Perikanan teri berkembang sangat pesat khususnya di perairan utara Jawa Madura pada tahun terakhir ini. Kajian tentang karakteristik perikanan teri (Engraulidae) di sepanjang pantai utara Jawa-Madura dilaksanakan pada tahun 2017-2018, meliputi sebaran usaha perikanan, tipe armada-alat penangkapan ikan, aspek operasional penangkapan, hasil tangkapan-kelimpahan dan musim penangkapan ikan teri. Pengumpulan data pendaratan ikan teri dilakukan melalui survey di 11 lokasi pendaratan ikan. Hasil penelitian menunjukkan terdapat 12 lokasi tempat pendaratan utama ikan teri di sepanjang pantai utara (pantura) Jawa dan Madura. Dua jenis alat dominan digunakan untuk penangkapan teri adalah pukat cincin dan payang; perikanan bersifat skala kecil, melakukan trip harian, dengan armada kapal penangkap berukuran dibawah 20 GT. Jaring umumnya menggunakan waring dengan mata jaring kecil (3/8 inch) di bagian kantong. Daerah penangkapan di perairan pantai yang dangkal, dekat dengan basis perikanan. Musim penangkapan ikan teri bervariasi, di wilayah bagian barat (Pulolampes, Larangan, Morodemak) berlangsung sekitar musim timur/tenggara (Mei Juli), sedangkan di wilayah bagian timur berlangsung pada awal musim timur dan berjalan cukup lama hingga bulan November (musim peralihan 2). Hasil tangkapan per unit upaya (CPUE, sebagai indek kelimpahan) diduga makin ke arah timur semakin rendah namun disertai musim penangkapan ikan lebih lama. Anchovy fishery has grown rapidly, especially in the northern waters of Java-Madura in the last year. The study on the characteristics of the anchovy fishery (Engraulidae) along the northern coast of Java-Madura was carried out in 2017-2018, covering the distribution of fisheries effort, types of fishing gear, operational aspects of fishing, catch-abundance and fishing season. The collection of anchovy landing data was carried out through a survey at 11 fish landing sites. The results showed that there were 12 main anchovy landing sites along the north coast (pantura) of Java and Madura. Two types of dominant fishing gear used for anchovies are purse seine and payang; Fisheries are small-scale, undertaking daily trips, with a fleet of fishing vessels under 20 GT. The nets generally use “waring” with small mesh (3/8 inch) in the codend. Fishing area in shallow coastal waters, close to the fishing base. The fishing season for anchovy varies, in the western region (Pulolampes, Larangan, Morodemak) it takes place around the east / southeast season (May-July), while in the eastern region it takes place at the beginning of the eastern season and lasts quite a long time until November (transition season 2) . The catch per unit effort (CPUE, as an abundance index) is thought to be getting lower eastward but accompanied by a longer fishing season.

