ABSTRACT The success of baited hook and line fishing gear is determined by the activity of fish in terms of finding and catching food. Adding shrimp extract on bait may increase the fishing power of the bait; but this kind of scientific information, particularly on the bottom hand line is not widely available. This study aimed to determine the effect of shrimp extracts on demersal fish catch in the surrounding fishing ground and to identify the species caught by the bottom hand line. This research was conducted in coastal waters Tateli Weru Village, District of Mandolang, Minahasa in October 2015 which was based on an experimental method. Six units of bottom hand line was operated, where three units using bait of scad mackerel marinated in shrimp extract, and three other units using plain bait of scad mackerel; and the data were analyzed using t-test. Total catches was 60 fish; 38 fish caught by bait with shrimp extract, and 22 fish caught by bait without shrimp extract. The results showed that use of bait with shrimp extract give more catches.

Abstract This paper aims to examine how to protect of artisanal fishermen fishing ground and the policies that protect them. Small-scale fisher fishing grounds has to have a special attention due to their limitation. They are using very simple fishing gear, so they can’t sail far away from the coastal waters. The Fishing law give a specific attention for this matter, by limiting fishermen with 5 gross tonnage (GT) are only able to conduct their activities within the coastal waters. This study combines legal documents and the results of interviews with fishermen on 5 GT vessel. this studi of find, then the Law Number 27/2016 changed this regulation by increasing gross tonnage for small-scale fishermen from 5 became 10 GT, and it attract more serious problems for these small-scale fishermen since they have no exclusive fishing ground anymore. It will also affect to changes of fishing lane; fishing ground and vessels authorization procedure. By increasing GT, the 10 GT vessels also have rights to sail in the same fishing ground with 5 GT vessels and it’s created a potential conflict between the fishermen. So, harmonization of law is important task for the government in avoiding the overlapping rules on vessels criteria, by choosing law that prioritize on small-scale GT vessels.

Abstract Research on the potential fishing ground for demersal fishing is a way to determine the areas that have the potential for fishing activities. Potential fishing ground mapping can be done by observing the dynamics of oceanographic parameters. The use of satellite imagery helps in providing oceanographic data in order to study the variability of oceanographic parameter. The aim of the study was to analyse the relationship between oceanographic parameter and demersal fish catch in order to validate potential fishing grounds for demersal fish. This research has been conducted in the waters of the Riau islands. Field observations and data collection including surveys of fishing grounds and identification of fish catches were carried out during March to August 2020. To support the analysis, Aqua-Modis Level-3 satellite data was used to observe the oceanographic variations. The data used in the analysis consisted of fishing grounds coordinate information, catches, sea surface temperature, chlorophyll-a, water depth, and salinity. The results showed that during the period 2010-2020, oceanographic dynamics did not experience significant changes or tended to be stable. Most of the research areas indicated appropriate categories for fishing activities based on the research parameters analysis. The correlation of the research parameters described a significant effect on fishing activities.

Since the fishing ground is getting farther from the coastal waters, Fish Aggregating Device is needed  as auxiliary fishing gear. Light is one of the auxiliary gear to attract fish gathering in the fishing ground. The use of underwater light has the potential to make the fish be in the target locality. Fish distribution underwater can be detected using a fish finder. Both technologies was applied to the partnership fishermen in Malalayang Satu Timur, Manado Bay, who have got impact of the coast reclamation. The technological implementation of yellow and red LED-sourced light underwater can be automatically turned on through automatically charged solar. In fishing operations, together with the partnership fishermen, the underwater light and the fish finder were put on the 3x4 m raft. Results revealed that the use of these technologies gave the economic advantage obtained that the catch has increased from the average before using the underwater light of 150 kg / trip to 400 kg / trip, after using this technologic underwater light.The average fishermen's income increased from the previous Rp 1,439,500 / trip to Rp. 4,020,000 / trip, after using of underwater light. The fish finder observation showed that the fish migration to the fishing ground was highly affected by the light color as well.Keywords: Light, fish behavior, Manado.ABSTRAKDengan semakin bergeser daerah penangkapan yang semakin jauh dari wilayah pesisir, maka diperlukan alat bantu penangkapan. Cahaya merupakan salah satu alat bantu penangkapan yang membuat ikan terpikat untuk berkumpul di suatu lokasi penangkapan. Penggunaan lampu dalam air memiliki keunggulan untuk memikat ikan karena berada langsung di lokasi ikan. Distribusi ikan yang berada di sekitar lampu dalam air dapat dideteksi dengan menggunakan fish finder. Kedua tipe teknologi ini diterapkan ke nelayan mitra di kelurahan Malalayang Satu Timur yang merupakan salah satu lokasi di Teluk Manado yang terkena dampak reklamasi di Teluk Manado. Penerapan teknologi alat bantu cahaya dua warna kuning dan merah bersumber dari lampu LED dalam air dan dapat dinyalakan secara otomatis dengan bantuan panel surya dan control charge otomatis. Dalam kegiatan penangkapan, bersama nelayan mitra, alat bantu lampu dalam air dan fish finder diletakan dirakit berukuran 3x4 m2. Keunggulan ekonomis yang diperoleh nelayan adalah jumlah hasil tangkapan mereka meningkat dari rata-rata sebelum menggunakan lampu sebanyak 150 kg/trip menjadi 400 kg/trip, setelah menggunakan lampu LED dalam air otomatis. Pendapatan nelayan rata-rata sebelum menggunakan lampu LED dalam air tenaga surya otomatis, sebesar Rp 1.439.500/trip menjadi Rp. 4.020.000/trip, setelah menggunakan lampu LED dalam air otomatis. Pengamatan dengan fish finder menunjukan bahwa migrasi ikan ke daerah penangkapan  sangat dipengaruhi oleh penggunaan warna lampu kuning dan merah.Kata kunci: Lampu, Tingkah laku ikan, Manado

