Abstract

One of potential fishing grounds for small pelagic fish in Southeast Mallucas Regency is Rosenberg Strait waters. In this region, a study on the effect of different light intensities of floating lift net on fish catches was carried out. The analyses were done on light distribution of 4 light intensities different: Petromaks Lamp and Underwater Lamps of each 18 watt, 36 watt and 54 watt. This study showed that catches of floating lift net using different light intensities were statistically significantly different. The use of 36 watt and 54 watt underwater lamp yielded the same amount of catches but higher than that of 18 watt-underwater lamp and petromaks, both in number and species. Catches consisted of 17 species, 16 fishs and 1 mollusca. Number of species and size also varied with light intensity used. There were 13 fishs species dominated by Stolephorus indicus as much as 46.9 kg or 22% for petromaks catches, 14 fishs species dominated by Rastrelliger kanagurata as much as 64 kg (31%) for 18 watt underwater lamp, 17 fishs species dominated by Rastrelliger kanagurata as much as 76 kg (28%) for 36 watt underwater lamp, and 15 fishs species dominated by Stolephorus devisi as much as 54.8 kg (22%) for 54 watt underwater lamp, respectively. Based on the results, it is recommended that the use of light intensity in fishing operations of floating lift net should be 36 watt and 54 watt underwater lamps, due to high catches, both in number and species. Beside that, since light fishing has also caught illegal fish size, number of this fishing gear type should be controlled.

Abstract

Fishing using gill net has been done widely by fishermen in Southeast Maluku Regency, including in Ohoi Tuburngil waters north east Kei Besar District. Fishing activities using this type of fishing gear are still ongoing as a source of income for local community. The objective of this research were to (1) analyze the composition of the catch with a surface gill net based on the catching time and (2) compare yields and determine the best fishing time in the fishing process with surface gill net. The research methods were experimental fishing, observation and interview. The results showed that the total number of fish species caught with surface gill net during the research was 128 fish consisting of 7 fish species. The value of the diversity index (H') obtained for fishing in the morning was 1,60, at daytime was 1,15, afternoon was 1,30, and at evening was 0,92. According to the criteria for the diversity index, the value of H' less than 1 is categorized as low diversity. The results of the analysis of variance showed that te fishing time has a very significant effect on the catch number at the level of ά = 0.05. Based on the results obtained, it showed that the evening catch was significantly different from that in the morning, the daytime and the afternoon, while catch in the afternoon was significantly different from the day time and different from the morning time.

Abstract

Keberhasilan proses penebaran  dan penarikan  sangat dipengaruhi oleh beberapa faktor seperti spool rate, ballast sinking rate dan towing rate yang dapat mempengaruhi efisiensi dan keberhasilan operasi purse seine selain faktor teknis, faktor musim tangkap hubungan dengan bulan juga turut berpengaruh, berdasarkan pada gambaran  tersebut maka  kami melakukan penelitian dengan tujuan untuk : Menganalisis hasil tangkapan Purse Seine berdasarkan bulan yang berbeda yakni; bulan Oktober, November dan Desember di Perairan Teluk Ambon. Penelitian dilakukan dengan metode experimen dan data dianalisis menggunakan Uji hipotesis pada analisa data menggunakan uji t paired sample t test. Hasil tangkapan purse seine ada enam jenis ikan selama waktu pengamatan. Dari ke enam jenis ikan tersebut hanya ada empat jenis ikan yang dominan tertangkap yakni ikan Kawalinya (Selar boops) dengan total berat 12.359 Kg (27 %) diikuti Komo (Auxis thazard) berat 12.206 Kg (27 %),  ikan Lema (Rastrelifer brachysoad) 10.326 Kg (23%) serta ikan Momar (Decaptrus  macrosoma) 9.330 Kg (21 %). Hasil uji t sampel berpasangan dapat diketahui, bahwa perbandingan nilai sig 2 tailed berat total hasil tangkapan bulan Oktober-Nopember 0,00<0,05 yang berarti Ho ditolak, H1 diterima berarti kedua bulan tersebut berbeda dan bulan  Nopember-Desember nilai  sig 2 tailed berat total hasil tangkapan yaitu sebesar  0,986 > 0,005 yang berarti Ho diterima, H1 ditolak berarti kedua bulan tersebur tidak berbeda.

