Pot fisheries are one of the dominant activities of capture fisheries in the Penaah waters of Lingga, Riau Archipelago. This study aims to determine the effect of red LED lamp attractors on the fish catches of pots and identify the fish species. This study was conducted in the waters of Pena'ah Village, Senayang District, Lingga Regency, Riau Islands, using an experimental method. Data were collected from 18 pots for 18 days. There were three treatments, namely pot without using bait as a control, pot with red LEDs light, and pot with red LEDs light and bait, in which a total of six units of pots on each treatment. The pots caught 18 groupers during the study, of which nine individuals were captured by the pot with a red LED and bait, five individuals by the pot with a red LED pot, and four individuals without bait. The effectiveness analysis showed that the pot with red LED and bait was the highest (50%), the pot with red LED had a value of 28%, and the lowest was trapped without bait with an effectiveness value of 22%. The total catches of the pot based on the economic fish showed that adding a red LED attractor gave more types of catch than control. The red LED attractor is expected to be a solution to increase the effectiveness of the pot.

The effectiveness of the artificial lights on fishing activity with a fixed lift net is significant influences on the success of fishing operations. The used of color and intensity must be adjusted to the preferences, response and behavior of the target fish, due to the fish can be more quickly attracted and concentrated in the catchable area. The development of LED technology as an energy-saving lamp has a great opportunity to be applied as a fishing lamp for fixed lift net fisheries. The purpose of this study is to determine the effectiveness of low power LEDs as a fishing lamp based on fish behavioral response. The study was conducted on a research field laboratory that was built in the waters of the Banten Bay in July - August 2018. Test fish were collected from catches of the guiding barrier around the research vehicle. Data on response and behavior of fish to fluorescent lights, blue, green and white LEDs were recorded using 360 ° sonar and side imaging sonar. The results showed the green LEDs had better effectiveness in attracting, focusing and concentrating fish in the main zone than other types of lights. The fish gather more quickly, form groups and have a stable and consistent swimming pattern in the main lighting zone. Green LED is more appropriate to be used as a fishing lamp on fixed lift net fishing with an optimum intensity range of 4-20 μW cm².Keywords: Light, Intensity, Optimum, Response, BehaviorABSTRAKEfektivitas lampu yang digunakan pada proses penangkapan dengan bagan tancap sangat berpengaruh terhadap keberhasilan operasi penangkapan ikan.

Perkembangan teknologi LED sebagai lampu hemat energi berpeluang besar digunakan sebagai fishing lamp untuk perikanan bagan tancap. Penelitian ini bertujuan untuk menentukan efektivitas low power LED sebagai lampu pemikat ikan berdasarkan aspek respons dan tingkah laku ikan. Penelitian dilakukan pada wahana penelitian yang dibangun di perairan Teluk Banten pada bulan Juli - Agustus 2018.

Blue swimming crab (Portunus pelagicus) is the dominant catch in Betahwalang, Demak, and the most important export fish commodity, particularly to USA. The high demand for this crab has been promoting an excessive fishing effort, causing a decrease in the crab's natural stock. This study aims to investigate the biological condition of P. pelagicus on the northern coast of Central Java and assess the crab stock exploitation status in this study area. Carapace width, body weight, Gonad Maturity Stages (GMS), and sex of crab samples were collected from the fishers and collectors landing sites or meeting points. This study employs a simple random sampling technique with no replacement. This study revealed that the maximum carapace width of female crabs was 56-164 mm, and the estimated carapace width at first maturity (Lm) was 98.2 mm. The relationships between carapace width and body weight between male and female crabs indicated positive and negative allometric growth patterns. During this assessment, the P. pelagicus stock indicated an 'over-exploited’ status, with an LB-SPR parameter of 19 percent and an exploitation rate (E) of 0.66. Management measures such as minimum legal size, reduced effort, and open-close areas and seasons should be implemented to achieve sustainable use of the crab fishery.Keywords:Blue swimming crabFishing gearDemak watersCarapace lengthSpawning potential ratio

