Abstract

Moonfish (Mene maculata) known locally as bete tamako or peda cina, is one of the  economically important fish resources resulting from Buyat Bay. Although it has relatively small size (estimated length 25-30 cm), but the fish has a good taste. The presence of moonfish is usually a sign of sailfish fishing season in the Buyat Bay. Common fishing gear used to catch moonfish is hand line , noru.  However, scientific information about the status of moonfish fishery was not yet understood. Therefore, this study aims to determine the status of moonfish fishery and map out the fishing location.  This research was conducted in the Buyat Bay, Ratatotok District, Southeast Minahasa Regency (March-September 2013); using a survey method with a descriptive approach. Catch data were analyzed by a surplus production model.  These results informed that the maximum sustainable yields (MSYs)  was 1707 fish/trip/year where the number of  the suitable fishing trips was 470 trips.

Abstract

Title (Bahasa Indonesia): Pengaruh jenis umpan terhadap hasil tangkapan ikan cendro [Tylosurus sp.] dengan pancing layang-layang. Needlefish is one of the economically important fish resources from Bangka Strait North Minahasa regency. Common fishing gear used by fishermen is kite fishing. Although this gear is very simple and traditional, but its efficiency and selectivity of fishing have potential to meet the development of environmentally friendly and sustainable criteria. The success of kite fishing, relies on the availability of fish bait; therefore, the purpose of this research was to study the effect of kite fishing baits onneedlefish catch; and identify the types of fish caught. This research was done in Bangka Strait North of Minahasa, based on experimental method. Four kinds of bait were used as treatment, scad (Decapterus macarellus), sardine (Sardinella gibosa), anchovy (Stolephorus indicus) and artificial bait of plastic hose. Catch data were collected using 8 units of  kite fishing; and data analysis was done based on randomized block design. The catch was 61 fish in total consisting of Tylosurus crocodiles (57 fish) andTylosurus acus melanotus (4 fish). ANOVA showed that the difference of kite fishing baits caused high significant effect in catch of needlefish. The LSD for the treatment declared that the use of sardine bait wassignificantly different from anchovy, scad  and  artificial baits. The use of anchovy baits was also significantly different from scad and artificial baits,but there was no significant difference between scad baits and artificial baits. Ikan cendro merupakan salah satu sumberdaya ekonomis penting dari perairan Selat Bangka Kabupaten Minahasa Utara. Alat tangkap yang umum digunakan oleh nelayan adalah pancing layang-layang. Walapun alat ini sangat sederhana dan tradisional, tetapi masih memiliki potensi untuk meningkatkan efesiensi penangkapan dan selektivitas dalam memenuhi pengembangan kriteria ramah lingkungan dan berkelanjutan. Keberhasilan pancing layang-layang sangat bergantung pada ketersedian ikan umpan, oleh karena itu tujuan penelitian ini adalah mengetahui pengaruh jenis umpan pada pancing layang-layang terhadap tangkapan ikan cendro dan mengidentifikasi jenis-jenis ikan yang  tertangkap. Penelitian ini dilakukan di perairan Selat Bangka Minahasa Utara, didasarkan pada metoda eksperimental. Empat jenis umpan yang digunakan sebagai perlakuan, yaituikan layang(Decapterus macarellus), ikan sardin (Sardinella gibosa), ikan teri(Stolephorus indicus) dan umpan buatan selang plastik. Data tangkapan dikumpulkan mengunakan 8 (delapan) unit pancing layang-layang dan analisis data didasarkan pada rancangan acak kelompok. Tangkapan total sebanyak 61 ekor yang terdiri dari Tylosurus crocodiles (57 ekor)danTylosurus acus melanotus (4 ekor). Analisis sidik ragam menunjukkan bahwa perbedaan umpan pada pancing layang-layang memberikan pengaruh yang sangat nyata terhadap hasil tangkapan ikan cendro. Uji BNT untuk perlakuan menyatakan bahwa penggunaan umpan sardin berbeda sangat nyata dengan umpan teri, umpan layang dan umpan buatan. Penggunaan umpan teri juga berbeda dengan umpan layang dan umpan buatan tetapi tidak ada perbedaan antara umpan layang dan umpan buatan.

