Abstract

This research aims are to determine the potential fishing grounds of yellowfin tuna based on the approach of sea surface temperature, chlorophyll-a and catches in the Ceram Sea. Overall catches of 407 Individuals. In January the total catches were 66 individuals (14.44%), in February 67 individuals (14.66%), in March 84 individuals (18.38%), in April 116 individuals (25.38%) and in May 124 individuals (27.13%). The distribution of sea surface temperature and chlorophyll-a in the Ceram Sea in January-May 2019 looks varied. In January the average sea surface temperature was 29.13 oC, in February sea surface temperature was 29.54 oC, in March sea surface temperature was 30.12 oC, in April sea surface temperature was 30.12 oC, in May sea surface temperature was 29.77 oC. Chlorophyll-a concentration in January and February was 0.21 mg/m3, March was 0.20 mg/m3, April was 0.16 mg/m3, and May was 0.25 mg/m3. The results of the t-test analysis showed the P-value of sea surface temperature was 0.009<0.05, chlorophyll-a P-value 0.00048<0.05. Determination of potential fishing areas based on sea surface temperature, chlorophyll-a, and CPUE indicators shows that potential fishing areas are found in January, February, March, and May, while in April are in the medium potential category. Penelitian ini dilaksanakan dengan tujuan menentukan daerah penangkapan potensial Tuna madidihang berdasarkan pendekatan suhu permukaan laut, klorofil-a dan hasil tangkapan di Laut Seram.  Secara keseluruhan hasil tangkapan ikan tuna madidihang sebanyak 407 Individu. Bulan Januari total hasil tangkapan sebanyak 66 individu (14.44%), bulan Februari 67 individu (14.66%), bulan Maret 84 individu (18.38%), bulan April 116 individu (25.38%) dan bulan Mei 124 individu (27.13%). Sebaran suhu permukaan laut dan klorofil-a di Laut Seram pada bulan Januari-Mei 2019 terlihat bervariasi. Bulan Januari rata-rata suhu permukaan laut sebesar 29.13 oC, bulan Februari suhu permukaan laut 29.54 o, bulan Maret suhu permukaan laut 30.12 oC, bulan April suhu permukaan laut 30.12 oC, bulan Mei suhu permukaan laut 29.77 oC. Konsentrasi klorofil-a pada bulan Januari dan Februari sebesar 0.21 mg/m3, bulan Maret sebesar 0.20 mg/m3, bulan April sebesar 0.16 mg/m3, dan bulan Mei sebesar 0.25 mg/m3.  Hasil analisis uji t menunjukan nilai P-value suhu permukaan laut sebesar 0,009<0,05, klorofil-a P-value 0,00048<0,05. Penentuan daerah penangkapan ikan potensial berdasarkan indikator suhu permukaan laut, klorofil-a dan CPUE menunjukkan daerah penangkapan ikan potensial terdapat pada bulan Januari, Februari, Maret, dan Mei, sedangkan pada bulan April berada dalam kategori potensial sedang.

Abstract

Yellowfin tuna is an important economic commodity that is widely exploited with various fishing tools and methods and catches of various sizes. This study aims to describe yellowfin tuna fishing units and analyze the size distribution and productivity of yellowfin tuna resources based on seasons in the waters of the Tanimbar Islands. This research was carried out in the waters of the Tanimbar Islands from August 2021-March 2022. Data were collected through interviews, observations and measurements of the length and weight of the catch and analyzed descriptively and CPUE analysis. The results showed that catching yellowfin tuna in the waters of the Tanimbar Islands was classified as a small-scale fishery, using hand fishing gear with boat sizes under 10 GT. Yellowfin tuna caught in the waters of the Tanimbar Islands throughout the year are dominated by small size fish that are still classified as juveniles. The presence of large-sized tuna was more in the first transitional season with an attendance percentage of 21.98%. The abundance of yellowfin tuna resources in the waters of the Tanimbar Islands fluctuated according to the seasons, and the highest abundance was found in the transitional season one. ABSTRAK Ikan tuna madidihang merupakan komoditas ekonomis penting yang banyak dieksploitasi dengan berbagai alat dan metode penangkapan serta hasil tangkapan yang beragam ukurannya. Penelitian ini betujuan untuk mendeskripsi unit penangkapan tuna madidihang dan menganalisis distribusi ukuran serta produktivitas sumberdaya ikan tuna madidihang berdasarkan musim di perairan Kepulauan Tanimbar. Penelitian ini dilaksanakan di perairan Kepulauan Tanimbar sejak Agustus 2021-Maret 2022. Data dikumpulkan melalui wawancara, observasi dan pengukuran panjang dan berat hasil tangkapan, kemudian dianalisis secara deskriptif serta analisis CPUE. Hasil penelitian menunjukkan bahwa penangkapan ikan tuna madidihang di perairan Kepulauan Tanimbar tergolong perikanan skala kecil, menggunakan alat tangkap pancing tangan dengan ukuran kapal di bawah 10 GT. Ikan tuna madidihang yang tertangkap di perairan Kepulauan Tanimbar sepanjang tahun didominasi ikan ukuran kecil yang masih tergolong juvenile. Kehadiran ikan tuna ukuran besar lebih banyak pada musim peralihan satu dengan persentasi kehadiran sebesar 21,98%. Kelimpahan sumberdaya ikan tuna madidihang di perairan Kepulauan Tanimbar berflutuksi menurut musim, dan kelimpahan tertinggi didapati pada musim peralihan satu Kata kunci: Distibusi ukuran, kelimpahan, musim, pancing tangan, tuna madidihang

Abstract

Exploitation of squid by fisher’s on the southern coast of Ambon Island uses simple fishing technology with modifications based on fisher's experience. This study aims to describe tools and fishing methods, fishing seasons and areas, as well as analysis of production and income of squid fishing in the southern waters of Ambon Island. Data was collected through experimental fishing for 21 trips for each fishing gear and analysis was carried out descriptively and analysis of costs and income. The results showed that the use of a scoop net is one of the fishing gear that is not found elsewhere, while the jigger used has been modified by using underwater lights. Fishing areas in coastal areas with a distance of about 1 nautical mile. Data collection was carried out during the fishing season in September-December. Scoop net productivity is 49.5 kg/trip, and labor productivity is 16.5 kg/person/trip. Jigger production is 509.88 kg and labor productivity is 24.28 kg/person/trip. The net profit of each fisher’s per month from scoop and jigger are Rp.3,025,250 and Rp.2,665,000, respectively
