A methodology had been proposed for cross-matching visible infrared imaging radiometer suite (VIIRS) boat detections (VBD) with vessel monitoring system (VMS) tracks. The process involves predicting the probable location of VMS vessels at the time of each VIIRS data collection with an orbital model. Thirty-two months of Indonesian VMS data was segmented into fishing and transit activity types and then cross-matched with the VBD record. If a VBD record is found within 700 m and 5 s of the predicted location, it is marked as a match. The cross-matching indicates that 96% of the matches occur while the vessel is fishing. Small pelagic purse seiners account for 27% of the matches. Other gear types with high match rates include hand line tuna, squid dip net, squid jigging, and large pelagic purse seiners. Low match rates were found for gillnet, trawlers, and long line tuna. There is an indication that VMS vessels using submersible lights can be identified based on consistently low average radiances and match rates under 45%. Overall, VBD numbers exceed VMS vessel numbers in Indonesia by a nine to one ratio, indicating that VIIRS detects large numbers of fishing boats under the 30 Gross Tonnage (GT) level set for the VMS requirement. The cross-matching could be used to identify “dark” vessels that lack automatic identification system (AIS) or VMS.

Blue swimming crab (Portunus pelagicus) is an important economical fishery commodity for fishermen in Banten Bay that are caught using gill nets and collapsible traps. The increasing of fishing pressure has highly potential to reduce the quality of the catch as exposed in previous studies. However, the comprehensive, and time series analysis of the previous research results have not been conducted. The purpose of this study is to analyze the variations of blue swimming crab caught in Banten Bay through a combination of meta-analysis techniques, fishing trials and field obser-vations to determine the effect of fishing activities on swimming crab sizes, and evaluate the status of swimming crab fisheries in Banten Bay. Standard mean difference from 10 different studies was used as a meta-analysis parameter. The results of the meta-analysis showed that fishing activities were conducted from 2004 to 2018 had a significant effect on the decreasing of the swimming crab size. The average of swimming crab carapace width caught in 2019 approximately 121.66 mm. The proportion of legal swimming crabs in 2014, 2015 and 2019 was more than 80%, so that the status of swimming crab fisheries in Banten Bay is still environmentally friendly.Keywords: carapace width, meta analysis, fisheries, Portunus pelagicus, blue swimming crab

Fixed lift net fisheries in Banten Bay used compact fluorescent lamp (CFL) since the middle of 2000 for replacement the traditional pressured kerosene lantern. It was increased the light intensity, but this lamps consumed high energy and fuels. Application of light emitting diode (LED) is considered to energy saving and increased catches in lift net fisheries. The fishing trial was conducted on 22 M ay -16 June 2015 in Banten Bay Indonesia using 2 units of lift net with 6 units of CFL and LED respectively. The result shows both lamps did not have significant effect on total catches. M eanwhile, application of LED lamps has significant effect to main catch (anchovy). There were increasing catch weight of anchovy with mean 29.49%. LED also decreased of fuel consumption with mean saving 35.15%. It is evident enough to conclude that LED lamps have high efficiency and effectiveness for lift net fishing in Banten Bay.

