An underwater survey off the Kovalam beach last week revealed an accumulation of ‘ghost nets’ and other remnant marine gear, which, if not removed, could remain a significant threat to marine life forms for centuries, local researchers said.
The three-day survey was conducted by the Thiruvananthapuram-based Friends of Marine Life (FML) in association with SCUBA Cochin, Adhwana, and the South Indian Federation of Fishermen Societies (SIFFS). Lost or abandoned fishing nets, which float around in the sea, or come to rest on the seabed, are often referred to as ‘ghost’ fishing gear.
Significant threat
“We found an accumulation of remnants of nylon fishing nets and thick nylon ropes that are used on ships. They were found at depths up to 5 m. These nets pose a significant threat to marine biodiversity,” FML chief coordinator Robert Panipilla said.
The survey team, which consisted of divers, snapped several photographs which reveal the extent of the threat. The survey also found evidence of the degradation of corals in the region. Of the 12 types, eight have vanished, according to the researchers.
One of the best-known tourist locations in Kerala, Kovalam is also known for the rocky reefs, which are home to a wide range of marine life forms.
Mr. Panipilla demanded that urgent intervention be made to get the ghost fishing nets removed. Apart from Mr. Panipilla and SCUBA Cochin director Justin Jose, two other divers, Jackson Thumpakkaran and Charles, also participated in the underwater survey.
