Abstract

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. Intensitas dan warna yang digunakan harus disesuaikan dengan preferensi, respons dan tingkah laku ikan target sehingga ikan lebih cepat terkumpul dan terkonsentrasi pada catchable area. 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. Ikan uji diperoleh dari hasil tangkapan sero yang berada di sekitar wahana penelitian. Data respons dan tingkah laku ikan terhadap lampu neon, LED biru, hijau dan putih direkam menggunakan sonar 360° dan side imaging sonar. Hasil penelitian menunjukkan LED hijau memiliki efektivitas yang lebih baik dalam memikat, mengumpulkan dan mengkonsentrasikan ikan pada main zone dibandingkan jenis lampu lainnya. Ikan lebih cepat berkumpul, membentuk kelompok serta memiliki pola renang yang stabil dan konsistem di zona utama pencahayaan. LED hijau lebih tepat digunakan sebagai fishing lamp pada bagan tancap dibandingkan jenis lampu lainnya dengan intensitas optimum antara 4-20 μW/cm².Kata kunci: Cahaya, Intensitas, Optimum, Respons, Tingkah laku

Abstract

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