Pengelolaan perikanan skala kecil di Kabupaten Bangka pada beberapa kurun waktu terakhir menunjukkan produktivitas yang semakin menurun. Hal ini disebabkan oleh pengelolaan ruang laut yang tidak hanya dimanfaatkan sebagai daerah penangkapan ikan, tetapi juga sebagai wilayah eksploitasi penambangan laut. Penelitian ini bertujuan untuk mengetahui status pemanfaatan perikanan skala kecil di perairan Kabupaten Bangka. Penelitian dilakukan dengan menggunakan data primer dan sekunder; analisis bioekonomi digunakan pada ketiga zona daerah penangkapan ikan (DPI) dengan memisahkan sumberdaya ikan pelagis dan demersal untuk melihat status pemanfaatan perikanan pada masing-masing zona. Ketiga zona daerah penangkapan ikan didasarkan pada kondisi eksisting menurut RZWP3K Provinsi Kepulauan Bangka Belitung, yaitu: Zona A (DPI dengan IUP), Zona A1 (DPI dengan IUP tanpa kegiatan), dan Zona B (DPI tanpa IUP). Hasil penelitian menunjukkan bahwa perikanan pelagis Zona A cenderung economical overfishing; sedangkan perikanan demersal sudah menunjukkan kondisi economical overfishing; Zona A1 berada pada kondisi underfishing; serta Zona B berada pada kondisi underfishing. Pemanfaatan perikanan Zona A dan A1 tidak mencapai 50% TAC; sedangkan pada Zona B hanya 15% TAC. Agar pemanfaatan perikanan baik pelagis ataupun demersal dapat berkelanjutan baik secara ekologi maupun ekonomi, pengelolaan perikanan skala kecil di perairan Kabupaten Bangka perlu dilakukan pengelolaan input pada upaya tangkap yang berbeda-beda pada tiap zona serta pengelolaan ekologi dan ekosistem.Title: Management of Small-Scale Fisheries in The Coastal Waters of Bangka Regency with Bioeconomic ApproachManagement of small-scale fisheries in Bangka Regency has recently shown decreased productivity. This is caused by the management of marine area which is not only used as a fishing ground, but also as an area of exploitation for off-shore mining. Based on these conditions, this study aims to determine the level of utilization of small-scale fisheries in the waters of Bangka Regency. This research uses primary and secondary data; bio-economic analysis was carried out in the three fishing ground zones by separating pelagic and demersal fish resources to see the utilization status of each zone. The three fishing ground zones are based on the existing fishing ground conditions according to RZWP3K Bangka Belitung Islands Province, namely: Zone A (fishing ground with IUP), Zone A1 (fishing ground with IUP without activities), and Zone B (fishing ground without IUP). The results showed that Pelagic Zone A fisheries tend to be economical, whereas demersal fisheries have shown economical overfishing; Zone A1 is under fishing; Zone B is under fishing. The utilization of fisheries in Zone A and A1 does not reach 50% TAC, while in Zone B it is only 15% TAC. For the utilization of pelagic and demersal fisheries to be sustainable both ecologically and economically, the management of small-scale fisheries in Bangka Regency waters needs to carry out input management for different fishing efforts in each zone as well as ecological and ecosystem management.
