Identifying potentially harmful jellyfish blooms using shoreline surveys

Interactions between jellyfish and aquaculture operations are frequent around the world, with scyphozoan (in particular Pelagia noctiluca) and hydrozoan species documented as causative agents in major fish kills. Identifying areas of major aggregations or incursions of particular species around a co...
