Abstract

Fisheries should be a sustainable economic activity in order to maintain its services in the future. Sustainable marine fisheries resources exploitation requires a utilization rate lower than the resources availability. Therefore, the exploitation rate should not achieve the recovery ability of the resources in any particular period. In fishing activities, for instance, there is a guideline not to catch fish over the Total Allowable Catch (TAC), 80% of the MSY value. The exploitation rate of the anchovy (Stolephorus sp.) in Dodinga Bay was still low. It could result from small-scaled traditional fishermen and low fishing distance from the shore. Their income was also low due to high operational cost and fluctuation in fish price. To improve the fishermen prosperity, it is necessary to raise the fishing productivity and the efficiency of production input utilization on the boat lift net. This study focused on understanding the anchovy fishing season of the boat lift net in Dodinga Bay to analyze the yearly fishing seasons for the last five years. Results concluded that the fishing season of the anchovy (Stolephorus sp.) in Dodinga Bay could be separated into two phases, March to June and October to November, but the former was more extensive and lager in scale than the later.

Abstract

Information about oceanographic conditions is important to determine the fertility level of waters. Oceanographic parameters in water can be influenced by global climate factors, one of them is the ENSO (El Niño Southern Oscillation) phenomenon. There have been many studies on the effect of ENSO phenomenon on oceanographic variability, but no studies have been carried out in the waters of North Sulawesi. This study aims to determine the effect of the ENSO phenomenon on the variability distribution of oceanographic parameters in North Sulawesi waters. The data used for this study were Sea Surface Temperature (SST) and chlorophyll-a from the AQUA-MODIS imaging results, wind reanalysis results from ECMWF, and Nino 3.4 index as an indicator of ENSO from NOAA. The data were processed and analyzed using quantitative analysis methods in the form of graphics. The results showed an indirect effect of the ENSO phenomenon on SST parameters and chlorophyll-a. This is because the effect of the ENSO phenomenon occurred in a certain period:  when strong El Niño triggered low temperatures of sea surface and high chlorophyll-a, and when La Niña was strong it triggered high temperatures of sea surface and low chlorophyll-a. Meanwhile, the wind speed pattern showed an insignificant effect because the wind speed was still dominated by the influence of the monsoon pattern.Indonesian title: Hubungan antara El Niño Southern Oscillation (ENSO) dan parameter oseanografi di perairan Sulawesi Utara

Abstract

Covid-19 pandemic has implications for all aspects of fishery activities in Indonesia, one of them is negative impact on the supply chain of the fishery business. To find out more about this impact, the study was aimed to determine the condition, in general, of tuna capture fisheries in the Talaud Islands Regency before and during the Covid-19 Pandemic, and to find out the comparison of operational costs and production of fresh tuna at the level of fishermen and intermediary traders in the area in both periods. Data collection was carried out in April 2020 to March 2021. Three districts in the area were selected as research locations, namely Salibabu, Gemeh, and South Essang. Surveys using questionnaires were conducted on respondents at predetermined locations. Comparative analysis using t-test was applied in this study. The results showed that the pandemic has caused, among other things, a decline in fish prices, effect in community's economy, and a decrease of tuna production. Tuna production is particularly important because while it affected the production, the operational costs remained constant. This occurs at all levels, both at the level of fishermen and at the level of intermediary traders. It can be concluded that the Covid-19 pandemic has had an impact on fresh tuna fishing activities in the area where fresh tuna production has decreased and tuna buying traders are not operating. In particular, the operational costs of catching tuna at the fisherman's level are the same, both before and during the pandemic. Meanwhile, tuna production has decreased dramatically during the pandemic. This also happens at the level of intermediary traders.Indonesian title: Komparasi biaya operasional dan produksi produk tuna segar pada masa sebelum dan selama Pandemi Covid-19 di Kabupaten Kepulauan Talaud, Provinsi Sulawesi Utara

Abstract

Taman Nasional Bunaken (TNB) is located in North Sulawesi Province, Republic of Indonesia. TNB offers an exploration experience of marine tourism such as snorkeling and diving. This study was conducted to determine the statistics and correlation of weather parameters on hydrodynamics in the waters of the small island of TNB. This information can be used by marine tourism users. The weather data studied are wind direction and speed. The hydrodynamic conditions studied were wave height and ocean currents. Respondent surveys were also conducted on tourist users at the research sites. The wind direction for the period January - April is dominant from the Northeast, May - September is dominant from the East to the South, October tends to be evenly distributed from the East to the West, and November - December is dominant from the West. Significant wind speeds that occur in January, February, and March range from 18 – 36 knots. The average wave height shows a significant value in January – March, tends to be lower in April – June, fluctuates in July – November, and increases again in December. The maximum current velocity at a sea depth of 16.5 m is stronger than the maximum speed at a depth of 0.5 m and 8.0 m in January – April, and May August. The correlation value of wind speed and sea wave height is significant at 0.96 and the correlation between wind speed and the current speed is 0.74. These results indicate that there is a strong -very strong relationship between parameters. The survey results show that wind speed, wave height, and ocean currents have the same pattern. January, February, November, and December are the months of extreme or bad weather and hydrodynamic conditions.Keywords: Taman Nasional Bunaken, Weather, Hydrodynamics, CorrelationAbstrakTaman Nasional Bunaken (TNB) terletak di Provinsi Sulawesi Utara, Negara Republik Indonesia.
