Across the world we are seeing evidence of overfishing as we experience declines in species abundance, loss of populations and the increasing demand for our ocean resources. These issues combined mean that the pressure being put on our ocean ecosystems is immense.
Evidence of our presence is seen in the deepest parts of the ocean, found buried in arctic ice and with our carelessness with the tools we use. One such problem is the abundance of ghost nets that can be found in oceans worldwide.
But what is a ghost net?
Ghost nets are fishing gear that has been lost or left in oceans by fishermen. These nets can range in size as they cover everything from fishing lines to fishing cages and fish aggregation devices to nets. This equipment poses a large threat to many different species as they drift through oceans, settle on reefs and entangle anything that comes in contact with them.
Here on Koh Tao we see evidence of these discarded nets throughout the year as we see issues with nets entangled on the reefs, floating mats of fishing gear/trash and in the entanglement in marine life.
Just this year we have removed nets from 3 different reefs, freed entangled animals and rehabilitated 2 sea turtles that were caught entangled in ghost nets.
Whilst ghost nets are still being found it is important that we continue to remove them to promote the health of the ecosystem and reduce the risk that they pose to our oceans and the marine life that we as divers, snorkelers and swimmers want to encounter.
