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]
Bycatch is a large contributor to sea turtle deaths. [43] Longline, trawl, [44] and gillnet fishing are three types of fishing with the most sea turtle accidents. Deaths occur often because of drowning, where the sea turtle was ensnared and could not come up for air. [45] Cubs of endangered Saimaa ringed seal also drown to fishing nets. [46]
This is the heartwarming moment fishermen cut loose a turtle that was tangled in a loose net. Anucha Boontaeng, 42, noticed the turtle struggling as it floated in loose nets in the Andaman sea ...
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 ...
The second is the problem of "ghost nets", i.e. the many abandoned fishing nets drifting with the currents, which retain their lethal properties for several years, even decades. In particular, they trap cetaceans and sea turtles, which drown because they can't come to the surface to breathe. [59]
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 ...
At sea, marine turtles can be targeted by small scale subsistence fisheries, or become bycatch during longline and trawling activities, or become entangled in ghost nets or struck by boats. An ambitious project, called the Global Marine Species Assessment, is under way to make IUCN Red List assessments for another 17,000 marine species by 2012.
