Regional Impacts

Ecological ImpactPredation
Gut contents of 15 medusae consisted of bivalve larvae (35%), adult copepods (23%), loricate tintinnids (23%), and fish eggs (15%). In the highest concentrations seen in Lake Borgne, Louisiana, the medusa population had an estimated filtering rate of 6-72% of the water column per day (Graham et al. 2003).
 
Economic ImpactFisheries
During the jellyfish bloom in the Gulf of Mexico during 2000, the shrimp fishery (primarily for the White Shrimp, Penaeus setiferus) was reduced and halted during the months of July and August, due to clogging of nets. Economic losses may have been as high as $10 million (Graham et al. 2003).
