Ghost Fishing – A nightmare in the ocean
EDITOR: When we as humans hear the word “ghost”, the first thing that might come to our mind is the disembodied spirit of a dead person who haunts the living, or maybe a horror movie “House on Haunted Hill”. However, in the ocean there is a ghost that haunts and assassinates marine animals, this ghost is “ghost fishing”.
Ghost fishing is the accidental capture of aquatic organisms by fishing gear; for example fishing nets, fishing lines, traps, and pots that have been lost or discarded into the sea, which continues to entangle or trap aquatic animals. Marine animals are already suffering from ghost fishing. According to the Food and Agriculture Organization (FAO), abandoned, lost or discarded fishing gear in the ocean make up around 10 percent (640,000 tonnes) of all marine litter.
Ghost fishing kills 650,000 animals a year. According to a National Geographic article on August 29, 2018, more than 300 Olive Ridley sea turtles died in Mexico after becoming entangled in a fishing net. In January of 2019, a huge ghost fishing net estimated to be more than 100 ft long washed up on a beach in Corn Wall, luckily, dozens of crabs and lobsters were rescued.
Ten percent of the world’s population depends on fisheries for livelihoods, and 4.3 billion people are reliant on fish for 15 percent of their animal protein. Climate change is already causing coral bleaching and ocean acidification, eight million tonnes of plastic is already in the ocean killing marine animals and it is estimated that by the year 2050 there would be more plastic than fish in the ocean if nothing is done urgently, eutrophication is causing an outbreak of algae, depleting the oxygen in streams and the ocean, ghost fishing is causing entanglement, how many more nightmares can these marine animals take?
Here are some solutions for ghost fishing:
- Fisherfolks should report lost fishing gear in a timely manner. Modern nets and fishing lines are made from synthetic materials, such as monofilament or nylon, which take decades, even hundreds of years to decompose in water. Abandoned nets that remain anchored become weighted down with sea life, making them more difficult to remove.
- Drones can be used to identify lost fishing gear that might be floating in the ocean. The coast guard can also play an active role by helping to recover any lost fishing gear.
The greatest rapper of all time, Tupac Shakur, has a song name “Changes”. The song begins with “I see no changes”, can we make some changes to protect and conserve the ocean to help feed the world’s population, to sustain livelihoods, and to protect these animals from going extinct?
