Sea turtle entangled in a ghost net. Ghost gear is fishing gear that has been left or lost in the ocean. [7] [15] The gear can potentially continue to catch or entangle any species of marine life as it drifts through the water or snags on rocky reef, eventually killing the entangled organism through laceration, suffocation or starvation. [16]
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]

A turtle entangled in a ghost net The Great Pacific Garbage Patch in 2017. In Seaspiracy, narrator Tabrizi criticises a public focus on plastic straws, stating that they only account for 0.03% of ocean plastic. He contrasts this with fishing nets, saying they make up 46% of the Great Pacific Garbage Patch. The fishing net statement derives from ...
The physiology of underwater diving is the physiological adaptations to diving of air-breathing vertebrates that have returned to the ocean from terrestrial lineages. They are a diverse group that include sea snakes, sea turtles, the marine iguana, saltwater crocodiles, penguins, pinnipeds, cetaceans, sea otters, manatees and dugongs.
A loggerhead sea turtle exits from a fishing net through a turtle excluder device (TED) One of the most significant and contemporary threats to sea turtles comes from bycatch due to imprecise fishing methods. Long-lining has been identified as a major cause of accidental sea turtle deaths.
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 ...
