How can we reduce bycatch?


Proven solutions do exist, such as modifying fishing gear so that fewer non-target species are caught or can escape. In many cases, these modifications are simple and inexpensive, and often come from fishers themselves. Despite new technologies and industry recognition of the issue, bycatch is still a major problem.

How do I improve my bycatch?

How can unwanted catch be reduced? Bycatch can be reduced through certification to the MSC Fisheries Standard. Fishing activity is often improved during and after certification. Improvements can include contributions to research, modifications to fishing methods or measures to build up fish populations.

What is done with bycatch?

What is bycatch? Fishermen sometimes catch and discard animals they do not want, cannot sell, or are not allowed to keep. This is collectively known as “bycatch.” Bycatch can be fish, but also includes other animals such as dolphins, whales, sea turtles, and seabirds that become hooked or entangled in fishing gear.

What measures have been taken to protect sea turtles from bycatch?

Similarly, we have measures including fishing gear modifications, changes to fishing practices, and fishing closures during certain times and in certain areas to reduce sea turtle bycatch in pelagic longline, mid-Atlantic gillnet, Chesapeake Bay pound net, and Southeast trawl fisheries for shrimp and flounder.

Why is bycatch an issue for the environment?

The taking of bycatch such as turtles and dugong, seabirds and other species that may be unable to sustain any additional mortality also poses a direct threat to the survival of some species or populations of aquatic animals.

How can we solve the problem of overfishing?

Strong fishery management is key to preventing overfishing. Key factors include enforcement of regulations, up-to-date data collection, and monitoring of fish stocks. Fishermen and their communities benefit from well-managed fisheries too because they’re more lucrative and reliable.

How many dolphins are killed as bycatch?

About Operation Dolphin Bycatch Scientific evidence shows between 6,000 and 10,000 dolphins are dying each year due to non-selective fishing methods used to target sea bass.

What is a more sustainable way to fish?

Rod-and-reel fishing results in less bycatch because non-targeted species can be released immediately. Additionally, only one fish is caught at a time, preventing overfishing. For commercial fishers, rod-and reel-fishing is a more sustainable alternative to long lining.

What percent of bycatch is killed?

It is one of the most significant threats to maintaining healthy marine ecosystems. U.S. BYCATCH • Approximately 17-22 percent of what fishermen catch every year is discarded at sea, likely already dead or dying.

How common is bycatch?

While bycatch data is often outdated and inaccurate, researchers estimate that 17-22 percent of U.S. catch is discarded every year, according to the best available data. Bycatch in the U.S. could amount to 2 billion pounds every year, equivalent to the entire annual catch of many other fishing nations around the world.

How many fish are killed by bycatch?

About 40 percent of fish caught worldwide are captured unintentionally and are either thrown back dying or left to die on the boat. This amounts to around 38 million tonnes of sea creatures caught as bycatch every year.

What is bycatch and how can it be reduced?

Fish that are unintentionally caught but still sold in markets with the intended species. Certain characteristics of a target fish species may cause fishermen to avoid bringing them to sale. These include undesirable sex or size. Some species of fish bycatch are protected and thus cannot be sold.

How does bycatch contribute to overfishing?

Bycatch messes up the whole environment. Dumping dead fish and other carcasses overboard draws in ocean scavengers and affects nutrient cycles in the water. And the same types of fishing gear that accidentally kill marine mammals and turtles and birds can also mess up the physical environment.

How does the harvesting of bycatch impact the ocean’s ecosystem?

Harvesting large quantities of bycatch may place sensitive fish populations, such as cod, in jeopardy and interfere with the overall health of ocean ecosystems. Fishers can reduce bycatch by using gear that is designed to trap one species and let others go.

How many animals are killed by bycatch?

When humans overfish, our oceans suffer. In a single year, U.S. fisheries unintentionally catch almost 2,000 federally protected marine mammals, almost 12,000 sea turtles and more than 7,600 seabirds. Worldwide more than 650,000 marine mammals die as fishery “bycatch” annually.

How does bycatch affect sea turtles?

Sea turtles, particularly greens, loggerheads, olive ridley’s, and leatherbacks, and seabirds like albatross, are attracted to the bait and get caught on the hooks or become entangled in the lines and drown.

How many sea turtles are caught as bycatch?

Bycatch Victims It is estimated that 300,000 small whales and dolphins, 50 million sharks and rays and 250,000 turtles die annually as bycatch. Many of these animals are keystone species, which means they play a crucial role in their ecosystem.

Which of the following fishing technologies reduces the impacts of fishing bycatch on sea turtles?

How is bycatch affecting marine life?

Bycatch can slow the reconstructing of overfished stocks, and spot secured species, for instance, whales and sea turtles at extra risk. Bycatch of species like corals and sponges can make harm to secured corals and to significant fish territory.

How does bycatch contribute to overfishing?

How many animals are killed as bycatch each year?

Every year, fisheries around the world unintentionally catch and throw away more than 10.3 million tonnes of sea life: creatures that include fish, shellfish, corals, sponges, marine mammals, seabirds, sharks and sea turtles. 1 It’s called bycatch, and it’s a problem both ecologically and economically.