Abstract

Penangkapan ikan yang dilakukan oleh nelayan tidak selalu mendapatkan hasil yang sama setiap kali. Jumlah ikan yang berhasil ditangkap berbeda-beda tergantung pada waktu, meskipun usaha dan tempat penangkapan tetap sama. Nelayan umumnya menggunakan jaring insang di perairan dekat pantai atau di tengah laut untuk menangkap ikan kecil atau ikan besar yang hidup di laut lepas. Ikan akan menyenangi daerah yang kondisi perairan sesuai dengan daya adaptasi tubuhnya, banyak makanan, dan aman dari predator. tujuan adalah: menganalisis keragaman jenis tangkapan dengan jaring insang dasar , dan membandingkan hasil tangkapan jaring insang dasar berdasarkan air pasang dan air surut. Metode penelitian yang digunakan adalah eksperimental fishing atau percobaan penangkapan, observasi dan wawancara. Jenis hasil tangkapan bottom gill net selam 15 trip penangkapan diperoleh jumlah 115 ekor yang paling banyak tertangkap yakni jenis ikan Selangat (chacunda Gizzard Shad) dengan jumlah 55 ekor (47,8 %) dan paling sedikit tertangkap adalah jenis ikan Kerong kerong (Terapon jarbua) dan ikan Sebelah (Pleuronectiformes) (0,9 %), serta jumlah total hasil tangkapan pada saat air pasang 33 ekor (28,70 %%), sedangkan pada saat surut sebanyak 82 ekor (71,30 %). Hasil nilai indeks keanekaragaman jenis (H’) yang diperoleh untuk penangkapan pada waktu air pasang sebesar 1,52, untuk penangkapan pada waktu air surut nilai (H’) sebesar 1,38, Menurut kriteria nilai indeks keanekaragaman yang ditetapkan oleh Shannon - Wiener yaitu H’ lebih kecil 1 maka nilai indeks keanekaragaman termasuk keanekaragaman rendah. Berdasarkan hasil uji paired sampel t-test dapat diketahui, bahwa nilai sig 2 tailed yaitu sebesar 0,337>0,,05 yang berarti Ho diterima, H1 ditolak artinya tidak ada perbedaan antara operasi penangkapan saat air pasang dan air surut.

Abstract

Hand line is a type of fishing gear that is active and environmentally friendly and is often used by traditional fishermen to catch fish with high economic value. The right bait is one of the factors for maximizing catches. Fishermen around the village of Fiditan, Jellyfish Island, Kota Tual generally use various kinds of bait, such as Momar fish (Decapterus sp), Sikuda fish (Letrinus lenca) and Nipah worms (Namalycastis). This research was held in November – December 2022. The objectives are: to know the composition of hand line catches with different baits and to determine the type of bait that gives the most catches. This research is expected to provide information and knowledge to fishermen about hand line fishing gear units using different baits. Data analysis used a randomized block design, with baits used were Momar fish, Sikuda fish and Nipah worms. During the study, a total of 346 fish were caught consisting of Sikuda fish (Letrinus lenca) with a total of 294 fish (85.5%), followed by Gora fish (Lutjanus carponotatus) 25 individuals (7.33%), Sand-sand fish ( Taeniura ymma) 20 individuals (1.16%) and the smallest catch was Gace fish (Lutjanus malabericus) with a total of 1 fish (0.29%). The results of the analysis of variance showed that the Fcount for the treatment (8.66) was greater than the Ftable (0.05); 14:2) (88.5) so statistically H0. This means that the difference in the use of bait has a very significant effect at the level of ά = 0.05 on the catch. The BNT test results also showed differences in the value of each bait so that it was concluded that the three baits used by fishermen had a significant difference in the catch obtained with Sikuda bait with the highest yield, followed by Nipah worm and Momar fish bait.

Abstract

Cahaya lampu merupakan alat bantu penangkapan dalam operasi penangkapan ikan yang berfungsi untuk menarik ikan dan memfokuskannya pada area penangkapan. Penggunaan cahaya lampu yang efektif dan efesien dapat meningkatkan hasil tangkapan dan menurunkan biaya operasional penangkapan ikan khususnya pada perikanan bagan apung. Teknologi cahaya lampu celup bawah air yang dikembangkan praktisi perikanan saat ini sangat efektif dan efesien digunakan nelayan kecil di perikanan bagan apung, namun sampai saat ini teknologi tersebut belum dapat digunakan oleh seluruh nelayan kecil di Indonesia karena keterbatasan kemampuan dalam mengoperasikan alat bantu penangkapan tersebut. Tujuan PkM adalah memberikan pengetahuan dan ketrampilan penggunaan lampu celup bawah air (Lacuba) dalam kegiatan penangkapan ikan pada perikanan bagan apung. Metode yang digunakan dalam PkM adalah pelatihan dengan materi teori dan praktik. Materi teori terkait dengan konsep lampu celup bawah air dan manfaat ekonomisnya. Materi praktik mengenai aplikasi lampu celup bawah air pada bagan apung. Peserta pelatihan berjumlah empat belas orang yang merupakan nelayan kecil bagan apung Ohoi Selayar. Kegiatan pelatihan tersebut berjalan dengan baik dan lancar dan hasil evaluasi menunjukan bahwa sebagian besar nelayan kecil yang mengikuti pelatihan tersebut sangat memahami materi yang disampaikan dan terampil dalam mengoperasikan  Lacuba sebagai alat bantu penangkapan ikan pada bagan apung.
