Panaji: Jellyfish blooms on the state’s beaches have come to haunt the tourism industry and locals again, as the presence of the dreaded invertebrate has been noticed on a long stretch of shoreline from Baina to Velsao and Betalbatim.
In July, the invasion of the venomous blue bottle jellyfish had troubled tourists and others along the longer stretches of Goa’s coastline.
On Saturday, Drishti Marine cautioned visitors to stay alert and safe on the coastal stretch of Mormugao and north Salcete. “Drishti lifeguards spotted jellyfish which washed ashore along the Baina-Velsao-Betalbatim beach stretch in South Goa on Friday,” an official from the lifeguard agency said.
In North Goa, a villager from Morjim said, “Fishermen casting their nets often find them along with the fish.”
A few factors, like nutrients from manure runoffs, ballast water discharge and contrasting temperatures, are responsible for the growth of jelly fish “A concentration in nutrient levels is one of the factors for their growth,” said R A Sreepada, an NIO scientist.
The occurrence of the jelly fish raises a concern for the tourism and fisheries sectors. “The jellyfish explosion is alarming for coastal fishery as it consumes the food of the bigger fish,” said another NIO scientist Baban Ingole.
