Why are gillnets such a big risk to sea turtles?

Risks to Sea Turtles Gillnetting has been a major source of mortality for all sea turtle species. Turtles encountering a gillnet can quickly become entangled around their head or flippers as they try to escape. Limited use of appendages can impair a turtle’s natural feeding, breathing, and swimming behavior.

Why are gill nets bad?

Enter the world of “Gillnets: An Indiscriminate Fishery.” Although outlawed in some countries, gillnets are still widely used by artisanal fishermen in the developing world. Gillnets are indiscriminate killers that drown virtually everything that becomes entangled in them, from dolphins to sharks to turtles.

How are gill nets used?

A gillnet is used by fishermen throughout the world to catch various species of fish, and scientists frequently use gillnets as a sampling tool to assess fish populations. The nets may be used in salt or fresh water and may be stationary (set net) or mobile (drift net).

Is Gillnetting sustainable?

Gillnet. Gillnets can be sustainable in some cases, for example salmon congregate at choke points that can be walled off without affecting other species. Gill nets that are not set at a particular location and drift with the current are called drift nets. These also have serious issues with bycatch.

What states are gill nets legal?

Large mesh drift gillnets are already banned in the U.S. territorial waters of the Atlantic Ocean and the Gulf of Mexico, as well as off the coasts of Washington, Oregon, Alaska and Hawaii. However, they remain legal in federal waters off the coast of California.

Is fishing nets illegal?

A controversial type of fishing net, blamed for killing endangered sea life off the California coast, will officially be banned beginning January 2023, according to legislation Gov. The nets, however, have been blamed for killings thousands of other sea creatures, including dolphins, sea lions, and whales.

Are gill nets harmful?

Gillnet bycatch negatively affects a wide range of species including turtles, marine mammals, sharks and seabirds. For some of these species like turtles, gillnets are considered the main threat to their survival. Lost gillnets can also be highly detrimental.

Is it legal to fish with a gill net?

Because of their impact on marine life, drift gill nets have been banned in other countries and states. California is the last West Coast state to allow drift gill nets. Voters banned their use in state waters out to three miles offshore in 1990, but they remain legal beyond that in federal waters.

What is the most sustainable way to catch fish?

For commercial fishers, rod-and reel-fishing is a more sustainable alternative to long lining. Another way to prevent overfishing and bycatch is to simply abstain from eating fish and other seafood.

How many turtles died in 2020?

LA PAZ, Mexico— According to newly obtained official data from the Mexican government, at least 1,088 North Pacific loggerhead turtles died in 2020 in Baja California Sur, Mexico, likely because of entanglement in fishing gear. At least 1,977 turtles have died over the past four years.

What’s the problem with gill nets in North Carolina?

Banning gill nets is the first step but when you look at how many fish they take, there’s an even bigger problem. Stats from the most recent year of data available (2017) show that North Carolina harvested more redfish, speckled trout, and flounder than any other state on the list.

Can a gill net catch a mature fish?

But the net doesn’t discriminate or know regulations. Anything that swims into it while it’s deployed is entangled, and in most cases, will thrash itself to death. Gill nets routinely catch juvenile fish that don’t meet minimum size requirements, as well as mature fish that are over slot regulations.

What causes Redfish to die in gill nets?

Parasite infested redfish with open wounds and scars, clearly caused by gill nets (and in some cases, with netting still caught in their gills). We’ve watched as nets decimate our creeks, hauling hundreds of trout out daily, leaving only dead fish that didn’t survive the netting.

How is gill net mortality in North Carolina?

North Carolina only has one study for discard mortality from gill nets, and the only species that was evaluated was Summer Flounder. In 2018, State observers recorded a 24% discard mortality of flounder in gill nets. This number does not include shrimp trawl bycatch or even statistics of fish that died after being re-released.
