NMFS Uses Early Genetic Detection Methods for Bitter Crab Disease Amid Low Bering Sea Crab Stocks
Amid unprecedented low abundance levels for Tanner crab and snow crab in the Bering Sea, scientists from the National Marine Fisheries Services (NMFS, or NOAA Fisheries) have been utilizing sensitive genetic detection methods to establish earlier detection of bitter crab disease.
The ailment, which has recently impacted the Bering Sea’s historically large Tanner crab and snow crab fisheries, is caused by microscopic parasites that infect crabs, leading to increased crab mortality rates. Infected crabs are known to taste bitter, hence the name of the disease.
NOAA scientists were able to use these...
