Eco details:
Although some U.S. crawfish are captured in the wild, most are farmed in rice fields or ponds. Crawfish eat natural vegetation, so no feed or chemicals are needed.
Crawfish are also farmed in China, where they are considered an invasive species and escapes have disrupted aquatic ecosystems.
