A sea turtle entangled in a ghost net. Ghost nets are fishing nets that have been abandoned, lost, or otherwise discarded in the ocean, lakes, and rivers. [1] These nets, often nearly invisible in the dim light, can be left tangled on a rocky reef or drifting in the open sea.
The sea animal's aquatic ecosystem may also collapse due to the destruction of the food chain. Additionally, ghost fishing is a major threat due to capture fisheries. [16] Ghost fishing occurs when a net, such as a gill net or trawl, is lost or discarded at sea and drifts within the oceans, and can still act to capture marine organisms. [16]
Ghost nets are fishing nets that have been abandoned, lost, or otherwise discarded in the ocean, lakes, and rivers. [15] These nets, often nearly invisible in the dim light, can be left tangled on a rocky reef or drifting in the open sea. They can entangle fish, dolphins, sea turtles, sharks, dugongs, crocodiles, seabirds, crabs, and other ...
Known as ghost nets, these entangle fish, dolphins, sea turtles, sharks, dugongs, crocodiles, seabirds, crabs, and other creatures, restricting movement, causing starvation, laceration, infection, and, in those that need to return to the surface to breathe, suffocation. [56] There are various types of ocean plastics causing problems to marine life.
Another threat to organisms lurking in the deep ocean is ghost fishing, and bycatch. Ghost fishing is the term that refers to any abandoned fishing gear in the ocean that continues to entangle and trap marine organisms. Gill nets for example, have been recorded tangled around deep sea corals and continue ghost fishing for extended periods of ...
Bottom trawling, generally a commercial fishing technique, involves dragging a large net that herds and captures a target species, such as fish or crabs. [66] During this process, the net damages the seafloor by scraping and removing animals and vegetation living on the seabed, including coral reefs, sharks, and sea turtles. [67]

Drift nets can be many kilometres long. Because drift nets are not anchored to the sea bottom or connected to a boat, they are sometimes lost in storms and become ghost nets. Dropline – a fishing line with one or more hooks, held vertically in the water column with weights and generally used on the continental shelf and slope. Several ...