Salah satu alasan yang kuat nelayan tangkap skala kecil tetap melaut meskipun mempunyai risiko tinggi karena peluang/prospek pendapatan/penerimaan yang tinggi pada satu saat. Risiko melaut tidak hanya membuat ketidakpastian tetapi juga karena risiko biaya operasional yang tinggi. Dihadapkan dengan kondisi biaya operasional yang  tinggi, nelayan menggunakan strategi yang berbeda, salah satunya melekat pada peran tengkulak. Dalam pandangan konvensional, pedagang perantara/ langgan sebagai hambatan bagi nelayan untuk menjadi kompetitif di pasar. Namun di negara berkembang seperti Indonesia, mereka memainkan peran penting sebagai "bantal sosial" dalam kehidupan nelayan skala kecil. Tujuan penelitian adalah menyelidiki tingkat kecenderungan keterikatan hubungan langgan/pedagang antara sebagai “bantal sosial” dengan nelayan di dua daerah penangkapan ikan yang menonjol di pantai utara dan pantai selatan Jawa. Analisis data dilakukan dengan metode analisis kuantitatif yaitu model analisis multinomial logistik. Hasil penelitian menunjukkan bahwa nelayan dari pantai utara cenderung sangat kuat hubungannya dengan perantara untuk kelangsungan hidupnya dibandingkan dengan nelayan di pantai selatan. Implikasi dari temuan tersebut bahwa peran sentral langgan/perantara/tengkulak/langgan merupakan bentuk hubungan yang bersifat ekonomi dimana kedua belah pihak bisa mengambil keuntungan. Pola hubungan bukan hanya sekedar sebagai penyangga, namun lebih dari itu yaitu berfungsi sebagai “bantal” sosial (social cushion) para nelayan. Hubungan seperti ini merupakan bentuk layanan dimana para nelayan bisa mendapatkan alternatif layanan jasa “kredit” dari para perantara/langgan/tengkulak. Bentuk layanan seperti yang diperankan oleh langgan/pedagang perantara selama ini belum bisa digantikan oleh lembaga pemerintah yang resmi, dimana pola hubungan tersebut sangat dibutuhkan oleh nelayan skala kecil. Pola hubungan tersebut selain dipengaruhi oleh lokasi, juga dipengaruhi oleh status kepemilikan kapal, lama kepemilikan kapal dan jumlah ABK.Title: The Role “Social Cushion” On The Livelihood Of Small Scale Fishers In JavaOne of the strong reason for small scale fishers to keep fishing despite high risk of fishing, is the prospect of high earning at one moment in time. Risk at fishery not only  create uncertaining but also risk high cost of fishing. Faced with such a high cost, fishers use different strategies, one of which is attached to the middlemen. Convientional views middlemen as an obstacle for fishers to be competitive in the market. Yet in developing country such us Indonesia, they play crucial role as a “social cushion” in the livelihood of small scale fishers. The purpose of research is to investigate the tendency of engagement relationships middleman as "social cushion" with fishermen in the fishing areas that stand out on the north coast and the south coast of Java. Data was analyzed using quantitative analysis method multinomial logistic analysis model. Results of this study show that fishers of the northern coast tend to strongly attach to middlemen for their survival compared with those in the southern coast.  Relationships with fishermen middlemen is a service, where fishermen can get alternative services "credit" from the middleman. Services such as that played by middleman has not been able to replace them by official government agencies, where this kind of relationship is needed by small-scale fishermen. The relationship patterns in addition affected by the location, also influenced by the status of ownership of the vessel, long time ship ownership and the number of crew.

<p><em>The existence of the coast in the northern part of Karawang Regency is very worrying. Seawater<strong> </strong>that was far up to tens of meters from the side of the road, is now on the lip of the road, even some parts of the road are cut off due to abrasion of seawater. Some villages were affected by abrasion erosion. One of the effects of damage due to abrasion and sedimentation is the occurrence of shoreline changes. This change in coastline will affect people's lives and spatial planning for the development of the area. For this reason, this study aims to determine the extent and rate of shoreline changes that occurred on the coast of Karawang Regency in the periods of 1989, 1995, 2001, 2005, 2009, 2016, and 2018. The shoreline data was obtained from the extraction of Landsat 3 MSS, Landsat 5 TM, Landsat 7 ETM +, and Landsat 8 </em><em>OLI</em>-<em>TIRS after the NDWI process was previously carried out. While the rate of change is calculated at 6 sample point locations scattered along the northern coast of Karawang Regency. The results showed that the largest area damaged by abrasion occurred in Sedari Village covering an area of 166.802 hectares, and the area formed by the largest sedimentation occurred in Muara Cilamaya Village at 276,318 hectares. Meanwhile, the fastest rate of shoreline change due to abrasion occurred in Sukajaya Village at 10 meters </em>/<em>year, while the slowest in Sedari Village at 3.77 meters / year. The fastest sedimentation process in Muara Cimalaya Village is 4.5 meters / year, while the late one in Tanjung Pakis Village is 3.09 meters / year.</em><em></em></p><p><strong><em>Keywords: </em></strong><em>Abra</em><em>sion, Accretion, Coastline Changes, Karawang</em><em></em></p>

Demak is a coastal area on the North Coast of Java with a large enough potential for demersal fish resources. This research aimed to determine the composition, the length and weight distribution, and catch per unit effort (CPUE) of demersal fish caught using mini bottom trawl at the north coast of Demak Regency. The research was carried out in October-December 2020 by observation of ten trips of mini bottom trawl fishing. Each fish captured was then grouped by type, identified, and measured its length and weight. The result showed that 38 species consist of 31 fishes, four mollusks, and three crustaceans. The fish captured dominated by pony fish (Leiognathus equulus) as much as 31.23% and largehead hairtail (Trichiurus lepturus) of 23.52%. The catch per unit effort (CPUE) average of mini bottom trawl was 44.77 kg/trip. Mainly fish (more than 95%) caught in small size compared it’s the maximum attainable length (L-max), with all the weight ranges from 0.3 to 520 g and more than 98% sized 0.3-80 g. Mini bottom trawl catches many types of fish and small size; therefore, mini bottom trawl is classified as a type of fishing gear with a very low selectivity level.

