“…The pelagic fishing productivity in these waters is very high (Nurdin et al 2017;Putri and Zainuddin 2019). Skipjack tuna (Katsuwonus pelamis) is one of the critical economic valuable fish resources, which is the primary target of fishing (Putri and Zainuddin 2019;Putri et al 2018a;Putri et al 2018b). Makassar Strait is part of the Fisheries Management Area (FMA) 713 and has recorded the potential of skipjack tuna fish FMA 713 that reached 419,342 tons in 2015 (DKP 2016).…”

Abstract. Putri ARS, Zainuddin M, Musbir, Mustapha MA, Hidayat R. 2021. Mapping potential fishing zones for skipjack tuna in the southern Makassar Strait, Indonesia, using Pelagic Habitat Index (PHI). Biodiversitas 22: 3037-3045. Southern Makassar Strait is one of the potential fishing grounds for skipjack tuna in the Indonesian waters. Oceanographic factors become the primary factors that limit the distribution and abundance of fish. The study aimed to identify the relationship between fish distribution with sea surface temperature (SST) and primary productivity (PP) and map out the potential fishing grounds of skipjack tuna in the southern Makassar Strait. It used pelagic habitat index (PHI) analysis, which is strengthened by the results of correlation analysis in the form of generalized additive models (GAM) and Empirical cumulative distribution function (ECDF) analysis. The results showed that the distribution of skipjack tuna was significantly associated with the preferred range of SST 29-30.5°C and PP 350-400 mg C/m2/day. The potential fishing zone is well established near the coast to offshore of Barru and Polman waters (3°-6°S and 117°-119°E), with the peak season in May and October. The spatial pattern of potential fishing grounds for skipjack fishing is associated with hotspots (oceanographic preference), leading to increased feeding opportunities. This study suggests that the spatial pattern of high potential fishing zones could improve fishing, management, and conservation strategies along the southern Makassar Strait.

“…Indonesia has a central role in the global tuna fisheries sector [2]. Skipjack (Katsuwonus pelamis) is one of the fishery commodities in Indonesia, which has significant economic value [3]. The average contribution of skipjack tuna to the total production of Indonesian capture fisheries reaches 6.04%, and total global skipjack production reaches 12.8% in the period 2000-2016.…”

This study aims to analyze the aspects of technical, social, and economic typologies of skipjack fisheries at Nizam Zachman oceanic fishing port, Jakarta. This research expected to provide information for decision-making in formulating policies in skipjack fisheries activities, thus they remain sustainable—this research conducted at Nizam Zachman oceanic fishing port, Jakarta from August 2019 to February 2020. The method used in this research is the survey method by interviewing the respondent through questionnaires for 100 respondents. The sampling method was done randomly, and the data were analyzed by descriptive qualitative. The social typology shows the orientation of Nizam Zachman as an industrial ocean fishing port is for commercial purposes. The main productive age level of fishers ranges from 35-39 years (33%) and the last education is a primary school (46%). Regarding the work experience, 38% had been fisher between 16-20 years. The technical typology shows the fishing gear that operated to catch skipjack at Nizam Zachman are purse seine, longline, also carrier vessel. In general, 74% of the size fleets were in 100-200 GT and the length of trips in 1-2 months (48%). The fishing ground area is in 572, 711 and 712 FMA. The economic typology shows skipjack production/trip by purse seine was 54%, longline (1%) and carrier vessel (57%).

Spatial and temporal studies on the distribution of small pelagic fish by applying oceanographic parameters are essential for fisheries management. An understanding of the spatial characteristics of small pelagic fish distributions is important to optimize the sustainability of marine resource utilization. This study examined the characteristics of small pelagic fish fishing grounds through the analysis of oceanographic parameters using remote sensing satellite data and generalized additive model. Remote sensing satellite data (SST and chlorophyll-α) covering the area of Makassar Strait were obtained from NASA databases, with a spatial resolution of 4 km and monthly temporal resolution. Data on the geographical location and catch volume of small pelagic fish were obtained from a fisheries survey in the Makassar Strait. Remote sensing satellite data and fisheries survey data were plotted graphically to determine the environmental conditions at the sites where the small pelagic fish were caught. Catch volume and catch positions were mapped to show fish distribution. The results show that the highest point was around Barru waters with a catch of 30.70kg - 36.75kg. Small pelagic fish were caught in the SST range between 29.82° C - 31.32°C and mostly caught in chlorophyll-a between 0.34 mg/m3 - 0.62 mg/m3.
