As a marine biological disaster, the jellyfish blooms has been a hot issue in the field of marine ecology. Hydromedu sae, siphonophore, scyphomedusae, cubomedusae and ctenophore are found in aquaculture ponds or cages, which has a serious impact on aquaculture production. This study integrally describes the harmful jellyfish types and main related hazards to aquaculture, analyzes the possible harms of aquaculture activities on jellyfish blooms. And based on the previous study, we put forward several proposals in prevention of jellyfish disasters in aquaculture.
