Perbedaan umpan dan waktu pengoperasian pancing dasar terhadap hasil tangkapan di Teluk Manado

One of the important economic resources of North Sulawesi waters is demersal fish, such as deep sea red snapper. 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. The baits were mackerel fish (Decapterus sp), frigate tuna (Auxis rochii), squid (Loligo sp), and anchovies (Stolephorus sp). This fishing gear was operated in the morning and afternoon. The study applied randomized block design. Results found 67 fish consisting of 5 species. ANOVA showed that bait types gave significant effect on the fish catch, but operation time did not significantly affect the catch. BNT test revealed that the use of mackerel bait did not give significantly different effect on fish catch from that of squid bait, but very significantly different effect on the fish catch from that of frigate tuna bait and anchovy bait.ABSTRAKSalah satu sumberdaya ekonomis penting perairan Sulawesi Utara adalah ikan demersal seperti kakap merah laut dalam. Jenis-jenis ikan ini hidup di dasar perairan dengan topografi yang kompleks, sehingga tidak semua alat tangkap dapat dioperasikan di daerah tersebut, kecuali alat tangkap pancing dasar. Pancing dasar merupakan salah satu alat tangkap yang umum digunakan oleh masyarakat nelayan untuk menangkap ikan demersal, karena konstruksinya sederhana, relatif murah dan mudah dioperasikan dengan kapal ukuran kecil. Walaupun alat tangkap ini telah berkembang sejak lama, tetapi efisiensi penangkapan ikan dan selektivitasnya masih memiliki potensi pengembangan untuk memenuhi kriteria ramah lingkungan dan berkelanjutan. Penelitian ini bertujuan untuk mempelajari pengharuh jenis umpan dan waktu operasi terhadap hasil tangkapan pancing dasar, dan mengidentifikasi jenis-jenis ikan yang tertangkap. Penelitian ini dikerjakan di perairan Teluk Manado pada bulan Juli – Oktober 2018, yang didasarkan pada metode eksperimental fishing. Umpan yang digunakan terdiri dari ikan layang (Decapterus sp), tongkol (Auxis rochii), cumi-cumi (Loligo sp), teri (Stolephorus sp) yang tersedia selama penelitian. Alat tangkap ini dioperasikan pada pagi hari dan sore hari. Penelitian ini menggunakan rancangan acak kelompok. Hasil tangkapan total sebanyak 67 ekor, yang terdiri dari 5 spesies ikan. Analisis sidik ragam menunjukan bahwa perbedaan jenis umpan pada pancing dasar memberikan pengaruh yang nyata terhadap hasil tangkapan. Tetapi perbedaan jam operasi tidak berpengaruh nyata terhadap hasil tangkapan. Hasil uji BNT untuk perlakuan menunjukkan bahwa penggunaan umpan layang tidak berbeda nyata dengan umpan cumi, tetapi berbeda sangat nyata dengan umpan tongkol dan umpan teri.

An experiment was conducted during pre-kharif season of 2016 and 2017 to determine the efficacy of relatively cheaper, safer horticultural mineral oil on yellow mite (Polyphagotarsonemus latus). The experiment was laid out in randomized block design with seven treatments [T1- mineral oil @ 3 ml/litre at 35 and 50 days after sowing, T2- mineral oil @ 6 ml/litre at 35 and 50 DAS, T3- mineral oil @ 9 ml/litre at 35 and 50 DAS, T4-Neem oil @ 3 ml/litre at 35 and 50 DAS, T5- mineral oil @ 3 ml/litre + neem oil @ 3 ml/litre at 35 and 50 DAS and T6- Control] replicated four times. Two scheduled spraying of each treatment was done on standing jute crop at 15 days interval. The effect of treatments was significant on post treatment mite population recorded after spray for both the cropping season. Among the treatments, T5 was found to be the most effective combination. The post treatment observation during 2016 and 2017 at 7 days after treatment indicated significantly less number of mites i.e. (1.08 and 0.84 mites cm-2) and (0.83 and 0.41 mites cm-2) respectively in the treatment T5. Within the treatments, maximum plant height (216.92 and 206.64 cm) and yield (34.68 and 28.28 q ha-1) were also observed in treatment T5. Considering the effectiveness against mite on jute as well as the environmental safety, mineral oil might be suggested as biorational component of IPM for effective management of yellow mite.

Marore Island is one of the northernmost outermost islands in the territorial waters of Indonesia. The problems that often hamper the development of outer islands are the low ability of the community to manage the potential of marine resources and the lack of production facilities and infrastructure. Characteristic of an archipelagic region is to have relatively high fishery resources, but very susceptible to environmental degradation with very dynamic and unpredictable meteorological conditions. Bottom hand line is one of the many fishing gear used by fishermen in Marore Island to catch bottom fish; but it is not yet known which bait is most effective for catching the fish. Therefore this study aims to study the effect of different kind of bait on the catch of bottom hand line, and to identify the catch. This research was conducted in November until December 2016 with experimental method. The baits used consist of mackerel fish (Decapterus macarellus), selar (Selaroides sp.), frigate tuna (Auxixrochei.) and squid (Loligo sp.); the data were analyzed using randomized block design. Total catch of 136 fish; which consists of 6 families, 14 genera and 24 species. Analysis of variance show that the use of mackerel bait is no different from frigate tuna, but significantly different from selar; the use of frigate tuna bait is not significantly different from selar.Keywords: Outer Island, Marore Island, coral fishes, bottom hand lineABSTRAKPulau Marore adalah salah satu pulau terluar paling utara di wilayah perairan Indonesia.

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.
