This descriptive study using literature and field research is to determine the contribution of purseseine fishery to the gross regional domestic product (GRDP) of Manado. The results showed that the sub-sector of fishery has a LQ (location quotient) < 1 (average 0.30). It means, the sub-sector of fishery in Manado is not an important sector in Manado. To fulfill the Manadonian needs, import of fish is expected to be necessary. The purseseine fishery has a high contribution to the GRDP of Manado, from 1.58% in 2003 to 82.5% in 2012 (annual average of 30.5%) with average growth of 71.5% per year, based on market price. The revenue of ship's crews depends on each person's responsibility on the ship. Financial analysis concluded that purseseine fishery is economically feasible with R/C ratio varying from 1.09 to 1.22 (average 1.16). The operational...

Using several kinds of bait could increase the fishing power of the traps. The objective of this research was to study experimentally the effect of several kinds of trap baits and moon phases toward the capture of mangrove crab. Catch data were collected using 12 units of traps,which operated in the estuary waters of Kalurae Village, Regency of Sangihe Islands. Four kinds of bait were used to trap: scads mackerel (Decapterus macarellus), little tuna (Euthynnus sp.), trevally(Caranx sp.) and chicken innards. Data were analyzed by randomized block design. Analysis of variance showed that different types of bait on the trap and moon phase caused highly significant effect on catch. Least significant differences test showed that using scads mackerel bait on the trap was not significantly different from little tuna bait, but differed significantly from trevally and chicken innards baits.

These fish live around the bottom with complex topography, so that not all fishing gears can be operated in that area, except bottom hand line. This fishing gear has been widely used by coastal communities in North Sulawesi to catch demersal fishes, since it is simple, cheap, and easy to manage with a small boat. Although the gear’s design has evolved over centuries, there is still potential to develop for environmental safety and sustainability. The objective of this research was to study the effect of different baits and operation times on the fish catch and identify the fish species. This research was done in Manado Bay waters, North Sulawesi, on July to October 2018, using an experimental method.

This study attempted to evaluate the impact of different fishing gears utilized by traditional fishermen on the fish resources and their habitats and formulate an environmenttal friendly fishing fisheries concept. Data collection used two approaches, through a long-term catch analysis and a direct field observation on the fishing process. Results found that several fishing gears used were potential to cause damages on bottom habitats due to the operational technique and the treatment to the gear itself. Beside that, some gears were also potential to unbalance the stability and the the sustainability of the fish resources due to the utilization of excessively small-sized mesh. Based on the internal factor analysis strategy (IFAS) and the external factor analysis strategy (EFAS), the use of fish traps, circling gill nets, ...

This swimming crab in coastal waters of North Sulawesi usually caught accidentally (by catch) with bottom gillnets. There has been a special fishing gear for crab traps, but not known by local fishermen. The differences of trap shape could increase the fishing power of swimming crab traps; but such scientific information is not widely available yet. Therefore, this research aimed to study the effect of pots shape to catch swimming crab; and identifies the types of biota captured. This research was conducted in the coastal waters of Kema Tiga village, North Minahasa Regency; from September to December 2014; which is based on the experimental method. Bubu six units of traps (three units conical shape, and three other rectangular shape), operated for eight nights to collect data; used scad mackerel bait; and the capture data were analyzed...

Degradation of coral reefs in the waters of Pulau Lembeh, Bitung caused by fishing activities were not responsible. However, there have been attempts to build artifial reefs since 2014 to protect natural coral reefs as well as repairing the damaged coral reefs. It is necessary to hold monitoring association of fish species target on artificial reef has been built with Acropora sp. trasnplantated. This research was conducted in Mawali Village, Lembeh Strait, on August - December 2016; done with descriptive method; and the data were analyzed through the diversity and richness index. Results of the analysis showed that the diversity of species classified as moderate with a value of 2.85; and species richness is high with a value of 6.09. This figure reflects the dominance of Cheilodipterus isostigmus species to other species in terms of number. Oceanography parameters such as temperature (...

The operation, however, sometimes is done in damaging ways to fish resources and the environment. Therefore, this research aims to study the species and composition of catches of soma darape, as well as assessing the legal size of catches. This research was done in coastal waters near mangrove of Bajo Village, Tatapaan District, South Minahasa Regency in June 2015; based on descriptive method. The catch consisted of 19 species, and the predominant species (≥ 20) were Scatophagus argus (42), Tylosurus crocodiles (33), Carangoides ferdau (27), Scylla serrata (26), Leiognathus smithursti (21) and Terapon jarbua (20). There were 6 species that have a legal size, namely Terapon jarbua (1), Scatophagus argus (18), Siganus canaliculatus (3), Lutjanus fulvus (5), Sillago analysts (16) and Scylla serrata (1). Of th...

Sumberdaya tersebut tersebar pada delapan daerah penangkapan, yaitu Selat Malaka , Laut Jawa dan Selat Sunda, Samudera Hindia, Selat Makasar , Laut Pasifik, Teluk Tomini, Laut Banda , dan Laut Arafura (Komisi Nasional Pengkajian Stok Sumberdaya Ikan Laut ,1998). Ikan selar/ikan malalugis putih adalah komoditi ekspor yang penting sejak tahun 1993. Salah satu tingkah laku ikan yang bermanfaat dalam pengembangan dan perbaikan metode penangkapan dengan jaring insang ”soma darape” adalah tingkat distribusi tertangkapnya ikan pada alat tangkap soma darape di rumpon. Dengan pengetahuan ini, setidaknya berbagai kendala dalam penentuan desain dan teknis operasi alat tangkap dapat diatasi. Soma darape atau jaring insang permukaan yang ada di Kelurahan Malalayang Satu Timur kecamatan Malalayang Kota Manado dioperasikan di sekitar rumpon dengan cara menghadang ikan...

It has also established requirements for marine fisheries products (fresh or processed products) exported directly or indirectly to European Union must be free of IUU Fshing. The fish catch certification follows the legal aspects and national reguaations in line with international regulations. Fish catch certification consists of Initial Sheet, Derivative Sheet, and Simplified Derivative Sheet. The objectives of the study are to know the issuance procedure of fish catch certificate in the form of preliminary document, the issuance procedure of fich catch certificate iin the form of derivative document as export supporting document, and the issuance procedure of fish catch certificate in simple form of derivative document. This study was carried out in September - November 2016 in Samudera Bitung Fisheries Port. The initial sheet is use...

Produk domestik regional bruto (PDRB) adalah salah satu indikator untuk menelaah struktur perekonomian suatu daerah. Dengan menggunakan metode survey, penelitian ini bertujuan untuk mengetahui seberapa besar kontribusi: (1) PDRB Raja Ampat terhadap PDRB Papua Barat, (2) PDRB Raja Ampat dari subsektor perikanan terhadap PDRB Papua Barat dari subsektor tersebut, dan (3) kontribusi perikanan laut terhadap PDRB Kabupaten Raja Ampat. Hasil penelitian menunjukkan bahwa: (1) Dengan PDRB Migas, PDRB Raja Ampat berkontribusi 3,73% per tahun (ADHB) dan 4,99% per tahun (ADHK) terhadap PDRB Papua Barat selama periode 2009 - 2013; sedangkan tanpa PDRB Migas, PDRB Raja Ampat berkontribusi 3,87% per tahun (ADHB) dan 4,4...