<p align="center"><strong><em>ABSTRACT</em></strong></p><p><em>Fishing activity using light emitting diode (LED) on </em><em>a </em><em>fixed lift net in Banten Bay is </em><em>equipped </em><em>using blue and white LED as its attractor.</em><em> </em><em>The colour and intensity of the lighting affects the successful capture of the lift nets.</em><em> </em><em>The colour selection is influenced by the interaction of the fish as the target.</em><em> </em><em>The objective of this study is to determine the optimum colo</em><em>u</em><em>r and intensity for Yellowstripe Scad (Selaroides leptolepis) based on their behavioural response and light adaptation to different colours of green and white at three different intensities which are low (1.53 x 10^-5 – 2.42 x 10^-5 W/cm²), medium (5.39 x 10^-5 – 7.60 x 10^-5 W/cm²), and high (9.03 x 10^-5 – 9.42 x 10^-5 W/cm²)</em><em>. </em><em>The behavioural response of </em><em>the </em><em>fish was conducted using a tank experiment to measure the preferences zone, </em><em>the </em><em>nearest neighbour distance (NND), and behavioural response pattern </em><em>for</em><em> different colours and light intensity.  Histological approach for each experimental light colour and intensity was used to investigate the retinal adaptations. The results showed</em><em> that</em><em> the schooling position of fish was dominant found in the bright zone (67%) for all colours and intensities.</em><em> </em><em>The average NND showed the tendency to gradually decrease </em><em>with the </em><em>increased light intensity. While, the cell cone index and swimming speed of fish were slightly increased with increasing intensity.</em><em> </em><em>The highest light adaptation was found in white LED at high intensity about 97.52%.</em><em> </em><em>The schooling pattern in the green LED indicated that the fish gradually swam closely and stable regularly to the neighbour with increasing light intensity. However, the fish swam widely and randomly in accordance </em><em>to the</em><em> increased white LED intensity. This information suggests that the green LED may be regarded as an excellent fishing light to control the behaviour in order to harvest the yellow stripe scad in lift net fishing.</em></p><p><strong><em>Keywords</em></strong><em>: colour, lift net, light, yellowstripe scad</em><em></em></p><p align="center"><strong> </strong></p><p align="center"><strong>ABSTRAK</strong></p><p>Efisiensi aktivitas penangkapan ikan dengan menggunakan bagan tancap sangat ditentukan oleh penggunaan cahaya sebagai atraktornya. Ketepatan warna dan intensitas cahaya sangat menentukan keberhasilan operasional bagan tancap.  Penetapan warna dan intensitas cahaya yang tepat sangat dipengaruhi oleh respon yang dihasilkan oleh ikan target. Oleh karena itu, penelitian ini bertujuan untuk menentukan warna dan intensitas cahaya lampu LED yang optimum untuk penangkapan ikan selar (<em>Selaroides leptolepis</em>) berdasarkan respons tingkah laku dan adaptasinya terhadap warna dan intensitas cahaya yang berbeda. Penelitian dilakukan secara eksperimental di perairan Teluk Banten dengan target penangkapan adalah ikan selar (<em>Selaroides leptolepis</em>). Penelitian dilakukan dengan menggunakan dua kelompok perlakuan yaitu warna dan intensitas cahaya. Perlakuan warna adalah dengan menggunakan lampu LED berwarna hijau dan putih. Adapun perlakuan intensitas cahaya adalah dengan menggunakan tiga intensitas cahaya yaitu intensitas rendah 1,53 x 10^-5 – 2,42 x 10^-5 W/cm²; sedang 5,39 x 10^-5 – 7,60 x 10^-5 W/cm²; tinggi 9,03 x 10^-5 – 9,42 x 10^-5 W/cm². Penelitian dilakukan dengan melakukan pengamatan terhadap respon ikan target dari famili Engraulidae dan Carangidae. Pengamatan respons tingkah laku dilakukan pada bak pengamatan untuk menentukan zona preferensi, <em>nearest neighbor distance</em> (NND) dan pola tingkah laku ikan terhadap warna dan intensitas berbeda. Adaptasi retina dianalisis secara histologi berdasarkan warna dan intensitas yang berbeda. Berdasarkan hasil penelitian posisi <em>schooling </em>ikan dominan berada pada zona terang (67%) pada seluruh warna dan intensitas lampu LED. Nilai NND cenderung turun seiring dengan peningkatan intensitas cahaya, sedangkan indeks kon dan kecepatan renang semakin tinggi dengan penambahan intensitas cahaya yang diberikan. Nilai adaptasi tertinggi diperoleh pada penggunaan lampu LED putih dengan intensitas tinggi sebesar 97,52%. Pola tingkah laku ikan pada LED hijau semakin teratur dengan jarak semakin dekat seiring meningkatnya intensitas. Namun pola renang ikan cenderung acak dan semakin jauh pada LED putih. Hasil penelitian mengindikasikan bahwa LED hijau lebih optimum untuk digunakan sebagai lampu pengumpul, pengkonsentrasi dan <em>hauling</em> pada penangkapan ikan selar dengan bagan tancap.</p><strong>Kata kunci</strong>: bagan, cahaya, warna, ikan selar (<em>Selaroides leptolepis</em>)

Food availability is the first step to ensure the food access and the food utilization, to realize the food security in Banten Province. One sector that can play a role in supplying animal food is the capture fisheries sector. The capture fisheries sector contributes around 50% of the fish production in Banten Province. However, the level of fish consumption of Banten societies is relatively lower compared to eastern Indonesia region. This paper outlines a comparative descriptive analysis of the opportunities and roles of the capture fisheries sector in supporting the realization of food security in Banten Province.
