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. Permasalahan yang sering menghambat perkembangan pulau-pulau terluar seperti Pulau Marore adalah masih rendahnya kemampuan masyarakat untuk mengelola potensi sumberdaya laut dan minimnya sarana dan prasarana produksi. Ciri khas suatu wilayah kepulauan adalah memiliki sumberdaya perikanan yang relative tinggi, tetapi sangat rentan terhadap degradasi lingkungan dengan kondisi meteorologis yang sangat dinamis dan sulit diprediksi. Pancing dasar merupakan salah satu alat tangkap yang banyak di gunakan oleh nelayan di PulauMarore untuk menangkap ikan-ikan dasar; tetapi belum diketahui umpan mana yang paling efektif untuk menangkap ikan-ikan tersebut. Oleh karena itu penelitian ini bertujuan untuk mempelajari pengaruh jenis umpan terhadap hasil tangkapan pancing dasar; dan mengidentifikasi jenis-jenis ikan yang tertangkap.  Penelitian ini dilakukan pada bulan November-Desember 2016 dengan metode eksperimental. Umpan yang digunakan terdiri dari ikan layang (Decapterusmacarellus), selar (Selaroides sp.), tongkol (Auxix rochei.) dan cumi-cumi (Loligo sp.).dan data dianalisis menggunakan rancangan acak kelompok.  Hasil tangkapan total sebanyak 136 ekor; yang terdiri dari 6 famili, 14 genus dan 24 spesiesikan. Analisis sidik ragam menunjukkan bahwa perbedaan jenis umpan pada pancing dasar memberikan pengaruh yang sangat nyata terhadap hasil tangkapan. Hasil uji BNT untuk perlakuan menunjukkan bahwa penggunaan umpan cumi berbeda sangat nyata dengan ketiga umpan lainnya. Penggunaan umpan laying tidak berbeda dengan umpan tongkol tetapi berbeda sangat nyata dengan umpan selar. Penggunaan umpan tongkol tidak berbeda nyata dengan umpan selar.Kata-kata kunci: PulauTerluar, PulauMarore, ikan-ikankarang, pancing dasar

ABSTRACT Tuna, a dominant commodity in national capture fisheries sector, has significantly contributed to the development of the nation as a source of fishermen livelihoods and food for people. One alternative fishing gear to catch tuna is hand lines using artificial bait made of waste plastic packaging. The use of such artificial bait catches sufficient number of fish but the size of the artificial bait used cannot be determined with certainty. This study established the size of artificial bait which gives the best catches based on operating time by using Randomized Block Design and Least Significant Difference test. The analysis showed that the bait size of 7.0´0.6 cm had the most catch of Thunnus albacores and Katsuwonus pelamis. Total catch was 227 fish, total length 20 – 30 cm and width of the body 9.5 – 21.5 cm. Keywords: resource, artificial bait, tuna hand line, tuna albacore   ABSTRAK Tuna, komoditas unggulan sektor perikanan tangkap nasional, telah memberikan kontribusi yang relatif lebih besar kepada pembangunan bangsa, antara lain sebagai sumber mata pencaharian nelayan serta penyedia kebutuhan konsumsi masyarakat. Salah satu alternatif alat tangkap untuk menangkap jenis tuna adalah pancing ulur menggunakan umpan buatan dari bahan limbah plastik kemasan. Penggunaan umpan buatan ini memberikan hasil tangkapan yang cukup tetapi ukuran umpan buatan yang digunakan tidak dapat ditentukan dengan pasti.        Penelitian ini menetapkan ukuran umpan buatan mana yang memberikan hasil tangkapan terbaik berdasarkan waktu pengoperasian dengan menggunakan Rancangan Acak Kelompok (RAK) dan untuk mengetahui umpan buatan yang paling baik diantara umpan buatan yang digunakan dianalisa dengan Uji Beda Nyata Terkecil (BNT).

Effect Of Light

Using blinking Light Emiting Diode (LED) could increase the fishing power of bottom traps. The objective of this research was to study the effect of light intensity of LED (blinking lamp) inside the trap and moon phase toward the capture of coral fishes. Three light intensities of LED were used: 35 lux (2 LED), 70 lux (4 LED), 105 lux (6 LED) and one without blinking lamp as a control. Catch data were collected using 12 units of bottom traps operating in coral waters of Ternate Island at depths around 5 to 7 m.Data analysis wasdone based on randomized block design. The catch was 181 fish in total comprising 12 families, 17 genera and 28 species. Analysis of variance showed that using different light intensity of LED on bottom traps and different moon phase caused highly significant effect in catch. Least significant differences test showed that using light intensity 105 lux (6 LED) inside the trap is not significant in catch to 70 lux (4 LED), but highly significant to 35 lux (2 LED) and control. Light intensity 70 lux (4 LED) is not significant in catch to 35 lux (2 LED), but highly significant to control. There was no significant difference between light intensity 70 lux (4 LED) and control. Catch of trap could increase when using higher light intensity of blinking lamp (LED) and the catch of trap also increase when operated around dark moon. It is better to use high light intensity of blinking lamp (105 lux) inside the trap, and operated in dark moon to catch coral fishes© Penggunaan lampu LED (Ligh Emiting Diode) berkedip didalam bubu diduga dapat meningkatkan kemampuan tangkap. Penelitian ini bertujuan untuk mempelajari pengaruh intensitas cahaya lampu LED berkedip di dalam bubu dan fase umur bulan terhadap hasil tangkapan ikan-ikan karang. Tiga jenis intensitas cahaya lampu yang digunakan, yaitu 35 lux (2 LED), 70 lux (4 LED), 105 lux (6 LED), dan lampu LED tanpa berkedip sebagai kontrol. Data dikumpulkan dengan mengoperasikan 12 unit bubu di perairan karang Pulau Ternate pada kedalaman sekitar 5–7 m; dan dianalisis berdasarkan Rancangan Acak Kelompok. Hasil tangkapan total sebanyak 181 ekor; terdiri dari 15 famili, 25 genus, dan 35 jenis. Analisis sidik ragam menunjukkan bahwa perbedaan intensitas cahaya lampu LED dalam bubu dan perbedaan fase umur bulan berpengaruh sangat nyata terhadap hasil tangkapan. Hasil uji BNT untuk perlakuan menunjukkan bahwa penggunaan lampu 6 LED (105 lux) pada bubu tidak berbeda nyata dengan penggunaan lampu 4 LED (70 lux) tetapi berbeda sangat nyata dengan penggunaan lampu 2 LED (35 lux) dan Kontrol. Demikian juga lampu 4 LED tidak berbeda nyata dengan lampu 2 LED tetapi berbeda sangat nyata dengan Kontrol; sedangkan antara lampu 2 LED dan Kontrol tidak ada perbedaan yang nyata. Hasil tangkapan bubu meningkat ketika menggunakan lampu kedip dengan intensitas yang lebih tinggi; dan dioperasikan pada saat bulan gelap. Sebaiknya menggunakan lampu LED berkedip 105 lux dan dioperasikan saat bulan gelap untuk menangkap ikan-ikan karang dengan bubu©

