    The use of TEDs on the “Arad” (Otter Board Boat Seine Net) has never been done by fishermen from the northern part of the Java Sea in Central Java. In order to introduce this net and also to anticipate the shrimp embargo by World Trade Organization (WTO. TEDs construction used in this study was Hooped TEDs with LxBxD dimension of 60x 40 x 60 cm; width of grids deflector of 5 cm) . This construction made an angle of 45°. Fishing operation with and without TEDs was done 9 times during the day. Shrimp, fish, others and garbage entering the net were measured in terms of body weight and fish body circle was also measured in order to compare the result of each treatment. Both nets (with and without TEDs) contained Shrimp (Metapenaeus sp), Pilot-fish (Selaroides sp), Mackerel (Rastrelliger sp), Hair-tails (Trichiurus sp, Pony-fish(Leiognathus sp), others and garbage. The average catch every hauling for the net with TEDs were : Shrimp 1.17 kg; Fish 1.66 kg; others 0.14 kg and garbage 0.1 kg; whereas the net without TEDs were : Shrimp 1.09 kg; Fish 2.33 kg, others 0.34 kg and garbage 1.31 kg. The average body circle of fish caught by net with TEDs was 4.0-7.4 cm and those caught by net without TEDs was 4.0-8.9 cm. The amount of fish and garbage caught by using each treatment differed very significantly, while the amount of shrimp caught did not

    Rawai dasar umum digunakan oleh nelayan di Perairan Pasir Kebumen. Tujuan dari penelitian ini adalah untuk menganalisis hasil tangkapan ikan kakap (Lutjanus sp) terhadap penggunaan umpan dan ukuran mata pancing yang berbeda. Penelitian ini menggunakan metode experimental fishing dengan 2 variabel yaitu jenis umpan dan ukuran mata pancing dengan 4 perlakuan yaitu (tembang,layur,nomor 6, dan nomor 9). Masing-masing dilakukan dengan 10 kali ulangan. Analisis data menggunakan uji Kenormalan data dan uji ANOVA dengan SPSS 17.0. Hasil penelitian menunjukkan bahwa umpan tembang berpengaruh terhadap hasil tangkapan dan umpan layur pada penelitian ini tidak berpengaruh terhadap jumlah hasil tangkapan Kakap (Lutjanus sp) hal ini dilihat dari hasil tangkapan umpan tembang bernomor 6 sebanyak 95 ekor, dan umpan tembang bernomor 9 sebanyak 85 ekor, serta umpan layur bernomor 6 sebanyak 57 ekor, dan umpan layur bernomor 9 sebanyak 43 ekor. Hasil uji ANOVA menunjukkan bahwa penggunaan alat tangkap pancing dengan kombinasi umpan tembang lebih baik digunakan

    Potensi sumberdaya ikan kembung yang ada di perairan Brebes perlu dilakukan upaya-upaya pemanfaatan, baik dengan cara meningkatkan USAha atau cara-cara yang sudah ada atau dengan cara mencari alternatif baru yang nantinya meningkatkan hasil tangkapan seperti yang diharapkan. Tujuan dari penelitian ini adalah mengetahui dan menganalisis pengaruh perbedaan lama perendaman pada alat tangkap jaring koncong terhadap hasil tangkapan ikan kembung, mengetahui dan menganalisis pengaruh perbedaan waktu penangkapan pada alat tangkap jaring koncong terhadap hasil tangkapan ikan kembung, dan mengetahui ada tidaknya interaksi antara perbedaan lama perendaman dengan perbedaan waktu penangkapan pada alat tangkap jaring koncong terhadap hasil tangkapan ikan kembung. Metode penelitian yang digunakan adalah metode experimental fishing dengan 2 variabel yaitu lama perendaman dan waktu penangkapan dengan 6 perlakuan. Analisis data menggunakan uji normalitas One-Sample Kolmogorov Smirnov, uji ANOVA RAL faktorial, dan uji Duncan. Hasil penelitian menunjukkan bahwa perbedaan lama perendaman ada pengaruh terhadap jumlah tangkapan dan berat tangkapan ikan kembung yaitu yang terbaik adalah lama perendaman 3 jam; perbedaan waktu penangkapan ada pengaruh terhadap jumlah tangkapan dan berat tangkapan ikan kembung yaitu yang terbaik adalah waktu penangkapan pagi; dan tidak ada pengaruh interaksi antara perbedaan lama perendaman waktu penangkapan terhadap jumlah dan berat tangkapan ikan kembung. Mackerel resource potential in Brebes waters efforts need some efforts to use it, either by increasing the effort or means of an existing a new way of alternatives that will improve the catch as expected. The purpose of this study was to determine and analyze the effect of different soaking time on fishing gear for koncong net to catch mackerel, knowing and analyze the effect of different fishing time on fishing gear for jaring koncong to catch mackerel, and determine whether an interaction between difference soaking time and fishing time on koncong net to catch mackerel. The research method was the experimental fishing with 2 variables which are the type of soaking time and fishing time with 6 treatments. The data analysis used were the normality test One-Sample Kolmogorov Smirnov, RAL factorial ANOVA test and Duncan test. The results showed that the differences soaking time has an effect on the total catch and catch weight of mackerel, and the best is 3 hours soaking time; differences fishing time has an effect on the total catch and catch weight of mackerel, and the best is morning fishing time; and there was no interaction effect between difference soaking time and fishing time for the number and the weight of mackerel catch

    Anco is a very simple lift net, generally used only by small fishermans. The shape of the tool is rectangular. The shape is used because after setting and hanging, the other side of the net look like a cup. Anco is used on the edge of the river and the swamp, especially in the estuarine water stream. On that section, there are many small fish schooling because the fish like to swim on the opposing direction of the water stream. Bait is used as stimulant for the fish, so that the fish schools around the anco net. The purpose of this reseatch is to analyze the use of shrimp's natural bait, worm and cassava against the anco net catch result and to know what bait that has the biggest influence against the anco net catch result. The research method used is descriptive, this research is an experimental research to test modified bait from many kinds of bait (mashed worms, mashed shrimp, mashed cassava) against the catching result in the use of anco net to catch fish. Direct observation method, interview, documentation, and literature is used to collect data. Data is then analyzed using statistic test including testing the normality, testing the homogenity, and one way Anova testing. The results of three treatmens used in the research are shrimp bait, worm, and cassava. The bait which has the most catching result in terms of result, 928 fishes and weighing 3,193 kg, but, the most catching result in the terms of weight is the shrimp bait, weighing 6,466 kg, 840 fishes. The worm bait resulting in 758 fishes, weighing 5,285 kg
