasil penelitian menunjukkan bahwa hasil tangkapan payang dan bagan tancap didominasi oleh jenis ikan demersal namun proporsi tangkapannya tidak jauh berbeda dengan jenis ikan pelagis. Komposisi ikan hasil tangkapan payang pada Agustus dan Oktober didominasi oleh jenis ikan pelagis, sedangkan pada bulan Desember didominasi oleh jenis ikan demersal. Nilai laju tangkap payang untuk jenis ikan pelagis ditemukan tinggi pada Agustus dan Oktober disebabkan oleh dominasi ikan cekong (Sardinella lemuru) dalam jumlah besar. Komposisi ikan hasil tangkapan bagan tancap pada Mei didominasi oleh jenis ikan demersal, sedangkan pada Oktober didominasi oleh jenis ikan pelagis. Daerah penangkapan payang meliputi perairan Pulau Damar, Pulau Bendera, Muara Pecah, Muara Angke, Pulau Onrust, Pulau Putri, Kronjo, sedangkan daerah penangkapan bagan tancap terkonsentrasi di sebelah barat perairan Teluk Jakarta, sekitar Pulau Kayangan, Pulau Bidadari dan Pulau Onrust.   ABSTRACT Payang, a mini danish seine, is an artisanal fishing gear that has high catchability rate. Like payang, another dominant fishing gear in Jakarta Bay, the lift net, is also known as unselective fishing gear since small fish dominate its catch. This research uses the fishing experiment method with payang and lift net to figure out the gears' catch composition and catch rate. The result shows both fishing gears predominately caught the demersal fish group, but its proportion does not much from the pelagic group. During August and October, the catch composition of payang was dominated by pelagic fish, while demersal fish was caught mostly in December. The high catch rate for pelagic fish was recorded in August and October since cekong fish (Sardinella lemuru) dominated the cath. The catch composition of lift net was dominated by demersal fish during May, while pelagic fish were mostly captured in October. Payang’s fishing ground includes Pulau Damar waters, Pulau Bendera, Muara Pecah, Muara Angke, Pulau Onrust, Pulau Putri, and Kronjo, while the lift net dominates the western part of part of Jakarta Bay including Pulau Kayangan, Pulau Bidadari, and Pulau Onrust.

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.
