Abstract

This study aimed to investigate the relationship between the dinamic oceanographic condition and fluctuation in the catch of small pelagic fish. Study on the dinamic oceanographic conditions were focused on the sea surface temperature (SST), chlorophyll-a concentration (SSC) and water depth. The study took place in the area of Gulf of Bone located, data collection was started from April to September 2017. The data were collected using experimental fishing metode (large liftnet) and applications of remote sensing in satellite oceanography, which then analysed using Geographic Information System (GIS) dan Generalized Additive Models (GAMs). The result showed that the distribution of small pelagic fish tends to be within the area of temperature ranging from 29.5 to 30.0oC, the chlorophyll-a from 0.7 to 0.9 mg.m-3 and concentrated within the coastal area with in waters depth maximum of 100 m.Keywords: Oceanography, small pelagic fish, distribution, fishing ground, Gulf of Bone

Abstract

The skipjack tuna (Katsuwonus pelamis) resource in Bone bay has long been exploited, but information about the sustainable potential of this fish resource in Bone bay waters is still very limited. The aim of this research is to estimate potential of fish resources that include catch per unit effort (CPUE ), the maximum sustainable yield (MSY), optimum effort, exploitation rate and total allowable catch (TAC) of skipjack tuna in the waters of Bone bay. This study uses time series data, namely annual data from the fisheries statistics report at Marine and Fisheries Service, South Sulawesi Province from 2006-2015. The method used to estimate the potential of fish resources in this study is the surplus production method with the Schaefer model. The results showed that the average production and standard efforts in the 10-year period were 14689.7 tons and 914 standard units respectively. The estimation results obtained MSY and optimum effort per year are 22561.4 tons and 1730 standard units, and allowed catches (TAC) of 18049.2 tons per year. The level of exploitation of skipjack tuna resources in the waters of Bone Bay does not over exploited every year except in 2017.Keywords: potential of fish resources, skipjack tuna (Katsuwonus pelamis), MSY, TAC, Bone bay

Abstract

This study aimed to map the oceanographic conditions and, based on that, to determine the favorable condition of skipjack tuna fishing ground in Fisheries Management Area (FMA) 713. This condition includes sea surface temperature (SST) and chlorophyll-a concentration. The primary data, such as fishing ground position and fish catch per trip, was collected by following the fishing operations that utilized pole and line (in Bone Gulf and Flores Sea) and purse seine fishing operations (in Makassar Strait). The secondary data, such as SST and chlorophyll-a, was derived from oceanographic satellite image data. The result showed that from January to August 2019, the skipjack tuna tends to occupy off shore areas where the sea surface temperature is between 29 - 29.5 oC and the chlorophyll-a density is between 0.10 to 0.15 mg.m3.

Abstract

This study aims to identify main facilities and determine the level of the main facilities utilization of Birea fish landing base, Pa'jukukang District, Bantaeng Regency. The research was conducted from May to July 2020. The method used in this research is a case study. Primary data was consisting of the length of the pier, the distance between ships, the length of time to moor, the length of the breakwater and the length of the trip, and the size and number of ships anchored, were collected through direct observation in the field. Meanwhile, secondary data such as catch production data, development of the number and types of fishing units, the size of the port pool area, and the depth of the waters were taken through the interviews method. The utilization rate of the main facilities utilization of Berea fish landing base are a pier utilization rate of 90.5%, a port pool of 72.5%, a land port 86%, and two meters of water depth are required. Based on the research results, it is found that the long pier is still possible to accommodate ships that are anchored, while the port pool and portland still meet the requirements, however, dredging is necessary for dredging the depth of the waters for shipping in and out of ships. Key words: birea fish landing base, the level of main facilities utilization, bantaeng regency.

Abstract

The Makassar Strait waters area is a potential area for the utilization of marine fishery resources in Indonesia especially for large pelagic fisheries because it is one of the migration trajectories of little tuna (Euthynnus sp.). In order to optimally utilize tuna resources, remote sensing technology based on oceanographic satellite imagery can be relied upon to facilitate identification, prediction, and spatial and temporal mapping of potential fishing areas. This study aims to study the phenomenon of oceanography (thermal front) as an indicator of potential for little tuna fishing areas in the Makassar Strait. Primary data was obtained through in-situ data collection (direct observation in the field by following fishing operations using the purse seine, while secondary data consisting of oceanographic data such as sea surface temperature and sea surface chlorophyll-a concentrations sourced from satellite imagery data (Aqua satellite with MODIS sensor). The distribution of the thermal front was analyzed using ArcGIS 10.4 software to determine the relationship between little tuna fishing productivity and the oceanographic phenomenon. Based on the analysis results, total of 61 positions for little tuna fishing using a purse seine, five (5) fishing positions were in the thermal front area, where the catch of little tuna is higher than the average catch outside the area. These results indicate that the thermal front can be used as an indicator of potential for little tuna fishing areas in the Makassar Strait.

Abstract

Blue economy is a management system for all aquatic ecosystem resources, including marine and terrestrial ecosystems, related to economic value, sustainability of ecosystems and production resources, and distribution of benefits. The adoption of this concept in Indonesia uses the term inclusive and sustainable blue economy to emphasize the equitable distribution of benefits from the development of the blue economy by ensuring the sustainability of its carrying capacity. This paper explains the importance of managing Indonesian fisheries resources based on the blue economy concept to ensure the sustainability of existing fisheries resources. The literature study method issued by agencies and strategic stakeholders is the primary reference in this study. In this study, it was found that the significant challenges faced were the problem of environmental damage due to illegal activities such as illegal fishing, damage to mangrove forests, seagrass ecosystems, coral reefs, and production activities and the fisheries industry that often pays little attention to sustainability aspects so that it is deemed necessary to implement sustainable fisheries management policies that must focus on several urgent matters to achieve Indonesia's blue economy goals. Based on this, as a role model for research purposes, recommendations and research efforts have been made with a roadmap for the sustainable use of pelagic fisheries resources based on Indonesia's blue economy program in the Bone Bay area. Sustainable fisheries management based on the blue economy concept can be developed and applied well through collaboration and synergy with all existing stakeholders consisting of the government, universities, NGOs, and fishing communities.
