Abstract
This study examines the spread and ecological impact of invasive Flowerhorn cichlids (Amphilophus spp.) in Lake Sampaloc, Philippines, driven by both accidental release and intentional aquaculture practices. Field observations and literature reveal that these highly adaptable and aggressive fish outcompete native species, contributing to biodiversity decline amid increasing pollution, eutrophication, and microplastic contamination. Their phenotypic plasticity allows them to thrive in degraded environments, further exacerbating ecological imbalance. While local communities have begun utilizing Flowerhorns for ornamental trade and potential aquafeed production, such practices risk reinforcing their proliferation. The study highlights the need for integrated management strategies combining biosecurity, pollution control, community-based monitoring, and sustainable utilization to mitigate invasive species impacts while supporting local livelihoods.
