Over the past decade, crawfish (often known as crayfish outside the US) production in Louisiana and the surrounding region has grown to become, arguably, the second most valuable sector in US aquaculture behind only catfish. This low-input, environmentally sustainable industry is based on management practices that mimic natural hydrological and vegetative cycles. It is also, however, greatly influenced by the weather and when normal precipitation patterns are disrupted crawfish populations (and harvests) can be significantly impacted. This 2023- 2024 season is a sobering illustration of how severe those impacts can be.
