Fishermen said that the jellyfish blocked their fishing nets.
"We couldn't helping removing the jellyfish one by one."
Jellyfish are mostly seen in large numbers as of February till the end of April, they added.
"This is actually their mating season as the climate gets hotter."
Abdullah Hassan, a fisherman in RAK, said jellyfish always flock to the warm beaches.
Ali Saeed, an Emirati fisherman, said the light from the jellyfish scared the fish away, "this results in a loss for all fishermen."