Abstract

Trap is one of the common fishing gears used by the fishermen to catch mangrove crabs. 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. Similarly, using little tuna bait was not significantly different from trevally bait, but differed significantly from chicken innards bait; and trevally bait was not different from chicken innards bait. Catching mangrove crabs with traps should use scads mackerel and little tuna baits, and be operated around the new moon phase© Bubu merupakan alat tangkap yang umum digunakan nelayan untuk menangkap kepiting bakau. Penggunaan beberapa jenis umpan, diduga dapat meningkatkan fishing power dari alat tangkap bubu. Penelitian ini bertujuan mempelajari pengaruh jenis umpan bubu dan fase umur bulan di langit terhadap hasil tangkapan kepiting bakau; dikerjakan dengan metode eksperimental. Data tangkapan dikumpulkan dengan mengoperasikan 12 unit bubu, di perairan estuari Kampung Kalurae, Kabupaten Kepulauan Sangihe. Empat jenis umpan yang diperlakukan, yaitu ikan layang (Decapterus macarellus), tongkol (Euthynnus sp.), selar (Caranx sp.) dan jeroan ayam. Data dianalisis berdasarkan Rancangan Acak Kelompok. Analisis Sidik Ragam menunjukkan bahwa perbedaan jenis umpan pada bubu dan fase umur bulan berpengaruh sangat nyata terhadap hasil tangkapan. Uji Beda Nyata Terkecil menyatakan bahwa penggunaan jenis umpan layang pada bubu tidak berbeda nyata dengan umpan tongkol, tetapi berbeda sangat nyata dengan penggunaan umpan selar dan umpan jeroan. Demikian juga penggunaan umpan tongkol tidak berbeda nyata dengan umpan selar, tetapi berbeda sangat nyata dengan umpan jeroan; sedangkan penggunaan antara umpan selar dan jeroan tidak ada perbedaan yang nyata. Umpan ikan layang dan ikan tongkol serta fase umur bulan I dan fase IV memberikan hasil tangkapan kepiting bakau yang lebih baik©

Abstract

Mangrove gives major contributions to fishery production; however, due to an increasing demand of space for human activities, mangrove area is changed to many forms, such as settlement, industry, and recreation; beside lack of data and information available (biophysics, socio-economic, and culture). These may cause economical and ecological conflicts. This condition is currently happened in Marine Tourism Park of Kupang Bay (MTPKB). Accordingly, this study aims to analyze community structure of mangrove at MTPKB using survey method to observe mangrove vegetation and exploitation impact by community. In this study, 16 species of 9 families were found with categorized density from “rare” (20 individual/hectare) to “dense” (5.450 individual/hectare). The ecosystem was found has low diversity; it was due to high dominant index. Rhyzophora apiculata and Sonneratia alba were found two species which have big role in the marine park© Mangrove memberikan kontribusi yang besar terhadap produksi perikanan; namun, oleh karena kebutuhan manusia yang semakin meningkat, daerah mangrove dirubah menjadi daerah pemukiman, industri, dan rekreasi; di samping kurangnya data dan informasi yang tersedia. Hal ini dapat menimbulkan konflik secara ekonomi dan ekologi. Kondisi ini sedang terjadi di Taman Wisata Alam Laut Teluk Kupang (TWALTK). Oleh karena itu, penelitian ini dilakukan di mana bertujuan menganalisis struktur komunitas mangrove di TWALTK dengan menggunakan metode survei untuk melakukan pengamatan terhadap vegetasi mangrove dan aktifitas masyarakat dalam memanfaatkannya. Dalam penelitian ini ditemukan 16 jenis mangrove dari 9 famili dengan kerapatan terkategori dari ‘jarang’ (20 pohon/hektar) hingga ‘padat’ (5.450 pohon/hektar). Keanekaragaman ekosistem tersebut rendah karena tingginya nilai dominasi. Jenis Rhyzophora apiculata dan Sonneratia alba merupakan jenis yang memberikan pengaruh besar terhadap komunitas mangrove di taman wisata alam laut tersebut©

Abstract

Trolling board is an important troll line accessory which can produce swinging and diving movements of the lure. A laboratory study on the effect of trolling board main line position and current speed on swinging and diving movements was done in a water circulating tank at the Faculty of Fisheries and Marine Science, Sam Ratulangi University. At low speed, the widest swing reached at main line position near the center of trolling board, but at high speed, it reached main line position near the fore tip. Swinging frequency decreased with the current speed. The depth of diving increased as the main line position got closer to the tip and increased with current speed.

Abstract

Bottom trap have been used widely by coastal communities in North Sulawesi to catch coral fishes, since it simple in design, cheaper and easy to manage with a small boat. Unfortunately, the fishing practice of the traditional trap is usually conducted in destructive way, where fishermen cover the gear with live coral to attract fishing target.  Although the gear’s design has evolved over centuries, there is still potential for improving its catching efficiency and selectivity. An attempt to understand the fishing process of bottom trap should therefore be focused on bait and how its chemical composition, visual and physical properties may stimulate target species to attack the bait and captured. Addition of squid liver oil to the bait could increase the fishing power of bottom trap gear. But scientific information’s about its applications are not available yet. Therefore, the objective of this research was to study the effect of squid liver oil on bait of bottom trap toward the capture of coral fishes. This research was done in Bangka Strait North of Minahasa, based on experimental method. Six units of bottom trap (bamboo) were operated ten nights in collecting data; where tree units of them used scad mackerel bait that injected by squid liver oil, and tree other units just used scad mackerel bait without squid liver oil; and the capture data were analyzed by ttest. The catch was 117 fish in total consist of 2 genera; 74 fish was caught by scad mackerel bait with squid liver oil, and 43 fish was caught by bait without squid liver oil. Analysis of ttest show that t0= 8.908>t0.05; 5= 3.250; which means that the addition of squid liver oil on bait could increase the catch of bottom trap.
