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 purpose of this study was to characterize potential fishing ground for the skipjack tuna using the oceanographic conditions of sea surface temperature and chlorophyll-a concentrations and catch data, and to describe the level of primary productivity around the skipjack fishing grounds in the Bone Bay. This study used a survey method by collecting primary tuna catch and MODIS satellite image data. The data were analyzed using Empirical Cumulative Distribution Function (ECDF). The model outputs were visualized using ArcGIS spatial analyst.  The results showed that the potential skipjack tuna fishing grounds during the west monsoon ( December -February ) were well characterized  by  the environmental conditions of SST and chlorophyll- a concentration ranged from 29.9 to 31.0 °C and from 0.12 to 0.22 mg m3, respectively. The highest catches for skipjack were found in February in the specific areas of 120°E121°E and 3°S-4°S where the levels of primary production ranged from 5.30 to 11.62 g C/m/ month during the west monsoon.

Abstract

Perairan Teluk Buyat memiliki topografi dasar yang kompleks, dengan terumbu buatan (reef ball) yang ditebarkan oleh PT Newmont Minahasa Raya sekitar 10 tahun  yang lalu. Oleh karena itu alat tangkap yang dapat dioperasikan di daerah itu hanya terbatas pada pancing dasar.  Tujuan penelitian ini adalah adalah untuk mengetahui status perikanan tangkap pancing ikan dasar dan membuat peta tematik lokasi penangkapan.Penelitian ini dilaksanakan di sekitar Teluk Buyat Kecamatan Ratatotok Kabupaten Minahasa Tenggara, selama 7 bulan yang diawali dengan tahap perencanaan sampai dengan penulisan laporan. Penelitian ini dikerjakan dengan menggunakan metode survei yang didasarkan pada pendekatan deskriptif. Tertangkap sebanyak 96 jenis ikan dasar dengan tangkapan yang dominan sebanyak 12 jenis, yaitu Bobara buliling dan biru (Carangoides gymnostethus), bobara pongko (Carangoides fulvoguttatus), bobara kotak, kuning dan wayan (Carangoides ferdau), bobara napo dan bobara lao (Citula armatus), bobara mopi (Caranx ignobilis), bobara sangkalade dan sangkapete (Carangoides uii) dan bobara sepo (Seriola dumerili). Semua jenis ikan tertangkap dengan pancing dodango.Musim penangkapan ikan dasar terjadi selama tujuh bulan dalam setahun, yaitu pada bulan Januari dan Maret, kemudian pada bulan Mei hingga Juli dan bulan Nopember serta Desember. Tangkapan maksimum yang lestari dilakukan sebanyak 25 trip per hari dengan jumlah tangkapan sebanyak 152 ekor.  Rata-rata tangkapan berukuran berat 1,5 kg dengan demikian biomassa sebesar 228 kg per hari. Bila per kg tangkapan sebesar Rp. 10.000,- maka setiap nelayan mempunyai pendapatan sebesar Rp. 90.000,- per hari. Ikan dasar tertangkap di sekitar perairan Buyat dengan lokasi-lokasi napo yang ada dengan kisaran kedalaman antara 30 hingga 80 meter.

Abstract

Biological performance of skipjack tuna has been done in the Flores Sea during the  southeast monsoon (June - August, 2013).  The objective of the research was to analyze biological performance of skipjack tuna captured by purse seine: including size composition,age classes, growth rate, food habit, gonad maturity and suitable length for capture.  The data for length structure and age class, the growth rate,  food habit, gonad maturity,  and volumetric fecundity estimation were analyzed using Bhattacharya, Von Bertalanffy, propendance index, histological and volumentric methods, respectively. The results showed that (1) the size structure and age class were different according to the fishing ground location and the fishing season, (2) the average size of fishes captured in the western part of Flores Sea was greater than the eastern one, (3) the average length of fishes catched by purse seine without fish aggregation device (FAD, rumpon) was longer than  that of with FAD, (4) the growth rate of skipjack tuna was slow where the growth coefficient was less than 0,5 per year, and the asymptotic length was 106,0 cm FL, (5) the skipjack tuna achieved the mature stage at 45 cm and  at 50 cm length for female and male, respectively, and ready to spawn at 55 cm and 60 cm for male and female , respectively, (6) it was more than 80 % of fishes captured by fishermen in the Flores Sea which were not yet suitable size for fishing.

