KEY WORDS: Fishermen, ecological impact, invasive species, socio-economic impact, lagoon systemABSTRACT
The invasion of the sailfin catfish has caused serious ecological and socioeconomic problems in diverse global ecosystems. This study evaluates the impact of this invasive species in the Champayán Lagoon System (CHLS), considering ecological and socioeconomic aspects as well as the perception of local fishermen. Semi-structured interviews were conducted to gather information on the socioeconomic conditions and perception of the impact of the sailfin catfish. According to the results, fishermen report a high abundance of sailfin catfish, associated with a notable decrease in the catch of commercial fish. In addition, habitat alterations (water quality and erosion), damage to fishing equipment, and negative effects such as physical injuries and mental stress on fishermen were identified. These findings highlight the urgent need to develop and implement management and control strategies to mitigate the impact of this invasive species in order to improve the quality of life of the inhabitants of the affected fishing communities.
