Montana increases financial penalties for aquatic invasive species violations to strengthen enforcement and protect native waterways from ecological and economic damage.
HB 242 revises the fine structure for violations related to aquatic invasive species in Montana, adjusting penalties that individuals and entities face for introducing, transporting, or failing to prevent the spread of invasive aquatic organisms. The bill has been signed into law as of May 5, 2025. The specific fine amounts and violation categories were restructured to better deter non-compliance and protect Montana's waterways.
Aquatic invasive species cause significant ecological and economic damage to freshwater ecosystems, costing states millions in management and prevention efforts annually. By revising fines, Montana aims to increase compliance with existing regulations regarding boat inspections, water testing, and species reporting—ultimately protecting native fish populations, recreation industries, and water quality across the state.