The response of eel fish (Anguilla bicolor) glass eel stadia to different light is fundamental knowledge for developing fishing methods and conserving fish resources. The study aimed to describe how glass eel fish react to different types of light. In the laboratory, glass eels were observed responding to red, blue, and white LED light versus no light as controls. Glass eels ranging in size from 4.0 to 6.1 cm and weighing up to 0.28 g were caught in the Pelabuhanratu estuary of the Cimandiri River. Observations were made for 31 days, beginning five days after the glass eel was captured. The Mann Whitney and Kruskal-Wallis tests were used to describe differences of the glass eel's response to light. Observations showed that glass eels responded more to dark zones with values above 80% when compared to zones given red, blue, and white LED light. The percentage of fish in red LED lights was 23±0.22% higher, with the number of fish on blue LED lights by 10±0.21% and white LED lights 8±0.15% (p<0.05, Kruskal-Wallis). The difference in response to light can be used for glass eel catching applications, especially lamps for eel fish aids and eel conservation to create fishing zones and eels.Keywords: Anguilla bicolor, eel behavior, glass eel, LED light, response to light

The application of a fixed lift net using a Light Emitting Diode (LED-RGB) based on the Pulse Width Modulation (PWM) is one of the optimal fishing methods. The impact of the application of LED-RGB affects the catches in Banten Bay. The study aimed to identify the catches on fixed lift nets by using LED-RGB based on the PWM system. An experiment was direct data collection in Banten Bay, then the catch composition was analyzed by paired sample t-test with α 95% interval. The results showed that the number of catches on LED-RGB was significantly different from the number of catches on 4U fluorescent, while the types of catches were almost the same. The composition of fish species caught by LED-RGB was about 24 species and 4U fluorescent (22 species). The average percentage of fish species composition in LED-RGB lights was higher at 16,09% in Selaroides leptolepis species at 95 PWM intensity, compared to 4U fluorescent, the highest was Moolgarda seheli (13,27%).

Saat ini kegiatan budidaya sidat masih mengandalkan benih sidat (glass eel) dari alam dan muara Sungai Cimandiri menjadi salah satu lokasi penangkapan glass eel. Tujuan penelitian ini adalah menghitung produktivitas alat tangkap glass eel, mengidentifikasi hasil tangkapan dan menghitung pendapatan pengumpul glass eel di muara Sungai Cimandiri. Metode penelitian menggunakan metode kuantitatif dengan observasi langsung di lapangan menggunakan simple random sampling dan accidental sampling. Analisis data yang digunakan adalah analisis hasil tangkapan utama, analisis hasil tangkapan sampingan, dan analisis keuntungan. Hasil penelitian menunjukkan nilai CPUE muara Sungai Cimandiri tertinggi terjadi pada bulan Juli yaitu sebesar 37,1 gr/jam, terendah terjadi pada bulan September sebesar 1,6 gr/jam, sedangkan bulan Februari, Maret, Oktober, dan Desember tidak ada aktivitas penangkapan. Hasil tangkapan sampingan sebesar 20% dari hasil tangkapan total sebanyak 2995,6 gr yang terdiri dari, gere-gere (Microphis sp) 3%, udang merah (Metapenaeopsis sp) dan udang beras (Penaeus sp) 1%, boboso (Bunaka gyrinoides) 6%, kanayapan (Butis sp) 3%, kepiting batu (Clistocoeloma sp) 1%, tempang podol (Ambassis sp) 5%, dan belanak (Moolgarda seheli) 1%. Penerimaan usaha pengumpul sidat tahun 2019 sebesar Rp178.536.000 per tahun dan biaya usaha sebesar Rp157.524.400 per tahun, sehingga keuntungan yang didapat sebesar Rp21.011.600 per tahun.
