Caught in the Nets: The Complexities of Entanglement in Fishing Gear

Entanglement in fishing gear poses significant risks to marine life. It can cause injury, suffering, and often death for trapped animals.


Entanglement occurs when marine creatures get caught in active, discarded, or lost fishing equipment, such as nets, lines, and traps. This problem affects large ocean inhabitants like whales and sea turtles and encompasses fish, birds, and smaller sea life.


Wildlife entanglement disrupts natural behaviors, leading to dire consequences such as impaired movement and reduced ability to forage and escape predators. It can also lead to severe injuries and increased vulnerability to threats like vessel collisions. With our oceans playing host to vast ecosystems, the health of our marine life is a crucial indicator of environmental well-being. Addressing entanglement involves prevention, timely response, and promoting sustainable fishing practices to ensure the longevity and diversity of marine species.


The Silent Threat: Entanglement Risks In Our Oceans

Deep in the blue serenity of the ocean, a silent threat lurks unseen, ensnaring marine creatures in a deadly grip. Entanglement in fishing gear is an invisible enemy that turns the habitat of ocean dwellers into a dangerous trap. Each year, countless animals suffer from the risk of entanglement, leading to injury and, often, a tragic end.

Deadly Debris: The Perils Of Lost Gear

Imagine the sea floor littered with abandoned nets and lines, entrapping anything that moves. These remnants of fishing activities, known as ghost gear, continue to capture marine life long after being discarded.

  • Marine Mammals: Whales and seals can get tied in this material.
  • Sea Turtles may get wrapped in lines or nets, restricting movement.
  • Fish: Schools can be decimated without a predator in sight.

Lost fishing gear does not just fade away; it persists, wreaking havoc beneath the waves.

Ghost Fishing: The Hidden Killers

Ghost fishing occurs when forgotten gear keeps catching animals. It’s an endless cycle where captured creatures attract others, leading to more deaths.

Species Affected

  • Fish
  • Crustaceans
  • Marine Birds


  • Population decline disrupted ecosystems
  • Reduced numbers, a threat to species survival
  • Entanglement, loss of life

Without human intervention to remove this deadly debris, the killing cycle of ghost gear could continue indefinitely, threatening the very fabric of ocean life.

Spotlight On Whales: The Giant Victims Of Entanglement

Imagine swimming in the vast ocean, free and majestic. Now imagine you suddenly trapped by invisible walls that tighten with each move. This is the reality for many whales caught in an artificial web—lost or discarded fishing gear. These giants, vital to our marine ecosystems, suffer silently, their plight often unseen beneath the waves.

Tracking The Blue Whale’s Burden

Blue whales, grand and serene, roam the cold waters of the earth. Yet, their size offers no protection against the ropes, and nets ensnare them. Satellite tagging reveals the harsh truth of their journeys:

  • Thousands of miles swum with dragging gear
  • Strain leading to exhaustion and malnutrition
  • Scarce human sightings mean fewer rescue chances

Tagging efforts reflect their suffering and guide research and rescue operations.

Entangled Marine Ecosystem: Beyond The Ocean Giants

Images of majestic whales come to mind when we picture entanglement in fishing gear. Yet, the ocean’s lesser-known inhabitants suffer as well. This hidden crisis reaches far beyond the giants of the sea, touching every part of the marine ecosystem. Let’s explore the often-overlooked victims of entanglement.

Collateral Damage: Unsuspecting Prey In Nets

Entanglement does not pick favorites. Every creature in the sea can become tangled. This includes small fish and invertebrates, which often go unnoticed. These animals face severe injuries or even death when caught in nets. As a result, entire food chains can get effect throughout the ecosystem.

  • Small Fish: Vital food sources for larger species and humans alike.
  • Invertebrates: Key players in nutrient cycling and sedimentation.
  • Crustaceans: Economically significant yet vulnerable to becoming bycatch.

Seabirds, Turtles, And More: The Wider Impact

Entanglement extends to creatures above and beneath the waves. An array of species, from seabirds to sea turtles, face this danger.


  • Seabirds
  • Sea Turtles
  • Dolphins & Seals

Impact of Entanglement

  • They can drown if they dive and get caught in submerged nets.
  • They may suffer from mobility reduction or inability to reach the surface of air.
  • Can sustain wounds, infections, or drown when entangled in fishing lines.

Ocean Plastics: From Convenience To Curse

Once hailed as a marvel of modern convenience, plastic has become an oceanic curse—lightweight and durable, plastic items journey from our homes to the seas. In the marine environment, they transform into deadly traps for unsuspecting creatures.

Chronic Entanglement: Slow Strangling Of Marine Life

The menace starts with a discarded fishing net or a fragment of plastic rope. Over time, these plastics become invisible noses for marine animals like turtles, seals, and dolphins. Victims of chronic entanglement suffer a slow and painful death, often enduring wounds, infections, and starvation due to restricted movement.

  • Physical Harm: Deep cuts, limited mobility.
  • Starvation: Hindered hunting abilities.
  • Infections: Wounds lead to disease.

A Lifecycle Of Plastic: From Pollution To Predator Trap

Plastics in the ocean break down but never entirely disappear. What starts as a bottle or bag can end up as microplastics ingested by marine life. Larger pieces of plastic, like nets, ensnare predators and prey alike, upsetting the ecosystem.


  • Initial Pollution
  • Breakdown Process
  • Microplastic Stage

Effect on Marine Life

  • Entanglement, ingestion.
  • Toxic chemicals are released, and small particles are ingested.
  • Bioaccumulation up the food chain.

Entangled creatures become unintentional lures for predators who get caught in the debris. This cycle of entrapment and predation continues indefinitely, making plastics a relentless predator trap.

Economic Implications: The Cost Of Lost Fishing Gear

Entanglement in fishing gear is more than a conservation concern; it’s a severe economic burden. The loss of fishing gear, often termed “ghost gear,” impacts fisheries’ balance sheets and harms the environment, leading to a double-edged sword of financial and ecological costs.

Financial Fallout For Fisheries

Fisheries face direct economic losses when gear is lost. This isn’t just about the price of nets, lines, and traps. It includes the potential catch that’s never landed. Here’s how the numbers add up:
