Economic Analysis Projexts 10% Loss To Bolbophorus Trematode In U.S.Channel Catfish Industry

摘要

Boibophrus sp. trematodes affect channel catfish production by reducing feed consumption and causing mortalities. In a study, severe trematode infestations were found to cut production 44.5% and lead to major net losses for infected ponds. Annual olsses to Bolbophorus sp. for the U.S. catfish industry were estimated as over 10%. The trematode identified as Bolbophorus sp. can cause significant production losses in commercially raised channel catfish. The encysted trematode, which appears as small bumps under the skin, has been associated with high mortality rates, decreased feed consumption, and poor production efficiency. To assess its economic impact, a disease-monitoring and production efficiency study was conducted by the authors at a commercial catfish operation with reported trematode infestations in the United States.
