Abstract

The main problem facing by fishermen for capturing skipjack tuna is limited information of potential skipjack fishing areas such as the frontal locations. The purpose of this study was to analyze the spatial and temporal skipjack tuna distributions and thermal fronts, and to determine the effect of climate change on their distribution and abundance during transitional seasons. We used a survey method, in which catch and fishing position data were collected by following pole and line fishing operations. This study also collected secondary data that consisted of sea surface temperatures (SSTs) and chlorophyll-a derived from Aqua / MODIS. Fronts were determined by calculating SST gradient, SSTs preferences, chlorophyll-a, bathymetry and distance from coastline, whereas SST anomaly was calculated from the difference between monthly SST and mean SST. We mapped satellite and field data using ArcGIS 10.0. The results showed that the highest catch of skipjack tuna with an average of 205 fish/set were found inOctober 2013, which occurred in the areas of 4 o40S-5o10S and 120o40E-121oE. The locations had a temperature gradient of 0.4oC and chlorophyll-a density from 0,15 to 0,23 mg m-3. Potential fishing areas may associate with negative SST anomalies of -2.1373 - -0.6469oC, reflecting that skipjack tuna tend to be at thermal fronts with relatively lower SST compared with an average of seven years.

Abstract

ABSTRAKTeluk Bone-Laut Flores merupakan salah satu daerah potensial penangkapan ikan cakalang terbaik di Indonesia timur.  Perairan tersebut menjadi target utama operasi penangkapan bagi nelayan pole and line. Tujuan penelitian ini adalah untuk mendeskripsikan karakteristik daerah potensial penangkapan ikan tersebut menggunakan data suhu permukaan laut (SPL) dan klorofil-a pada periode Januari-Juni 2014.  Penelitian ini menggunakan metode survei dengan mengumpulkan data hasil tangkapan dan posisi penangkapan setiap kali melakukan kegiatan penangkapan.  Data SPL dan klorofil-a dari citra satelit Terra/MODIS kemudian diekstrak dari lokasi penangkapan ikan cakalang untuk mempelajari kondisi oseanografi yang sesuai dengan keberadaan ikan tersebut.  Hasil penelitian menunjukkan bahwa hasil tangkapan ikan cakalang tertinggi didapatkan pada bulan Mei yaitu sekitar 138 ekor/setting.  Hasil tangkapan tersebut bersesuaian dengan kondisi SPL berkisar antara 29,75°C dan 30,25°C dan konsentrasi klorofil-aantara 0,125 dan 0,213 mg m-3.  Kenyataan ini menunjukkan bahwa kedua faktor oseanografis tersebut menjadi indikator penting untuk memahami dinamika spasial pergerakan dan konsentrasi ikan cakalang di Teluk Bone terutama pada periode Januari-Juni.

Abstract

Large pelagic species such as tuna are known to be abundant in Mamuju Waters,  Makassar Strait.  The distribution and abundance of the fish in that area are expected to be  related to the distributions of sea surface temperature and chlorophyll-a concentration. This study aims to predict spatial and temporal distribution of the species during the period of June 2013-May 2014.  Probability indices used for detection of tuna potential fishing zones (PFZs) were constructed from a model of satellite-based SST and chlorophyll data in relation to tuna fishery. Results showed that the occurrence of tuna species in Mamuju Water were mostly predicted in areas of 118°12’-118°48’ E 1°48’ – 2°30’S with the total area of approximately 7,495 km2.   The potential fishing zones were mainly found in August.  It was likely that tuna potential fishing zones associated with the preferred oceanographic factors throughout the study area.

Abstract

The distribution of anchovies (Stelophorus spp) in the Spermonde coastal waters, Pangkep, was studied from satellite remotely sensed environment and catch data, using Geographic Information Systems (GIS) and Generalized Additive Model (GAM). The goal of this preliminary study was to investigate the relationship between sea surface temperature (SST) and sea surface chlorophyll-a concentration (SSC), and anchovies distribution. To describe their relationship, SST and SSC derived from Aqua/MODIS satellite were overlain with the positions of experimental fishing by local fishermen’s lift net (“Bagan perahu”). The experimental lift net operations were conducted in April to May 2008. The findings of this study showed that most of the anchovies distribution occurred in the coastal area. Anchovies distribution tended to be highest in the specific temperature of 28.8 - 29.3C and chlorophyll-a of 1.5 ‒2.5 mg.m . Furthermore, the SST and SSC in the coastal waters of Spermonde play a great role in determining the variability of the anchovies quantitative distribution in the study area. The results were supported by GAM prediction.  Due to lack of robust data, there is no detailed information on the optimum habitat preference of anchovies. Future work is needed to reveal the preferred habitat of anchovies with the consideration of more oceanographic parameters.

Abstract

Tujuan penelitian ini adalah untuk menentukan zona potensial ikan cakalang melalui idetifikasi daerah thermal dan klorofil-a front dengan menggunakan metode Single Image Edge Detection (SIED). Kegiatan peneletian ini dilaksanakan di perairan Seram dari bulan Maret – Mei 2015. Dukungan data hasil tangkapan pada tahun 2011 dan 2012 diperoleh dari pelabuhan perikanan Ambon. Suhu permukaan laut (SPL)  dan  klorofil-a  permukaan  laut  diakses  dari  satelit  MODIS  dengan  sensor Terra (MODIS-Terra). Hubungan   antara   kondisi   oseanografi   dengan   hasil   tangkapan   cakalang   ditentukan   dengan menggunakan program R   dengan model statistik Generalized Additive Model (GAM) dan kemudian dilanjutkan dengan identifikasi front melalui SIED Algorithm. Hasil penelitian ini menunjukkan bahwa ikan cakalang cenderung terkonsentrasi pada musim transisi timur-barat dalam tahun 2011, 2012 and 2015 dalam kisaran masing-masing SPL sebesar 29,50 – 30,00 °C dan klorofil-a  sebesar  0,10 – 0,20 mg/m3.

Abstract

Tujuan penelitian ini adalah untuk mendeskripsikan profil sebaran suhu permukaan laut (SPL)  dan  klorofil-a  di  daerah  penangkapan  ikan  teri  pada  periode  Juni-September  2014. Kegiatan penangkapan ikan dilakukan dengan mengunakan bagan rambo dengan fishing base di Tempat Pendaratan Ikan Ponrang. Hasil tangkapan dan posisi penangkapan ikan dikumpulkan pada setiap kali melakukan kegiatan penangkapan. Data SPL dan klorofil-a dari citra satelit Terra/MODIS kemudian diekstrak dari semua posisi penangkapan ikan teri.  Hasil penelitian ini menunjukkan  tangkapan tertinggi pada  sebaran SPL  dan densitas klorofil-a  masing-masing sekitar  29,0  sampai  29,5  °C  dan  0,45  dan  0,75  mg  m-3.    Kenyataan  ini  terungkap  bahwa parameter  oseanografi     yang  dipilih  merupakan  indikator  yang  baik  dalam  menjelaskan distribusi ikan teri di Teluk Bone.