Abstract

The research was aimed at determining the effect of fishing techniques, handling facilities and method son the quality of the catch. The research employed four types of fishing gears, i.e. purse seine, cantrang,gillnet and boat-liftnet with five replicates each. Five species of the dominant catch were taken for qualitydetermination on-board, at landing sites, and after auctioning. The condition of handling facilities andmethods were evaluated. Fish transit time (time lapse between the fish lifting and auction process) was also determined. Results indicated that the fish quality decreased as the transit time increased. Nearly all fish caught were subjected to neither good handling nor low temperature despite the availability of good handling facilities. Nevertheles, the fish quality remained fairly good up to the point of soon after auctioning (pH’s<7 and organoleptic scores >7). When alone, none of the quality predictors affected the fish quality. However, when the fishing techniques were compounded the quality predictors significantly affected the fish quality. Regression analysis showed that, when the fishing techniques were uncompounded, 73.96% of the fish quality was determined by fishing with purse seine, cantrang, boatliftnet and fish transit time. When fishing techniques were compounded,however, the fishing techniques, on-board handling methods, on-board and on landing site handling facilities, and the fish transit time contributed 73.96% effect to the fish quality. The PCA analysis showed that as much as 52.52% and 27.27% the fish quality were determined by the purse seine and cantrang, respectively.

Abstract

Fisheries management ideally could prevent the occurrence of overfishing which nowadays has occurred globally, including in Indonesia.  On the basis of fishing status and biology of skipjack tuna, as well as analysis of relationship between sea surface temperature and chlorophyll-a with skipjack tuna catches,  the fisheries management should implement zoning regulation. The north zone was suggested to be prioritized as a conservation area for protecting skipjack juvenile (< 46,5 cm FL) from fishing activity.  The middle and south zones were suggested to be fishing area where sustainable fishing is applied.  The Application of these regulations has an implication on total allowable catches from Bone Bay.  The number has lower value than the previous MSY and F-opt values.  Number of skipjack tuna which was allowed to be caught in the north zone is 573 ton yr -1 , in the middle zone was 5,820 ton yr and in the south zone was 2,210 ton yr -1 .   Overall, the value of allowed number of skipjack tuna catches in Bone Bay was estimated to be 8,600 ton yr effort per year is equivalent with 5,376 operational trips from pole and line boats.   -1 with fishing-1

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

The study, in 2012, has successfully formulated with the MCDM for each allocation of  space in KKPD allotment (core areas, sustainable fisheries zone, used zone, and other zones). This weighting techniques need to be tested and  be implemented in identifying and designing the KKPD in the study area. This study aims to identify and map the biophysical conditions and the potential of coastal and marine natural resources in marine conservation area candidate, North Luwu Regency; to identify the areas suitable for the KKPD based on weighting technique with the MCDM method; and to evaluate potential candidates for marine protected areas in the coastal region. This study used a survey method to perform in  situ measurements of physico-chemical parameters, conducted a survey of coastal ecosystems using the transect method. The socio-economic data of coastal communities were collected using the questionnaire. The biophysical conditions and marine resources were analyzed using descriptive statistical methods. The results showed that the candidate region has a rich diversity  of coastal ecosystems, but the ecosystem, particularly seagrass beds and coral reefs have been in damaged category. Only the mangrove ecosystem that was still in a good condition category with moderate-to-heavy levels of density. There were 6 species of seagrasses and 6 species of mangroves and 71 species of reef fish. It was discovered 2 regions  corresponding to the allotment of the Core Zone, which is in the Region I and III with the total area of 654.22 hectares. For sustainable fisheries zone, Region  II and IV would be the first choice with the total area of 620.27 hectares. The Used Zone was identified in the Region V with total area of 480.66 hectares. The total area of the region was equal to 1755.15 hectares. Marine protected areas of was suggested to the protection of coastal ecosystems including mangroves, seagrass beds, and coral reefs and its associated biota, especially the protection of local feeding ground of several species (sea turtles and dugongs).

Abstract

Fishing is one of the most challenging activities in the world. It is about 80% of ship accidents due to human error. The availability and proper use of safety equipment can minimize the risk. This study aims to identify the suitability of safety equipment used on Slerek boat in PPN Pengambengan, Bali in accordance with international and national standards, and describes the role of relevant institutions to increase the fishermen safety. In this study, we used a survey method, in which focussed on three main aspects including  the types of safety equipment, numbers of safety equipment, and the suitability of equipment which must be taken. The lack of equipment and awareness about safety, and do not comply with the national standards for boat less than 24 meters length will directly affect the fishermen safety. The lack of regulations on the small boat safety showed that the fishermen safety in fishing activities in Indonesia have not been considered and there is no clear policy from local and central government.