Fish Catch

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.

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.

Combining ability and heterosis were calculated for fourteen lines of linseed in a line × tester mating design using twelve lines and two diverse testers in two different environments. The hybrids and parental lines were raised in a completely randomized block design with three replications to investigate seed and fibre yield and their component traits. Genetic variation was significant for most of the traits over environments. Combining ability studies revealed that the lines KL-221 and LCK-9826 were good general combiners for seed yield and most of its components, whereas LMH-62 and LC-2323 were good general combiners for yield components only. Moreover, KL-221 was also a good general combiner for fibre yield. Similarly, B-509 and Ariane were good general combiners for fibre yield and most of its components. Among the specific cross combinations, B-509 × Flak-1 was outstanding for seed yield per plant and B-509 × KL-187 and LC-2323 × LCK-9826 for fibre yield per plant, with high SCA effects. In general, the hybrids excelled their respective parents and the standard checks for most of the characters studied. Based on the comparison of mean performance, SCA effects and the extent of heterosis, the hybrids LC-2323 × LCK-9826 and B-509 × KL-221 appeared to be the most promising for both seed and fibre yield. Other promising combinations were LC-2323 × KL-210 and B-509 × Ariane for seed and fibre yield, respectively. The superiority of LC-2323, LCK-9826, KL-221, B-509 and Ariane as good general combiners was further confirmed by the involvement of these parents in the desirable cross combinations.

Penelitian ini dilakukan untuk mendapatkan informasi tentang kebutuhan optimum kadar protein dan lemak pakan terhadap pertumbuhan dan komposisi badan ikan kerapu macan ukuran konsumsi. Sembilan pakan uji dibuat dalam bentuk moist pelet dengan tiga dosis protein (46%, 49%, dan 52%) dan tiga dosis lemak (9%, 11%, dan 13%). Ikan uji dipelihara dalam 27 keramba jaring apung ukuran 1 m x 1 m x 2 m selama 140 hari, diberi pakan uji secara satiasi dua kali sehari dan diset dalam rancangan acak kelompok pola faktorial berdasarkan kelompok ukuran bobot awal ikan yaitu (i) 122,0±4,2 g; (ii) 144,0±7,1 g; dan (iii) 172,9±10,5 g. Hasil penelitian menunjukkan bahwa laju pertumbuhan spesifik dan sintasan ikan relatif sama (>0,05) di antara perlakuan. Efisiensi pakan cenderung meningkat dengan meningkatnya kadar protein dan lemak pakan. Tingkat efisiensi pemanfaatan protein cenderung menurun dengan meningkatnya kadar protein pakan, tetapi meningkat dengan meningkatnya kadar lemak pakan. Hasil analisis proksimat badan ikan menunjukkan bahwa kadar bahan kering dan lemak ikan relatif tidak dipengaruhi (P>0,05) oleh peningkatan kadar protein pakan, namun kadar bahan kering dan lemak ikan tersebut sedikit naik dengan meningkatnya kadar lemak pakan. Kadar protein dan abu ikan relatif tidak dipengaruhi oleh perubahan kadar protein dan lemak pakan. Berdasarkan hasil penelitian ini tampak bahwa pakan dengan kadar protein 49% dan lemak sekitar 11% mampu memberikan pertumbuhan dan komposisi badan ikan kerapu macan yang baik.This experiment was conducted to investigate the optimum dietary protein and lipid level for growth and body composition of tiger grouper. Nine dietary experiments were formulated to moist pellet contain three levels of protein (46%, 49%, and 52%) and three levels of lipid (9%, 11%, and 13%). The fish were fed twice daily to satiation for 140 days in twenty seven net cages of 1 m x 1 m x 2 m, were set up factorial randomized block design based on fish size group i.e. (i) 122.0±4.2 g, (ii) 144.0±7.1 g, and (iii) 172.9±10.5 g. The results shown that specific growth rate and survival rate were not significant different (P>0.05) for all treatments. Feed efficiency increased when protein and lipid content increased. Protein efficiency decreased when protein diets increased and increased when lipid diets increased. No interaction occurred between protein and lipid content to all observable biological variables. Dry matter and lipid content of test fish were not affected by protein diets increase but by lipid diet content. Protein and ash of test fish were not affected by either protein or lipid contained in diet. To assure high growth rates and high quality of fish product, it is suggested to feed tiger grouper with diet containing 49% protein and 11% lipid.
