Abstract:
Jellyfish bloom implies an economic issue directly affecting tourism, fishing, aquaculture, and oil plants. Although many methods have been used to repel jellyfish arrivals to our coasts, such as nets or water currents, none seems to be a permanent solution. In this paper, we test the effect of applying a medium-frequency Electromagnetic (EM) field on jellyfish behaviour, specifically, their movement. A coil inside a jellyfish aquarium is used to generate the EM field. A current generator powers the coil. As an indicator of jellyfish movement, jellyfish pulsations are counted in the presence or absence of the EM field. Selected jellyfish species (Catostylus mosaicus) present two types of colouration, blue and brown. According to the results, blue jellyfish showed different behaviour than brown jellyfish. Blue jellyfish have about 50 pulses without an EM field, decreasing slightly in the presence of an EM field. On the other hand, brown jellyfish pulses about 40 times without an EM field, dropping to values below 20 when the EM field is applied. As suggested by the obtained data, we can propose different systems to prevent jellyfish from getting close to the shore, based on the use of coils to generate EM fields and bottom water current.
