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

The economic profit of mini purse seine fishing business in the coastal area of the Kei Islands is different in every season and fishing ground. The aim.of.this analyze the profit of the mini purse seine fishing business on every season and on fishing grounds. Collecting data using survey methods, determining respondents using purposive sampling. Data were analyzed using fishing ground analysis and economic analysis. The results of.the identification indicate that during the transitional season 1 and west, the mini purse seine fishing ground are located on the eastern coast of Tayando and eastern Kei Besar coast and the Nerong strait. The result of the identification shows that the fishing grounds of mini purse seine in the western and transitional 1 seasons in the waters of the eastern Tayando Island, the Nerong Strait, and the waters of the eastern Kei Besar Island, while at the beginning of.the east monsoon in the waters of.the eastern part of Tayando Island and the Nerong Strait.The.results.of.the.economic.analysis.show.that the fishing grounds waters of.the eastern Tayando Islandhaves higher economic profit in each season because it has low efficiency, effectiveness, productivity, and high business profit. Fisheries managers in Maluku Province need to work together with fishermen to regulate production inputs in the fishing grounds of the Nerong Strait every season.

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.
