Abstract

Perairan Karang Jeruk merupakan kawasan konservasi ekosistem terumbu karang yang terletak di Dukuh Larangan (Desa Munjungagung, Kabupaten Tegal, di Provinsi Jawa Tengah) yang memiliki kekayaan sumber daya perikanan yang baik. Alat tangkap yang banyak terdapat di perairan Karang Jeruk adalah payang gemplo dan mini purse seine. Penggunaan teknologi rumpon portable diharapkan dapat menciptakan daerah penangkapan ikan dan mengantisipasi timbulnya degradasi daerah penangkapan ikan. Tujuan dari kegiatan ini adalah menganalisis persepsi nelayan terhadap penggunaan inovasi rumpon portable di perairan Karang Jeruk, Kabupaten Tegal. Penelitian ini menggunakan metode wawancara dan experimental fishing. Data persepsi nelayan dilakukan dengan cara wawancara menggunakan kuesioner kepada 50 nelayan payang gemplo dan mini purse seine, dengan penentuan responden secara accidental sampling. Seluruh nilai persepsi nelayan terhadap rumpon portable dikelompokkan menjadi 3 kategori, sebagian besar nelayan memiliki persepsi pada tingkat tinggi sebanyak 38 orang (76%), tingkat sedang sebanyak 11 orang (22%), dan tingkat rendah hanya 1 orang (2%). Penggunaan rumpon portable memiliki keunggulan diantaranya: produktivitas tangkapan yang banyak, jenis tangkapan beragam, dan komposisi ikan kategori layak tangkap yang banyak.

Abstract

Mukomuko Regency is one of Bengkulu Province's regencies with abundant marine resources. It has a fishing port, one of which is the Ipuh sub-district fishing port and the Teramangjaya sub-district fishing port. This study aimed to determine the size, length, weight, and composition of shark species landed at the Mukomuko Regency fishing port to identify the types of sharks that are protected based on the IUCN conservation status and the suitability of shark catches. The survey method was used to visit the research location at the ship's landing port, measure the length and weight of the sharks, and take pictures of them. The results of the sharks obtained were two species of sharks, namely the kejen shark (Loxodon Macrorhinus) with a status of almost threatened NT, 35 were found, and the Hammerhead Shark (Sphyrna lewini) with a status of very threatened CR, 15 were found. Of all the types of sharks caught, they were still juveniles and not yet suitable for catch.

Abstract

Respons fisiologi mata ikan selar (Selaroides leptolepis) dan ikan kembung (Rastroliger brachysoma) berbeda untuk setiap warna cahaya. Respons fisiologi mata ikan bisa dijadikan indikator dalam menentukan tingkat ketertarikan ikan terhadap warna cahaya tertentu. Penelitian ini bertujuan untuk mengidentifikasi tingkat ketertarikan ikan selar dan ikan kembung terhadap cahaya warna putih, kuning, hijau dan biru. Metode penelitian menggunakan metode percobaan yang dilakukan di bagan tancap. Sepuluh ekor ikan selar dan ikan kembung yang dibatasi dengan jaring diberi cahaya selama 30 menit. Sampel ikan yang telah diberi perlakuan cahaya diambil matanya dan dilakukan analisis histologi. Analisis data yang digunakan dalam penelitian ini adalah analisis regresi ukuran ikan, indeks sel kon dan kecepatan pergerakan sel kon. Hasil penelitian menunjukkan bahwa ikan selar sangat tertarik terhadap cahaya LED warna hijau dan biru, sedangkan ikan kembung tertarik terhadap cahaya warna biru. Rata-rata indeks sel kon ikan selar pada cahaya warna biru dan hijau adalah 77,3±7,4% dan 70,7±6,8%, sedangkan rata-rata indeks sel kon ikan kembung yang diberi cahaya warna biru adalah 79,9±2,0%. Kecepatan rata-rata pergerakan sel kon ikan selar yang diberi cahaya biru mencapai 0,0180±0,0028 μm/det, sedangkan ikan kembung dengan cahaya hijau adalah 0,0157±0,0018 μm/det. Berdasarkan hasil penelitian dapat disimpulkan bahwa ikan selar sangat tertarik terhadap cahaya warna hijau dan biru, sedangkan ikan kembung sangat tertarik terhadap cahaya warna biru.

Abstract

The technological status of bottom gillnet fishing gear (rampus net) and its fishing operation methods have not changed much in its development and tend to be static. This problem also occurs among rampus net fishermen in Palabuhanratu Bay, where there is a decrease in catch productivity. The technological innovation needed for rampus net fishing gear is the use of bait boosters to attract and gather fish so that they are easy to catch. The research activities were carried out using an experimental fishing method with 20 trips as replications by comparing between treatment of rampus net with the control. The results showed that there was an increase in catches in treatment of rampus net compared to the control. The catch consisted of 61.2% demersal fish and 38.8% pelagic fish, dominated by largehead hairtail fish. The productivity of the treatment of rampus net had a value greater than the control, namely 0.85 kg/net-piece and 0.50 kg/net-piece, respectively. The production margin of the catch of the rampus net treatment compared to the control was 70.5%. Key words: bait booster, bottom gillnet, Palabuhanratu Bay

Abstract

Handline fishermen in Palabuhanratu are small-scale fishermen who have limited access to science and technology. This condition has an impact on low catch productivity. Therefore, to overcome this problem, an effective fish collection technology is needed, namely the baited drift fish aggregating device (FAD). This study aims to construct a baited drift fish aggregating device operated by a handline fishing boat as a treatment handline, compare the composition of the catch, determine the effect of using baited drift fish aggregating devices, determine productivity and determine the production margin of the treatment handline catch compared to the control. The experimental fishing method was carried out with 16 trips as replications provided a higher catch result for the treatment handline compared to the control with a total catch of 98.67 kg and 62.34 kg, respectively. Based on the results of the Mann-Whitney analysis, the treatment handline had a significant effect on the number of fish and the weight of the catch. The productivity of the treatment handline had a greater value than the control handline, namely 6.17 kg/trip and 3.90 kg/trip respectively with the production margin of the treatment handline catch compared to the control for weight units and individual increasing by 58.28% and 76.2% respectively.
