The Effect of Suckermouth Catfish (Pterygoplichthys sp.) Population Explosions on the Effectiveness of Fishing and the Sustainability Status of Sidenreng Lake Waters

Abstract

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 RAPFISHMDS (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.