Blood profiles were determined in 47 juvenile green turtles, Chelonia mydas, from São Paulo northern coast, Brazil. Twenty-nine were affected by fibropapillomas and 18 were tumor free. Complete gross and histopathologic examinations of the fibropapillo were performed in 21 green turtles. Biometrical data, size, location and amount of tumors were recorded. The papillomas varied in morphology, location, size, color and texture. We found hyperplastic stroma, rich in blood vessels and connective tissue with increase in thickness of the dermis. The tumors w0ere classified as papillomas or fibropapillomas according to their epithelial and/or stromal proliferation. The lowest Mean Corpuscular Hemoglobin (HCM) values were observed in affected turtles.

Excavations at the small-scale domestic settlement of Gramalote between 2010 and 2014 allowed the exploration of the social dynamics and economic interactions in the second millennium BC on the Peruvian North Coast. Detailed excavations and materials recovered during the intervention contribute a unique opportunity to explore domestic aspects of early settlements in the Andes. This study presents new data on the public sectors of Gramalote's settlement, house-to-house differences, and evidence that the extended family was a unit of economic productivity and collective action. This analysis assesses the degree of overlap, and lack thereof, in the economic activities of each house during the Initial Period (1500–1200 cal BC). A new model for social and economic interactions is proposed, with the aim of exploring alternative models from the bottom-up perspective for the emergence and consolidation of social complexity in the Central Andean Region.

A 1977 exploratory survey of subtidal clam resources in the southeastern Bering Sea revealed extensive concentrations of Alaska surf clams (Spisula polynyma) along the north coast of the Alaska Peninsula. Using east coast hydraulic clam harvesters, subsequent 1977 and 1978 stock assessment surveys delineated a geographically isolated stock with an estimated exploitable biomass of 329 000 ± 52 000 t and conservatively calculated potential annual yield of 25 017 t (maximum sustainable yield) of whole clams. Production fishing trials at 13 sites in 1978 produced an average catch per unit effort of 815 kg/h with a 1.84-m-wide clam harvester.Life history studies indicated the species is long-lived (25 yr), slow growing (K = 0.135), fully recruited to the spawning population at 8 yr of age, subject to low natural mortality (conservatively calculated as M = 0.19), and attains maximum cohort biomass at ages between 9.4 and 13.0 yr. Biological rationale for management measures is presented.Key words: population assessment, sustained yield, surf clams, Alaska

Fisheries Interactions

Conflict between dolphins and fisheries is an important management issue in many parts of the world. In 2002, we examined the extent of depredation in the Italian small scale fishery by means of in situ interviews. Overall, 245 landing sites were investigated, representing 11.09% of the whole Italian artisanal fleet. The association between the commonly used artisanal fishing gear and the interacting fauna was investigated by means of correspondence analysis. Set gillnet and trammel nets were the types of the fishing gear most vulnerable to dolphin depredation; the interaction with these gear amounted to 66.4% while fish damage was reported in 72.2% of the cases. A regional ranking of the interactions in terms of both fishing gear alteration and fish damage, shows that the problem is most pressing in the Friuli, Campania, Sardinia and Apulia regions. This study is the first attempt to monitor dolphin–fisheries interactions and assess depredation rates in Italy, providing information on the areas where future investigation should be concentrated.

The Status

Fisheries in Semarang City are dominated by small-scale fisheries. This is indicated by the use of the largest fishing fleet of 10 gross tons operating near the coast. This study aims to analyze the status of small-scale fisheries in Semarang City for sustainable management. Sustainable management is management that guarantees the availability of natural resources and environmental services for future generations. The study was conducted for three months, namely September-November 2018 in the coastal waters of Semarang City, which was part of the Fisheries Management Region (WPP) 712. The method used in this study is the analysis of time series surplus production, namely data from the catch (ton/year) and the number of fishing gear (unit) within 10 years (2007-2016), to calculate the catch per-unit effort (CPUE), maximum sustainable yield (MSY), optimum effort (fopt), utilization rate (TP) and capacity level (TK). This study was obtained results of a downward trend in CPUE; the existing fishery catch or production in 2016 has exceeded the MSY value is 479 tons/year (Schaefer) and 439.11 tons/year (Fox); utilization rate of more than 100% which is 108-127% (Schaefer) and 118-138% (Fox), so that small-scale fisheries in Semarang City are at the level of over-exploited. Based on the fopt analysis, the number of fishing gear used (fexisting) has exceeded the optimum effort with a fishing capacity exceeding 100%, so that small-scale fisheries in Semarang City have experienced overcapacity.
