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.
The suckermouth catfish is one type of fish species which is an invasive species. The occurrence of suckermouth catfish population explosion in the waters of Lake Sidenreng had an impact on the sustainability of marine biodiversity as well as an impact on the production of fishermen's catch. This study aims to determine the effect of suckermouth catfish population explosion on the effectiveness of fish filling and the sustainability status of Sidenreng Lake water management. This research was conducted for three months, from June to August 2020 in Teteaji Village and Wette'e Village, Sidenreng Rappang Regency. This study aims to determine the effect of fishing effectiveness and the status of the sustainability of the management of Lake Sidenreng. The effect of population explosion on the effectiveness of fishing was analyzed descriptively based on a comparison of the production of moderate catches on the sustainability status of Sidenreng Lake management using the RAPFISH-MDS (Rapid Appraisal for Fisheries-Multidimensional Scaling) method. Based on the analysis of the suckermouth catfish population explosion in Sidenreng Lake, it has an impact on capture fisheries activities in Lake Sidenreng, namely on fishing gear, fishing operations and production of catches. The status of the sustainability of Sidenreng Lake management based on the RAPFISH MDS sustainability analysis from all dimensional aspects (ecological, economic, social and technological dimensions) shows that the sustainability status of Lake Sidenreng is 51.12 including the fairly sustainable category.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
